Hiiiiii! Hope your week isn’t giving you too much grief - and if it is, hopefully these wee cookie sandwiches make it better! I’ve been laying low recently, trying to get on top of what kind of feels like a never ending job list - we hid at home over the weekend to get some of it done. They aren’t exciting or big jobs - just a whole lot of those dumb ones that you let build up and suddenly feel like you’re drowning in. I’m sure it’s not just me who gets this? February is classic intense homesick time for me, so I kind of just stick my head down, keep to a routine, make sure I get out of the house enough, and ride it out. It seems to be working. Cookies definitely help.

These wee numbers come from my friends over at Cook: Real Food Everyday magazine! They are the savoury sister to Bake from Scratch, and each issue is jammed full of so many amazing dinner ideas - some of our absolute faves come from there! After a day of recipe testing baking recipes, I find it super relaxing to just follow a recipe for dinner, so am always on the lookout for inspiration. You can subscribe through their website - they have a digital version too if you’re not based in the states!

Alongside all their amazing savoury content, the magazine also has a couple of recipes perfect for weeknight baking - these Oatmeal Chocolate Chunk Sandwich Cookies with Mascarpone Filling are from their latest issue! They are super simple to make, and the mascarpone filling really just takes them over the edge to make the perfect, easy to make cookie sandwich. I couldn’t help but doctor the recipe just a teeny bit - I used some muscovado sugar in place of some of the brown, used half old fashioned oats and half quick cooking to give some chew, and also added a little chocolate. All of these variations are totally optional - I will list the alternatives in the notes!

A few wee tips:

  • A couple of pointers from Cook: Make sure that your mascarpone and butter are the same temperature when you make the cookies, to ensure that the frosting comes together nicely. If it seems like it is splitting a little, I sometimes take out a tablespoon or two and melt it in the microwave, then whip it back into the mixture to help even out the temperature.

  • I like to roughly chop some of my chocolate for this, to help distribute it a little! I pulled some of the chunks out of the batter and put them on top of the dough balls to ensure some chocolate on the tops of the cookies!

  • The cookies alone are bomb. I made a batch as a test and they got demolished, so if you don’t want to fill them, then you can have them as is!

  • I subbed some of the quick cooking oats for old fashioned oats, which have a bit more substance to them. I just did half of the amount by weight - if you only have quick cooking oats, or only old fashioned, either work! I probably should have accounted for the change in weight with subbing old fashioned oats, but I winged it and it worked just fine. Haha. Whoops.

  • I also added chopped chocolate - leave it out if you want!

  • The final sub I made was swapping a little of the light brown sugar for muscovado - if you do not have this on hand, use the same amount of brown sugar in place of muscovado!

  • The cookies might come out of the oven looking not quite perfectly round - for sandwich cookies I like to have them as round as possible! To help correct this, I take a round cookie cutter bigger than the cookie, and use it to nudge the still warm cookie into a round shape.

  • You may have more cookies than you have baking sheets for. This happens to me often - just hold off scooping all of them, and then once the first batch is out and cooled enough to move to a rack, re-use that baking sheet.

Oatmeal Chocolate Chunk Cookies
285g unsalted butter, at room temperature
200g light brown sugar
130g muscovado sugar, or light brown sugar
1 egg, room temperature
2 tsp vanilla (I used vanilla bean paste)
140g quick cooking oats
140g old fashioned oats (or quick cooking oats)
190g all-purpose flour
1 tsp baking soda
3/4 tsp pumpkin pie spice or cinnamon
1/2 tsp kosher salt
250g good quality dark chocolate (I used 70% wafers), roughly chopped (see notes)
Flaky sea salt for finishing

Mascarpone Filling
115g unsalted butter, at room temperature
225g mascarpone cheese, at room temperature
2 tsp vanilla (I used vanilla bean paste)
1/2 tsp salt
360g powdered sugar, sifted

 

- PROCESS -

OATMEAL CHOCOLATE CHUNK COOKIES

Preheat the oven to 375° / 190°c. Line three baking trays with parchment paper.

In the bowl of a stand mixer fitted with the paddle attachment, beat the butter, brown sugar, and muscovado sugar on medium high until light and fluffy, approximately 4 minutes. Add the egg and vanilla, and beat until combined. Scrape down the bowl to ensure it is evenly incorporated.

In a medium bowl, whisk together the oats, flour, baking soda, cinnamon, and salt. Add to the bowl of the stand mixer, and mix until just combined.

Remove the bowl from the mixer and add the chocolate, incorporating by hand.

Scoop the dough into 2 Tbsp balls (I used a #16 scoop). Roll into balls with your hands, and space evenly on a baking tray. (I fitted about 8 per sheet).

