One should not make them in the oven, but they must be kept cold.
I think most people in Sweden know these chocolate balls....;)
Chocolate Balls150 ml rolled oats
100 ml rye flakes (looks just like rolled oats, only rye)
50 ml sugar
50 ml cocoa powder
pinch of salt
1 tbsp vanilla sugar (or 1 tsp vanilla extract)
2 tbsp hot, strong coffee
50 g unsalted butter
pearl sugar or coconut flakes
Mix oatmeal, rye, sugar, cocoa, vanilla sugar (or extract) and a pinch of salt.
Cut the butter into cubes and add them to the bowl.
Pour in the coffee.
Work with your hands, and mix until you have a uniform, thick dough.
Shape small balls, about the size of a walnut, and roll them in your chosen decoration.
Place in the fridge for a little while before you eat - they'll firm up and they're much better that way.
Hope you enjoy them!
