Preheat oven to 350℉.
Combine dry ingredients (oats, flour, and cinnamon) in bowl.
In a separate small bowl, stir together wet ingredients (eggs, pumpkin and peanut butter).
Add wet ingredients to dry and stir until evenly combined and creates dough. The dough should be a moist crumble and packs together.
Roll dough out on a floured surface to approximately ¼” in thickness. Use cookie cutter to create individual treats. Place on a parchment lined baking sheet.
Bake for 30 minutes at 350℉.
Transfer treats to a cooling rack. The treats will harden as they cool.
