Fudgy Banana Brownies

These Banana Fudge Brownies are deeply chocolatey, dense, and wonderfully fudgy, with just enough ripe banana to add natural sweetness and a soft, tender texture. The melted chocolate gives the brownies a glossy, rich center, while brown sugar adds a subtle caramel note and the chocolate chips create little pockets of melted chocolate throughout.

The best part is how simple they are to make. There is no mixer required, and the batter comes together in one bowl with everyday ingredients. I especially like this recipe for using up those bananas that have gone far past the stage where anyone wants to eat them plain. My kids always seem to find these brownies before they have fully cooled, but chilling them briefly makes the texture even denser and easier to slice.

For the fudgiest results, use very ripe, heavily spotted bananas, measure the flour carefully, and stop folding as soon as the dry ingredients disappear. The center should still look slightly soft when the brownies come out of the oven; they will continue setting as they cool.

Ingredients

Banana Brownies

• 2 medium very ripe bananas, mashed
• ½ cup unsalted butter, melted
• ¾ cup packed brown sugar
• ¼ cup granulated sugar
• 2 large eggs
• 1 tsp vanilla extract
• 4¼ oz dark or semi-sweet chocolate, melted
• ¾ cup all-purpose flour
• ⅓ cup + 1 tbsp unsweetened cocoa powder
• ½ tsp salt
• ⅔ cup chocolate chips or chopped chocolate, plus extra for topping

Instructions

1. Prepare the pan. Heat the oven to 175°C / 350°F. Line an 8-inch square baking pan with parchment paper, leaving enough overhang to lift out the finished brownies.
2. Mix the wet ingredients. Mash the bananas in a large bowl until nearly smooth. Add the melted butter, brown sugar, granulated sugar, eggs, and vanilla. Whisk until smooth and well combined.
3. Add the melted chocolate. Pour in the melted chocolate and whisk until the batter is dark, glossy, and evenly mixed.
4. Add the dry ingredients. Sift the flour, cocoa powder, and salt into the bowl. Fold gently with a spatula just until no dry streaks remain. Do not overmix.
5. Fold in the chocolate chips. Add most of the chocolate chips or chunks, reserving some for the top. Fold just enough to distribute them throughout the batter.
6. Fill the pan. Spread the batter evenly into the prepared pan. Scatter the reserved chocolate chips or chunks over the surface.
7. Bake. Bake at 175°C / 350°F for 25–30 minutes. The top should be set and slightly crackly, while the center should remain soft and fudgy. A toothpick inserted near the center should come out with moist crumbs rather than completely clean.
8. Cool and slice. Let the brownies cool completely in the pan. For especially dense, clean-cut brownies, refrigerate them for about 30 minutes before slicing into 16 squares.

Cooking Notes

Use very ripe bananas: Heavily spotted bananas provide the most concentrated banana flavor and sweetness.

Do not overdo the banana: Adding extra banana may seem tempting, but the additional moisture can make the brownies too soft or shift the texture toward cakey.

Do not overmix: Once the flour and cocoa are added, fold only until combined. Excess mixing can make the brownies less tender.

Watch the center: A completely clean toothpick usually means the brownies have been baked too long. Moist crumbs are the goal for a fudgy center.

For cleaner slices: Chill the fully cooled brownies for about 30 minutes, then use a sharp knife and wipe it clean between cuts.

Chocolate choice: Dark chocolate creates a deeper flavor, while semi-sweet chocolate gives a sweeter, more classic brownie profile.

FAQ

• Can I use less-ripe bananas? Yes, but very ripe bananas are strongly recommended because they provide more sweetness, moisture, and banana flavor.
• Why are my brownies too soft? They may need more cooling time. These brownies are intentionally fudgy, and their texture firms considerably as they cool. Refrigerating them for 30 minutes can also help.
• Can I use milk chocolate? Yes. Keep in mind that milk chocolate will make the brownies sweeter and less intensely chocolatey than dark or semi-sweet chocolate.
• Can I freeze the brownies? Yes. Cool them completely, cut into squares, wrap individually, and freeze in an airtight container. Thaw at room temperature before serving.
• Why did my brownies turn cakey? Too much flour, overmixing, or overbaking can all make brownies cakier. Measure the flour carefully, fold gently, and remove the brownies while the center still gives moist crumbs on a toothpick.
