Croque Monsieur, yes please! This warm and cheesy sandwich is an absolute banger.
Combine the flour, protein powder, baking powder and half of the cocoa powder in a bowl and make a well in the centre. Add the egg, egg white and 70g of the yoghurt and whisk to create a smooth batter.
Melt the oil in a non-stick frying pan then fry large spoonfuls of the batter for a minute on each side until puffed up and golden.
Layer the pancakes with the remaining yoghurt and the sliced banana then dust with the remaining cocoa powder.
