👩🍳 Step-by-Step Instructions
Follow these simple steps for the best results:
1. Preheat & Prepare
Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
2. Mix the Dough
In a large bowl, mash the bananas until smooth. Add the brownie mix, egg, and melted butter (or oil). Stir until fully combined.
3. Fold in Add-Ins
Gently fold in chocolate chips, nuts, or other mix-ins of your choice.
4. Scoop & Bake
Drop spoonfuls of dough (about 1½ tablespoons each) onto the prepared baking sheet, leaving 2 inches between cookies. Bake for 10–12 minutes, until edges are set and tops look slightly cracked.
5. Cool & Serve
Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. Enjoy warm or store for later!
🔧 Expert Baking Tips
- Use Very Ripe Bananas: The spottier, the better—they add sweetness and moisture.
- Don’t Overbake: Remove when the edges are set but centers are soft. They’ll firm up as they cool.
- Customize the Texture:
- Want fudgier cookies? Add an extra ½ banana.
- Prefer cakier cookies? Add one more egg.
- Freeze Dough for Later: Scoop dough onto a tray, freeze, then store in a bag. Bake straight from frozen with 2 extra minutes of bake time.
📦 Storage & Freezing
- Room Temperature: Store in an airtight container for up to 3 days.
- Refrigerator: Keeps fresh for 5–6 days.
- Freezer: Freeze cookies (or raw dough balls) for up to 2 months. Reheat baked cookies in the microwave for 10–15 seconds.
🍴 Serving Ideas
- Serve warm with a scoop of vanilla ice cream.
- Make cookie sandwiches with peanut butter or cream cheese frosting.
- Pair with a glass of milk or hot coffee for a cozy snack.

❓ Frequently Asked Questions (FAQs)
1. Can I use cake mix instead of brownie mix?
Yes, but the texture will be lighter and more cake-like. Brownie mix gives the best fudgy results.
2. Do I have to use an egg?
No—substitute with a flax egg or ¼ cup applesauce for an egg-free version.
3. How do I know when the cookies are done?
When edges are firm and the tops have cracks. Don’t wait for them to be fully set in the middle.
4. Can I add peanut butter?
Yes! Swirl 2–3 tablespoons into the dough before baking, or drizzle on top after baking.
