This banana bread bars with brown butter frosting recipe transforms overripe bananas into a moist and flavorful delight that embodies the cozy comforts of homemade treats. Whether you're creating a sweet surprise for loved ones or simply craving a nostalgic dessert, these banana bread bars are a delightful journey back to the heartwarming flavors of the past.
Grease and flour or parchment paper line a 12"x9" baking dish.
For the bars beat together sugar, sour cream, butter, and eggs in a large bowl until the mixture becomes creamy. Then, incorporate mashed bananas and vanilla extract.
Mix in the flour and baking soda to the banana mixture, making sure not to over mix.
Spread the batter into the prepared pan and bake in the oven for 20 to 25 minutes or until golden brown.
While the bars bake, prepare the frosting.
In a large saucepan over medium heat melt 1/2 cup butter until it starts boiling and turning a soft caramel color.
To the browned butter add powdered sugar, vanilla extract, and milk. Whisk the ingredients until smooth, and the consistency is thicker than a glaze but thinner than frosting.
Using a spatula spread the brown butter frosting over the warm bars.
Enjoy!
Notes
For the best flavor and sweetness, use super ripe bananas. The ones with brown spots on the peel are ideal as they mash easily and intensify the banana flavor in the bars.
Take your time when browning the butter for the frosting. The nutty aroma and golden brown color are signs of success. Be sure to avoid burning, as it will impact the flavor.
When combining the wet and dry ingredients for the banana bread bars, mix until just combined. Overmixing can lead to a denser texture, so a gentle hand is key.
To ensure the bars are perfectly baked, insert a toothpick into the center, and if it comes out clean or with a few moist crumbs (not wet batter), they are ready.
