Preheat oven to 350 degrees F. Mix protein powder, coconut flour, and pumpkin puree together. (use your hands so a thick dough forms) Press down dough evenly in a parchment paper lined loaf pan.
In a separate bowl, combine peanut flour and water. Mix until a paste forms. Spread peanut powder mixture on top of protein dough. Sprinkle Nutsola (or granola) on top.
Bake for 20 minutes at 350 F. Remove from oven and let cool completely before lifting parchment paper out of the loaf pan. Slice and enjoy! Store in the fridge for up to 5 days.
