The Most Epic Triple Chocolate Cake

This triple chocolate cake is basically every chocoholic’s dream come true. It’s moist, flavourful and intensely chocolatey, as well as drop dead gorgeous. To make it even more amazing, there are three different cake sponges AND three different chocolate frostings (white, milk and dark) to create an ombre effect both on the outside and the inside of the cake.

This post has been created in collaboration with Tala. All opinions expressed in the post are my own… plus, there’s a whole lotta cake – so read on. (For more information you can check out my Disclosure Policy.)

I’m pretty sure we can all agree that cakes have a special magic about them. Now, don’t get me wrong – cupcakes, brownies and cookies are delicious and wonderful… but bake a cake, and you will stop people in their tracks and put a smile on their faces.

So today, I’m hoping to make you smile (and drool… and lick your screen) with this EPIC triple chocolate cake.

From its ombre chocolate buttercream frosting to the glossy chocolate ganache drip (and don’t even get me started on the decadence that are the chocolate truffles sitting on top of swirls of luscious chocolate buttercream), this cake is a real showstopper… and it’s just in time to celebrate the return of The Great British Bake Off!

If you’ve been round these parts before, then you know I’m obsessed with baking, chocolate and kitchenware, so it’s been a real treat to team up with Tala to bring you this delicious cake recipe.

It’s slightly more involved than my usual cake recipes – after all, instead of a single type of sponge cake and a single buttercream frosting… we have triple that. But don’t worry, the individual steps to making this cake are actually dead simple.

Making the sponges requires nothing more than mixing a few things together, and the trio of chocolate buttercreams has the same base of plain American buttercream, with different melted chocolates added to create the different flavours and colours.

And most importantly, when you end up with a cake that tastes incredible and looks this good – all the effort is 100% worth it. Promise.

7 reasons for why you should make this triple chocolate cake ASAP

1. CHOCOLATE – And lots of it. There may or may not be over a kilo of chocolate in this cake AND it’s not just one variety of chocolate. Nope, it’s more like 5 different types of chocolate. Or maybe 6… I honestly lost count. Suffice it to say, this cake is every chocoholic’s dream come true. You’re welcome.

2. The moist and decadent chocolate cake sponges – To create an ombre effect not only with the frosting but also on the inside of the cake, we have a trio of sponges: white, milk and dark chocolate. They are all incredibly flavourful, moist and fluffy, and having three different sponges makes the eating experience so much more exciting.

You’ll notice that the dark chocolate sponge recipe is a bit different from my Ultimate Gluten Free Chocolate Cake, mainly because it contains a whole lotta melted chocolate (as opposed to only cocoa powder). That makes the chocolate flavour much more intense, and the cake sponges basically taste like brownies… if brownies were fluffy and moist, instead of fudgy and gooey.

In one word, the chocolate cake sponges are AMAZING.

3. The luxurious, velvety chocolate frosting – To create the ombre effect, we again have a trio of chocolates: white, milk and dark chocolate. The frosting isn’t too sweet, but allows the chocolate flavour to really shine through in all its wonderful glory.

4. And the decadent chocolate decorations – Because we’re going for that WOW effect (and because I’ll take any excuse to add more chocolate to a dessert), the decorations include a glossy chocolate ganache drip, piped swirls of multi-coloured chocolate buttercream, chocolate truffles and chocolate shavings.

5. Can you say DROP DEAD GORGEOUS??? – I mean, just look at it!

6. It’s gluten free! – That’s right, this beauty of a cake is gluten free! Of course, if that’s not a requirement for you, you can make it with regular plain all-purpose flour (use the same amount as for the gluten free flour by weight), and omit the xanthan gum in that case.

7. Chocolate. – Because it deserves saying twice (or, you know, a bazillion times in the case of this cake and this post).

How do you make triple chocolate cake?

To avoid being super repetitive, I’ll just walk you through how to make the dark chocolate cake sponge – making the other two sponges follows all the same steps, with the ingredient quantities adjusted slightly, to account for the difference in sweetness, fat content and cocoa content between the different types of chocolate.

(For the full recipe, including the ingredient quantities, scroll down to the bottom of the page.)

First, we’ll melt some dark chocolate (70%+ cocoa content) and butter together. At this point, let’s take a moment to appreciate just how gorgeous the bowl from Tala’s new Indigo and Ivory range is. So. Pretty.

Next up, we’ll add the sugar and eggs, and mix well – bonus points if you use a dry measure as beautiful as the one from Tala’s Indigo and Ivory range.

Then, we’ll sift in the dry ingredients (plain gluten free flour blend, almond flour, cocoa powder, baking powder, salt), and whisk until evenly combined.

Also, how pretty is Tala’s Indigo and Ivory flour sifter?!

Next, we’ll add in hot water and milk, and whisk well until we get a smooth cake batter. (Depending on the coarseness of your almond flour, the cake batter might look a bit grainy, but that’s perfectly okay.)

Finally, we’ll transfer the cake batter into a lined cake tin – and bake! Here, I’ve used Tala’s Performance Bakeware 20 cm (8 inch) springform pan, and it baked the sponges perfectly.

How long do you bake chocolate cake sponges?

Because these are 8 inch (20 cm) cake sponges of quite significant thickness (plus, there’s an enormous amount of chocolate in each one), they do take a while to bake: about 55 minutes at 355 ºF (180 ºC).

If you use a different size of baking tin or adjust the ingredient quantities, the baking time will change (but keep the oven temperature constant at 355 ºF/180ºC). To test when the cakes are done, insert a toothpick/skewer into the middle of the sponges – when it comes out clean or with a few moist crumbs attached, the cakes are baked perfectly.

