Why You'll Love Them
These peanut butter banana cookies are a twist on oatmeal cookies and peanut butter cookies in one, with sweet bananas pulling it all together!

All you need are 5 or 6 easy ingredients and about 25 minutes to make a batch!
Ingredients and Substitutions
- oats - I used old fashioned rolled oats since we always have some in the pantry. Quick oats will also work if that's what you have.
- bananas - use bananas with plenty of dark spots on the peels. They should smell very fragrant and sweet and be easy to mash. This is important for the overall flavor and texture of the cookies.
- peanut butter - I used salted, natural, chunky peanut butter. It shouldn't be overly thin or oily. If using unsalted, add a generous pinch of salt to the mixing bowl.
- flour - a small amount of flour helps bind the cookies. I used oat flour, but other types should work fine, such as all-purpose (regular or gluten-free), whole wheat, etc.
- sweetener - optional; for a less sweet, more wholesome-tasting cookie feel free to skip the sugar. You can use regular granulated, brown sugar, coconut sugar, or a sugar alternative for this extra bit of sweetness.
- chocolate chips - look for dairy-free semi-sweet chocolate. If you have a favorite brand of sugar-free chocolate chips that's great, too.

How to Make Peanut Butter Banana Cookies
Preheat the oven to 350°F, and line a baking sheet with parchment. Mash the bananas in a large mixing bowl, then measure to make sure you have 1 cup.
Stir in the peanut butter. Next, add the oats, flour, and sugar, and mix well. Fold in the chocolate chips.
Using a tablespoon or large cookie scoop, measure out 2 tablespoons of dough per cookie. Use your palms to roll into a ball, then flatten into shape.
Place on the prepared baking sheet, and bake for 9 to 11 minutes or until the cookies appear lightly set and golden.
Tip! When forming the cookies, try to arrange the chocolate chips near the tops of the cookies and not too close together. This helps the mixture hold together and ensures tasty chocolate in each bite!
- with spices - add cinnamon or pumpkin spice
- nuts - fold in chopped walnuts or pecans
- dried fruit - raisins, currants, or cranberries are right at home in this recipe, like banana oatmeal raisin cookies.
- other nut/seed butters - instead of peanut butter, try them with sunbutter, cashew, or almond butter.
How to Store
Since these cookies are fairly moist, I like to store them in the refrigerator to extend freshness. Place in an airtight container and store for up to 5 days.
The cookies can also be frozen. Wrap well to protect from air, and freeze for up to 2 months.
Make sure to use very ripe bananas since they contribute most of the moisture and sweetness in the recipe. The bananas should have a lot of dark spots, smell sweet, and be easy to mash.
