Banana Bread Bars with Browned Butter Frosting
Banana Bread Bars with Browned Butter Frosting are amazing. Okay, I have to admit I love frosting–on cookies, cakes, brownies–anything. But Browned Butter Frosting is in a league all of it’s own. And these Banana Bread Bars with Browned Butter Frosting are amazing. The Banana Bread Bars are filled with bananas and walnuts, and after browning the butter and making the frosting I sprinkled more walnuts on top for additional flavor and texture. They turned out heavenly. On top of that it’s a great way to use overripe bananas.

Last month John over bought bananas and I looked high and low trying to find recipes to use up about 18 overripe bananas. I made up a batch of Chunky Monkey Blondies, Banana Chocolate Chunk Snack Bars, Banana Cake with Butterscotch Fudge Frosting, Chocolate Banana Bread Streusel Muffins and Banana Blondies. All of them were wonderful, although I have to admit I am partial to any recipe with frosting. 🙂

Try Banana Bread Bars with Browned Butter Frosting for your next holiday potluck or gathering.
Here’s what I did.

I used these ingredients for the bars.

Mix butter, sugar, eggs, salt, baking soda, vanilla and sour cream (or Greek yogurt) with an electric mixer until smooth.

Add UNBLEACHED all-purpose flour. Bleached flour toughens baked goods. Add bananas and walnuts.

Stir ingredients with a wooden spoon to combine.

Spoon batter into a greased 9×13″ baking dish.

Bake at 350 for 45 minutes or until a toothpick inserted in center comes out clean. Cool completely.

I used these ingredients to make the frosting.

Place butter in a saucepan and bring to boiling and slightly browned. Remove from heat.

Add vanilla, half-and-half and powdered sugar and whisk to combine.

Spread frosting over cooled bars. Sprinkle with nuts. Cut into bars.

Banana Bread Bars with Browned Butter Frosting make great bars for tailgating parties.

These dessert bars are also great for any summer backyard barbecue.
Here’s the recipe.
