Preheat oven to 350 and prepare a lined baking sheet with parchment paper or a silpat baking sheet.
Mash bananas until smooth. Add bananas to a mixing bowl and stir in coconut oil and egg until combined
Add all remaining ingredients together in a large bowl + allow it to sit for 5 minutes (the chia seeds will start to bind + make the batter thick)
Scoop 1 tablespoons of dough and form into shape of a cookie. Make sure to press the cookies down flat. (Because these cookies do not have any baking powder/soda or flour, they do not rise or expand. The cookies will stay whatever shape you bake them at)
Bake at 350 for 10-15 minutes, or until cookies are a light brown on the edges.
Allow cookies to cool + store in an airtight container in refrigerator.
Notes
Substitutions for this banana breakfast cookies recipe:
Collagen- You can omit the collagen peptides from this recipe if you'd like. They add a little bit more protein so I always add them in. I haven't tried substituting protein powder for the collagen peptides but that might also work.
Oil - You can use olive or avocado oil in place of coconut oil
Chocolate chips - You can omit chocolate chips and add in dried fruit or nuts if you'd prefer
Banana - You can substitute banana with pumpkin puree or applesauce.
Quick cook oats: I haven't tried this recipe with quick cook oats but I think it would work!
