Banana Peanut Butter Cookie
🍌🥜 Banana Peanut Butter Cookies — Soft, Chewy, and Totally Snack‑Worthy
Because sometimes the best way to eat fruit is… in cookie form.
These Banana Peanut Butter Cookies are the perfect mash‑up of two comfort food icons: the natural sweetness of ripe bananas and the rich, nutty goodness of peanut butter. They’re soft, chewy, and just sweet enough to feel like a treat — but wholesome enough that you can totally justify having one with your morning coffee.
They’re:
- Ridiculously easy — no fancy equipment, no complicated steps.
- Naturally sweetened — ripe bananas do most of the work.
- Kid‑approved — and grown‑up approved, too.
💬 Reader prompt: Are you team “eat the dough” or team “wait for the cookies”? (No judgment either way.)
I was a little giddy when I was making these cookies because I love peanut butter and I love bananas! These little gems are so moist and soft that they almost melt in your mouth!
Ingredients
- 1 ½ cups all‑purpose flour
- ½ teaspoon baking soda

- ¼ cup creamy peanut butter (or chunky if you like texture)

- Add Egg & Vanilla

- Combine
- Gradually mix in the flour mixture until a soft dough forms.
- Shape Cookies
- Roll dough into 1‑inch balls and place 2 inches apart on prepared baking sheets.

👩🍳 Cooking Tips
- Banana Ripeness: The spottier, the better — they’ll mash easier and add more natural sweetness.
- Peanut Butter Choice: Creamy gives a smoother texture, chunky adds crunch.
- Don’t Overbake: They’ll look slightly soft in the center when you pull them out — that’s perfect.
🎨 Recipe Variations
- Chocolate Drizzle: Melt dark chocolate and zig‑zag over cooled cookies.
- Oat Boost: Swap ½ cup flour for rolled oats for a heartier bite.
- Nut Swap: Try almond butter or cashew butter for a twist.
🧒 Kid Tips
- Let kids mash the banana — it’s messy but fun.
- Use mini cookie cutters to make “cookie shapes” for lunchboxes.
- Have them press the fork crisscross pattern — instant helper pride.
🛒 Grocery Hacks
- Buy bananas in bulk when they’re on sale, let them ripen, then freeze peeled halves for baking.
- Store peanut butter upside down to keep the oils from separating.
- Keep a “baking basics” bin in your pantry so you’re always ready for a cookie emergency.

💭 Final Thoughts
These cookies are proof that a little banana and peanut butter magic can turn a few pantry staples into something snack‑worthy and smile‑inducing. They’re quick, adaptable, and just the right amount of indulgent.
Whether you’re baking with kids on a rainy afternoon, whipping up a quick treat for unexpected guests, or just craving something that feels like a hug in cookie form, these Banana Peanut Butter Cookies are here for you. They’re the kind of recipe that doesn’t ask for perfection — just a few pantry staples, a ripe banana, and a little bit of love.
I love that they straddle that magical line between “comfort food” and “I can totally justify this as a snack.” The banana keeps them moist, the peanut butter gives them richness, and the flour gives them that classic cookie chew we all know and love. Plus, they’re endlessly adaptable — you can dress them up with chocolate chips, roll them in cinnamon sugar, or even sandwich them with a smear of Nutella if you’re feeling extra.
And here’s the thing: recipes like this aren’t just about the cookies. They’re about the moments you make while baking them. The little giggles when someone sneaks a taste of dough. The smell that fills your kitchen and makes everyone wander in asking, “Are those ready yet?” The way a plate of cookies on the counter somehow turns your home into the coziest place on earth.
So here’s my challenge to you — don’t just make these cookies and move on. Make them part of your story. Share them with a neighbor who could use a pick‑me‑up. Pack them in your kid’s lunchbox with a silly note. Bring them to your next book club or game night and watch them disappear.
And when you do, I want to see it! Post your creations with #BananaPBMagic so we can all drool together and maybe even swap ideas for the next great cookie mash‑up. Because here in our little corner of the internet, baking isn’t just about food — it’s about connection, creativity, and finding joy in the everyday.
Now go preheat that oven, friend. Your next batch of warm, peanut‑buttery, banana‑kissed happiness is waiting.

FYI… You can peel and freeze the over-ripe bananas for use in veggie smoothies. One ripe frozen banana can completely over power the taste of spinach, kale…or just about anything else.
