There’s something about the smell of banana bread baking in the oven that always makes me feel like the apartment is being wrapped in a warm happy hug. And what’s better than a slice of light, moist banana bread? How about topping it off with a sweet brown butter frosting?
I found this super delicious recipe on The Girl Who Ate Everything blog, and since the first time I brought these sour cream banana squares into my office, they’ve been requested over and over again. So if you’re looking for a classic breakfast treat with a bit of a sweeter twist, try them. I promise they will be a huge hit (if they even make it out of the front door!)
SOUR CREAM BANANA SQUARES
Ingredients for banana squares:
1 ½ cups sugar
1 cup sour cream
½ cup butter, softened
1 ¾ cups (about 3 or 4) ripe bananas, mashed
2 teaspoons vanilla
2 cups flour
1 teaspoon baking soda
¾ teaspoon salt
½ cup chopped walnuts
Ingredients for brown butter frosting:
½ cup butter
4 cups powdered sugar
1 ½ teaspoons vanilla
About 3 tablespoons whole milk
- Heat oven to 375ºF. Grease and flour a 9×13 pan.
- Add the sugar, sour cream, butter, and eggs to a stand mixer and beat until creamy. Blend in the bananas and vanilla and mix for about one minute.
- In a separate bowl, whisk together the flour, baking soda, and salt. Slowly add the dry ingredients into the wet ingredients, and blend for about one minute, until combined.
- Stir in the walnuts with a rubber spatula.
- Spread the batter into the pan. Bake for 20 to 25 minutes until golden brown. Cool slightly until warm, but not hot, and then frost with the brown butter frosting immediately.
- For the browned butter frosting, heat the butter in saucepan over medium heat past the melting point until it is boiling and a delicate brown (but not burnt). Remove the butter from the heat and immediately add the powdered sugar, vanilla, and milk to the saucepan. The mixture should be thicker than a glaze and thinner than a frosting.
- Using a rubber spatula, smooth over the top of the banana squares immediately.
Please note: Don’t worry if the frosting seems too thick to spread on the banana squares at first. The frosting will be much easier to spread once it is poured on top of the warm squares.
