Banana Peanut Butter Cookies
So you’ve got a couple of sad bananas on your counter, staring at you like, “We used to be yellow.” And now you’re debating between banana bread… or pretending you don’t see them. Hold up. What if I told you that in less than 30 minutes, those mushy legends could turn into soft, chewy, slightly addictive banana peanut butter cookies? No mixer drama. No complicated steps. Just simple, cozy goodness. Let’s do this.
Why This Recipe Is Awesome
First of all, it’s ridiculously easy. Like, “I-made-this-half-asleep” easy. If you can mash a banana and stir stuff in a bowl, you’re qualified. Second, it’s made with basic pantry staples. No weird ingredients that require a treasure hunt. Third, the texture? Soft in the middle, lightly crisp at the edges. And the flavor combo of banana + peanut butter? Chef’s kiss. Sweet, nutty, comforting. Also… it’s a sneaky way to use up overripe bananas without committing to a whole loaf of banana bread. Sometimes you want cookies, not a responsibility. And yes, they’re naturally flourless if you use the simple 3-ingredient version. Which means fewer dishes. We love that.
Ingredients You’ll Need
Here’s the lineup. Nothing fancy. Nothing dramatic.
- 2 ripe bananas – The spottier, the better. If they look questionable, they’re perfect.
- 1 cup peanut butter – Creamy works best, but crunchy is fun if you like surprise texture.
- ¼–⅓ cup brown sugar or honey – Adjust depending on how sweet your bananas are.
- 1 teaspoon vanilla extract – Optional, but highly recommended. It just makes everything better.
- ½ teaspoon baking soda – For a little lift. Don’t skip unless you enjoy dense hockey pucks.
- Pinch of salt – Balances sweetness.
- Optional add-ins:
- Chocolate chips (obviously)
- Chopped peanuts
- Cinnamon
- A few oats for texture
That’s it. No flour. No butter. No complicated steps. We’re keeping this chill.
Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 350°F (175°C). Yes, actually preheat it. Line a baking tray with parchment paper. Trust me, scraping stuck cookies is not a personality trait.
2. Mash the Bananas
Throw the bananas in a bowl and mash them until mostly smooth. A few tiny lumps are fine. Big chunks? Not so cute.
3. Mix It All Together
Add peanut butter, sugar (or honey), vanilla, baking soda, and salt. Stir until fully combined. The mixture should look thick and slightly sticky. If you’re adding chocolate chips or extras, fold them in now. Try not to eat half the dough. Or do. I’m not judging.
4. Scoop and Shape
Scoop tablespoon-sized portions onto the baking sheet. Flatten them slightly with a fork. These don’t spread much, so shape them how you want them to look.
5. Bake
Bake for 10–12 minutes. The edges should look set and lightly golden. The centers might look soft that’s good. They firm up as they cool.
6. Cool (Yes, Actually Wait)
Let them sit on the tray for 5 minutes before moving them. They’re delicate when hot. Give them a minute to get their life together. And that’s it. You just made cookies out of bananas. Look at you.
Common Mistakes to Avoid
Let’s save you from cookie heartbreak.
1. Using underripe bananas.
If your bananas are yellow and firm, your cookies will taste bland. You want brown spots. Embrace the chaos.
2. Skipping the baking soda.
It’s small, but mighty. Without it, your cookies may turn dense and sad.
3. Overbaking.
They’ll look soft when done. That’s normal. If you wait until they look “fully cooked,” you’ll end up with dry cookies.
4. Using super oily peanut butter without stirring.
Natural peanut butter separates. Stir it first unless you enjoy inconsistent cookie texture.
5. Forgetting to line the tray.
Unless you want to practice chiseling cookies off metal, use parchment paper. You’re welcome.
Alternatives & Substitutions
Because sometimes you open the pantry and… surprise. Something’s missing.
No peanut butter?
Use almond butter or cashew butter. Even sunflower seed butter works. Same method, same vibe.
Want it sweeter?
Add a little more brown sugar or toss in chocolate chips. IMO, chocolate makes everything better.
Need it vegan?
Good news it already is (if you use plant-based sweetener). No changes needed.
Want more structure?
Add 2–3 tablespoons of oat flour or regular flour if you prefer a firmer cookie.
Trying to make it “healthier”?
Skip added sugar and rely on ripe bananas. Add dark chocolate chips and call it balanced.
Craving crunch?
Use crunchy peanut butter or sprinkle chopped nuts on top before baking. See? Flexible. Adaptable. Basically the yoga instructor of cookies.
