The recipe for the cup cake was seen on foreign websites. I changed the cocoa powder to dark chocolate and added rum. The sugar of the square itself is 150g, but when I do it myself, it seems to be half-discharged. This is a personal taste.
Butter at room temperature softened and sugared
Add eggs repeatedly and mix evenly
Add the dark chocolate melted in water and stir evenly
Sift through low-gluten flour, baking powder, add vanilla extract, salt and rum, and mix well.
Pour into the mold and preheat the oven for 180 to 25 minutes.
Add the cream to the sugar, decorate it on the cooled cake, and sprinkle with chocolate crumbs and other decorations.
