Hazelnut Coffee Chocolate Cake

img_5600For this cake I used Yo’s Ultimate Chocolate Cake recipe because I love her and her YouTube channel, and after making the cake for the first time a few weeks ago I realised my life was changed! It’s moist, rich and just delicious!

Other than knowing what cake recipe I’d be using, I didn’t actually plan what filling to use or how to decorate the cake before starting it. It was only last minute that I decided to add the flavour of coffee by adding instant coffee to the cake batter and the icing. I then sprinkled crushed Kinder Buenos in the middle to add a hazel nutty flavour.

I had wanted to make a ganache to pour over but ran out of time as this was part of my GBBO Showstopper Challenge. Maybe next time.

img_5480First I creamed together the butter and sugar till pale, whipped and fluffy.

img_5486img_5489To a heatproof bowl, I added the cocoa powder, instant coffee and boiling water and carefully whisked till smooth. I let this cool whilst the butter and sugar was whipping.

img_5490I mixed the plain flour, bicarb, baking powder and salt together in a separate bowl.

img_5492I added the eggs to the butter and sugar, 2 at a time and mixed to combine completety. I then alternated adding the dry ingredients, the cocoa liquid and the other eggs and so on until all the ingredients were used up it formed a rich dark brown cake batter.

I evenly divided this between 2 lined 9″ cake tins and baked at 180°C for 35 minutes till a skewer came out out clean from the centre. I left this to cool completely.

img_5557For the icing I beat the softened butter till light and whippy.

I beat in the icing sugar, cocoa powder, instant coffee, and melted chocolate till smooth.

img_5576To construct, I levelled the tops off each cake. I then spread the icing on top of one cake, sprinkled on crushed Kinder Buenos, the placed the second cake on top. I piped on some more icing, then topped with chocolate coated coffee beans.
