For the countertop:
-heat the oven and proceed to prepare the composition
-whites beat with sugar
-add the yolks one by one, the oil and the flour mixed with cocoa and baking powder
-Put the composition in a tray lined with baking paper / oil + flour
-leave in the oven for 25-30 minutes
For the cream you will also find the instructions on the cream envelope. Basically you need milk and sugar.
Remove the top from the oven, leave it to cool a bit and then put the cream depending on how we like it best. I put the chocolate cream on the counter, then the vanilla one, and at the end the icing.
Leave the cake to cool for 1 hour.
