Introduction (Short)
Banana Cake Bars with Browned Butter Glaze are the perfect solution for overripe bananas. Soft, moist, and slightly dense, these bars strike a balance between fluffy cake and classic banana bread. The rich browned butter glaze adds a deep, nutty sweetness that sets into a smooth, fudge-like finish.
Ingredients
The Cake Bars:
1/2 cup (115g) unsalted butter, melted and slightly cooled
1 cup granulated sugar
1 large egg, room temperature
1 teaspoon pure vanilla extract
1 1/2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1 1/2 cups mashed overripe bananas (about 3 large bananas)
1/2 cup chopped walnuts or pecans (optional)
The Browned Butter Glaze:
1/2 cup unsalted butter
2 cups powdered sugar, sifted
1 1/2 teaspoons vanilla extract
2–3 tablespoons milk or heavy cream
Instructions
Preheat your oven to 175°C (350°F) and grease a 9×13 inch baking pan or line it with parchment paper.
Whisk together the melted butter and sugar until fully combined.
Add the egg and vanilla extract, mixing until smooth and slightly pale.
In a separate bowl, whisk together flour, baking soda, and salt.
Gradually stir the dry ingredients into the wet mixture, alternating with the mashed bananas.
Fold in the chopped nuts if using.
Spread the batter evenly into the prepared pan.
Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
Allow the bars to cool for at least 15 minutes before glazing.
How to Make (The Glaze)
Place the butter in a saucepan over medium heat.
Whisk constantly as it melts, foams, and begins to form golden-brown specks.
Once it smells nutty and turns amber in color, remove immediately from heat.
Whisk in powdered sugar, vanilla extract, and milk one tablespoon at a time.
Mix until smooth and thick but pourable.
Pour the warm glaze over the slightly warm bars and spread quickly with a spatula.
Let it set before slicing.
Variations
Chocolate Chip: Add 1/2 cup semi-sweet chocolate chips to the batter.
Spiced: Mix 1 teaspoon cinnamon and 1/4 teaspoon nutmeg into the flour mixture.
Cream Cheese Swirl: Swirl sweetened cream cheese into the batter before baking.
Salted Caramel: Sprinkle a pinch of sea salt over the glaze while still wet.
Tips
Use very ripe bananas with dark spots for maximum sweetness and moisture.
Avoid overmixing once the flour is added to keep the texture soft.
Monitor the butter closely while browning; it can burn quickly.
Always sift powdered sugar for a silky-smooth glaze.
Let the glaze set fully before cutting for clean slices.
