Ingredients are designed for 2 layers, i.e., for cake 4 cakes need to take only 2 times more. I usually make 4 layers: 2 white, 2 dark, and knead one portion of dough for cakes white, and in the second portion add cocoa powder. Knead the dough on a light cakes. Mix 2 eggs, a can of condensed milk, 1ch.l. soda (repaid), 1 Cup of flour.

Knead the dough on dark cakes. Mix 2 eggs, a can of condensed milk, 1ch.l. soda (repaid), 1 Cup flour, 2 tablespoons cocoa. Instead of cocoa and condensed milk put the can of condensed cocoa.

Divide each portion of dough into 2 parts to make 4 sections of the test: 2 light and 2 dark. Bake in a very hot oven for about 5 minutes. Look at the readiness. Now make the cream, the calculation is the same: 4 layer the ingredients twice. It consists of 2 parts: the custard and cream. Custard: 1 Cup milk (warm), 1 egg, 1 tbsp flour. To brew, intensely whisking to avoid lumps. Cool. Butter: 100 g of softened butter, 0.5 cups sugar, 2 tsp cocoa. Beat until smooth.

Once part of the cream has cooled, they need to connect.

And stir until smooth.

Spread cakes with cream, alternating colors.

It turns out to be cake. Optionally, you can decorate, but he's very beautiful out!
