Ingredients
- For the Banana Bread Bars:
- 1 ¾ cups all-purpose flour, sifted
- 1 teaspoon baking soda
- ½ teaspoon fine sea salt
- ½ teaspoon ground cinnamon
- ½ cup unsalted butter, melted and slightly cooled
- ½ cup light brown sugar, packed
- ¼ cup granulated sugar
- 2 large eggs, at room temperature
- 1 teaspoon pure vanilla extract
- 3 ripe bananas, mashed (about 1 ¼ cups)
- ½ cup sour cream or Greek yogurt
- ½ cup chopped walnuts or pecans (optional)
- For the Brown Butter Frosting:
- 1 stick (½ cup) unsalted butter
- 2 cups powdered sugar, sifted
- 2 tablespoons whole milk or cream, plus extra if needed
- 1 teaspoon pure vanilla extract
- Pinch of fine sea salt
Instructions
- Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, allowing excess sides for easy removal.
- Prepare the dry ingredients: In a medium bowl, whisk together flour, baking soda, salt, and cinnamon. Set aside.
- Mix the wet ingredients: In a large bowl, combine melted butter, brown sugar, and granulated sugar until smooth. Beat in eggs one at a time, then stir in the vanilla extract.
- Incorporate bananas and sour cream: Fold mashed bananas and sour cream gently into the wet mixture without overmixing.
- Combine wet and dry: Gradually add the flour mixture, folding just until you see no dry streaks. Avoid overmixing to keep bars tender. Fold in nuts if using.
- Pour batter into pan: Spread evenly and bake for 28-32 minutes, or until a toothpick inserted near the centre comes out with moist crumbs (not wet batter).
- Cool completely: Allow the bars to cool in the pan on a wire rack for at least 30 minutes before frosting.
- Brown the butter: In a light-colored saucepan over medium heat, melt butter and cook, stirring often, until it foams, turns golden brown, and emits a nutty aroma (about 5 minutes). remove from heat immediately and let cool.
- Prepare the frosting: Whisk cooled browned butter with powdered sugar, milk, vanilla, and salt until smooth. Adjust consistency with more milk or powdered sugar if needed for easy spreading.
- Frost the bars: Spread frosting evenly over cooled banana bread bars. Chill for 15 minutes to set if preferred.
- Cut and serve: Lift parchment and slice into 12 bars. Garnish with additional chopped nuts or banana slices if desired.
Chef’s Notes and Tips for Success
- Banana ripeness matters: Use bananas with dark spots to maximize sweetness and moisture.
- Don’t skip sour cream: It adds tang and moisture,keeping bars tender and preventing dryness.
- Perfect the brown butter: Watch closely to avoid burning-removing from heat as soon as golden nutty notes emerge preserves its flavor.
- Sweetness balance: Brown butter frosting adds richness; reduce powdered sugar slightly if you prefer less sweetness.
- Make-ahead tip: Bars keep well refrigerated for up to 3 days, or freeze un-frosted bars for up to 2 months.
- Variations: Swirl in mini chocolate chips, add shredded coconut, or substitute walnuts with toasted pecans for texture contrast.

A2: Brown butter frosting brings a nutty, caramel-like warmth that complements the sweetness of the bananas perfectly.

The contrast between the smooth, buttery frosting and the hearty banana bars keeps your taste buds engaged and craving more.
Q3: Can I substitute the brown butter frosting with something lighter?

Just fold your chosen mix-ins into the batter gently to prevent overmixing, and adjust baking time slightly if needed. The brown butter frosting pairs especially well with nutty additions, enhancing the overall decadence.
Q7: How do I brown butter properly for the frosting?
