Mokkapalat, coffee brownies Finnish-style

These are the brownies that most Finns know ever since their mum made them (or at least those of my generation ;) : Mokkapalat! The bottom is very airy and the topping is wonderful containing real coffee.

Ingredients (quantities for a small oven):

-for the bottom:
3,3 dl wheat flour
3 eggs
2 dl sugar
1,3 dl milk
130 g butter or margarine
2 tablespoons cocoa powder
2 teaspoons baking powder
1,3 teaspoon vanilla sugar

-for the topping:
2/3 package icing sugar
30 g butter or margarine
3-4 tablespoons coffee
1 tablespoon cacao powder
2 teaspoons vanilline sugar

Preparation:
Melt the butter meant for the bottom of the cake. Let it cool down for a while. Add the eggs and the sugar into a bowl and mix them with a mixer until they will have obtained a foamy composition. Take another bowl where you mix the rest of the dry ingredients together.

Take turns mixing gradually the milk and the dry ingredients to the egg-sugar foam. When you are done, mix the previously melted margarine into the foam.

Add baking paper on an oven plate and pour the foam on the oven plate evenly. Bake it on 200'c for around 15 minutes.

Melt the butter or margarine meant for the topping. Mix all the other ingredients together. At the end add the melted butter and mix. Spread the topping all over the cake, and don't be too slow or make pauses, because the topping is likely to become stiff soon.

If you like, decorate the cake with sprinkles.
