06 - Pinch off walnut-sized portions of dough. Roll into smooth balls, dip in melted butter or coconut oil, then coat thoroughly in cinnamon mixture.
07 - Place coated dough balls in prepared pan, stacking in layers. Leave slight space between pieces for rising during baking.
08 - Bake for 25–30 minutes until golden brown on top and firm to the touch. A toothpick inserted should come out clean.
