Preheat oven to 300ºF.

Add oats to a food processor until powdered, then add banana and peanut butter and blend until it becomes a dough-like texture.

Roll dough onto a floured surface, then use a cookie cutter to cut out treats. Add cut dog treats to a baking sheet lined with parchment or foil.

Bake for 25 - 30 minutes, cool, and serve one to your canine taste-tester.
