Ingredients
For the Blondies

- 1 cup light brown sugar
- 2 teaspoons vanilla
- 1 large egg
- 1 ½ -2 teaspoons cinnamon (to taste)
- ¼ teaspoon salt
- 1 cup flour

How to Make Banana Bread Blondies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line an 8 x 8 inch baking pan with aluminum foil, leaving an overhang on the sides. This will make it easier to lift out the blondies later. Spray the foil with cooking spray to prevent sticking.
Step 2: Prepare the Batter
In a medium bowl, mix together the melted butter, light brown sugar, and salt until well combined. Add in the egg, vanilla extract, and cinnamon. Stir until fully mixed. Then add in the mashed banana; mix again until incorporated.
Step 3: Combine Dry Ingredients
Next, gradually add in the flour. Stir until everything is well combined and smooth. Pour this batter into your prepared baking pan. Smooth out the top with a spatula.
Step 4: Bake
Bake in your preheated oven for 25–30 minutes or until the center has set. Once done, remove from oven and allow cooling to room temperature.
Step 5: Make the Frosting
For the frosting, melt butter in a medium saucepan over medium heat. Cook until it reaches a nice amber color while stirring constantly—be careful not to burn it! Add brown sugar, milk, and a dash of salt; stir well and bring this mixture to a boil. Remove from heat and let cool for about 10–15 minutes.
Step 6: Frost Your Blondies
Whisk in vanilla extract and powdered sugar until smooth. Spread this frosting over your cooled blondies once they have set. Allow frosting to firm up before slicing into squares for serving. Enjoy!

Common Mistakes to Avoid
When making Banana Bread Blondies, it’s easy to make a few common mistakes. Here are some tips to ensure your blondies turn out perfectly every time.
- Boldly measuring ingredients: Always measure your ingredients accurately. Too much flour can lead to dry blondies, while too little can cause them to be overly moist.
- Ignoring the ripeness of bananas: Use ripe bananas for the best flavor and sweetness. Overripe bananas provide the perfect texture and taste for your blondies.
- Skipping the cooling step: Allowing your blondies to cool completely before frosting is crucial. This ensures the frosting sets properly and does not melt off.
- Overbaking: Keep an eye on the baking time; every oven is different. Remove your blondies from the oven when a toothpick comes out with a few moist crumbs for that fudgy texture.
- Not lining the pan: Lining your pan with foil or parchment paper makes it easier to lift out the blondies after baking. Skipping this step could result in messy servings.
