Prep: Preheat the oven to 350 F. Grease a muffin tin or use parchment liners.
Mix the dry ingredients: In a large mixing bowl, add almond flour, rolled oats, oat flour, protein powder, baking powder, baking soda, salt, cinnamon and nutmeg and whisk to combine.
Mix the wet ingredients: In a separate mixing bowl, add pumpkin puree, mashed banana, maple syrup, almond milk, egg, coconut oil and vanilla extract and whisk to combine.
Combine: Add the wet ingredients to the dry ingredients and stir until just combined.
Fill muffin tins: Divide the batter evenly among 6 muffin cups, filling each about 3/4 of the way full.
Bake: Bake for 25 minutes or until a toothpick inserted into the muffin comes out clean.
Cool: Cool for 5 minutes before transferring to a glass container. Store in the fridge for up to 7 days or freeze for up to 3 months.
Notes
You can make your own oat flour by grinding rolled oats in a coffee or herb grinder until a fine powder forms.
If you are strictly gluten-free, make sure to choose gluten-free oats.
