Preheat oven to 350°F. Line a baking sheet with parchment paper or a silicone mat.

Peel, core, and remove the seeds of the apple. Dice the apple into small pieces and place them in a medium bowl. Add pumpkin purée, coconut milk, and egg and combine well.

Place the oat flour and baking powder in a separate bowl and mix well.

Add flour mixture to the wet ingredients and combine until a dough forms.

Using a small ice cream scoop or a tablespoon, scoop out equal amounts of dough and form them with your hands into a cookie shape.

Place the formed treats on the prepared baking sheet and bake for 10-12 minutes.

Allow the treats to cool completely before removing them from the baking sheet.
