Ingredients:
125 gr butter
225 gr sugar
3 eggs
1 cup of milk (200 ml)
250 gr flour
1 teaspoon baking powder
1 tablespoon cocoa powder
Preparation:
1. Preheat the oven 180º up and down.
2. In a bowl mix the butter in ointment (somewhat melted) with the sugar.
3. Once it is well mixed add the 3 egg yolks (reserve the whites) and stir with the stick until they are well integrated.
4. Add the milk and stir with the stick.
5. Once everything is well integrated, gradually add the dry ingredients: flour and yeast. Mix everything with the stick until there are no lumps.
6. In another bowl assemble the egg whites to a point of snow with the stick mixer.
7. Once the whites are assembled, gradually add the meringue to the mixture while stirring in an enveloping way with the spatula, until everything is well integrated.
8. Separate the dough into two containers. Put 1/3 of the mixture in a bowl, add a tablespoon of cocoa and stir well.
9. In a mold, previously greased with butter and sprinkled with flour, you make a dough "sandwich". Pour a first layer of white dough, then add all the dough with cocoa and finish covering with the rest of the white dough.
10. Put the already preheated mold in for 50 minutes (without opening the oven door). Then insert a needle into the center of the cake to see if the cake is ready.
