I once tried to impress a friend by bringing a loaf of banana bread to a dinner party and accidentally turned it into brownies by adding more chocolate than sense. Everybody cheered. That happy accident taught me that ripe bananas and fudgy chocolate get along like old friends — loud, warm, and a little messy. These Banana Bread Brownies marry the cozy, cakey banana flavor with a fudgy, crackly brownie top. They smell like caramel and cocoa the moment you open the oven, and they slice into glossy, slightly sticky squares that beg for a napkin and a second helping. Trust me: they disappear faster than I can hide the evidence.

Why This Recipe is Awesome
This recipe gives you the best of both worlds: banana bread’s warm, caramelized banana notes and brownie-level chocolate intensity. You get tender crumb from the bananas and chewy, glossy brownie edges that snap when you lift a square. It’s easy — even your oven can’t mess it up — and it uses pantry staples. Who doesn’t love a dessert that smells like home and looks like a treat?
Ingredients
For the Main Dish:
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 tsp baking powder
- 1/2 tsp fine sea salt
- 1/2 cup unsalted butter, melted and slightly cooled
- 3/4 cup granulated sugar
- 1/4 cup packed brown sugar
- 2 large eggs, room temperature
- 1 tsp pure vanilla extract
- 1 cup mashed ripe bananas (about 2–3 medium bananas)
- 1/2 cup semisweet chocolate chips (plus extra for sprinkling)
- Optional: 1/2 cup chopped walnuts or pecans
For the Sauce / Garnish (if applicable):
- Optional: Vanilla ice cream or whipped cream for serving
- Optional: Flaky sea salt or powdered sugar for dusting
How I Make It
Step 1:
I preheat the oven to 350°F and line an 8-inch square pan with parchment, leaving a little overhang so I can lift the brownies out easily. I mash the fully ripe bananas until they smell sweet and a little fermented — that’s where the flavor lives — and set them aside.
Step 2:
I whisk together the dry ingredients: 1 cup flour, 1/2 cup cocoa, 1 tsp baking powder, and 1/2 tsp salt. The cocoa gives the batter a deep, chocolate-brown color that already makes my kitchen feel decadent.
Step 3:
In a separate bowl, I combine the melted butter, granulated sugar, and brown sugar and whisk until glossy. Then I add the eggs one at a time and stir in vanilla. I fold in the mashed bananas and then gently fold the dry mix in until just combined — little pockets of flour and streaks of cocoa make the texture interesting. Last, I fold in the chocolate chips and nuts if using. The batter should be thick and shiny, smelling like a mix of toasty butter and warm banana.
Step 4:
I spread the batter into the prepared pan and smooth the top with a spatula. I sprinkle a few extra chocolate chips and a pinch of flaky salt on top for drama. I bake for 25–30 minutes, checking at the 20-minute mark. Look for shiny, crackly top and tiny fudgy crumbs clinging to a toothpick — you want it slightly underdone in the center for brownie-like fudginess. The edges should pull away from the pan and feel set.
Step 5:
I cool the pan on a rack for at least 20 minutes — patience pays off here; those squares slice cleaner when the center firms up. I lift the whole slab out using the parchment overhang, cut into 9 squares, and serve warm with a scoop of vanilla ice cream or just a napkin and a cup of coffee. The contrast of warm gooey center and cold ice cream tastes like a hug.
Pro Tips
- Use very ripe bananas (lots of brown spots). They add moisture and deep sweetness without extra sugar.
- If you want fudgier brownies, reduce the flour to 3/4 cup and bake toward the shorter end of the time range.
- Don’t overmix once you add flour. Stir until the streaks disappear — that keeps the texture tender, not gummy.
- Swap half the chocolate chips for dark chocolate chunks for pockets of molten luxury.
Common Mistakes to Avoid
- Skipping preheating: Classic rookie move. It changes texture and bake time.
- Overmixing: Leads to dense or chewy results. Mix until just combined.
- Guessing cook time: Always use visual cues or a timer, not just vibes.
- Overcrowding pans: Give your food some breathing room to crisp properly.
Alternatives & Substitutions
- Replace butter with coconut oil for a dairy-free option (slight coconut flavor). Use 3/4 the amount by volume if the oil is a liquid swap.
- Use a 1:1 gluten-free flour blend to make these gluten-free; texture may turn a touch crumblier.
- Swap granulated sugar for coconut sugar for a deeper caramel note; expect a darker color and slightly drier crumb.
- For vegan brownies, use flax eggs (1 tbsp ground flax + 3 tbsp water per egg) and vegan butter or oil.
Variations & Tips
- Add 1 tsp instant espresso powder to the batter for a richer chocolate flavor — grown-up brownie energy.
- Swirl in 1/4 cup peanut butter into the batter before baking for a PB-banana-chocolate dream.
- Make mini muffins: bake at 350°F for 12–15 minutes in a lined or greased mini muffin tin.
- Mix in shredded coconut for a tropical twist and extra chew.
- Dust with powdered sugar and cocoa for a pretty, simple presentation at parties.
- Turn into bars by pressing a thin layer of dulce de leche between two batches of batter for a caramel surprise.
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Bake the brownies and cool completely, then wrap the slab tightly in plastic and store at room temp for up to 2 days or in the fridge for up to 5 days. Reheat individual squares for 10–15 seconds in the microwave for that fresh-baked warm gooeyness.
- Can I double the recipe?
- Sure thing. Use a 9×13 pan and bake at 350°F, but increase bake time to about 35–40 minutes. Watch for the crackly top and fudgy center rather than relying strictly on minutes.
- Can I substitute butter with oil?
- Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil and expect a slightly denser, less rich texture.
- How do I know it’s done?
- Look for a shiny, crackled top, firm edges, and a center that jiggles slightly but doesn’t look wet. A toothpick should come out with a few fudgy crumbs, not raw batter.
- What if I don’t have ingredient X?
- If you don’t have cocoa powder, substitute with 3 oz melted semisweet chocolate and reduce the butter by 1 tbsp. If you lack brown sugar, use white sugar plus 1 tbsp molasses per 1/4 cup brown sugar needed.
How I Like to Serve It
I love these warm from the oven with a scoop of cold vanilla ice cream and a sprinkle of flaky sea salt. They make a hell of a breakfast with coffee, or pack them for a potluck where they vanish fast. In cooler months, serve with hot cocoa; in summer, add a dollop of whipped cream and fresh berries. They fit every mood: cozy, celebratory, and slightly indulgent.
Notes
- Store leftover brownies in an airtight container at room temperature for up to 2 days or refrigerate up to 5 days. Reheat briefly to restore gooeyness.
- No meat here, so no safe cooking temp needed. Just aim for that fudgy middle and crackly top.
