Preheat your oven to 350F and line a baking sheet with parchment paper (or a baking mat).
Beat pumpkin puree, peanut butter, and eggs until well combined.
Gradually add 5 cups of flour and beat until incorporated. Now add 1/4 cup of flour at a time until your dough is not sticky.
On a floured surface, knead dough until it comes together. Roll dough to 1/4 inch thickness using a rolling pin. Use your favorite shaped cookie cutter or pizza cutter to cut into shapes or squares.
Place treats into the oven and bake for about 20-25 minutes or until edges are golden brown.
Store in an airtight container. You can freeze them and take them out as needed.
