Ingredients You’ll Need
Here’s everything required to make these irresistible Banana Bread Brownies. All measurements are provided in both US and metric units for convenience.
3 medium ripe bananas (about 1½ cups mashed / 360 g mashed)
½ cup unsalted butter, melted (115 g)
1 cup granulated sugar (200 g)
½ cup brown sugar, packed (100 g)
2 large eggs
1 teaspoon vanilla extract (5 ml)
1½ cups all-purpose flour (190 g)
1 teaspoon baking powder (5 g)
½ teaspoon baking soda (3 g)
½ teaspoon salt (3 g)
½ teaspoon ground cinnamon (optional)
½ cup chopped walnuts or chocolate chips (optional, 90 g)
Optional Glaze:
1 cup powdered sugar (120 g)
2–3 tablespoons milk (30–45 ml)
½ teaspoon vanilla extract (2 ml)
Step-by-Step Instructions
1. Prepare the Pan
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan (23×33 cm) with parchment paper or lightly grease it with butter or non-stick spray.
2. Mash the Bananas
In a large mixing bowl, mash the ripe bananas until smooth. A few small lumps are fine, but aim for a mostly creamy consistency.
3. Mix the Wet Ingredients
Add the melted butter to the mashed bananas and stir well. Mix in the granulated sugar and brown sugar until combined. Add the eggs one at a time, beating gently after each addition. Stir in the vanilla extract.
4. Combine the Dry Ingredients
In a separate bowl, whisk together the flour (190 g), baking powder (5 g), baking soda (3 g), salt (3 g), and cinnamon if using.
Gradually fold the dry ingredients into the wet mixture. Stir until just combined. Do not overmix, as this can make the bars dense.
5. Add Mix-Ins
If using walnuts or chocolate chips (90 g), gently fold them into the batter.
6. Bake
Pour the batter evenly into the prepared pan. Smooth the top with a spatula.
Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
7. Cool and Glaze
Allow the bars to cool completely in the pan before adding glaze.
To make the glaze, whisk together powdered sugar (120 g), milk (30–45 ml), and vanilla (2 ml) until smooth. Drizzle over the cooled brownies and let it set before slicing.
Tips for Perfect Banana Bread Brownies
Use Very Ripe Bananas
The darker and softer the bananas, the sweeter and more flavorful your brownies will be. Bananas with brown spots are ideal.
Don’t Overmix
Overmixing develops gluten and can lead to tough bars. Stir until ingredients are just combined.
Check for Doneness Early
Ovens vary, so start checking around 25 minutes. Overbaking can dry out the brownies.
Let Them Cool Completely
Cooling helps the bars set properly and makes slicing much easier.
Variations to Try
Chocolate Swirl
Add ¼ cup (60 g) melted chocolate and swirl it into the batter before baking for a marbled effect.
Cream Cheese Frosting
Top with a simple cream cheese frosting instead of glaze for a richer dessert.
Nut-Free Option
Simply skip the walnuts if serving to someone with nut allergies.
Add a Crunchy Topping
Sprinkle chopped nuts or streusel topping over the batter before baking for added texture.
How to Store Banana Bread Brownies
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to 5 days.
You can also freeze them by wrapping individual bars tightly in plastic wrap and placing them in a freezer-safe bag. Freeze for up to 3 months. Thaw at room temperature before serving.
Frequently Asked Questions
1. Can I use frozen bananas?
Yes, frozen bananas work very well in this recipe. Simply thaw them completely and drain off any excess liquid before mashing. Frozen bananas often become even sweeter as they thaw, which enhances the flavor of the brownies. Just make sure they are at room temperature before mixing with the butter to avoid solidifying it.
2. Why are my banana bread brownies too dense?
Density usually happens due to overmixing or using too much flour. Make sure to measure your flour correctly by spooning it into the measuring cup and leveling it off rather than scooping directly from the bag. Also, mix only until the flour is incorporated. Another reason could be under-ripe bananas, which lack moisture and natural sweetness.
3. Can I make these gluten-free?
Yes, you can substitute the all-purpose flour with a 1:1 gluten-free baking flour blend (190 g). Look for one that contains xanthan gum for better structure. The texture may be slightly different, but they will still be moist and flavorful. Let them cool completely before slicing, as gluten-free baked goods can be softer when warm.
4. Can I reduce the sugar?
You can reduce the total sugar by about ¼ cup (50 g) without significantly affecting texture. However, keep in mind that sugar contributes not only sweetness but also moisture and structure. If you reduce it too much, the bars may turn out drier. Using very ripe bananas helps maintain sweetness even with slightly less sugar.
