Frosted Banana Bars Ingredients:

Here’s what you need to make easy frosted banana bars with brown butter frosting:

Ripe Bananas: The star of the show, bananas provide natural sweetness and moisture. Ensure your bananas are overripe (brown spots on the peel) for the best flavor.

Butter: Adds richness and moisture.

Granulated Sugar: Provides sweetness.

Brown Sugar: Adds a deeper flavor and moisture due to its molasses content.

Eggs: Bind the ingredients together and add structure.

Vanilla Extract: Adds flavor depth.

Buttermilk: Contributes to the moistness and tenderness of the bars.

All-Purpose Flour: Gives structure to the bars.

Baking Soda and Baking Powder: Helps the bars rise and become fluffy.

Salt: Enhances the overall flavor.

Brown Butter Frosting Ingredients:

This is a special brown butter cream cheese frosting recipe that pairs the toffee notes from brown butter with the creamy, tangy flavor of cream cheese and the sweetness of powdered sugar.

• Butter: The key is taking the time to brown the butter to create toffee, nutty notes in the butter.
• Cream Cheese: This adds a rich, tangy, creamy texture that cuts the sweetness of the sugar to make it perfectly sweet.
• Powdered Sugar: This adds the sweetness to the frosting. If you desire a thicker frosting, add up to 1/4-1/2 cup more powdered sugar.
• Vanilla Bean Paste or Vanilla Extract: For the best vanilla flavor, I suggest using vanilla bean paste but a high-quality vanilla extract will be delicious as well.

How to make the Best Banana Bars:

• Add eggs one at a time, mixing in between. Stir in vanilla.
• In a small bowl, mash bananas with lemon juice. Add bananas to bowl and mix well. Stir in buttermilk.
• Add flour, baking soda, baking powder, and salt. Pour into greased 9 x 13 pan.
• Bake for 70-75 minutes or until baked in the middle.
• Place in freezer for 45 minutes to 1 hour to keep moist (put oven mitts underneath pan).
• While it is cooling, make the brown butter frosting. Start by browning the butter in a saucepan and then removing from the heat. Place the brown butter in a mixing bowl. Once it has cooled for about 20 minutes, add the cream cheese, powdered sugar, and vanilla, and beat until light and fluffy.
• Frost the chilled banana bars with the brown butter cream cheese frosting.

How do I know when Banana Bars are Done?

The banana bars are done when a toothpick inserted into the center comes out clean or with just a few moist crumbs. This ensures the bars are baked through but still moist. Overbaking can lead to dry bars, so it’s important to start checking a few minutes before the suggested baking time.
