Place the oat flour and coconut in a bowl, add a pinch of vanilla and the baking powder, and mix. Add half an egg and mix well until a dough forms.

Set the dough aside to rest briefly so the flour absorbs the egg. After 10 minutes, shape it into a finger-like form—or any shape you prefer—and top it with berry jam.

Place it in the oven until browned, then remove it and let it cool slightly before serving or transferring it from the pan. Enjoy!
