How to Make Banana Bread Brownie Bars
-
Preheat your oven to 375°F (190°C) and grease a 15×10-inch jelly roll pan. This step ensures that your bars will bake evenly and not stick!
-
Combine the sugar, sour cream, butter, and eggs in a large bowl. Use an electric mixer to beat these ingredients together until creamy and smooth; this should take about 2-3 minutes.
-
Mix in the mashed bananas and vanilla extract. Gently stir until everything is well incorporated, and the mixture is velvety and fragrant.
-
Add the flour, baking soda, and salt into the bowl. Mix until just combined, being careful not to overmix. If you’re using walnuts, fold them in gently at the end.
-
Pour the batter into the prepared pan, smoothing it out evenly. Bake in the preheated oven for 20-25 minutes, or until the edges are golden and the center is just set.
-
Brown the butter in a medium saucepan over medium heat for the frosting. Keep stirring until it turns a rich golden brown with a nutty aroma, then remove from heat.

Expert Tips for Banana Bread Brownie Bars
-
Use Ripe Bananas: Choose overripe bananas for maximum sweetness and moisture, enhancing the flavor of your Banana Bread Brownie Bars.

Banana Bread Brownie Bars Recipe FAQs
What type of bananas should I use for the best flavor?
Absolutely, overripe bananas are your best bet for these Banana Bread Brownie Bars! Look for fruits that are soft with brown spots on the skin, which indicates they are extra sweet and will contribute to the moistness of your brownies. If they are squishy and have a lot of dark spots, that’s when they’re at peak flavor.
How should I store leftover Banana Bread Brownie Bars?
You can store these bars in an airtight container at room temperature for 2-3 days. This keeps them soft and delicious, just as they are meant to be. If you want to keep them a little longer, pop them in the fridge for up to 5 days. Just remember to let them come to room temperature before diving in for the best texture.
Can I freeze Banana Bread Brownie Bars?
Absolutely! To freeze these delightful bars, wrap them tightly in plastic wrap and then in foil to protect them from freezer burn. They can stay fresh in the freezer for up to 3 months. When you’re ready to enjoy them, just thaw in the fridge overnight or let them sit at room temperature for a couple of hours before serving.
What should I do if my brownie bars are too dry?
If your Banana Bread Brownie Bars come out drier than desired, here’s a tip: ensure you’re measuring your flour correctly—overpacking can lead to dryness. Also, check your baking time; they should be baked until just set. If they’re already baked, try serving them with a scoop of ice cream or drizzle a bit of warm chocolate sauce over the top for added moisture!
Are there any dietary considerations for this recipe?
Yes, if you have dietary restrictions, you can modify this recipe! Use flax eggs instead of regular eggs for a vegan option, substitute margarine for butter for dairy-free, and choose gluten-free flour if needed. Always be sure to check your mix-ins, like walnuts or chocolate chips, for any allergens.
How long does the brown butter frosting stay good?
The brown butter frosting can last about 3 to 5 days when stored in an airtight container in the fridge. If it starts to harden, just give it a quick whip or reheat gently to achieve that smooth, spreadable texture again! It’s too good to waste, so enjoy it while you can!
