Ingredients
sugar
1 1/2 cups (granulated)
sour cream
1 cup (room temperature)
butter
1/2 cup (softened)
eggs
2 (large)
bananas
3-4 (mashed, ripe)
vanilla extract
2 teaspoons (pure)
all-purpose flour
2 cups (sifted)
baking soda
1 teaspoon
salt
3/4 teaspoon
walnuts
1/2 cup (chopped (optional))
butter
1/2 cup (for frosting)
powdered sugar
4 cups (sifted)
vanilla extract
1 1/2 teaspoons (for frosting)
milk
3 tablespoons (regular or non-dairy)
Instructions
1
Preheat your oven to 375°F (190°C). Grease and flour a 15x10-inch jelly roll pan.
2
In a large mixing bowl, combine the sugar, sour cream, softened butter, and eggs. Beat together until the mixture is creamy and well combined.
3
Incorporate the mashed bananas and vanilla extract, mixing until evenly blended.
4
Sift in the flour, baking soda, and salt, and mix on low speed for about 1 minute or until just combined. If using walnuts, fold them in gently.
5
Pour the batter into the prepared jelly roll pan and spread it evenly. Bake for 20 to 25 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean.
6
While the bars are baking, prepare the brown butter frosting. In a saucepan, melt the 1/2 cup of butter over medium heat. Continue to cook, swirling occasionally, until the butter turns a golden brown and has a nutty aroma. Be careful not to burn it.
7
Remove the pan from heat and quickly whisk in the sifted powdered sugar, vanilla extract, and milk. Mix until smooth; the frosting should be thicker than a glaze but thinner than traditional frosting.
8
Once the brownie bars are out of the oven, let them cool slightly, then spread the warm brown butter frosting over the top using a spatula for even coverage.
9
Allow the brownies to cool before cutting them into squares and serving. Enjoy!
