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

Chop the apple into small pieces.

In a medium bowl, mix together the chopped apple, eggs, applesauce and peanut butter.

Combine the oat flour and rolled oats in a separate large bowl.

Add the wet ingredient mixture to the dry ingredient mixture and combine well to form a dough.

Turn the dough out onto a smooth surface. Using your hands or a spoon, combine the ingredients until you have a dough. Flatten evenly with your hands or a rolling pin to about ¼ to ½-inch thickness.

Using a cookie cutter, cut out the dog treats and place them on a greased baking sheet or use parchment paper to cover the baking sheet.

Bake for 20 to 25 minutes.

In a small bowl, add peanut butter and coconut oil. Microwave for 30 seconds or until melted. Stir well.

Drizzle the mixture over the treats.
