What You’ll Need :
1-1/2 c. sugar
1 c. sour cream
1/2 c. butter, softened
2 eggs
1-3/4 (3 or 4) ripe bananas, mashed
2 tsp. vanilla extract
2 c. all purpose flour
1 tsp. baking soda
3/4 tsp. salt
1/2 c. chopped walnuts (optional)
Brown Butter Frosting:
1/2 c. butter
4 c. powdered sugar
1-1/2 tsp. vanilla extract
3 tbsp. milk
How to Make It :
1. Heat oven to 375F. Grease and flour
15×10-inch jelly roll pan. For the bars, in
a large bowl, beat together sugar, sour
cream, butter, and eggs until creamy.
Blend in bananas and vanilla extract. Add
flour, baking soda, salt, and blend for 1
minute. Stir in walnuts.
2. Spread batter evenly into pan. Bake 20
to 25 minutes or until golden brown.
3. Meanwhile, for frosting, heat butter in
a large saucepan over medium heat until
boiling. Let the butter turn a delicate
brown and remove from heat
4. Add powdered sugar, vanilla extract
and milk. Whisk together until smooth (it
should be thicker than a glaze but thinner
than frosting). Using a spatula, spread
the brown butter frosting over the warm
bars (the frosting will be easier to spread
while the bars are still warm)
