Get out and measure your ingredients.
Add flour, pumpkin, peanut butter, egg, and salt together in a medium mixing bowl.
Stir and once blended, slowly add water until the dough forms a ball.
Place dough on cutting board.
Roll dough out on a floured surface until it is about ¼-inch thick. Using a pizza cutter, cut dough into small rectangles.
If needed, re-roll scraps of dough and cut remaining into rectangles as well.
Place rectangles into a greased air fryer basket without them touching. You will have to do a few batches.
Air fry at 370ºF for 5-7 minutes or until treats are golden brown.
Serve and watch them enjoy every bite!
