Chocolate cupcake

I've never been in the States, but I definitely like cupcakes, so I just had to try to make them. I found a lovely recipe for the cake here.

Ingredients (for 12 cupcakes):

butter (120 gr)
cocoa (2 tablespoons)
chocolate (80 gr)
flour (120 gr)
baking powder (1 teaspoon)
egg (2)
sugar (120 gr)
chocolate cream for cakes powder
milk
colourful sugar bits

Mix butter with sugar, add the eggs and mix in a smooth paste. In the meantime melt the chocolate, when it is cool add to the mixture. At the end add flour, baking powder and cocoa powder. Mix in a smooth paste. Put it in 12 cupcake papers and bake for 20 minutes in a preheated oven on 170° Celsius. When they're cool, do the cream with a chocolate cream powder for cakes and milk. Put it on the top and add some colourful sugar bits. Does it look good?
