Preheat oven to 350F. Line a large baking sheet with a silicone baking mat or parchment paper.
In a large bowl, combine pumpkin, eggs, and peanut butter. Stir until completely combined.
1 cup pumpkin puree, 2 large eggs, ⅓ cup peanut butter
Add in flour and pumpkin pie spice (or cinnamon) - stirring just until combined.
2 cups whole wheat flour, ½ teaspoon pumpkin pie spice
Lightly flour a flat surface and roll out dough to one quarter inch, using flour as needed to keep dough from sticking.
Cut shapes out of dough (here is the cookie cutters I used) and place on prepared baking sheet. Bake for 20 to 40 minutes - depending on desired level of crunchiness.
Remove treats from oven and let cool on a cooling rack. Store in an airtight container for up to 1 month in the refrigerator or 6 months in the freezer.
