Who loves bananas?

We are definitely obsessed in my family!! We buy 2 bunches a week! YUP. It’s a great snack that the kids love and one that I don’t mind them eating at all. Occasionally, we are left with a few by the end of the week so I’m often baking with those leftover bananas.

The kids love these baked goods just as much! I’m right there with them and love a warm slice of banana bread or a delicious banana muffin in the morning. One recipe I had yet to try was Banana Bars. My mom wanted to try them, and I’m glad she did because they were a hit!

Not sure if it’s the sour cream or loads of butter that make these bars so moist and delicious OR the cream cheese frosting, but either way, they were amazing. They obviously didn’t last long at my family’s house, and have been added to the “recipes to make with over-ripe bananas” list. 😉

The Browner, the better

When it comes to baking, the browner and blacker a banana is, the better it will be! A green or yellow banana will never yield a good banana flavor for baking. 

Here are the instructions for using ripened bananas to make these bars:

Bars. In a large mixing bowl, beat your butter with an electric mixer for about 30 seconds. Add sugar, baking soda and salt, then beat until combined. Beat in bananas, eggs, sour cream, and vanilla. Stir in flour. Spread in a greased 15x10x1 baking pan, and bake at 350 for 25-30 minutes. Let cool.

Frosting. Beat cream cheese and butter until smooth. Beat in powdered sugar and vanilla until combined. Spread over the cooled banana cake base and cut into bars. Decorate as desired!

Tips and storing

Decorating your banana bars: We like to decorate our bars with banana slices. But be careful you don’t put them on too early because the bananas will get brown. Some other ways you could decorate are:

  • Chopped walnuts
  • Caramel syrup
  • Chocolate chips
  • Chocolate shavings
  • Sprinkles
  • Berries

Storing. You can store unfrosted banana bars at room temperature, but if you put the cream cheese frosting on, they will need to be stored in the refrigerator. Keep them covered, and they can last for up to 5 days.

If you decorate with fruit, I recommend taking it off before storing, and using fresh fruit before serving again.

As I mentioned before the bars are so moist and delicious (even without the frosting!!) I promise you’ll love these bars because they are irresistible!
