For the mini-nut croissants, knead all ingredients for the dough well together and let rest in the refrigerator for at least 2 hours, but better overnight, wrapped in foil.
Preheat oven to 175 °C top/bottom heat.
For the nut mixture, mix all ingredients.
Cut the dough into quarters, sprinkle some of the nut mixture on the countertop and roll out 1 ball of dough at a time into a round disk of about 26 cm. Turn the dough over as well.
Then cut into 16 pieces and roll into croissants, place them on a baking sheet and bake mini nut croissants for about 12 minutes.
