Banana Bread Bars with Brown Butter Frosting

I always buy bananas with the best intentions of having one each morning for a healthy, well-rounded breakfast. And then I eat a giant bowl of Lucky Charms. :/ Luckily, over-ripe bananas are perfect for banana bread!

I found this recipe on Pinterest. I do love a good ol’ banana bread, but I was excited to try a different take on a favorite. I’ll admit, the frosting was really the selling point!

Banana Bread Bars:

  • 1-1/2 c. light brown sugar
  • 1 c. sour cream
  • 1/2 c. butter, softened
  • 2 eggs
  • 4 ripe bananas, mashed
  • 2 tsp. vanilla extract
  • 2 c. all purpose flour
  • 1 tsp. baking soda
  • 3/4 tsp. salt
  • 1 teaspoon ground cinnamon
  • 1/2 c. chopped walnuts

The original recipe called for regular sugar and didn’t include cinnamon.

Brown Butter Frosting:

  • 1/2 c. butter
  • 4 c. powdered sugar
  • 1-1/2 tsp. vanilla extract
  • 3 tbsp. milk


1) Preheat the oven to 375°F. Grease and flour a 9×13 pan.

2) In a large bowl, mix the sugar, sour cream, butter, and eggs. Stir in the mashed bananas and vanilla extract. Add flour, baking soda, salt, and cinnamon. Then, add in walnuts.

3) Spread batter evenly into pan. Bake 20 to 25 minutes or until golden brown, and the middle is firm when you shake the pan.

4) While the Banana Bread Bars are baking, heat butter in a large saucepan over medium heat until boiling. Let the butter turn a light brown and remove from heat immediately. Add powdered sugar, vanilla extract and milk. Whisk together until smooth.

I had to use 4 tablespoons of milk to get it to a spreadable consistency.

5) When the Banana Bread Bars are done, remove from the oven and immediately spread the Brown Butter Frosting over them.

This is a treat which requires a glass of milk to consume — rich, and sweet, and delicious!

Banana Bread in a Mug

Day 3 of my 7-Day Microwave Mug Challenge! Today, we are having Bannana Bread! Check out the original recipe here. It’s a great recipe, but I made a few alterations: some on purpose, others … not.


  • 3 tablespoons flour
  • 1 tablespoon + 1 teaspoon sugar
  • 2 tablespoons brown sugar
  • 1/8 teaspoon salt
  • 1/8 teaspoon baking powder
  • 1/8 teaspoon baking soda
  • 1 egg
  • 1/4 teaspoon vanilla extract
  • 1 tablespoon vegetable oil
  • 1 tablespoon milk
  • 1 ripe banana, mashed
  • pecan pieces, handful
  • brown sugar, to sprinkle on top

First, I have to ask: does anyone actually own a 1/8 teaspoon measurer? Or am I the only one just eyeballing it with a 1/4 teaspoon measurer?

1) Use a big mug because the banana bread will rise and expand and attempt to do summersaults in your mircowave. I selected this lovely Harry Potter mug. 🙂

I solemnly swear I am up to no good!

2) In a bowl, whisk flour, sugar, brown sugar, salt, baking powder, and baking soda. Now, I accidentally forgot to add the brown sugar in the batter when I made it because the original directions just said to add sugar. I missed the implied plural. And so, I have made my directions a smidgen more O.C.D. 🙂

3) Add egg and combine until incorporated with dry ingredients. Don’t over mix!

4) Stir in vanilla, vegetable oil, milk, mashed banana, and pecans. I added the pecans to this recipe, because I like a little crunch! Feel free to use any nut you like, or make yours sans nuts.

5) Pour the mixture into your mug. Pop into the microwave for 1 minute and 30 seconds.

6) Remove and sprinkle with brown sugar and more pecans. Microwave an additional 1 minute. Let sit for 1-2 minutes because it will be nuclear hot!

You might find someone to help you eat this, because I found the portion to be a little much for one person, at least for breakfast anyway.

It turned out more like a yummy banana cake — perhaps because I missed the brown sugar in the batter — but I do believe I made up for my error by garnishing with brown sugar and pecans. They make a delicious, caramelized topping!

What I love the most about these microwave recipes, besides the convenience of single servings and fast cook time, is that I have yet to go shopping for supplies. They all use basic ingredients that most people have in their home on an average day.
