We take bitter chocolate pieces and fill it with hot milk + instant coffee, mix everything and cool.
Separately, beat (with a whisk) soft butter + sugar + vanilla sugar + egg.
We combine the two mixtures, mix with a whisk and add the sifted flour with baking powder.
Bake at 180 degrees until dry. Let cool on a wire rack. We cut off the cap of the cupcakes so that there is a flat surface, put it on a dish cut down and cover with chocolate icing.
I covered it with chocolate ganache. For him, we take dark chocolate (pieces) and pour it with hot 30% cream and add butter. Mix everything well, let cool slightly and cover the cupcakes. Enjoy your meal!
