Making The Sponge Cakes
When making a layer cake always opt for two shallow cake tins rather than one deep one—the reason being that your batter will cook faster and more evenly. Line your pans with greaseproof circles and make sure to oil the pan before you add them in.
Always bake sponge cakes at 175C or 350F. Low and slow is the best approach here because it will make sure of an even bake and help your cake to not rise too much in the middle—something you will have to trim off later.
Cream the butter and sugar with a hand mixer. Then take the eggs and separate the white and yolk. Add in the yolk to your mixture and set the white part for now.
Then add in the flour gently, bit by bit while mixing. Make sure it is sieved.
Now take the egg whites and whip vigorously with the hand mixer until they make soft peaks. Then fold in the egg white mixture yo your cake batter, very gently. This is what will make sure your sponge is light and thoroughly as it gets lots of air into the mix.
Once thoroughly combined, add the nuts, express and divide between the two tins and bake until a skewer inserted into the thickest part comes out clean, about 35 minutes. Test at 30 just to be safe so you don't dry out your cake.
Make The Buttercream
Start by creaming the butter. Then add the icing sugar in small amounts until blended. Make sure to sieve the sugar, so you get no lumps. Once you have created a plain buttercream, slowly add the liquid flavorings, making sure you do not over-beat as the mixture will split.
Build The Cake
Rustic is the name of the game here, so don't panic if your icing skills are the best. Make sure there is a generous amount of buttercream inside the cake, and plenty on top too. You can either place the half walnuts directly onto the top of the cake at intervals, so each piece has one walnut. Although if you are feeling extra fancy, you can pipe buttercream rosettes for them to sit on.
