For those who follow me on Instagram, you may have seen my post about some bars—these are not the same, but they’re delicious nonetheless. That other recipe should be coming next week.
Do you have ripe bananas and need a great way to use them? Try these banana bars. My sister has been making this recipe for about a year; it originates from The Girl Who Ate Everything. She’s not a chocolate person and often brings these when she’s in charge of dessert. They are wonderful.
The brown butter frosting complements the banana flavor perfectly. This recipe has the familiar taste of banana bread but is more cake-like and baked as bars. You should give them a try—you won’t regret it.

Banana Bars with Brown Butter Frosting
Recipe Type: Dessert
Author: Nikki
These bars are soft and delicious—the perfect way to use up ripe bananas.
Ingredients
- 1 1/2 cups sugar
- 1 cup sour cream
- 1/2 cup butter, softened
- 2 eggs
- 3–4 ripe bananas, mashed
- 2 teaspoons vanilla
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 3/4 teaspoon salt
- Brown Butter Frosting
- 1/2 cup butter
- 4 cups powdered sugar
- 1 1/2 teaspoons vanilla
- 3 tablespoons milk, more if needed to reach desired consistency
Instructions
- Preheat oven to 375°F (190°C).
- Grease and flour a 15 by 10-inch jelly roll pan.
- In a large bowl, beat together the sugar, sour cream, softened butter, and eggs until creamy. Stir in the mashed bananas and vanilla. Add the flour, baking soda, and salt; mix until just combined. Spread the batter evenly in the prepared pan and bake 20–25 minutes, or until the top is golden and a toothpick inserted near the center comes out clean.
Frosting
- Make the frosting while the bars are baking. In a medium saucepan over medium heat, melt the butter and bring it to a gentle boil. Continue cooking until the butter turns a light golden brown and develops a nutty aroma, watching carefully to avoid burning. Remove from heat and let cool slightly.
- Whisk in the powdered sugar, vanilla, and milk until smooth. The consistency should be thicker than a glaze but thinner than traditional frosting; add a little more milk if needed.
- Spread the frosting over the warm bars using a spatula. Allow the bars to cool completely so the frosting sets before cutting into squares.
