Peanut Butter Banana Cookies Ingredients
For the Batter
- All-Purpose Flour – Provides structure to the cookies; substitute with gluten-free flour for a gluten-free version.
- Salted Butter (1 stick, softened) – Adds richness and moisture; unsalted can be used with a pinch of salt added.
- Light Brown Sugar (1/2 cup, packed) – Sweetens and adds moistness; dark brown sugar works for a deeper flavor.
- Peanut Butter (1/2 cup) – The star of the show, adding flavor and fat; swap with other nut butters for variety.
- Ripe Banana (1/2 cup, mashed or 1 medium banana, sliced) – Brings natural sweetness and moisture; use overripe bananas for the best flavor.
- Large Egg (1) – Binds ingredients and helps the cookies rise; can substitute with a flax egg for a vegan option.
- Vanilla Extract (1 teaspoon) – Enhances the overall flavor; optional, but highly recommended for warmth.
- Baking Soda (1 teaspoon) – Leavening agent crucial for cookie texture; avoid substitutes to preserve fluffiness.
- Pinch of Salt – Balances sweetness and enhances flavor; don’t skip this essential ingredient.
- Granulated Sugar (1/3 cup, optional for rolling) – For a delightful crunchy surface; omit if you prefer softer cookies.
Step‑by‑Step Instructions for Peanut Butter Banana Cookies
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). Meanwhile, line two baking sheets with parchment paper to prevent the cookies from sticking. This step will ensure that your Peanut Butter Banana Cookies bake evenly, resulting in a delightful, golden texture.
Step 2: Cream Butter and Sugar
In a large mixing bowl, cream together one stick of softened salted butter and ½ cup of packed light brown sugar using an electric mixer. Mix on medium speed for about 2 minutes, until the mixture is fluffy and light in color. This key step adds air to the batter, enhancing your cookies’ texture.
Step 3: Add Key Ingredients
Next, incorporate ½ cup of peanut butter, one large egg, 1 teaspoon of vanilla extract, a pinch of salt, 1 teaspoon of baking soda, and ½ cup of mashed ripe banana into the bowl. Mix all the ingredients on medium speed for about 1-2 minutes until the mixture is smooth and well-combined, creating the delicious base for your Peanut Butter Banana Cookies.
Step 4: Mix in the Flour
Gradually add 1 cup of all-purpose flour to the wet mixture, mixing on low speed until just combined. Be careful not to overmix, as this could lead to tough cookies. You want the dough to be soft and slightly sticky, making it perfect for scooping and shaping your cookies.
Step 5: Scoop the Dough
Using a tablespoon or cookie scoop, drop rounded balls of cookie dough onto the prepared baking sheets, spacing them about 2 inches apart. Flatten each ball slightly with the back of a spoon to create an even surface. This ensures they bake uniformly, allowing that signature chewy texture in your Peanut Butter Banana Cookies.
Step 6: Bake the Cookies
Place the baking sheets in your preheated oven and bake for 10-12 minutes, or until the edges are lightly golden while the centers remain soft. Keep an eye on them as baking times may vary depending on your oven. You want to achieve that perfect balance of chewy and soft.
Step 7: Cool on a Rack
Once baked, remove the cookies from the oven and let them cool on the sheets for 3-4 minutes before transferring them to a wire rack. This cooling period allows them to set properly while maintaining a delightful soft texture, enhancing your enjoyment of these Peanut Butter Banana Cookies.

How to Store and Freeze Peanut Butter Banana Cookies
Room Temperature: Keep cookies in an airtight container at room temperature for up to 3 days to maintain their soft, chewy texture.
Fridge: For longer freshness, store in the fridge for up to a week. Make sure they are in a tightly sealed container to avoid drying out.
Freezer: Freeze cookies by laying them on a baking sheet until firm, then transfer to a freezer-friendly bag or container. They can be stored for up to 3 months.
Reheating: To enjoy warm cookies, reheat in the microwave for about 10 seconds or in an oven at 350°F (175°C) for a few minutes until warmed through.
Make Ahead Options
These Peanut Butter Banana Cookies are perfect for meal prep! You can prepare the cookie dough up to 24 hours in advance, storing it in an airtight container in the refrigerator. Additionally, the cookies can be baked and stored—simply allow them to cool completely and then refrigerate for up to 3 days. To maintain their delightful softness, keep them in an airtight container at room temperature. When ready to serve, warm them slightly in the microwave for a few seconds to revive their chewy texture, providing you with fresh-tasting cookies without the fuss, even on your busiest days!
Expert Tips for Peanut Butter Banana Cookies
-
Use Ripe Bananas: Make sure to use those overripe bananas with brown spots for the best flavor and natural sweetness in your Peanut Butter Banana Cookies.
