Mix all dry ingredients together. Then add the liquid ingredients and stir well.
Spread a dollop of chocolate dough in a 12-cup muffin pan so that the base is covered a good 1-2 cm. Then put a few berries and a piece of chocolate (you can also chop it up if you want) in each mold and pour the remaining chocolate batter over it.
Bake in the oven preheated to 180 ° C for about 25 minutes.
