Banana Bread Bars with Brown Butter Frosting Recipe

Cook Time: 30 minutes

Banana Bars with Frosting

Yields: 12 servings

Ingredients:

For the bars:
  • 1 cups white sugar
  • 1 cup sour cream
  • cup butter, softened
  • 2 large eggs
  • 1 cups mashed ripe bananas
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • teaspoon salt
  • cup chopped walnuts (optional)
For the frosting:
  • cup butter
  • 4 cups confectioners' sugar
  • 3 tablespoons milk
  • 1 teaspoons vanilla extract

Directions:

Step 1: Preheat your oven to 350F (175C). Grease and flour a 15x10-inch jelly roll pan.

Step 2: In a large bowl, use an electric mixer to beat together white sugar, sour cream, softened butter, and eggs until the mixture is smooth and creamy.

Step 3: Mix in the mashed bananas and vanilla extract until well combined.

Step 4: Gradually add the flour, baking soda, and salt, mixing for about 1 minute until everything is fully incorporated.

Step 5: If using walnuts, stir them in at this point until evenly distributed.

Step 6: Spread the batter evenly into the prepared pan and bake in the preheated oven for about 27 minutes, or until the bars are golden and a toothpick inserted into the center comes out clean.

Step 7: Remove from the oven and let the bars cool completely on a wire rack.

Step 8: While the bars are cooling, prepare the frosting. In a large saucepan, melt the butter over medium heat, stirring occasionally. Let the butter bubble and turn golden brown, which should take 3 to 5 minutes.

Step 9: Remove the saucepan from the heat and whisk in the confectioners' sugar, milk, and vanilla extract until smooth and creamy.

Step 10: Once the bars have cooled completely, spread the frosting evenly over the top.

Step 11: Cut the cooled banana cake into bars and serve.

Origin and History

The origins of banana bread are not entirely clear, but it is believed to have emerged during the early 20th century, becoming a popular dish in American homes during the Great Depression. The widespread availability of baking soda and the increasing consumption of ripe bananas made banana bread a pantry staple. Over time, variations emerged, with bakers adding nuts, chocolate chips, or frostings to enhance the flavor. The banana bread bars with brown butter frosting recipe offers a modern twist on the classic banana bread by turning it into a decadent dessert with the rich, nutty flavor of brown butter frosting, adding a luxurious layer of sweetness.

Regional Variations

Banana bread bars with brown butter frosting are a popular treat across many regions in the United States, particularly in the Midwest and South, where banana bread is a long-time favorite. While banana bread itself is a beloved dish in many households, the bar version with frosting has become a trendy option for parties, bake sales, and gatherings. In some regions, its common to add chopped walnuts or pecans to the batter, which adds texture and complements the sweetness of the ripe bananas. Some variations even incorporate spices like cinnamon or nutmeg, which are popular in Southern banana bread recipes. Additionally, while frosting is often optional, the use of brown butter frosting has become increasingly popular in contemporary adaptations, offering a deeper, more complex flavor.

How It Differs From Similar Dishes

Banana bread bars with brown butter frosting differ from traditional banana bread in a few key ways. First, these bars are baked in a jelly roll pan, giving them a denser, more cake-like texture compared to the loaf form of banana bread. The frosting, made with brown butter, sets these bars apart from classic banana bread, which is often served without any frosting. The brown butter adds a rich, toasty flavor that enhances the sweetness of the banana base and creates a unique combination of flavors that are not found in traditional banana bread. The addition of frosting also transforms these bars from a simple snack into a more indulgent dessert.

Where It Is Typically Served

Banana bread bars with brown butter frosting are a versatile dessert and can be served in a variety of settings. They are a popular choice for casual gatherings, family dinners, or as a sweet treat for breakfast or brunch. The bars are also a favorite at bake sales, potlucks, and picnics due to their easy portability and large yield. They can be served at holiday gatherings, especially during the fall and winter months when bananas are at their ripest and baking is a favorite pastime. The moistness of the bars paired with the rich frosting makes them a comforting dessert that appeals to all ages.

FAQ about Banana Bread Bars with Brown Butter Frosting Recipe

Store the banana bread bars in an airtight container at room temperature for up to 3 days. If you want to keep them longer, refrigerate them for up to a week. You can also freeze the bars for up to 3 months. Be sure to wrap them tightly in plastic wrap or aluminum foil before freezing.

Yes, you can make these banana bread bars without walnuts. You can skip the walnuts entirely or substitute them with another nut, such as pecans, or leave them out for a nut-free version.

