Cocoa roll with quark filling

INGREDIENTS
- 4 eggs
 - 5 tbsp xylitol
 - 3 tbsp cocoa powder
 - 2 tbsp whole grain spelt flour
 - 1 tsp baking powder
 - 2 bananas
 - pinch of salt
 - 500 g semi-fat spreadable quark
 - 100 g low-fat cream cheese
 - 20 g grated coconut
 - 1 tbsp vanilla paste
 - 70 g xylitol
 - 10 g clear gelatin
 - 50 g dark chocolate
 - 1 tsp coconut oil
 - 10 g grated coconut
 
METHOD
- First, separate the egg yolks from the whites.
 - Beat the egg whites with a pinch of salt until stiff peaks form.
 - Carefully fold in all the remaining ingredients for the batter, including the yolks.
 - Pour the batter onto a large baking sheet lined with parchment paper and spread it evenly with a spoon or spatula.
 - Bake the batter for 12 minutes at 175°C (top and bottom heat setting).
 - In the meantime, mix all the filling ingredients together. If you want the filling to set nicely, I recommend adding 10 g of clear gelatin.
 - While the cake is still warm, roll it lengthwise along with the parchment paper.
 - Let the cake cool, then unroll it and spread the prepared filling over the entire surface.
 - Place two peeled bananas along the edge of the longer side.
 - Carefully roll the cake lengthwise.
 - Break the chocolate into a small bowl, add a teaspoon of coconut oil, and melt it in the microwave (or over a double boiler).
 - Pour the melted chocolate over the top of the roll, sprinkle with coconut, and let it set in the fridge for at least an hour.
 - After an hour in the fridge, slice the roll into pieces and serve.
