Who doesn’t love banana bread? These brownies are hearty, they taste great, and best of all, they come with an amazing, buttered frosting on top that’s just mouth0-watering and delectable. They’re the perfect little sweet treat for those nights you’re feeling like you want a little something but aren’t totally sure what.


Do I have to wait for the bars to stay warm or can I frost them as they come out of the oven?

It’s best if this is done when it’s warm.

It’s hard to frost if they’re cold, so don’t do it when it’s cold.

Don’t do these fresh out of the oven either, since it’ll melt, and it’ll ruin the consistency of the butter over the top of this.

Are these safe to put in the fridge?

Yes, these are safe to put in the fridge. If you do decide to hold onto this, they’re good for a few days. Just make sure that, if you do this, take them out of the fridge and warm them up before you serve them. that way the butter melts a little bit and creates a great topping to the bars.

Banana Bread Brownies

Banana Bread Brownies


  • 1-1/2 c sugar
  • 1 c sour cream
  • 1/2 c butter
  • 2 eggs 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
  • BROWN BUTTER FROSTING 1/2 c butter 4 c powdered sugar 1 1/2 tsp vanilla extract 3 Tbsp milk


Make sure to heat up the oven to 375 degrees.

Grease and add flour to a jelly roll pan that’s 15 inches by 10 inches.

For the bar portion of this, get a large bowl, take the eggs, sugar, butter, and sour cream and then beat this until it becomes creamy.

Add the bananas along with the vanilla extract to this and then blend it in.

Add in the salt, baking soda, and then add some more flour to this and then blend it for an extra minute, then take the walnuts, add them in, and then stir it until it’s fully incorporated with the bars.

Take the batter and then spread this into a pan in an even manner until it’s all out on the pan itself

Bake this in the pan for about 25 minutes, or until the bars have a golden brown color to this.

While it’s baking, you want to make the frosting. Get a saucepan and heat up the butter and then keep that on heat that’s medium until this starts to boil. You want the butter to become a brownish color, and then take it off the heat right away.

Put the vanilla extract, the powdered sugar, and the milk together into this, and then whisk this until the whole mixture is fully smoothed. You want this to be more thick than a glaze, but not a total frosting.

Once the bars are done, take this and put it over the bars, making sure that they’re not cold but instead nicely warm. It’s easier for the frosting to spread out when the bar is still in a warm state.

Once they’ve cooled down and the butter is a little bit hard, cut it up into squares and then serve!
