Banana bars are super easy to make and so delicious. My 9 year old likes making these for the family. They come together super quick and the recipe can easily be doubled.

These bars hold together well enough to be finger food or served on a plate with a fork like cake. They are iced in vanilla frosting and sprinkled with walnuts. You can also add nuts to the batter before baking if you’d like. I’m not a big fan of cream cheese frosting, but you could totally ice them in that if you’d prefer.

Frosted Banana Bars Ingredients

(scroll down for printable recipe)

• 1/2 cup sugar
• 1/2 cup butter, softened
• 1 egg
• 2 mashed bananas
• 2 teaspoons vanilla
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt
• 1 cup flour

Vanilla Frosting

• 1/3 cup melted butter
• 3 cups powdered sugar
• 3 Tbsp. milk
• 2 teaspoons vanilla

Directions

1. Mix sugar, butter and egg together. add bananas and vanilla.
2. Add in dry ingredients and mix thoroughly.
3. Spread batter in a greased 9×13 baking dish and bake at 350 degrees for 22-25 minutes, or until toothpick inserted comes out dry.
4. Mix frosting ingredients together and spread over cooled banana bars. Sprinkle with 1/2 cup chopped walnuts (optional).

One pan makes 12 bars and they are just as delicious the second day. 

I make mine in a 9×13 baking dish, which is the perfect size for my family, but you can double the recipe for a crowd.

To Double Recipe

• Don’t double the frosting. Add 1 extra cup of powdered sugar, an extra tablespoon of milk, and increase butter to 1/2 a cup.
• Bake in a a 15″x10″ sheet pan for 25-27 minutes.

Banana bars are perfect to bring to a bbq or potluck. Another favorite sheet pan dessert is Texas sheet cake or our Rocky Road Texas Sheet Cake.
