This recipe makes one large sheet pan of banana bars, so it's a great dessert for a potluck or party because it makes so many. The butter, sour cream, and mashed ripe banana all give these dessert bars a flavorful moist texture and the walnuts add a great crunch.
What do they taste like?
This is one of those recipes where you take your first bite and pause. You pause because you cannot believe how wonderfully incredible the morsel melting on your tongue tastes.
I dare those few crazy people who don't like bananas to try these banana bars and tell me they're not some of the most delicious treats they've ever enjoyed. I dare them.
These have that classic banana bread flavor that we all love, but the texture is more dense and it definitely feels more like a dessert than a breakfast treat. Especially with that frosting!
This is one of those recipes that is passed down from one generation to the next simply because it is a classic comfort food dessert.
The frosting is equally delicious.
These bars are definitely mouthwatering on their own, but when topped with brown butter vanilla bean frosting... heaven.
I know the cost of vanilla beans has skyrocketed in recent years, but I guarantee it is worth it in this frosting recipe. Go ahead. Splurge.
I decided to use brown butter in both the banana bars as well as the frosting because it adds a subtle nutty flavor. This goes perfectly with banana-walnut-anything.
Guess what... they freeze well too.
Worried about having too many frosted banana bars? Don't be.
Just bake the banana bars, allow them to fully cool, smother them in frosting, and slice into individual bars.
To freeze, I prefer to set them in the freezer uncovered for about 30 minutes to allow them to get really cold and hard. That way, when you wrap them, the frosting won't stick. My preferred method is to first wrap them in freezer paper and then place them in a plastic freezer bag with all of the air squeezed out.
That way I can grab a single banana bar whenever I want one and then just return the rest to the freezer when done.
Brown Butter Banana Bars
- 1/2 cup unsalted butter
- 1 1/2 cups sugar
- 1 cup sour cream
- 2 eggs (beaten)
- 1 1/2 cups bananas (mashed , about 3 large or 4 small)
- 1 tablespoon vanilla
- 2 cups all-purpose flour
- 1 teaspoon salt
- 1 teaspoon baking soda
- 1/2 cup chopped walnuts
- brown butter vanilla bean frosting (see recipe in notes)
- In a saucepan over medium heat, melt the butter. Whisk frequently, scraping the bottom. As the butter foams, continue whisking and scraping to release any brown bits that may stick to the bottom. Once the butter has sufficiently browned (not burned) and smells heavenly, remove from heat.
- Preheat oven to 375 degrees F. Line a 15 1/2 x 10 1/2 inch jelly roll pan with parchment paper or grease with butter.
- Add browned butter, sugar, sour cream, and eggs to the bowl of a stand mixer. Using the paddle attachment, mix on low speed for about a minute. Scrape sides, add bananas and vanilla, and continue to mix on low for another 30 seconds.
- In a separate bowl, combine flour, salt, and baking soda. Add dry ingredients to the wet. Start mixing on low speed just to combine and then flash on high speed for about 10 seconds to fully mix. Scrape sides, add nuts, and mix to combine.
- Spread batter in pan and bake in preheated oven until light brown, about 20 to 25 minutes.
- Allow bars to fully cool before you frost with brown butter vanilla bean frosting and cut into individual servings.
- These store really well in an airtight container in the freezer.
