Mix walnuts, buckwheat, dates, syrup, vanilla pod, 1 pinch of salt and approx. 1 tbsp. water in a food processor or in a blender with an S-knife (specially curved knife that optimally draws in the ingredients) to form a homogenous mass.
Pour into a bowl. Knead cocoa powder and coconut flour well.
Squeeze the mixture into mini-ball moulds made of silicone and chill for about 2 hours. Carefully press out of the mould. Keep the mixture in a cool place.
Tip: More digestible and durable: Kerstin soaks walnuts in cold water for about 4 hours. Then they are poured off and rinsed cold. Drained nuts are left to dry at 42 °C for about 24 hours.
