Can I freeze banana bread brownies?

Yes! Wrap each brownie individually in plastic wrap and place them in an airtight container. They can last in the freezer for up to three months.

What can I substitute for sour cream?

Greek yogurt works well and provides a similar tangy flavor and texture.

Are these brownies gluten-free?

You can substitute the flour with a 1:1 gluten-free flour blend to make them gluten-free.

Can I omit the walnuts?

Absolutely. If you prefer a nut-free version, just leave them out.

Is the brown butter frosting necessary?

It’s optional, but it adds a rich, nutty flavor that complements the banana brownies perfectly.

Instructions

Preheat the Oven: Set your oven to 375°F (190°C). Grease a 13 x 9 inch baking pan thoroughly to ensure the brownies don’t stick.
Mix the Wet Ingredients: In a large bowl, beat together the sugar, sour cream, softened butter, and eggs until the mixture is smooth and creamy. This step is key for a soft and moist texture!
Add the Bananas and Vanilla: Fold in the mashed bananas and vanilla extract. These two ingredients add that unmistakable banana bread flavor we all know and love.
Incorporate the Dry Ingredients: Gradually mix in the flour, baking soda, and salt. Blend for about a minute to ensure all the ingredients are evenly combined.
Add the Walnuts: Stir in the chopped walnuts, which add a delightful crunch to each bite. If you’re not a fan of nuts, feel free to skip this step.
Bake: Spread the batter evenly in your prepared pan. Bake for approximately 25 minutes or until the top turns golden brown and a toothpick inserted into the center comes out clean.
Prepare the Frosting: While the brownies are cooling, heat the butter in a large saucepan over medium heat until it reaches a medium brown color. Carefully watch it to avoid burning.
Finish the Frosting: Remove from heat and gradually whisk in the powdered sugar, adding the milk little by little until the frosting reaches a smooth, spreadable consistency. Stir in the vanilla extract for an extra hint of sweetness.
Frost and Cool: Pour the frosting over the warm (but not hot) brownies and spread evenly. Allow the banana bread brownies to cool completely before cutting into squares.

Notes

Ripe Bananas: For the best banana flavor, use overripe bananas with brown spots. They’ll add natural sweetness and moisture.
Avoid Overmixing: When combining the wet and dry ingredients, mix just until everything is incorporated. Overmixing can make the brownies dense.
Browned Butter Frosting: This step adds a nutty, caramel-like flavor to the frosting. Make sure you don’t over-brown the butter, or it may taste burnt.
Nuts or No Nuts: If you have a nut allergy or prefer a smooth brownie, you can leave out the walnuts without affecting the texture too much.
