How To Make Banana Bread Brownies
Baking the perfect batch of Banana Bread Brownies is an enjoyable and rewarding process. Here’s a detailed guide to help you achieve the best results:
- Step 1: Prep Work: Start by preheating your oven and greasing your baking pan. This ensures a smooth release of the brownies after baking and an even cooking temperature from the start.
- Step 2: Mixing Wet Ingredients: Using an electric mixer, blend the sugar, sour cream, butter, and eggs until creamy. This step is crucial for dissolving the sugar and incorporating air into the batter, which helps achieve a light texture.
- Step 3: Adding Flavor: Introduce the mashed bananas and vanilla extract to the mixture. The bananas should be well-ripened for maximum flavor and sweetness, enhancing the overall taste of the brownies.
- Step 4: Combining Dry Ingredients: Gradually mix in the flour, baking soda, and salt. It’s important to mix these ingredients until just combined to avoid overworking the batter, which can make the brownies tough.
- Step 5: Adding Extras: Fold in the chopped walnuts for a nutty flavor and a bit of crunch. This adds a delightful texture contrast to the moist, soft brownies.
- Step 6: Baking: Pour the batter into the prepared pan and bake. Check for doneness with a toothpick— it should come out clean when the brownies are ready.
- Step 7: Making the Frosting: While the brownies cool, prepare the frosting by melting butter, then gradually adding powdered sugar and vanilla, finishing with milk for a smooth consistency.
- Step 8: Finishing Touches: Spread the frosting evenly over the cooled brownies. This final layer adds a sweet, creamy finish that perfectly complements the moist brownies.
Storage Options
Banana Bread Brownies are best enjoyed fresh but can be stored to extend their delightful taste. At room temperature, they can be kept for up to three days when covered in an airtight container. For longer storage, refrigerate them for up to a week, ensuring they are tightly wrapped to prevent drying out. Alternatively, freeze them for up to three months; simply wrap the brownies individually in plastic wrap and then foil. Thaw at room temperature or gently warm in the microwave for a just-baked taste.
Variations and Substitutions
While the original Banana Bread Brownies recipe is a delight, you can easily modify it to suit different tastes or dietary needs:
- Gluten-Free Flour: Substitute the all-purpose flour with a gluten-free blend to cater to those with gluten sensitivities.
- Nut-Free: Omit the walnuts or replace them with seeds like sunflower or pumpkin for a similar crunch without the allergens.
- Vegan Adjustments: Use plant-based sour cream and butter, and replace eggs with an alternative like mashed avocado to maintain moisture.
- Different Nuts: Experiment with pecans or almonds instead of walnuts for a different flavor profile.
- Chocolate Chips: Add chocolate chips to the batter for a double chocolate version, enhancing the indulgent brownie experience.
Banana Bread Brownies
Ingredients
For the Brownies:
- 1 ½ cups granulated sugar
- 1 cup sour cream
- ½ cup 1 stick unsalted butter, at room temperature
- 2 large eggs at room temperature
- 3 ripe bananas mashed
- 2 teaspoons pure vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- ¾ teaspoon salt
- ½ cup walnuts finely chopped
For the Frosting:
- ½ cup unsalted butter
- 3 cups powdered sugar
- 1 ½ teaspoons pure vanilla extract
- 3 tablespoons milk
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking pan thoroughly with non-stick cooking spray to ensure the brownies release easily after baking.
- Prepare the Batter: In a large mixing bowl, combine the granulated sugar, sour cream, softened butter, and eggs. Utilize an electric mixer to blend the ingredients until they are thoroughly combined and the mixture is smooth. Following this, incorporate the mashed bananas and vanilla extract, mixing until the ingredients are fully integrated into the batter.
- Incorporate Dry Ingredients: Gradually add the all-purpose flour, baking soda, and salt to the wet mixture, mixing until the dry ingredients are fully combined and no streaks of flour remain. Fold in the chopped walnuts, ensuring they are evenly distributed throughout the batter.
- Bake the Brownies: Pour the prepared batter into the greased baking pan, spreading it evenly. Place the pan in the preheated oven and bake for approximately 20-30 minutes, or until a toothpick inserted into the center of the brownies comes out clean. Upon completion of baking, remove the pan from the oven and allow the brownies to cool slightly in the pan.
- Prepare the Frosting: While the brownies are cooling, begin preparing the frosting. In a medium-sized saucepan, melt the butter over medium heat. Continue cooking the butter until it reaches a medium brown color, which will impart a rich, nutty flavor to the frosting. Remove the saucepan from heat and gradually stir in the powdered sugar, adding it one cup at a time and mixing thoroughly after each addition. Finally, incorporate the milk and vanilla extract, stirring until the frosting is smooth and well-blended.
- Frost the Brownies: Once the brownies have cooled slightly, pour the frosting over the top, spreading it evenly across the surface. Allow the brownies to cool completely in the pan, ensuring the frosting sets properly. Once cooled, cut the brownies into squares and serve.
