Melt the coconut oil in the microwave. Mix with 1 teaspoon of sugar or erythritol and 1 tablespoon of baking cocoa. Mix the quark with the rest of the erythritol and some desiccated coconut.
When everything is well mixed, fold a few more coconut flakes into the liquid chocolate and stir again. Then pour the liquid coconut chocolate over the quark and put everything in the fridge for about 30 minutes.
