Preheat your waffle maker according to the manufacturer’s instructions. If it is not non-stick, lightly grease it with a small amount of coconut oil.

In a medium bowl, whisk together the unsweetened applesauce, egg, and melted coconut oil until smooth.

Add the oat flour and baking powder to the bowl and stir until a thick, smooth batter forms.

Scoop about 2–3 tablespoons of batter into the center of the preheated waffle maker, spreading slightly if needed.

Close the waffle maker and cook for about 3–5 minutes, or until the waffle is golden brown and fully set.

Carefully remove the waffle and place it on a wire rack to cool completely before serving to your dog.

Repeat with the remaining batter.

Store cooled waffles in an airtight container in the refrigerator for up to 7 days or freeze for longer storage. Thaw in the refrigerator before serving.
