Form approx. 12 walnut-sized balls from the dough and chill. For the crumbles, put 75 g margarine with 1 tbsp. sugar, 125 g flour and 1 pinch of salt in a bowl. Knead into crumbles with your hands.
Briefly mix in the peanut bar, set aside.
For the dough carrots, clean, peel and finely grate. Sieve 350 g flour with baking powder into a bowl. Add 200 g sugar. Add oil and oat drink while stirring. Fold in carrots briefly. Halve the dough.
Stir in half the cocoa and 50 g of chocolate. Line a muffin tray (12 trays) with paper cups. Spread the light pastry first, then the dark pastry. Put dough balls in the middle and spread crumbles on top.
