- Transfer to baking pan: Pour the mixture into the prepared baking pan and spread it evenly using a spatula.
- Bake: Place the pan in the oven and bake for 20 minutes or until the edges turn golden and the bars are set.
- Cool and slice: Let the bars cool completely in the pan before slicing them into 9 squares. Enjoy!

Notes
- Banana ripeness: Make sure your bananas are very ripe (spotted brown) for maximum sweetness.
- Add-ins: For extra texture, feel free to fold in some chocolate chips, chopped nuts, or dried fruit.
- Storage: Store these bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to 1 week.
