Rich Chocolate Cake with Chocolate Buttercream

Every cake lover and baking enthusiast needs a decadent chocolate cake recipe in their arsenal and I’m sharing mine today. Tender and soft chocolate layers with a rich chocolate buttercream frosting.

Chocolate cake is one of my all time favourite cake and I enjoy having a slice with some chilled milk.

This recipe is very easy to follow and I even put the measurements in cup measures. However, I show how to properly measure flour with a cup. This involves, spooning the flour into the cup then leveling it. I also used a stand mixer to make this cake but I’ve done it before with an electric hand whisk and also before with a mwiko and it still worked well.

You will also notice that the recipe starts with mixing the cocoa powder with boiling hot water. The hot water blooms the cocoa powder yielding the chocolate taste that we all love. I also added some instant coffee to give the chocolate flavour some kick.

The beautiful thing about this rich chocolate cake recipe, it can be adapted to get different variants. Addition of orange zest to the mix gives you chocolate orange, perhaps some peppermint essence for a chocolate mint or even some peanut butter to get a chocolate peanut butter cake. As you can see, limitless options.

The recipe yields about a kilo of cake and thus the ideal cake tin size to use is either a 7 inch round tin or 8 inch tin, use three tins for the former and two for the latter.

For the frosting, I used chocolate buttercream, however dark chocolate ganache can work too.

And that’s how you make a rich chocolate cake.
