Ingredients:
For the Banana Bread Bars:
- 1½ cups granulated sugar
- 1 cup plain Greek yogurt (or sour cream)
- ½ cup butter, softened
- 2 large eggs
- 3-4 ripe bananas, mashed
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- ¾ teaspoon salt
For the Brown Butter Frosting:
- 4 tablespoons butter
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
- 1-2 tablespoons milk
Directions:
- Prepare Your Workspace: Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking pan with non-stick cooking spray.
- Create the Base Mixture: In a large bowl, cream together the sugar and softened butter until light and fluffy. Beat in the Greek yogurt, eggs, mashed bananas, and vanilla extract until well combined.
- Incorporate Dry Ingredients: Add the flour, baking soda, and salt to the wet ingredients. Mix gently until just combined, being careful not to overmix.
- Bake to Perfection: Spread the batter evenly in your prepared pan. Bake for 23-28 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.
- Prepare the Brown Butter Frosting: While the bars bake, heat the butter in a skillet over medium heat. Cook until it turns golden brown and develops a nutty aroma, stirring constantly. Remove from heat immediately.
- Finish the Frosting: Whisk the browned butter with powdered sugar, vanilla extract, and milk until smooth. Add more milk or sugar as needed to achieve your desired consistency.
- Add the Final Touch: Pour the warm frosting over the warm bars, spreading it gently with the back of a spoon for an even layer.
