Preheat oven to 300 degrees. Mix together the egg, pumpkin puree and coconut oil (if using)

Slowly add the flour until a nice dough forms. Temperature can affect the dough, so just add more flour until it's not sticky. Roll the dough out onto a floured surface. It should be about 1/4 inch thick.

Cut into desired shape. I used a dog bone shaped cookie cutter or a heart for smaller treats.

Sprinkle oats on top (if desired) and press them into the treats so they bake in. Put the treats on a parchment lined sheet pan and bake for 30-40 minutes checking halfway through. You want a nice crunchy biscuit texture.
