Marble cake is one of those little wonders that remind me of childhood. My mum used to make this cake quite often and I loved it. At that point I didn’t like chocolate too much, especially the dark one. At the time this was the perfect cake for me with rich vanilla flavour and with chocolate swirls in it. This time I didn’t make my mum’s marble cake, but Pierre Herme’s one, which is a bit denser but equally delicious.
175 g unsalted butter
175 gr sugar
one teaspoon baking powder, a pinch of salt, vanilla
175 g flour
50 g cocoa powder
Preheat the oven at 175C. Separate the egg whites and whisk with a pinch of salt until they reach soft peaks. Mix the egg yolks with the softened butter and sugar for 10 minutes or until tehy get mixed well. Add the flour and the baking powder. Fold in gentely the egg whites (general rule of thumb, do not over mix and only fold in from bottom to the top). Divide the dough in two equal parts. Mix one of the halfs with cacao. Pour the white batter in a baking tray lined with baking paper and then pour the cacao batter on top. Gently create some swirls into the cake with a spoon or a fork.
Bake for 40-50 minutes.
