Ingredients You’ll Need

The ingredient list is short, sweet, and full of pantry staples:

2 cups quick oats
½ tsp cinnamon
½ tsp baking powder
½ tsp baking soda
½ tsp salt
2 ripe bananas, mashed
½ cup peanut butter
2 tbsp honey (local and raw preferred)

¼ cup chocolate chips (optional, but highly recommended!)

Equipment You’ll Need

One of the best things about this recipe is how low-effort it is. You’ll only need a few basic kitchen tools:

Mixing bowl
Fork or potato masher (for mashing bananas)
Measuring cups and spoons
Spatula or spoon
1/4 cup scoop or cookie scoop
Fork (for flattening)
Baking sheet
Parchment paper

No fancy mixers, chill time, or complicated prep required. Just mix, scoop, and bake.

How to Make Banana Oat Peanut Butter Cookies

1. Prep Your Oven

Start by preheating your oven to 350°F and lining a baking sheet with parchment paper. This keeps the cookies from sticking and makes cleanup a breeze.

2. Mash the Bananas

In a medium mixing bowl, mash your ripe bananas using a fork or potato masher. They should be smooth with just a few small lumps.

3. Combine the Ingredients

Add the peanut butter, honey, and vanilla extract to the mashed bananas. Stir until well blended.

Next, add in the quick oats, cinnamon, baking powder, baking soda, and salt. Mix until everything is evenly combined. If using, fold in the chocolate chips at this point.

4. Shape the Cookies

Use a 1/4 cup measuring cup or cookie scoop to portion out the dough onto your parchment-lined baking sheet. The dough won’t spread in the oven, so flatten each cookie gently with a fork in a crisscross pattern to help them cook evenly.

5. Bake and Cool

Bake the cookies at 350°F for about 15 minutes, or until the edges are lightly golden and the centers are set. Allow to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.

Tips for Best Results

Use overripe bananas for maximum natural sweetness and moisture.
Natural peanut butter (the kind with just peanuts and salt) works great, but you can use any variety you like.
For extra texture, stir in a tablespoon of chia seeds, flaxseed, or hemp hearts.
These cookies don’t spread while baking, so shaping them beforehand is key.
Want more structure? Add 1 tablespoon of coconut flour or almond flour to the batter.

Recipe Variations and Swaps

These cookies are super flexible, which makes them perfect for adapting to your taste or pantry:

Nut-Free Version

Substitute sunflower seed butter or Wowbutter for peanut butter to make these allergy-friendly.

Vegan-Friendly

Swap out the honey for maple syrup or agave nectar to keep the recipe vegan.

Add-Ins

Chopped nuts (walnuts, pecans, almonds)
Dried fruit (raisins, cranberries, chopped dates)
Coconut flakes for a tropical twist

Chocolate Fix

If you’re a chocolate lover, increase the chocolate chips to ½ cup or drizzle the cooled cookies with melted dark chocolate.

Frequently Asked Questions

Can I use rolled oats instead of quick oats?

Yes, but the texture will be slightly chewier. For a smoother cookie, give rolled oats a quick blitz in the food processor before using.

Are these cookies good for kids?

Absolutely! They’re soft, naturally sweet, and full of healthy ingredients. Plus, they make a great lunchbox treat.

Can I make them in advance?

Yes! These cookies can be made ahead and stored in the freezer or fridge. They taste just as good (if not better) the next day.

Do I have to use chocolate chips?

Not at all. They’re optional, but they do add a fun pop of sweetness. You could also try white chocolate, carob chips, or leave them out entirely.

Are they suitable for breakfast?

Definitely. They’re filling, nutrient-dense, and way better than grabbing a sugar-laden bar on the go.
