Preheat the oven to 350 degrees Fahrenheit and line a baking sheet with parchment paper.

In a mixer, beat together the peanut butter, egg, banana, and maple syrup until fully combined. Gradually add the wheat flour and mix until a crumbly dough forms.

On a floured surface, roll out the dough to about 1/2 inch thickness. Use a cookie cutter to cut into desired shapes.

Arrange the cutouts on the prepared baking sheet and bake for 15-25 minutes until golden brown. Cool before serving.
