Marmorkuchen (marble cake) with milk:
Ok the first try wasn´t that pretty but yesterday I got it right. It´s really obvious for me that there is a coincidence that spring started with my two cakes I backed. The biggest mistakes on cake one was too less buttering of the form and not breadcrumbed. I enhanced the recipe a bit due to the size of the cake form:
250g butter
250g sugar
250g flour
4 eggs
3 spoons of real cacao powder for the other half of the dough
1 brief of vanilla sugar
a bit of salt
a bit of baking powder
a bit of rum
50 minutes on 180 Celsius, thats it! Best served with fresh cooled milk from a farm.
be-cause - style, travel, collecting and food blog 
I have to try adding rum to my next marble cake
it was not in an official recipe but it add´s well, esp. if you add a honest not to much flavoured
rum like flor de cana 12 years old (which is a pity) in it.
