Step 1: Prepare the Baking Dish and Preheat Oven
- Preheat your oven to 350°F (175°C).
- Grease and line a 9×13-inch baking pan with parchment paper for easy removal.
Step 2: Make the Batter
- In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
- Beat in the eggs one at a time, followed by the vanilla extract.
- Add the mashed bananas and sour cream (or Greek yogurt) and mix until smooth.
Step 3: Combine Dry Ingredients
- In a separate bowl, whisk together the flour, baking soda, and salt.
- Gradually add the dry ingredients to the wet mixture, mixing until just combined.
- Fold in the walnuts or chocolate chips, if using.
Step 4: Bake
- Pour the batter into the prepared baking pan and spread it evenly.
- Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
- Allow the brownies to cool in the pan while you prepare the glaze.
Step 5: Make the Browned Butter Glaze
- In a small saucepan, melt the butter over medium heat until it turns golden brown and has a nutty aroma. Be careful not to burn it.
- Remove the butter from the heat and whisk in the powdered sugar, vanilla extract, and milk until smooth and pourable.
Step 6: Glaze the Brownies
- Pour the glaze over the warm brownies, spreading it evenly with a spatula.
- Let the glaze set for at least 15 minutes before slicing into squares.
Serving Suggestions
- Serve warm with a scoop of vanilla ice cream for a decadent dessert.
- Pair with a hot cup of coffee or tea for a comforting snack.
Tips for Success
- Ripe Bananas: The riper the bananas, the sweeter and more flavorful the brownies will be.
- Don’t Overmix: Mix the batter just until combined to avoid dense brownies.
- Glaze Consistency: Adjust the milk in the glaze for your desired thickness.
Variations
- Peanut Butter Drizzle: Add a drizzle of melted peanut butter over the glaze for a nutty twist.
- Spiced Brownies: Add a pinch of cinnamon or nutmeg to the batter for a warm, spiced flavor.
- Vegan Option: Replace eggs with flaxseed eggs, butter with plant-based alternatives, and sour cream with coconut yogurt.
Why This Recipe Works
The combination of creamy bananas, buttery richness, and the soft texture of brownies creates a dessert that’s both familiar and extraordinary. The browned butter glaze adds a caramel-like depth that takes these brownies over the top.
