Pre-heat oven to 350 degrees Fahrenheit.
On medium speed, beat pumpkin, peanut butter, and eggs with an electric mixer.
On low speed, gradually add flour until the dough pulls away from the bowl.
Place a large piece of parchment paper on the counter and sprinkle with flour.
Flour your hands and knead the dough several times before placing it on the parchment paper.
Place dough on parchment paper, flatten with your hands, and place another piece of parchment paper on top.
Roll out dough to 1/4-inch thickness.
Remove the top piece of parchment paper and cut the dough. You cut the dough into squares using an oiled pizza cutter or knife or use an oiled cookie cutter.
Bake for 20-25 minutes in the 350-degree oven. When cooled, store in an air-tight container.
