Ingredients:

Banana Bread Bars:

• 1/2 cup (110g) unsalted butter
• 1 cup (200g) granulated sugar
• 1/2 cup (105g) light brown sugar, packed
• 2 large eggs
• 1 cup (250g) sour cream
• 1 1/2 cups (385g) ripe bananas, mashed (about 4 medium bananas)
• 1 tsp vanilla extract
• 1 tsp baking soda
• 1/2 tsp kosher salt
• 2 cups (265g) all-purpose flour

Brown Butter Frosting:

• 3/4 cup (170g) unsalted butter (+ 2 tbsp chilled)
• 3 cups (300g) powdered sugar
• 1 tsp vanilla extract
• 1/4 cup (60g) milk, room temperature

Method:

1. Preparation:
   • Preheat your oven to 350°F (175°C). Grease an 11×15-inch jelly roll pan.
2. Brown the Butter:
   • In a saucepan, melt 1 1/4 cups of butter over medium heat until it becomes foamy and turns a light amber color. This will be used for both the bars and the frosting.
3. Divide the Brown Butter:
   • Measure out 1/2 cup of the browned butter for the bars and set aside. Pour the remaining brown butter into a mixing bowl, adding the extra 2 tablespoons of chilled butter to melt.
4. Chill for Frosting:
   • Place the mixing bowl with the majority of the brown butter into the refrigerator to solidify for the frosting.
5. Make the Banana Bread Bar Batter:
   • In a separate mixing bowl, combine the 1/2 cup of reserved brown butter, granulated sugar, and brown sugar. Whisk in the eggs, sour cream, mashed bananas, and vanilla.
   • Add baking soda and salt, then gradually mix in the flour until just combined.
   • Spread the batter evenly in the prepared pan.
6. Bake:
   • Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Allow to cool.
7. Prepare the Frosting:
   • Once the brown butter has solidified but is still soft, use a mixer to gradually incorporate the powdered sugar, followed by the vanilla and milk, until smooth and creamy.
8. Frost and Finish:
   • Spread the frosting over the cooled bars. Allow the frosted bars to set at room temperature for about 30 minutes before slicing.

Enjoy these luxurious Brown Butter Banana Bread Bars, a delectable treat that combines classic comfort with a touch of gourmet sophistication!
