Combine all ingredients in a large bowl and knead until a dough ball forms. If it's too sticky, add a little more flour.
Roll it out on a lightly floured surface until it's about an inch thick. Cut into shapes with cookie cutters or treat molds.
Place the cutouts or the mold sheets on a baking pan and bake for about 20-25 minutes.
Remove them from the oven and let them cool completed before handling.
