CHOCOLATE & SALTED CARAMEL LAYER CAKE

It’s exactly a month ago that I made this celebration cake for my brother’s birthday. Yes, it’s taken that long for me to get around to posting it – what with all the Christmas baking and cooking over the last month, I just haven’t had a chance till now.

So, without further ado, let me introduce this Chocolate & Salted Caramel Layer Cake – undoubtedly the most decadent cake I’ve made so far. With its layers of moist, dark chocolate sponge, thick salted caramel filling and lashings of lighter-than-air salted caramel Swiss meringue butter cream, it’s a hedonist’s fantasy.

The brother, in whose honour I made the cake, looked like he’d died and gone to Heaven when he clapped eyes on it. And, I have to say, it really looked the part even before we cut into it, with its shiny dark chocolate pearls, butter cream rosettes and Lindt chocolate balls. And, then to find the layers of salted caramel inside, well… nirvana.

I borrowed from a couple of recipes in order to make this show-stopper cake. The chocolate cake and caramel recipes came from Bakers Corner.co.nz, and the salted caramel Swiss meringue buttercream recipe from New Zealand Weddings.co.nz. As it turns out, a killer combo.

I went with Italian flour again on this occasion, given my family and I can tolerate it really well. However, if you are gluten-free, simply swap the standard flour for gluten-free flour – it will be just as good.

A couple of (tiny) things I’d do differently if I made this again; I’d pipe 12 smaller rosettes on top of the cake so that each slice of cake gets a rosette and chocolate ball. I only did 8 and, yes, there were fights over who scored the Lindt chocolates! And, I wouldn’t bother piping a butter cream ring on top of each cake layer, which I did to prevent the caramel spilling down the sides. As it turned out, I needn’t have bothered as the caramel was nice and thick and set quickly in the fridge anyway.

If you’re looking for a cake worthy of a celebration event, this one definitely fits the bill – my entire family can attest to that!

Equipment

  • 1 Stand mixer

Ingredients
  

For the cakes:

  • 1-1/2 cups plain flour (sifted)
  • 1-1/2 cups caster sugar
  • 1-1/2 cups dark cocoa (sifted)
  • 2 tsp bicarbonate of soda (baking soda)
  • 1 tsp baking powder
  • 2 eggs
  • 3/4 cup buttermilk (I made my own by adding a tablespoon of lemon juice to plain milk and stirring to combine)
  • 3/4 cup warm water
  • 1/4 cup vegetable oil
  • 2 tsp vanilla bean paste or vanilla essence

For the salted caramel*

  • 2 cups caster (superfine sugar)
  • 2 tbsp glucose (or corn syrup)
  • 1/2 cup water
  • 1 cup double cream
  • 4 tsp sea salt
  • 4.9 oz cold butter (chopped)

For the salted caramel Swiss meringue buttercream**

  • 7 oz egg whites
  • 8.8 oz caster (superfine sugar)
  • 15.8 oz butter (diced and at room temp)
  • 1/2 cup salted caramel (recipe above, or to taste)
  • 1 tbsp vanilla extract

Instructions
 

For the cakes:

  • Preheat oven to 180°C (360°F).
  • Grease and line base and sides of two 20cm (8 inch) round cake pans with baking paper. Combine flour, sugar, cocoa, baking soda and baking powder in the bowl of an electric mixer and beat on low until just combined.
  • Add eggs, buttermilk, warm water, oil and vanilla bean; beat on a low speed until well combined.
  • Divide batter between pans and bake for 45 minutes or until an inserted skewer comes out clean. Cool cake in pans for 20 minutes. turn out on a wire rack and cool completely.

For the salted caramel:

  • Combine sugar, glucose and water in a medium saucepan over high heat. Cook, without stirring, for 15 minutes or until sugar is golden.
  • Remove from heat and carefully pour in cream (be careful as the caramel mixture will bubble up), whisk until smooth (if it seizes, simply return to the heat and stir until smooth). Add in the butter and salt and stir to combine.
  • Divide caramel into two equal amounts in separate bowls (one portion will be for spreading on the cakes, and the other for adding to the buttercream) and leave to cool completely. Pop into the fridge if you’re making it ahead – just be aware that it will thicken and firm up when chilled. When you need to use it, just take it out of the fridge to soften (a few seconds in the microwave will help if you’re in a hurry).

For the salted caramel Swiss meringue buttercream:

  • Combine egg whites and sugar in a heat proof bowl over a pan of simmering hot water.
  • Whisk continually until mixture becomes warm to touch and sugar has dissolved.
  • Pour mixture into bowl of stand mixer and whisk on high until stiff peaks form and the mixture has cooled (just feel the bowl – it should no longer feel warm to the touch).
  • Once the mixture has cooled (and not before!), switch to a paddle attachment and start adding the butter piece by piece with the mixer on med-high speed (don’t worry if the mixture looks soupy or curdled – it will all come together with enough mixing). Once all the butter is added, keep beating until the mixture becomes silky and shiny.
  • Stop the mixer, scrape down the sides, and add the vanilla and 1/2 cup salted caramel (from one of the two portions of caramel). Beat on medium speed until combined. Taste the mixture and add more salted caramel if you prefer.
  • Refrigerate the buttercream if you want the mixture to be a little firmer before spreading over the cake, or if you have made it ahead of time.

To assemble:

  • Trim tops of cakes using a serrated knife to create a level surface, and cut each cake in half horizontally to create a total of 4 layers.
  • Transfer 1 layer to a serving platter. Using the second portion of salted caramel, spread 1/3 of caramel over top of the cake layer (if you think the caramel might spread, simply pipe a ring of butter cream around the outside to contain it as I did). Top with the second cake layer, then 1/3 more caramel. Put the third cake layer over top and spread with the remaining 1/3 caramel. Finally, put the fourth cake layer over top, leaving it uncovered.
  • Refrigerate the cake for 30-60 minutes or until the caramel is set.
  • Once set, add the buttercream to the top and sides of the cake and decorate as you prefer.
  • Store the cake in the fridge if you’ve made it ahead of time and take it out about 15-30 minutes before serving (depending on humidity and temperature).

Notes

*This is a double batch of salted caramel; half of which is used to spread on the cakes and, from the remaining half, a half cup added to the Swiss meringue buttercream.
**This recipe makes a generous amount of buttercream, easily enough to frost the cake and pipe some decorations on top. Should you want to spread buttercream on each layer (on top of the caramel), there’d probably be enough for that too.

  1. Not sure if you received my first message but thank you for sharing this fabulous recipe! It was delicious and I was pleasantly surprised after taking my first bite on how well the flavors blended and that it wasn’t too sweet. The caramel and frosting seemed very sweet to me but the dark cocoa cake balanced it out perfectly! I added the blackberries as decor and flavor to allow for some sourness to also balance out the sweet. Thank you again, it was a real hit!!