Bake the trays, one at a time, for 10 to 12 minutes, or until golden brown. Sprinkle with flaky sea salt as soon as they come out of the oven. Allow to cool on the tray for 5 minutes, then transfer to a wire rack to cool completely.

Repeat the baking process with the remaining baking trays until all of the cookies are baked.

 

MASCARPONE FILLING AND ASSEMBLY

In the bowl of a stand mixer fitted with the whisk attachment, beat the butter, mascarpone, vanilla, and salt on medium speed until combined, 2-3 minutes. Add the sifted powdered sugar, and beat for a further 2 minutes, until light and fluffy.

Transfer to a piping bag fitted with a french star tip (I used Ateco #865).

Pair up the cookies into pairs of equal sizes. Pipe a round of filling onto one half of the cookie, and sandwich with the second half, pressing down gently.

Refrigerate until serving. Store leftovers in an airtight container in the fridge.

Hi hi! I’m back with a wee variation on an old friend of mine - this Devil’s food Bundt Cake with a Bay Caramel. One of my very favourite chocolate cakes comes from my friend Stella’s book - it is rich, the most amazing texture, and comes together in one bowl. The layers bake beautifully flat, which makes it a dream to stack up into a layer cake.

After I made a bundt cake a few weeks back, I haven’t been able to stop thinking about them - I love how easy they are, that they don’t need a frosting, and that the fancy pan does most of the work. I wanted to develop a go-to chocolate bundt cake, but thought maybe first I could try and see if this Devil’s food cake could be adapted for a bundt recipe. And not only did it turn out amazingly, but the quantity of batter required for the layer cake happened to also be the perfect amount needed for a bundt cake. I was expecting a huge amount of recipe testing, but since this worked, and it’s one of my faves, I figured I might as well stick with this!

This cake was originally going to have a tahini caramel on it, but my friend tagged me in a post recently that had doughnuts with a bay leaf caramel, so I figured I needed to give that a try. The bay gives a beautifully subtle flavour to the caramel - not too overpowering, but a slight variation on the traditional caramel taste. It goes perfectly with the not too sweet cake. The cake is amazing alone - perfectly dense, so if you don’t want to make the caramel to go alongside, a quick dust of icing sugar would be delicious too.

A few wee tips:

  • If you need cup or oz measurements for this, you can see the original post. I adapted the method just slightly to make this done in one bowl rather than a pot. It’s super easy to just plonk the bowl down on the scale and add everything in!

  • I used the Bavaria pan by Nordicware

  • Bundt cakes can be a bit intimidating. You have to spray the shit out of with baking spray, then dust it with either flour or cocoa powder. Alternatively I like the baking spray with flour and then a little dust of cocoa. 10 minutes also seems to be the sweet spot in terms of cooling time to get the cake out of the pan - set a timer as soon as you take it out of the oven.

  • I used a 10 cup bundt pan - the batter will all fit if you want it to, but I found it best to hold back just a little to make sure it won’t overflow in the oven (about 1/4 cup) - I baked it in a little ramekin and had a little snack!

  • Ideally you want to give the caramel time to cool - if it is too thick to pour, you can quickly zap in the microwave for 30 seconds at a time.

  • This cake is super moist, so keeps super well - just store in an airtight container at room temperature.

 

 

One Bowl Devil's Food Bundt Cake with Bay Leaf Caramel

- Makes one Bundt Cake, Serves about 14 -

Devil’s Food cake From Bravetart: Iconic American Desserts

Devil’s Food Bundt Cake
340g unsalted butter, cubed
340g hot coffee, or boiling water and 2 tsp instant coffee
85g Dutch Process Cocoa
170g finely chopped dark chocolate (I used 70%)
450g light brown sugar
1 Tbsp vanilla
1 tsp salt
6 eggs, cold
40g egg yolks (about two large egg yolks)
255g All-purpose flour
1 Tbsp Baking Soda

Bay Leaf Caramel
180g heavy cream
8 bay leaves, roughly chopped, plus four more to infuse while cooling (I used fresh)
300g sugar
135g Butter, at room temperature
2 tsp flaky sea salt

- PROCESS -

DEVIL’S FOOD BUNDT CAKE

Preheat the oven to 350° / 180°c. Spray a 10 cup bundt pan with baking spray or baking spray with flour, and dust well with dutch process cocoa.

In a large bowl, combine the hot coffee and butter. Whisk until the hot liquid has melted the butter. Add in the cocoa and chopped chocolate, and whisk to combine until the chocolate is melted. Add the brown sugar, vanilla, and salt, and mix to combine.

Add the eggs and yolks, whisk well to combine, then sift in the flour and baking soda, and stir well until mixed.

Place the bundt pan onto a baking sheet. Add the batter to the bundt pan, reserving about a quarter of a cup to ensure it does not overflow (see notes). Tap the pan on the counter a few times to help remove any large bubbles.

