Add peanut butter and banana to the food processor and blend until fully combined.

Add most of the flour to the mix. Save a few tablespoons to use for dusting the roller. Give it a good mix. Then add in water to moisten a little more.

Dump mixture onto floured area. Should look like wet sand.

Press the mixture into a ball.

Lightly dust the rolling pin with flour and roll the dough out until it is about 1/4 to 1/2 inch thick.

Use the cookie cutter to cut out the cookies. You will have to roll the cut-off pieces out a few times until it is all used up.

Place cookies on the baking sheet. I used a silicone mat on mine. Bake in a preheated oven at 300 degrees for 20 - 25 minutes. When done the bottoms will be lightly golden and the cookies should be hard.

Allow to fully cool before serving.
