These banana bread brownies transform two classic desserts into one irresistible treat that satisfies both banana bread lovers and chocolate enthusiasts. The rich cocoa flavor combined with sweet, ripe bananas creates a moist, fudgy dessert that's impossible to resist.

I first made these brownies when I couldn't decide between banana bread and brownies for a family gathering. The combination was such a hit that my nieces and nephews now specifically request "those banana chocolate squares" at every holiday.

Ingredients

  • Ripe bananas: Provide natural sweetness and moisture making these brownies incredibly soft
  • Unsalted butter: Adds richness and allows you to control the salt content
  • Brown sugar: Creates depth of flavor with its molasses notes
  • Granulated sugar: Balances the sweetness and helps with texture
  • Large eggs: Provide structure and bind everything together
  • Vanilla extract: Enhances both the chocolate and banana flavors
  • All-purpose flour: Gives the perfect foundation without being too heavy
  • Cocoa powder: Delivers that intense chocolate flavor we all crave
  • Baking soda: Helps the brownies rise just enough without being cakey
  • Salt: Enhances all flavors and balances the sweetness
  • Optional walnuts or pecans: Add delightful crunch and nutty flavor
  • Optional chocolate chips: Create pockets of melty chocolate throughout

Step-by-Step Instructions

Preheat and Prepare:
Heat your oven to 350°F and prepare your baking pan with both grease and parchment. The parchment creates handles that make removing the brownies incredibly easy after baking. Make sure the parchment hangs over at least two sides of the pan.
Banana Butter Mixture:
Thoroughly mash the bananas until almost no lumps remain then blend with melted butter. Use bananas with plenty of brown spots for the best flavor. The butter should be melted but not hot enough to cook the eggs when added later.
Sugar Incorporation:
Mix both sugars into your banana mixture until fully dissolved. This creates the foundation of sweetness and ensures even distribution. The brown sugar adds moisture while the granulated sugar helps create that slight crinkly top.
Add Eggs and Vanilla:
Incorporate eggs one at a time, allowing each to fully blend before adding the next. This creates a smoother emulsion. Then mix in vanilla extract, which complements both the banana and chocolate flavors beautifully.
Dry Ingredient Preparation:
Whisk your flour, cocoa powder, baking soda, and salt in a separate bowl. This prevents clumps and ensures even distribution of the leavening agent. Sift the cocoa powder if it has lumps for the smoothest texture.
Combine Mixtures:
Gently fold the dry ingredients into the wet until just combined. Stop mixing as soon as no dry streaks remain to avoid developing too much gluten, which would make the brownies tough rather than tender.
Add Optional Mix-ins:
If using nuts or chocolate chips, fold them in with just a few strokes. Coating them lightly in flour before adding can help prevent them from sinking to the bottom during baking.
Transfer to Pan:
Pour the thick batter into your prepared pan and spread evenly with a spatula. Tap the pan gently on the counter a few times to release any air bubbles trapped in the batter.

The secret to these brownies is truly in the bananas. I found that using bananas that are heavily speckled but not completely black gives just the right amount of sweetness and banana flavor without overwhelming the chocolate. My grandmother taught me this trick years ago when making her famous banana bread.

Perfect Ripeness

Finding the ideal banana ripeness makes all the difference in this recipe. Look for bananas with plenty of brown spots on the peel. Yellow bananas with minimal spots will lack sweetness and flavor, while completely black bananas might overpower the chocolate elements. The perfect banana for this recipe should be soft to the touch but not mushy.

Storage Solutions

These brownies maintain their moisture beautifully for several days. Store them in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. Place parchment paper between layers to prevent sticking. For longer storage, wrap individual brownies tightly in plastic wrap and freeze for up to 3 months. Thaw at room temperature for an hour before enjoying.

Serving Suggestions

While these brownies are delicious on their own, they transform into an extraordinary dessert when served warm with a scoop of vanilla ice cream. The contrast between the warm, fudgy brownie and cold, creamy ice cream creates a memorable taste experience. For special occasions, drizzle with caramel sauce or add a dollop of whipped cream and a few banana slices on top.

Frequently Asked Questions

→ How do I know when my banana bread brownies are done baking?

Your banana bread brownies are done when a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). This typically takes 25-30 minutes at 350°F. Be careful not to overbake, as you want to maintain that fudgy texture. The edges should be set but the center can still be slightly soft.

→ Can I use overripe bananas for this dessert?

Overripe bananas are actually ideal for this dessert! The browner and spottier your bananas, the sweeter and more flavorful your brownies will be. Very ripe bananas are easier to mash and incorporate into the batter, plus they provide more natural sweetness and stronger banana flavor.

→ Are nuts necessary in this recipe?

Nuts are completely optional in this recipe. While they add a delightful texture contrast and nutty flavor, the brownies will still be delicious without them. If you choose to include nuts, both walnuts and pecans work wonderfully, but you can also experiment with other varieties like almonds or hazelnuts.

→ How should I store leftover banana bread brownies?

Store leftover banana bread brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week (though this may slightly affect the texture). You can also freeze them by wrapping individual portions in plastic wrap and then aluminum foil; they'll keep for up to 3 months in the freezer.

→ Can I make these brownies dairy-free?

Yes, you can make these brownies dairy-free by substituting the unsalted butter with the same amount of coconut oil or a plant-based butter alternative. For the optional chocolate chips, use dairy-free dark chocolate chips. The rest of the ingredients are naturally dairy-free, making this an easy recipe to adapt.

→ What can I add to enhance the flavor of these brownies?

To enhance the flavor, consider adding 1/2 teaspoon of cinnamon, a pinch of nutmeg, or 1/4 teaspoon of espresso powder to the dry ingredients. You could also drizzle the cooled brownies with a simple glaze made from powdered sugar and milk, or swirl peanut butter into the batter before baking. For adults, a tablespoon of dark rum or bourbon adds wonderful depth.

Instructions

Step 01

Preheat oven to 175°C (350°F). Grease and line an 8x8-inch baking pan with parchment paper.

Step 02

In a large mixing bowl, combine the mashed bananas and melted butter. Whisk until smooth. Add both brown and granulated sugars, mixing until well combined.

Step 08

Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

Use the parchment paper to lift the brownies out of the pan. Allow to cool completely on a wire rack before slicing.

Notes

  1. For extra flavor, toast the nuts before adding them to the batter.
