What is Mocha?

Essentially, Mocha is a type of good quality coffee made from a special coffee bean. Mocha coffee is often interpreted differently worldwide, but the basis is a good espresso, followed by milk and some chocolate syrup. You can also see it as a sweet, nutty and chocolatey variant of a latte. Mocha represents the combination of coffee and chocolate or the flavour of coffee and chocolate, which makes the amazing flavour profile of this cake. 

A ‘Mokkataart’ is a cake typically served at dutch birthday parties, where I’ve had my first encounters with this amazing taste! 

How do I make this Chocolate Mocha Cake?

There are quite a few components to this recipe, so read the instructions carefully. But essentially you start of with a basic fluffy vanilla cake, which you drench in a coffee simple syrup. You then want to fill and stack your cake using the ganache and buttercream, then finish of your cake with more buttercream, the nougatine and decorate it with whipped cream

Tips for making Mocha Cake

Use good quality coffee - Don’t skip this!! Coffee is one of the main flavours of this cake, so you don’t want to opt for a cheap canteen version. Invest in that good cup of espresso

Add vanilla & salt - Even though this cake has quite outspoken flavours, don’t skip the vanilla & salt to balance out the strong flavours and deepen their intensity. 

Don’t overbake your cake - This cake recipe is very light and fluffy, but therefore also easier to dry out as it doesn’t use any butter. So be sure to not overbake it. Also be careful not to under-bake, as the cake might then collapse

How do I store Chocolate Hazelnut Mocha Cake?

You can store this cake in your fridge for up to 4 days, but I can’t believe that it’ll last that long! 

Enjoy loves! xx

Instructions

Vanilla Cake

  1. Using a standing mixer, start off by whipping your eggs, sugar and vanilla until fluffy and doubled in size, about 15-20 minutes
  2. Sift in the flour, cornstarch and salt. Fold this in using a spatula while trying to maintain as much air as possible
  3. Pour the batter into a prepared pan and bake for 35-40 minutes or until a toothpick comes out with a few crumbs
  4. Leave the cake to cool completely before decorating

Coffee simple syrup

  1. Mix your sugar, coffee and water into a saucepan and stir over medium heat until the sugar is dissolved
  2. Set the syrup aside to cool down

Nougatine

  1. Add the water & sugar to a pan and heat over medium heat until caramel forms
  2. Pour the caramel over the hazelnuts and let this cool completely
  3. Once cooled, break the caramel hazelnuts into chunks and add them to a food processor or a cutting board. Roughly chop the caramel and hazelnut by pulsing the food processor or chopping it by hand
  4. Add the chopped nuts to a frying pan and roast over medium heat until the hazelnut starts to cluster
  5. Set aside until needed 

Mocha buttercream

  1. Whip your butter until pale and fluffy using a stand mixer fitter with the butterfly attachment, for about 8-10 minutes. Scrape down the sides of the bowl if necessary
  2. Add the powdered sugar, salt & vanilla and beat until combined
  3. Add your pastry cream and mix the buttercream using the lowest speed until fully incorporated
  4. Lastly, add your espresso and keep mixing until it is fully incorporated
  5. If you want all the air bubbles to be gone from your buttercream, keep mixing on the lowest speed for about 15 minutes and you’ll have a silky smooth buttercream

Chocolate ganache

  1. Heat your cream over medium heat and pour this over your chocolate, leave this to melt for a minute. Add your liquor at this stage if you’re using this
  2. Then mix until smooth

Assembly

  1. Slice your cake into layers and drench each layer with coffee simple syrup
  2. Add a thin layer of buttercream on your bottom cake layer and pipe a dam around the edges
  3. Pour in your chocolate ganache and close off the layer with more buttercream
  4. Repeat this process until you have reached your final cake layer
  5. Top your cake with the last layer of cake and cover the cake entirely with the buttercream
  6. Coat the edge of the cake with the nougatine
  7. Decorate your cake using whipped cream and mocha chocolate beans and enjoy!
