Combine the oat flour, peanut butter, applesauce and eggs in a large bowl. Mix thoroughly. If the dough is sticky, add a little oat flour until you can handle the dough without it sticking to your hands.
Transfer dough to a flat surface and roll out to about 1/4 inch thickness. Using a cookie cutter, cut our your shapes. I use a large heart shape cookie cutter and get about 12 large cookies from this recipe.
Transfer onto a baking sheet lined with baking mat or parchment paper.
Bake 20-25 minutes until the cookies are dry and starting to darken at the edges.
Cool completely on a wire rack and store in an airtight container or bag in the refrigerator.
*NOTE - Make sure your Peanut Butter does not contain a sweetener called Xylitol , it can be poison to dogs!
