Banana blondies with brown butter frosting are chewy, soft, and easy to make. The blondies have a banana bread taste which pairs so well with the brown butter frosting.
What I love most about this recipe, besides that they taste amazing, is how they use up a ripe banana. I don't know about you but we always have some ripe bananas hanging around the house. This recipe use just one, compared to most banana muffins or bread recipes that use 3. This dessert comes together so easily and I'm sure will become your new go to for getting rid of those over ripe bananas.
I made this recipe with the help of my two young children. Lots of mashing, pouring, and mixing makes this recipe perfect to make with little helpers.

What is Brown Butter Frosting?
Just like the name sounds it is a simple frosting made up of brown butter. You get brown butter by slowly cooking the butter on the stove over medium heat until it reaches an amber colour. Cooking the butter gives it a sweet nutty flavour. If you've never tried it, it's easy to do and is really an amazing flavour. After the butter is browned you simply mix in the icing sugar, vanilla, and mix till smooth.
How to Make Banana Blondies
Preheat oven to 350F and line an 9x9 or 8x8 square baking dish with parchment paper
Banana Blondie Batter
In a large bowl whisk melted butter and brown sugar together. Add in the egg and vanilla extract and whisk till well combined. Add in the mashed banana and mix again.

In a separate medium sized bowl whisk flour, cinnamon, and salt together. Add the dry ingredients to the wet and use a rubber spatula to mix together. Mix just until no flour streaks remain.
Pour the batter into the lined pan and bake for 20 minutes or until the edges are just starting to turn a golden brown. Let the blondies cool completely in the pan before adding the frosting.

Brown Butter Frosting
In a small pot, over medium heat, add the butter. Cook the butter until it turns an amber brown colour, stirring occasionally. After the butter is browned remove from heat and let cool for 10 minutes.
Add the the icing sugar and vanilla extract and mix until smooth. Add the frosting on top of the cooled blondies and spread smooth. Let the frosting cool and competently set before slicing.

WHAT DOES SPOONED AND LEVELLED FLOUR MEAN?
Spooned and levelled flour refers to the way of measuring flour. To properly measure flour you should scoop spoonfuls of flour into your measuring cup and then scrape with a knife to level off the access. Scooping the measuring cup directly into your flour cause the flour to compress and getting more than the recipe calls for.
STORING THE BLONDIES
Store blondies at room temperature in an airtight container. They keep for 3 days after baking.
