Preheat oven to 350°F (175°C). Stir together peanut butter, applesauce, egg, and honey until smooth.

Add the flour and mix until a soft dough forms.

Roll the dough to 1/4 inch thickness on a floured surface. Cut with a small cookie cutter.

Place on a parchment-lined baking sheet and bake 10 to 12 minutes, until edges are firm. Cool completely before serving.
