In a small mixing bowl mash the ripe banana, add in the peanut butter, flax&water, turmeric, pepper, and coconut oil. Mix well using an electric mixer on low to avoid splatter.
In a large mixing bowl place the flour. Add in the wet mixture and using the same electric mixer blend well till you have a crumbly texture similar to shortbread.
Preheat oven to 350F.
Using hands compress the crumbles together till you form a large ball of dough. Now divide into sizes suitable for your dog. You may use cookie cutter shapes or doggie biscuit cutter. I just formed small balls and smooshed them down.
Place on a cookie sheet and bake for 15 mins. Allow to cool completely before giving to your pooch.
Optional: You can place a drop of pet safe hemp oil or CBD on each cookie once they are cooled for added healthy benefits.