Yes, you can substitute sour cream with Greek yogurt or buttermilk. Some users have successfully used plain yogurt or even cream cheese in place of sour cream for slightly different textures and flavors.

The frosting in this recipe contains a significant amount of powdered sugar, which can make it overly sweet for some people. If you find it too sweet, consider halving the amount of powdered sugar in the frosting or drizzling the frosting over the bars instead of spreading it thickly.

You can reduce the sugar in the banana bread bars slightly, but keep in mind that this may affect the texture and moisture of the bars. Some users have successfully reduced sugar by up to 1/4 cup without negative effects, especially when using ripe bananas which add natural sweetness.

If your banana bread bars are undercooked in the center, bake them for an additional 5-10 minutes. If necessary, cover the bars loosely with foil to prevent the edges from overbaking while the center continues to cook.

To make the frosting less sweet, you can reduce the amount of powdered sugar or add a small amount of cream cheese to balance the sweetness. Some people also prefer to use less butter and milk for a lighter, less sugary frosting.

Yes, you can make the banana bread bars gluten-free by using a gluten-free all-purpose flour blend. Many users have successfully made the recipe gluten-free without any major issues, though the texture might vary slightly.

Yes, you can freeze the frosting separately. Let it cool completely, then store it in an airtight container. When you're ready to use it, let it thaw in the fridge overnight, then reheat gently to soften it before spreading.

To prevent your banana bread bars from becoming too dry, be sure not to overbake them. Check for doneness by inserting a toothpick into the center of the bars; it should come out clean but not dry. Also, using very ripe bananas helps add moisture to the bars.

I baked these today and I'm grateful for the tips about reducing the powdered sugar in the frosting from other reviewers. I was worried that 4 cups would be too sweet, and it definitely would have been. I followed the advice and halved the powdered sugar while adding 2 tsp of vanilla instead of 1 1/2 tsp. I substituted pecans for walnuts since that's what I had on hand. Baking required an extra 5 minutes, but the end result was delicious! I also lined the pan with parchment paper, which was a good decision. I will definitely be making this again.

My boyfriend and I absolutely adore banana bread, so when we stumbled upon this recipe, we decided to give it a shot. And boy, were we pleasantly surprised! The result was simply fabulous. I made a couple of tweaks to the recipe - I used 2 cups of bananas (since that's what I got when I mashed the ripe bananas), baked it in a 13x9 glass pan, and cooked it for 42 minutes instead of the original 27 minutes. This recipe is incredibly easy to follow, making it accessible to anyone. Moreover, the banana bread tastes just as delectable without the frosting as it does with it. Highly recommended!

I halved the amount of powdered sugar and incorporated 1/4 cup of cream cheese into the frosting. This adjustment resulted in a more delicate and balanced flavor, rather than being too overwhelming. For the cake, I reduced the sugar by 1/4 cup and included two tablespoons of Greek yogurt. The outcome was a moist and fluffy cake that wasn't overly sweet.

Great recipe! I substituted softened cream cheese mixed with a tablespoon of milk for sour cream since I didn't have any. I also used 1/2 cup of brown sugar and 1 cup of organic sugar. The frosting was delicious but a bit too sweet for my taste. I'm curious if there's a way to reduce the sweetness. I poked holes in the cake while it was still hot before adding the frosting, to allow the flavor to seep in like a tres leches cake. For a stronger banana flavor, make sure to use very ripe, almost blackened bananas—I used three large ones.

This recipe was fantastic! However, I found the frosting to be a bit too sweet for my taste. Nevertheless, my entire family absolutely adored it! They even went as far as to proclaim that this was the best thing I've cooked in a long time. If I were to prepare it again, I would consider reducing the amount of frosting by half and drizzling it over the bars instead of spreading it like cake frosting. Overall, a great recipe!

An amazing recipe! My 78-year-old brother-in-law claims it's the closest he's ever tasted to his mother's recipe, which she made for his birthday every year. I made two adjustments: I substituted plain yogurt for the sour cream, and I found the icing to be too sweet, so I reduced the sugar by half and spread a thin layer on top of the finished bars. This is definitely our favorite banana recipe to date.

Absolutely scrumptious! I decided to use my 11 x 13 cake pan instead of the jelly roll pan to achieve a more cake-like texture, and baked it for 40 minutes. Without a doubt, I will be making this again.

I brought this dish to work once, and it received glowing reviews from everyone. I had to search for the recipe online because the copy I had saved didn't list the ingredients for the frosting. Currently, I have bananas ripening to make it again.

I used three bananas and then added applesauce to make it 1 and 3/4 cups. These muffins turned out incredibly moist and delicious!
