For the chocolate topping, the butter should be very soft. It is best to put it out of the refrigerator the day before.
Mix the butter with the cream cheese and the cocoa powder (instead of cocoa powder you can also use 200 g dark chocolate).
Then gradually add the powdered sugar – it is best to sift it into the mixture. The topping should now be placed in the refrigerator for 2-3 hours and then piped onto the muffins.
It is best to use a piping bag with a star-shaped nozzle. Now you can decorate the chocolate cupcakes as desired with glitter, chocolate shavings, or like me with an edible pearl.
