Preheat oven to 350°F / 177°C / Gas Mark 4. Line a baking sheet with parchment paper and set aside.

Add oats to the bowl of a food processor.

Let machine run for 2 - 3 minutes, until oats are almost flour consistency with a few big pieces left.

Add flour, applesauce, coconut oil, banana, sweet potato and egg to bowl of food processor.

Pulse a few times to break up cooked sweet potato and move ingredients around.

Run food processor for a minute or two until dough looks uniform.

Sprinkle the countertop with a few tablespoons of flour, then turn the dough out onto the countertop. (The dough will be sticky. If it is too sticky to roll out, work a few more tablespoons of flour into the dough until you are able to work with it)

Roll the dough out to roughly 1/8" thick on a floured surface. Sprinkle the top of the dough with a little extra flour and flour the rolling pin.

Dip the cookie cutter into a bit of flour, then cut treats out with cookie cutter and place on baking sheet. Bake for 16 - 18 minutes, rotate tray halfway through.

Cool completely before giving to your dog.
