What You’ll Need

Here’s a rundown of the ingredients you’ll need to whip up this amazing dessert. Don’t worry, it’s a pretty standard pantry list, with a few delightful additions:

  • 2 large Eggs: These bind the brownie batter and add richness.
  • 3 ripe Bananas, Mashed: The star of the show! The riper, the better, for maximum sweetness and moisture.
  • 1 1/2 cups Granulated Sugar: Provides the necessary sweetness and helps create that fudgy texture.
  • 1 cup Sour Cream: Adds incredible moisture and tanginess, enhancing the overall flavor profile.
  • 1/2 cup Unsalted Butter, Softened: Essential for creating a tender and moist brownie.
  • 2 teaspoons Vanilla Extract: Enhances the overall flavor and adds warmth.
  • 2 cups All-Purpose Flour: The structural base of our brownies.
  • 1 teaspoon Baking Soda: The leavening agent, crucial for a light and airy texture.
  • 3/4 teaspoon Salt: Balances the sweetness and enhances the other flavors.
  • 1/2 cup Walnuts, Chopped: Adds a delightful crunch and nutty flavor.
  • For the Frosting:
    • 1/2 cup Unsalted Butter, Softened: Creates a creamy and smooth frosting.
    • 3 cups Powdered Sugar: The base of the frosting, providing sweetness and texture.
    • 1 1/2 teaspoons Vanilla Extract: Adds depth and aroma to the frosting.
    • 3 tablespoons Milk: Helps achieve the perfect consistency.

Step-by-Step Instructions

Let’s get baking! Follow these easy steps to create your delicious banana bread brownies:

  1. Preheat & Prep: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. This prevents sticking and ensures easy removal of the brownies later. A little extra flour on the bottom never hurts!
  2. Mash Those Bananas: In a large bowl, mash the bananas until smooth. A few small lumps are okay, but avoid large chunks. Tip: Using a fork works perfectly for this!
  3. Combine Wet Ingredients: Add the softened butter, sugar, sour cream, and vanilla extract to the mashed bananas. Beat with an electric mixer until well combined and creamy. This step incorporates air, resulting in fluffier brownies.
  4. Add Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix; this can lead to tough brownies.
  5. Fold in Walnuts: Gently fold in the chopped walnuts. Don’t overmix; you want to retain some walnut texture.
  6. Bake: Pour the batter into the prepared pan and spread evenly. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs (not wet batter). Start checking around 30 minutes to avoid overbaking.
  7. Cool Completely: Let the brownies cool completely in the pan before frosting. This allows the brownies to set properly and prevents the frosting from melting. Patience is key here!
  8. Make the Frosting: While the brownies are cooling, prepare the frosting. In a medium bowl, beat the softened butter until light and fluffy. Gradually add the powdered sugar, beating until smooth. Stir in the vanilla extract and milk until you reach your desired consistency. If it’s too thick, add a touch more milk; if it’s too thin, add a little more powdered sugar.
  9. Frost & Serve: Once the brownies have cooled completely, frost them evenly with the prepared frosting. Slice and serve. Enjoy!

Tips for Success

To ensure your banana bread brownies turn out perfectly, here are a few helpful tips:

  • Use ripe bananas: The riper your bananas are, the sweeter and more flavorful your brownies will be. Overripe bananas are even better!
  • Don’t overmix the batter: Overmixing can lead to tough brownies. Mix until the ingredients are just combined.
  • Let the brownies cool completely before frosting: This will prevent the frosting from melting.
  • Adjust baking time as needed: Oven temperatures can vary, so keep an eye on your brownies and adjust the baking time accordingly.
  • Store properly: Store leftover brownies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.

Variations to Try

Feeling adventurous? Here are some fun variations to try:

  • Chocolate Chips: Add 1 cup of chocolate chips to the batter for extra chocolatey goodness.
  • Different Nuts: Substitute pecans, macadamia nuts, or hazelnuts for the walnuts.
  • Spiced Brownies: Add 1 teaspoon of cinnamon and 1/2 teaspoon of nutmeg to the batter for a warm, spiced flavor.
  • Gluten-Free Version: Substitute all-purpose flour with a gluten-free blend.
  • Vegan Version: Replace eggs with flax eggs (1 tablespoon flaxseed meal mixed with 3 tablespoons water per egg) and butter with vegan butter.

Storing and Reheating

To keep your banana bread brownies fresh and delicious, store them properly. At room temperature, in an airtight container, they will last for about 3 days. For longer storage, refrigerate them for up to a week. To freeze, wrap individual brownies tightly in plastic wrap, then place them in a freezer-safe bag. They can be frozen for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator and reheat for 15-20 seconds in the microwave for a warm, gooey treat. Alternatively, you can warm them gently in a low oven for a few minutes.

Frequently Asked Questions

Here are some common questions about this recipe:

  • Q: Can I substitute the sour cream? A: Yes, you can substitute the sour cream with plain yogurt or buttermilk for a similar tangy flavor and moisture. You might need to adjust the baking time slightly.
  • Q: How long do the brownies keep? A: Stored properly at room temperature, these brownies will last about 3 days. Refrigerated, they will stay fresh for up to a week, and frozen for up to 3 months.
  • Q: What if my bananas aren’t very ripe? A: While riper bananas are best for sweetness and moisture, you can still use less ripe bananas. Just add a tablespoon or two of extra sugar to compensate for the lack of sweetness.
  • Q: Can I make these brownies without walnuts? A: Absolutely! Omit the walnuts entirely, or substitute with another nut, chocolate chips, or even dried cranberries for a different flavor and texture profile.
  • Q: Can I use a different size pan? A: While a 9×13 inch pan is recommended, you can use a different sized pan; however, you will need to adjust the baking time accordingly. A smaller pan will require a shorter baking time, while a larger pan will require a longer baking time. Always check for doneness with a toothpick.
