🛒 Tools & Equipment I Recommend

How to Make Easy Flourless Peanut Butter Banana Cookies – Cozy, Chewy, and Gluten-Free Treat
- Prep oven and pan: Preheat oven to 350°F. Line a baking sheet with a silicone mat or parchment. This step prevents sticking, which is crucial for flourless cookies.
- Mash banana and mix wet ingredients: In a large bowl, mash the ripe banana until very smooth. Whisk in peanut butter, brown sugar, egg, and vanilla extract until fully combined and no lumps remain.
- Add salt and stir: Sprinkle kosher salt into the bowl and stir until just blended. Don’t overmix—just enough to combine everything.
- Scoop cookies: Using a medium cookie scoop or two spoons, scoop 1 ½-tablespoon mounds of dough onto the baking sheet. Leave 2 inches between each for spreading.
- Bake: Bake 10–12 minutes until edges turn golden and centers look just set. Cookies will still look soft; they firm up as they cool.
- Cool on pan: Let cookies cool on the baking sheet for at least 8 minutes before moving to a rack. Moving too soon causes breakage.
- Add optional toppings: Drizzle melted peanut butter or sprinkle sea salt flakes on top if desired. Serve with extra banana slices for a fresh touch.
Cook's Tips for Perfect Easy Flourless Peanut Butter Banana Cookies – Cozy, Chewy, and Gluten-Free Treat
- Cookie texture: For maximally chewy cookies, underbake slightly. Look for set edges and a soft-looking center out of the oven.
- Common mistake and fix: Cookies fall apart if moved too soon. Let them cool fully on the baking sheet to solidify before transferring.
- Banana selection: Ripe, spotted bananas prevent a rubbery texture—avoid green or just-yellow bananas.
- Batch size tip: If doubling the recipe, bake only one tray at a time for even heat—crowded ovens cause uneven cookies.

Easy Flourless Peanut Butter Banana Cookies – Cozy, Chewy, and Gluten-Free Treat FAQs
Yes, you can make the dough and portion onto a baking sheet, then chill or freeze. Bake straight from the freezer; add a minute or two. Already-baked cookies store well for several days in an airtight container. Chilling the dough before baking also helps cookies hold their shape. This is perfect for prepping treats for cozy fall gatherings.
This is the most common failure. It usually happens from moving the cookies before cooling or using too much banana. Always let the cookies cool fully on the sheet to set. Stick to about half a cup mashed banana and measure ingredients accurately. A silicone baking mat also helps with gentle release.
Absolutely. Flash-freeze baked cookies or dough balls, then stack with parchment between. Thaw on the counter or bake dough balls straight from frozen. Finished cookies stay chewy if you microwave them briefly before serving. Use within 2 months for the best flavor and texture.
You can skip the brown sugar if your banana is very ripe, but cookies will be softer and less chewy. Consider using a sugar substitute or just using banana for sweetness. Results will be less golden and more cakey, but still tasty. Using regular fine sugar won’t work as well for a chewy result. Test a half-batch the first time for best results.
These cookies use simple, whole ingredients—banana and peanut butter provide natural sweetness and protein. There’s no flour or dairy. While they’re still a treat, they’re much lighter than most traditional cookies and naturally gluten-free. For a lower sugar option, use an extra-ripe banana and skip the extra sugar.
