Banana bars with brown butter frosting -the best way to use ripe bananas! These bars are super soft and are always a hit at potlucks. They never last long!

Whenever I spot a bunch of brown bananas at the store, or end up with some on my counter, I know exactly what I want to make…frosted banana bars. As much as I love banana bread (especially with chocolate chips), these bars are always on my mind.

MY OTHER RECIPES

The only problem with these bars is they make a lot, so I have to find a place to take them or I will eat the entire pan! You can definitely cut this recipe in half and bake them in a 9×9 bar, but I love to make the whole sheet.

For this recipe I made brown butter frosting to top them with(which is truly divine), but with my original recipe I use a cream cheese frosting, so you can definitely use that as well. Here’s a good recipe for cream cheese frosting. If you’re looking for tips on how to brown butter, make sure to check out this post here.

We don’t usually top the bars with bananas (unless serving immediately), but I thought it would be pretty for the photo :)

Banana bars with brown butter frosting

Yield: 28-35 bars

Prep Time: 20 minutes

Cook Time: 20-25 minutes

Total Time: 45 minutes

Ingredients:

For the bars:

  • 1/2 cup unsalted butter, at room temperature, plus more from the pan
  • 1 cup granulated sugar
  • 1/2 cup light brown sugar
  • 2 large eggs
  • 1 cup sour cream
  • 1 1/2 teaspoons vanilla extract
  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking soda
  •  1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  •  1/2 teaspoon ground cinnamon
  • 2 cups mashed ripe bananas (5 brown bananas)

Brown butter frosting:

  • 1/2 cup unsalted butter
  • 3 1/2 -4 cups powdered sugar
  • 3-4 Tablespoons milk
  • 2 teaspoons pure vanilla extract
  • pinch of salt

Directions:

Preheat the oven to 350°F. Butter a large rimmed baking sheet (12x18"). In a large bowl, cream together the butter, sugar and brown sugar. Add the eggs, sour cream and vanilla. Mix just until combined.

In a seperate bowl whisk together the flour, baking soda, baking powder, salt and cinnamon. Slowly add the flour mixture into the other bowl and stir just until smooth. Fold in the mashed bananas and then pour into the baking sheet.

Bake for 20 - 25 minutes or until a toothpick comes clean and the top is golden. Remove from oven and allow the bars to cool completely.

For the brown butter frosting, melt the butter in a large sauce pan over medium heat. Cook for about 3-4 minutes, until the butter has turned a golden brown and has a nutty aroma. As soon as you notice the color change, quickly remove the pan from heat to prevent it from burning.

Whisk in the powdered sugar, milk and the vanilla. Pour immediately over the bars and spread evenly with a spatula. Move quickly, as the frosting will thicken fast. Cover until ready to serve.
