These banana oat breakfast cookies are flourless, made with ripe bananas, quick oats, and peanut butter, and naturally sweetened with maple syrup. They’re high in fiber, gluten-free, dairy-free, and ready in 20 minutes for an easy grab-and-go healthy breakfast cookie.
Preheat & prep the pans. Preheat your oven to 350°F and line two baking sheets with parchment paper.
Mash the bananas. In a large mixing bowl, mash the bananas until smooth. Make sure you have 1 cup mashed.
Add the wet ingredients. Stir in the egg, runny nut butter (I used peanut butter), maple syrup, and vanilla until combined.
Add the dry ingredients. Mix in the quick oats, cinnamon, and salt to form a thick batter.
Add mix-ins. Fold in walnuts and chocolate chips (optional). For a lower-sugar cookie, skip the chocolate chips.
Scoop the dough. Use a 1.5-tablespoon cookie scoop to portion the dough onto your baking sheets. No rolling needed — just drop, then gently press the tops to flatten slightly. The cookies won’t spread much.
Bake. Bake for 12–15 minutes, or until the bottoms are lightly golden.
Cool. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to finish cooling.
Notes
Light Flatten the Cookies: These cookies do not have baking soda or baking powder so that they won't spread. I recommend slightly tapping the tops to achieve a "cookie shape." Do not flatten them; they should be at least one inch thick.Mix-Ins: I left a whole section above with all the options from coconut to trail mix. As a rule of thumb, add a maximum of ⅔ cup of mix-ins to these breakfast cookies. This means, for example, that you can do ⅓ cup of walnuts and ⅓ cup of dried fruit. You pick the mix-in but keep to those measurements.Egg Replacement (Vegan): Substitute 1 egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) for a vegan option.Quick Oats vs. Rolled Oats: Quick oats work well for a smoother texture, but feel free to use old-fashioned oats if you prefer a chewier consistency.Storing: Store the cookies in an airtight container at room temperature for a few days, in the refrigerator for up to 7 days, or in the freezer for up to 5 months.Freezing: Freeze these banana bread breakfast cookies by placing them in a single layer on a sheet, then transfer them to a sealed freezer bag. They can be frozen for up to 2-3 months. Defrost in the refrigerator overnight or at room temperature for a few hours.The nutritional information below is for 1 of 18 cookies with chocolate chips and walnuts.