Bake the cake for 55-60 minutes, or until a skewer comes out clean and the cake registers 210°f / 100°c on a thermometer.

Remove from the oven and allow to stand for exactly 10 minutes before inverting onto a cooling rack. Allow to cool completely.

BAY LEAF CARAMEL

Place the heavy cream in a medium saucepan. Place over medium heat, and bring to just shy of a simmer. Remove from the heat, add the roughly chopped bay leaves, cover the pan, and steep for 30 minutes. Remove the bay leaves, and re-weigh the cream. Top up to 180g if needed. Return the pan of cream to a low heat while you prepare the rest of the caramel.

In a medium heavy bottomed saucepan, place the sugar over medium heat, stirring occasionally with a whisk. The sugar will start to form clumps, then begin to melt. Cook until is it amber in colour, then remove from the heat and immediately add all of the butter. Be careful as the caramel will bubble rapidly. Once the butter is incorporated, add the cream and whisk until well incorporated. Whisk for a further minute to ensure it is emulsified. Stir in the salt, and pour into a glass jar. Add the four bay leaves. Allow to cool completely.

ASSEMBLY

Place the cooled cake onto a wire rack over a sheet pan. Remove the bay leaves from the caramel, and warm if needed until it is a pouring consistency.

Pour the caramel over the cake until it is coated. You may not need all of it. Allow to sit for a few minutes to settle.

Store leftovers in an airtight container at room temperature.

It’s always around this time of year that it feels like winter is never, ever going to end. February really tends to drag it’s butt round here - today we had snow, then freezing rain (never seen that wee symbol on my weather app until I moved here, and it’s not a fun one), so it’s kind of hard to motivate myself to do anything other than stay inside with the cat and eat soup. Which is exactly what we have been doing. Whoopsies.

I’ve been meaning to make this cake for a while now. Passionfruit is my ultimate fave fruit of all time, but almost impossible to find in NYC. It grows like crazy in New Zealand, and so I guess I just assumed it would be easy to get here, but unfortunately this is not the case. However, my local supermarket has just started stocking it in pouches (most exciting day ever when I realised), so I’m super super excited to start sharing more passionfruit recipes! I am dying to add the curd as a ripple in an ice cream, or as the base for a passionfruit cream filling in a cream puff.

If you haven’t made passionfruit curd before, it’s almost exactly the same process as making lemon curd. I removed the seeds to make the curd, then added back in a few tablespoons of them, which is nice to give a little crunch without being too overwhelming. The thing I love about passionfruit curd is that the fruit is tart enough to stand up to the egg yolks, so you don’t run the risk of the eggy taste you can get with other fruit curds, but still get the delicious flavour and velvety texture from the yolks.

The rest of the decisions from there in terms of flavour pairing were super simple - I made a basic vanilla bean cake, and paired it with a silky vanilla bean Swiss meringue buttercream. Both of these serve as the perfect base to make the curd filling really shine.

I finished the cake with an ombre finish, which is one of my favourite ways to ice a cake. You essentially plop the buttercream on, creating a gradient, then smooth it all with a bench scraper to create a beautiful ombre effect. If you haven’t tried it before it’s definitely worth giving a go - it’s super easy, but really really effective.

This cake would make the most amazing birthday cake, or anytime cake! Happy February! I hope it’s less dreary than mine.

A few wee tips:

  • This cake was made with the reverse creaming method - instead of creaming the butter and sugar together, you slowly incorporate the butter into the dry ingredients. This means that the flour particles get coated in the butter, inhibiting the formation of gluten, and giving you a tender crumb. With that being said, I did go for a slightly denser textured cake, in order to have something which stands up to the filling and buttercream.

  • For the passionfruit filling, I used pulp I found in a pouch at my local supermarket. The recipe for the curd does make quite a lot because I think it’s an amazing thing to have on hand. You can either use frozen passionfruit pulp for this recipe (don’t worry if it doesn’t have seeds in it), fresh, or packaged pulp. If you don’t like seeds in your curd, they can be left out.

  • I use Fat Daddio’s Cake pans - they aren’t too expensive, and give me a clean cake every time!

  • I like to divide the batter between the pans by weight. To do this, you zero the scales with one of the empty cake pans on it, then once you have eyeballed your dividing of the batter, you can weigh each pan to ensure that they have the same weight of batter in them. Note that this only works if your cake pans are identical.

  • If I can, I like to make the cake ahead of time, then wrap and store in the fridge until I am ready to assemble. Level it off just before you assemble.

  • I decorated this with an ombre style buttercream, then put the remainder of the buttercream (both the white and yellow) into a piping bag fitted with a wilton 1M tip, and piped on the little blobs at the top. Fill and crumb coat the cake, and then divide the rest of the buttercream 2/3 to 1/3 and colour the 1/3 portion yellow.

