    If like me you love chocolate then you will love this mini 6 inch double chocolate cake recipe. The soft, moist chocolate cake is covered in a chocolate buttercream and decorated with simple sprinkles.

    6 inch chocolate cake

    This 6 inch chocolate cake is made using good quality cocoa powder which gives the cake the most amazing flavour. The cake is prepared using two 6 inch pans which makes a mini cake. I’m all for 6 inch mini cakes as they are perfect for times when you feel like some cake but don’t want to use up lots of ingredients to make a large cake.

    Also with 6 inch cakes, you do not have lots of leftover cake as it tends to all be eaten with 2 days. Usually, when I make a large chocolate cake, my family spend the first 2 days eating lots of it then by day 3 they can’t stand to look at it so this size cake is perfect to prevent that.

    You can serve this cake as an after-dinner dessert or with your afternoon cup of tea which is what I do when I come home from the school run. This recipe is very quick and one of the easiest recipes to prepare so if you love chocolate then you will love this mini double chocolate cake.

    How to Make Double Chocolate 6 Inch Cake

    Make the Cake

    1. Line two 6 inch cake tins and preheat the oven to gas mark 4/350oF/180oC/160oC fan. To a bowl, add and combine the self-raising flour, cocoa powder, bicarbonate soda and salt then set the bowl aside.

    2. To another bowl, add the eggs and sugar then whisk them together. To the same bowl, add the buttermilk, vanilla extract and vegetable oil then whisk them together. Gradually mix in the dry ingredients until you get a smooth chocolatey batter that resembles melted chocolate.

    3. Divide the chocolate batter between the 2 baking tins and bake for 30 minutes. Once baked, allow the cakes to cool in their tins for 15 minutes then remove the cakes from the tins and allow them to completely cool on a wire rack.

    Make the Chocolate Buttercream

    4. To a bowl, add and combine the icing sugar and cocoa powder. To a stand mixer bowl, add the butter and mix the butter using the paddle attachment. Pour in ½ the mixed icing sugar and cocoa powder and continue to mix on a medium setting. Once combined, add in the second half of the icing sugar and cocoa powder and continue to mix. Add the vanilla extract and whole milk and continue to mix until the buttercream is smooth with no lumps.

    5. Level your cakes if necessary then place a cake board on a turntable and place one cake on top of the board. Add some buttercream and using a palette knife smooth it evenly on top of the cake. Place the second cake on top of the buttercream and the cover the cakes with the remaining buttercream. Decorate with sprinkles if using.

    Recipe Tips

    • Use good quality cocoa and not drinking chocolate. I use Green & Black's Cocoa for any recipe that requires cocoa powder. I have been using it for years and it honestly has the best flavour.
    • Level your cakes before frosting them if they have a dome on top. You can level them using a serrated knife or a cake leveller.
