- 1 tsp Vanilla extract
- The “Banana” Core:
- 3 large Overripe bananas (mashed—approx. 1 ½ cups)
- The Structure:
- 2 cups All-purpose flour

👩🍳 Instructions
1. The Butter Browning
- In a small saucepan over medium heat, melt the butter. Continue cooking, swirling the pan, until it turns a deep amber color and smells nutty. The Pro Move: Immediately pour it into a bowl (bits and all) to stop the cooking. Let it cool for 5 minutes.
2. The Creaming
- Preheat your oven to 175°C (350°F). Grease a 9×13 inch baking pan.
- Beat the browned butter and sugar for 2 minutes. Add the sour cream, eggs, vanilla, and mashed bananas.
3. The Gentle Fold
- Whisk the flour, baking soda, and salt.
- Gradually add the dry ingredients to the banana mixture. The Texture Rule: Stir until just combined. If you over-beat the batter, your “bars” will become “bread” (tough and bready).
4. The Sheet Bake
- Spread the batter into the prepared pan. Bake for 25–30 minutes.
- The Visual Cue: The edges should be pulling away slightly from the sides and a toothpick should come out clean. Crucial: Let these cool completely before frosting.
5. The Brown Butter Frosting
- Brown the remaining ½ cup of butter. Beat it with the cream cheese, powdered sugar, and vanilla until whipped and airy.
- Spread a thick layer over the cooled bars.
The “Nutty” Upgrade: If you are a fan of texture, sprinkle ½ cup of toasted walnuts over the frosting. The bitterness of the walnuts perfectly complements the sweet, jammy banana base.
