Instructions
Mix Everything Together
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- In a large bowl, mash your ripe banana until smooth.
- Add the peanut butter and maple syrup, stirring until well combined.
- Pour in the rolled oats and mix everything together until each oat is coated and the mixture holds together when pressed.
Pro Tip: Let the mixture rest for 5 minutes – this helps the oats absorb moisture for better texture.
Shape and Bake

- Press each ball down gently with a fork to create the classic crosshatch pattern.
- Bake for 12-15 minutes until the edges are set and lightly golden. The centers should still look slightly soft.
Cool and Enjoy
Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. They'll firm up as they cool but stay perfectly chewy inside.
- Step 1: Mix Everything Together
Combine all four ingredients until the oats are fully coated and the dough holds together.
- Step 2: Shape and Bake
Shape the dough into balls, press gently with a fork, and bake until golden around the edges.
- Step 3: Cool and Enjoy
Let the cookies cool for a few minutes before enjoying their chewy goodness.
Expert Cooking Tips & Tricks
Even the simplest recipes; like these 4 ingredient peanut butter oatmeal cookies; can benefit from a few insider tips to take them from great to unforgettable.
- Master the Texture
Want chewier cookies? Try taking them out of the oven a minute or two early. Prefer a crisp edge? Let your 4 ingredient peanut butter oatmeal cookies bake an extra 2–3 minutes until they’re golden and lightly browned around the edges. - Elevate the Flavor
While the base recipe is delicious on its own, a dash of cinnamon or a splash of vanilla extract adds a layer of warmth that makes your 4 ingredient peanut butter oatmeal cookies taste like they came from a bakery; without losing that homemade charm. - Keep It Even
Uniform size means even baking. Use a cookie scoop or a tablespoon to keep things consistent, so no cookie gets left behind (or overbaked). - Control the Spread
If your cookies flatten out too much, chances are your banana is super ripe or your peanut butter has too much oil. A quick fix? Chill the dough for 15 minutes before baking. It helps keep your 4 ingredient peanut butter oatmeal cookies thick, soft, and picture-perfect.
Recipe Variations & Dietary Modifications
One of the best things about 4 ingredient peanut butter oatmeal cookies is how flexible they are. With just a few smart swaps, you can tailor this recipe to your taste or dietary needs; without sacrificing flavor or texture.
- Banana-Free Option
Not a fan of bananas? No problem. Swap the mashed banana for ¼ cup of applesauce or mix 2 tablespoons of maple syrup with a flax egg (that’s 1 tablespoon ground flaxseed mixed with 3 tablespoons water; let it sit for 5 minutes). It keeps the cookies moist and holds everything together beautifully. - Chocolate Twist for Choco-Lovers
Craving something richer? Stir in ¼ cup of mini chocolate chips or a spoonful of cocoa powder. You’ll end up with 4 ingredient peanut butter banana oatmeal cookies that satisfy your sweet tooth and chocolate cravings in one bite. - Protein-Packed Upgrade
If you're looking to boost your snack game, add a scoop of vanilla protein powder. Just add an extra tablespoon of liquid; like almond milk or maple syrup; to keep the cookie dough balanced. - Sugar-Free Swap
Want a less sweet version? Go for sugar-free maple syrup or monk fruit sweetener. Your 4 ingredient peanut butter oatmeal cookies will still turn out delicious, just with a milder sweetness that’s perfect for those watching their sugar intake. - Vegan-Friendly Tip
This recipe is naturally vegan if you use maple syrup instead of honey. Just make sure your oats are certified vegan (some brands process oats with dairy or honey), and you're all set for plant-based baking success.
Equipment
- Large Mixing Bowl: A wide bowl makes mixing easier and prevents ingredients from flying out.
- Cookie Scoop: A 1.5-tablespoon cookie scoop creates perfectly uniform cookies every time. It's worth the small investment.
- Parchment Paper: Never skip this step. It prevents sticking and makes cleanup effortless.
- Wire Cooling Rack: Allows air to circulate under the cookies, preventing soggy bottoms.
- Budget Alternative: Don't have a cookie scoop? A regular tablespoon works fine – just try to keep the portions consistent.
Storage & Meal Prep Tips
One of the best things about 4 ingredient peanut butter oatmeal cookies; aside from their simplicity—is how easy they are to store and prep ahead.
- Room Temp: Let cookies cool completely, then store in an airtight container for up to a week. Use parchment between layers to avoid sticking.
- Fridge: These cookies taste great chilled and last up to 10 days. The texture becomes a little denser but just as delicious.
- Freezer: Freeze baked cookies for up to 3 months. Thaw at room temp for 30 minutes, and they’re ready to enjoy.
- Meal Prep Hack: Scoop the dough into balls, freeze on a tray, then transfer to a freezer bag. Bake straight from frozen; just add 1–2 minutes to the time for fresh 4 ingredient peanut butter oatmeal cookies anytime.
