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.

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.
