Mix all ingredients until you end up with a fairly smooth dough.
Grab your donut pan and press a little bit of dough into every shape to cover the bottom. Take your cookie butter cups out of the fridge and press 3 into each donut shape. Then take the remaining dough and cover the cookie butter cups.
Transfer to the freezer to set for at least 3 hours or overnight.
To release the donuts from the pan, tap the pan slightly on the kitchen bench. Or even turn it around and tap it on the kitchen bench again.
Once released, coat them with melted chocolate and chopped nuts or cookie crumbles.