How do you make chocolate buttercream frosting?

All three buttercream frostings for this triple chocolate cake have a common base, which is your typical American buttercream made from butter, powdered/icing sugar, a dash of vanilla and a pinch of salt.

Because I don’t like my frosting too sweet, I’ve used a smaller amount of powdered sugar than you’d find in many other recipes, but you can definitely adjust that to your personal taste.

Then, to create the different chocolate frostings, you just add melted chocolate and/or cocoa powder to that American buttercream.

  • For the white chocolate frosting, you need to add melted (and slightly cooled) white chocolate.
  • For the milk chocolate frosting, you need to add melted (and slightly cooled) milk chocolate and a bit of cocoa powder.
  • For the dark chocolate frosting, you need to add melted (and slightly cooled) dark chocolate and a whole lotta cocoa powder.

That’s it – as promised, it really couldn’t be easier.

Assembling this chocolate-filled dessert is a piece of cake (pun 100% intended) – you just have to layer together the sponges and the buttercream, frost the outside, add the chocolate ganache drip and decorate the top.

That said, try to not do that in the middle of a heatwave, when temperatures are reaching 32 ºC (87 ºF). Chocolate, buttercream and heat don’t mix all that well… just saying. (And I’m speaking from horrible, horrible experience here.)

Unless, of course, you want to recreate the stressful conditions of the Bake Off tent – in that case, go right ahead.

That’s it, friends. The most luxurious, decadent triple chocolate cake… it’s the stuff dreams are made of. I hope you love it as much as I do (which is oh-so much, to the moon and back).

Enjoy.

Instructions

For ALL chocolate sponges (note the different ingredients/quantities for the different sponges):

  1. Pre-heat the oven to 355ºF (180 ºC) and line three 8 inch (20 cm) cake pans with baking/greaseproof paper.

  2. In a heat-proof bowl above a pot of simmering water, melt together the chocolate and butter.

    NOTE: For best results, melt the white chocolate and butter separately for the white chocolate sponge, then mix them together when you start adding the other ingredients.

  3. Add the sugar and eggs, and whisk well.

  4. Sift together the dry ingredients (gluten free flour blend, almond flour, xanthan gum, baking powder, salt and cocoa powder for dark chocolate sponge) and add them to the chocolate mixture. Mix well until evenly distributed.

  5. Add the milk and hot water, and mix well until you get a smooth cake batter.

  6. Transfer the cake batter into the lined cake pan, and bake at 355 ºF (180 ºC) for about 55 minutes, or until risen and an inserted toothpick comes out clean or a few moist crumbs attached.

  7. Allow to cool in the cake pan for about 10 minutes, then remove from the cake pan and allow to cool fully on a wire cooling rack.

For chocolate buttercream:

  1. In a stand mixer using a paddle attachment or using a hand mixer with the double beater attachments, beat the butter for 2 - 3 minutes, until pale and fluffy.

  2. Add the powdered sugar, and beat for a further 5 - 7 minutes.

  3. Adjust the sweetness if needed (by adding more powdered sugar), and add the vanilla paste and salt.

  4. Divide the buttercream into three equal parts.

  5. For dark chocolate buttercream: Add the melted dark chocolate and 1/4 cup cocoa powder into one third of the buttercream and mix well until combined.

  6. For milk chocolate buttercream: Add the melted milk chocolate and 1 - 2 tbsp cocoa powder into one third of the buttercream and mix well until combined.

  7. For white chocolate buttercream: Add the melted white chocolate into one third of the buttercream and mix well until combined.

Assembling the triple chocolate cake - Part I:

  1. If the sponges are domed, level out the tops with a serrated knife.

  2. Layer sponges and buttercream together in the following order (bottom to top): dark chocolate sponge, dark chocolate buttercream, milk chocolate sponge, milk chocolate buttercream, white chocolate sponge, white chocolate buttercream.

  3. Pipe rings of chocolate buttercream around the cake, piping the dark chocolate buttercream at the bottom, milk chocolate buttercream in the middle and white chocolate buttercream at the top. Smooth out the frosting, creating the ombre effect. Chill the cake for at least 30 minutes in the fridge, or until the frosting has firmed up.

For chocolate ganache drip:

  1. While the frosted cake is chilling, place the chopped dark chocolate into a heat-proof bowl. Heat the double/heavy cream until only just boiling (either on the stove or in the microwave), then pour it over the chocolate.

  2. Allow to stand for 2 - 3 minutes, then stir well until you get a smooth glossy ganache.

  3. Set aside and allow to cool slightly.

Assembling the triple chocolate cake - Part II:

  1. Once the cake is chilled and the frosting feels firm to the touch, decorate the cake – first with the chocolate ganache drip.

    Check the consistency of the chocolate ganache. It should be runny enough to drip, but not too hot (otherwise it will melt the buttercream). If it's too thick, heat it up briefly in the microwave.

    For the easiest (and prettiest) drip, transfer the chocolate ganache into a squeeze bottle.

    Create the chocolate drip: first allow the chocolate ganache to gently run down the sides, then fill out the top of the cake by drizzling on more ganache and smoothing it out with an offset spatula.

  2. Allow the ganache to firm up slightly (this should only take a few minutes because of the cold cake), then decorate the top of the cake.

    You can follow my example and decorate the cake with piped swirls of buttercream, chocolate truffles and chocolate shavings, or get creative and dream up your own design.

  3. Enjoy!

Storage:

  1. The cake keeps well in a closed container or wrapped in cling film, in a cool dry place or in the fridge for 3 - 4 days.

    (If you keep the cake in the fridge, cut the desired number of slices and allow them to come to room temperature for about 10 - 15 minutes before serving.)
