Preheat the oven to 350° F

In a medium bowl, stir together the flour, oats and flaxseed.

Add beef broth and peanut butter. Mix well. The mixture will form a thick dough.

Form into a ball and turn out on a lightly floured surface.

Roll to about 1/4 inch thickness and cut into desired shape using a cookie cutter or the top of a glass.

Bake for about 20 minutes or until golden brown, flipping halfway.

Cool completely, then keep in an airtight container for about one week.
