Chocolate cakes with Baileys cream

Delicate chocolate cakes with oil-custard cream Baileys. The biscuit
recipe is Irish, with the addition of dark beer (such as Guinness®)
and sour cream. Biscuit is soft and slightly moist with a pleasant
aroma. Beer is brought to a boil, so the alcohol content in the final
product is negligible. A very delicate cream, which is convenient to
decorate, keeps the shape well.

200 g of butter
3/4 cup cocoa powder (without sugar)
2 cups of flour
2 cups of sugar
3/4 tsp soda
1/2 tsp. salt

cooled egg mixture, whilst continuing to beat. At the end, add bailys
and cocoa powder and whisk again to light lush mass. The cream should
be beaten for about 15 minutes in total to get the right consistency.

with a nozzle (you can use a clean plastic bag for this purpose - cut
off the tip and insert the nozzle tightly from inside). Nozzle - with
denticles. Squeeze in a circle, finish in the center.
