- 1/4 cup honey or maple syrup

Kitchen Equipment Needed

- Fork or potato masher

- 8×8-inch baking pan
- Parchment paper
- Measuring cups and spoons
Step-by-Step Directions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Line an 8×8-inch baking pan with parchment paper or lightly grease it.
Step 2: Mash the Bananas
Place the ripe bananas in a large mixing bowl.
Mash them thoroughly using a fork or potato masher until mostly smooth.
Small lumps are perfectly fine.
Step 3: Add Wet Ingredients
Add the eggs, honey or maple syrup, melted butter, vanilla extract, and milk to the mashed bananas.
Whisk everything together until fully combined.
Step 4: Mix Dry Ingredients
In the same bowl, add:
- Rolled oats
- Cocoa powder
- Baking powder
- Baking soda
- Salt
Stir until no dry streaks remain.
Step 5: Fold in Add-Ins
If using chocolate chips or nuts, gently fold them into the batter.
The batter will be thicker than cake batter but softer than cookie dough.
Step 6: Transfer to Baking Pan
Pour the batter into the prepared baking pan.
Spread evenly using a spatula.
Top with extra chocolate chips or banana slices if desired.
Step 7: Bake
Bake for 28–32 minutes.
The center should be set and a toothpick inserted should come out with a few moist crumbs.
Do not overbake if you want a fudgy brownie texture.
Step 8: Cool Completely
Allow the brownies to cool in the pan for at least 20 minutes.
Cooling helps them firm up and improves texture.
Step 9: Slice and Serve
Cut into squares and serve warm or chilled.
These brownies taste excellent on their own or with a glass of milk or coffee.
