Ingredients You’ll Need

For the brownie batter

• Ripe bananas – the spottier, the better (overripe = flavor jackpot)
• Melted butter – for richness (swap coconut oil if dairy-free)
• Granulated sugar – sweetness + that perfect brownie texture
• Large eggs – structure and binding
• Vanilla extract – makes chocolate taste even more chocolatey
• All-purpose flour – the base
• Baking soda – gives a little lift so they’re not brick-ish
• Salt – balances the sweet
• Cocoa powder – chocolate depth and drama
• Milk – adds moisture (use almond milk if needed)
• Chocolate chips (optional) – for gooey pockets of joy (dark, milk, or white work)
• Brown sugar – adds a caramel-ish warmth
• Ground cinnamon – makes the banana flavor pop

For the topping

• Butter (for topping) – dotted on top before baking for an indulgent finish

How to Make Banana Bread Brownies

1) Preheat and prep the pan

Preheat your oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper. (Parchment is your best friend here—like a friend who helps you move and brings snacks.)

2) Mash those bananas

In a large bowl, mash your ripe bananas until mostly smooth. A few small lumps are fine—this isn’t a smoothie bar.

3) Mix the wet ingredients

To the mashed bananas, stir in:

• melted butter
• granulated sugar
• eggs
• vanilla extract

Mix until it looks creamy and well combined.

4) Whisk the dry ingredients

In a separate bowl, whisk together:

• flour
• baking soda
• salt
• cocoa powder

5) Combine (gently!)

Gradually fold the dry ingredients into the wet banana mixture. Stir just until combined. Overmixing can make brownies tough, and we’re going for “fudgy dream,” not “chocolate workout bar.”

6) Add milk and chocolate chips

Fold in the milk, then stir in chocolate chips if you’re using them. (Highly recommended if you want people to ask, “WHAT is in these??”)

7) Spread the batter

Pour the batter into your prepared pan and spread it evenly with a spatula.

8) Make the topping

In a small bowl, mix brown sugar + cinnamon. Sprinkle it evenly over the batter. Then dot the top with small pieces of butter. This creates a slightly crackly, buttery, cinnamon-sweet layer that tastes like dessert is giving you a standing ovation.

9) Bake

Bake for 25–30 minutes. You’ll know they’re done when a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). That’s the sweet spot for fudgy brownies.

10) Cool and slice

Cool in the pan for about 10 minutes, then move to a wire rack to cool completely before slicing into squares.

I know, waiting is hard. But cutting too early turns them into delicious chaos. (Still tasty… just not as photogenic.)

Aneta’s Little Kitchen Story

These Banana Bread Brownies became my “mom-save” recipe the first time I had bananas on the counter that were one day away from becoming fruit flies’ new condo. I wanted banana bread… but also wanted chocolate… and also didn’t want to wash three extra bowls. So I played around, added cocoa, and topped it with cinnamon sugar like I do when I need comfort food energy.

Now it’s one of those recipes I make when I want my kitchen to smell like a cozy bakery—without actually putting on real pants.

Tips for the Best Banana Bread Brownies

• Use very ripe bananas. If they look a little too far gone, they’re perfect. The darker the spots, the sweeter the batter.
• Don’t overmix once the flour goes in. Stir until you don’t see dry streaks—then stop.
• Cocoa powder matters. If yours is old and smells like cardboard, it might taste like cardboard. (No judgment. We’ve all been there.)
• Want thicker, fudgier squares? Bake closer to 25 minutes and cool fully before slicing.
• Love a stronger cinnamon vibe? Add an extra pinch to the topping. It’s cozy, not complicated.

And if your topping looks a little uneven? Congratulations, you made it homemade. That’s the magic.

Fun Add-Ins and Easy Swaps

• Dairy-free: use coconut oil for the batter and almond milk for the milk.
• Extra chocolate: add chocolate chunks instead of chips.
• Nutty crunch: fold in chopped walnuts or pecans (if your household isn’t in a “nuts are suspicious” phase).
• Swirl moment: dollop a little peanut butter on top and swirl lightly before baking.
