🛒 Ingredients You’ll Need
The best part? These cookies require pantry staples you probably already have. Here’s your shopping list:
Wet Ingredients
- 1 cup ripe mashed banana (2 large bananas)
- 1 cup creamy peanut butter (natural or conventional)
- 1/2 cup brown sugar (light or dark)
- 1 tsp vanilla extract
- 1 large egg (room temperature)

Dry Ingredients
- 1 1/4 cups all-purpose flour
- 1 tsp baking soda
- 1/2 tsp salt
Optional Mix-ins
- 1/2 cup chocolate chips (for a Reese’s vibe)
- 1/4 cup chopped peanuts or walnuts (for crunch)
- 1/2 cup rolled oats (for texture)
- 1/2 tsp ground cinnamon (for warm flavor)
🍴 Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a nonstick silicone mat.
Step 2: Mash Bananas
In a large mixing bowl, mash the bananas with a fork or potato masher until smooth. Some small lumps are okay.
🍌 Tip: The darker and spottier the banana, the better. They’ll be sweeter and more flavorful.
Step 3: Mix Wet Ingredients
Add peanut butter, brown sugar, egg, and vanilla to the mashed banana. Whisk or stir vigorously until smooth and fully combined.
Step 4: Add Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually fold the dry ingredients into the banana mixture using a spatula or wooden spoon.
Step 5: Stir in Add-Ins
If using chocolate chips, nuts, or oats, fold them in now.
Step 6: Scoop and Shape
Using a cookie scoop or tablespoon, drop dough balls onto your prepared baking sheet. Slightly flatten the tops with a fork or your fingers.
Step 7: Bake
Bake for 9–12 minutes until the edges look set and lightly golden. The centers may appear soft—that’s perfect!
⏱️ Tip: Don’t overbake! These cookies are best soft and chewy.
Step 8: Cool
Let the cookies cool on the tray for 5 minutes, then transfer to a wire rack to cool completely.

🧁 Texture & Taste Profile
- Texture: Soft, slightly chewy, and tender. Almost cake-like in the center.

If you love banana bread, but wish it came in cookie form—you’ve found your match.
👩🍳 Baking Science: Why It Works
Bananas serve as:
- A natural sweetener
- A moisture agent
- A partial egg substitute
Peanut butter brings:
- Fat for richness
- Protein for structure
- Flavor that complements banana beautifully
Brown sugar adds moisture and a deeper flavor, while baking soda helps the cookies rise just enough without puffing up like muffins.
🔄 Make It Your Own: Variations & Add-Ins
There are countless ways to take this base recipe and customize it:
1. Chocolate Chip Peanut Butter Banana Cookies
Add 1/2 cup semi-sweet chocolate chips. A classic combo that adds a melty texture.
2. Banana Oat Peanut Butter Cookies
Stir in 1/2 cup rolled oats for a heartier cookie.
3. Chunky Monkey Style
Add chocolate chips, chopped walnuts, and a dash of cinnamon.
4. Healthy Version
Use oat flour or almond flour, swap sugar for maple syrup or honey, and reduce quantity slightly for the right texture.
5. Vegan Option
Use a flax egg (1 tbsp ground flax + 3 tbsp water, let sit 5 minutes) instead of a real egg.

❄️ Storing & Freezing Tips
Room Temperature
Store in an airtight container for up to 4 days. Keep them soft by placing a slice of bread in the container.
Freezer
To freeze baked cookies: Lay in a single layer on a tray, freeze, then transfer to a freezer-safe bag for up to 3 months.
To freeze dough: Scoop dough balls onto a tray, freeze until firm, and store in a zip-top bag. Bake from frozen—just add 1–2 minutes to baking time.
🎯 Troubleshooting Common Issues
Problem | Cause | Solution |
---|---|---|
Cookies too flat | Too little flour | Add 1–2 tbsp more flour next time |
Cookies dry | Overbaked or too much flour | Check oven temp and reduce bake time |
Cookies not sweet enough | Very ripe bananas used | Add 2 tbsp more sugar or mix in chocolate chips |
Dough too sticky | Warm bananas or peanut butter | Chill dough for 20 mins before scooping |
👪 Perfect for All Ages and Occasions
These cookies are a go-to for:
- Lunchbox treats
- Post-workout snacks
- Holiday cookie trays
- Lazy weekend baking
- Breakfast on-the-go
- Quick desserts for guests
Plus, since they’re slightly healthier than typical cookies (thanks to the fruit and peanut butter), you won’t feel guilty reaching for a second… or third.
