How to Make Banana Bars with Brown Butter Icing
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Line an 8×8 baking dish with parchment paper, allowing the edges to hang over the sides for easy removal later.
Step 2: Mix Wet Ingredients
In a large mixing bowl:
1. Beat together ¾ cup sugar, ½ cup sour cream, ¼ cup softened butter, and 1 egg until creamy.
2. Blend in the mashed bananas and 1 tsp. vanilla extract.
Step 3: Combine Dry Ingredients
Add in:
– 1 cup all-purpose flour

Stir together until just combined.
Step 4: Bake
Spread the batter evenly into your prepared pan. Bake for 20 to 25 minutes or until golden brown. Let cool slightly before using the parchment paper to lift them from the pan.
Step 5: Prepare Brown Butter
In a medium saucepan:
1. Melt the remaining butter over medium-high heat.
2. Continue cooking until brown bits form at the bottom of the pan; swirl occasionally but do not let it burn.
Step 6: Make Icing
Pour the browned butter into a heat-proof bowl:
1. Whisk in 2 cups powdered sugar, 1 tsp. vanilla extract, and 1½ tbsp. milk. Mix until smooth.
