Ingredients for Banana Cookies 3 Ingredient

Main Ingredients
- 2 large very ripe bananas (about 1 cup mashed) – Look for bananas with brown spots for maximum sweetness
- 2 cups quick oats – Old-fashioned oats will work too, but will give a chewier texture
- 1/4 cup peanut butter (smooth or crunchy) – Can substitute with almond butter, cashew butter, or sunflower seed butter for a nut-free option
Optional Add-ins (for customization)
- 1/4 teaspoon cinnamon
- 1/4 cup chocolate chips (dairy-free if needed)
- 1/4 cup chopped nuts or seeds
- 1/4 teaspoon vanilla extract
- Pinch of salt (enhances flavor, especially if using unsalted nut butter)
Essential Tools
- Mixing Bowl – A medium-sized bowl is perfect for this small batch of cookie dough
- Fork or Potato Masher – For mashing the bananas to a smooth consistency
- Measuring Cups – For accurate measurements of oats and nut butter
- Cookie Scoop or Spoon – To portion the cookies evenly for consistent baking
- Baking Sheet – A standard baking sheet works perfectly
- Parchment Paper or Silicone Baking Mat – Prevents sticking and makes cleanup easier
Don’t have a cookie scoop? A regular tablespoon works fine for portioning the dough. No parchment paper? A lightly oiled baking sheet will work in a pinch, though the bottoms may brown more quickly.
How to Make Banana Cookies 3 Ingredient

Step-by-Step Instructions
1. Prepare Your Baking Space
- Preheat your oven to 350°F (175°C).
- Line a baking sheet with parchment paper or a silicone baking mat.
2. Mash the Bananas
- In a medium mixing bowl, thoroughly mash the ripe bananas with a fork or potato masher until smooth with minimal lumps.

3. Add Peanut Butter
- Add the peanut butter to the mashed bananas.
- Mix until well combined and creamy.
4. Incorporate the Oats
- Add the quick oats to the banana-peanut butter mixture.
- Stir until all ingredients are thoroughly combined. The mixture should be thick and somewhat sticky.
- If adding any optional ingredients (cinnamon, chocolate chips, etc.), fold them in now.
5. Form the Cookies
- Using a cookie scoop or spoon, portion about 2 tablespoons of dough for each cookie.
- Place on the prepared baking sheet, leaving about 1 inch between cookies (they won’t spread much).
- Slightly flatten each cookie with the back of a spoon or your fingers, as they won’t spread much during baking.
6. Bake to Perfection
- Bake in the preheated oven for 12-15 minutes until the edges are golden and the cookies feel set.
- For softer cookies, bake for 12 minutes; for firmer cookies, bake for 15 minutes.

Top Tips for Mastering Banana Cookies 3 Ingredient
Perfect Ingredient Selection
- Banana Ripeness Matters: The spottier and darker your bananas, the sweeter your cookies will be. Yellow bananas with just a few spots won’t provide enough natural sugar.
- Oat Options: Quick oats create a softer cookie, while old-fashioned rolled oats make a chewier, more textured cookie. Steel-cut oats won’t work well in this recipe.
- Nut Butter Consistency: Room temperature nut butter mixes more easily. If your nut butter is refrigerated, microwave it for 10-15 seconds before measuring.
Preparation Techniques
- Don’t Overmix: Stir just until ingredients are combined to maintain a tender texture.
- Uniform Size: Using a cookie scoop ensures even baking and consistent results.
- Flatten Slightly: These cookies won’t spread much during baking, so gently press them down to your desired thickness before baking.
Common Mistakes to Avoid
- Using Underripe Bananas: This results in bland cookies that lack natural sweetness.
- Not Mashing Bananas Thoroughly: Large banana chunks can make the cookies fall apart.
- Overlooking Salt: Even with just three ingredients, a tiny pinch of salt can enhance all the flavors dramatically.
For Dietary Needs
- Gluten-Free: Ensure you’re using certified gluten-free oats.
- Nut-Free: Substitute sunflower seed butter or tahini for peanut butter.
- Extra Protein: Add a scoop of your favorite unflavored or vanilla protein powder.
Storage and Reheating Tips
Countertop Storage
- Store cooled cookies in an airtight container at room temperature for up to 2 days.
- Place parchment paper between layers to prevent sticking.
Refrigerator Storage
- These cookies will stay fresh in the refrigerator for up to 5 days in an airtight container.
- The cool temperature will make them firmer, which some people prefer.
Freezer Instructions
- Freeze baked and cooled cookies in a single layer on a baking sheet, then transfer to a freezer bag or container.
- They’ll keep for up to 3 months frozen.
- Alternatively, freeze the raw cookie dough balls and bake from frozen, adding 2-3 minutes to the baking time.
Reheating Methods
- Microwave a refrigerated or frozen cookie for 10-15 seconds for that just-baked softness.
- Warm in a toaster oven for 2-3 minutes at 300°F for crisper edges.
Creative Leftover Uses
- Crumble cookies over yogurt for a parfait-like breakfast
- Blend with a frozen banana and milk for a “cookie dough” smoothie
- Use as a base for a healthy banana cream pie by pressing into a pie dish before adding filling

Frequently Asked Questions
Can I use steel-cut oats instead of quick oats?
No, steel-cut oats won’t work well in this recipe as they require much longer cooking times and more liquid. Stick with quick oats or old-fashioned rolled oats for the best texture.
How ripe should my bananas be?
The riper, the better! Look for bananas with plenty of brown spots or even mostly brown peels for maximum natural sweetness.
Are these cookies gluten-free?
These cookies can be gluten-free if you use certified gluten-free oats. While oats are naturally gluten-free, they’re often processed in facilities that handle wheat, so certification matters for those with celiac disease or severe gluten sensitivity.
Can I make these cookies nut-free?
Absolutely! Substitute the peanut butter with sunflower seed butter, tahini, or pumpkin seed butter for a completely nut-free version that’s safe for school lunches.
Why are my cookies too soft or falling apart?
This could be because your bananas were very large, adding too much moisture. Try adding an extra 2-3 tablespoons of oats to absorb the excess moisture.