- PROCESS -

CAKE LAYERS

Preheat the oven to 350°f / 180°c. Grease three 8” cake pans, and line with parchment paper on the bottom.

In a medium bowl, whisk together the eggs, egg yolks, vanilla, milk, and yoghurt.

In the bowl of a stand mixer fitted with the paddle attachment, combine the flour, sugar, baking powder, and salt. Mix briefly to combine.

With the mixer on low, add the butter a cube at a time, until fully incorporated and the mixture looks like sand.

Add half of the wet ingredients into the mixer. Mix until just combined, then add the second half of the wet ingredients. Mix on medium speed until just combined. Remove the bowl from the mixer and give a few folds with a rubber spatula to ensure that no dry ingredients remain.

Divide the batter between your three cake tins (I prefer to do this by weight - see notes). Bake for 35 to 40 minutes, or until the cakes are springy to the touch, and a skewer inserted into the middle comes out clean.

Remove from the oven and cool for 15 minutes in their pans, then turn onto a wire rack and allow to cool completely.

 

PASSIONFRUIT CURD FILLING

Place the Passionfruit pulp in a blender or food processor. Pulse a few times to separate the seeds from the pulp. Strain through a sieve into a medium saucepan. Reserve the seeds.

Add the remainder of the ingredients to the saucepan, and place over medium heat. Whisk well to combine. Place over medium low heat, and cook for 30 minutes, stirring frequently, until the curd has thickened significantly - enough that it coats the back of a spoon well, and when you run a finger through, it leaves a very clear track.

Strain through a fine mesh sieve into an airtight container, and stir in 1-2 Tbsp of the reserved passionfruit seeds. Place a piece of plastic wrap over the surface of the curd. Refrigerate until completely cool, ideally overnight.

VANILLA BEAN SWISS MERINGUE BUTTERCREAM

Place the egg whites, sugar and salt in the bowl of a stand mixer or a heat proof bowl. Place over a pot of simmering water, ensuring that the water does not touch the bowl. Heat, whisking constantly, until the mixture registers 160˚f / 70˚c on a thermometer and the sugar has dissolved. Carefully transfer the bowl to the mixer, and fit with the whisk attachment. Whip the egg whites on high until they are snowy white and fluffy, 8-10 minutes. Add the butter one chunk at a time. The mixture may look curdled - but just keep mixing! Once all the butter is incorporated, mix on high for a further 10 minutes. Add the vanilla and mix until incorporated.

Once the buttercream has finished mixing, and is smooth and silky, add in the vanilla bean paste. Mix for a further 2-3 minutes, then switch to the paddle attachment and mix on low for one minute to remove any air.

ASSEMBLY

Level off the cake layers. Transfer some of the buttercream to a piping bag fitted with a medium round tip - this will be used to make a buttercream dam to hold in the passionfruit filling between layers.

Secure one of the layers of cake to a cake turntable using a little buttercream. Add about a cup of buttercream onto the first layer of cake, and smooth using an offset spatula. Create a buttercream dam using the buttercream in the piping bag by piping a ring of frosting around the outside edge of the first layer. Fill in the ring with approximately 1/2 cup of the passionfruit filling. Place the second layer of cake onto the first, pressing very lightly to secure, and sealing the joins with a thin layer of buttercream. Repeat the layering process - add a cup of buttercream, make a dam, fill with 1/2 cup hazelnut filling, then top with the third layer of cake - I like to put this one upside down to ensure that the top of the cake is flat. Return the rest of the buttercream in the piping bag to the bowl with the buttercream.

Crumb coat the cake - to do this, apply a thin layer of buttercream over the surface of the cake, and smooth with a bench scraper or icing smoother. Refrigerate the cake for 30-45 minutes, until the crumb coat has set.

Divide the Remaining buttercream 2/3 to 1/3. Colour the 1/3 portion with gel food colouring to your desired shade.

Create an ombre effect by spreading the bottom 1/3 of the cake with yellow buttercream using an offset spatula, and the top 2/3 with white. Blend the middle section by spreading blobs of white and yellow. Spread buttercream on the top of the cake using an offset spatula.

Smooth the buttercream on the outside of the cake using a bench scraper, scraping down between passes. Fill in any gaps, and add additional colour where needed to give you a nice transition of colour. Continue until you are happy with the finish.

Transfer the remainder of the buttercream (both yellow and white) into a piping bag fitted fitted with a Wilton 1M tip or similar. Pipe blobs onto the top of the cake - using the 1m tip you only need to pipe blobs rather than making a swirl - the tip makes the ruffles for you.

Chill the cake until ready to serve. Remove from the fridge about an hour before serving to bring to room temperature.

Store leftovers in an airtight container in the fridge
