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 help lift the finished blondies out easily. Spray the foil with cooking spray to prevent sticking.
Step 2: Prepare the Batter
In a medium mixing bowl:
1. Mix together the melted butter, light brown sugar, and salt until well blended.
2. Add in the egg, vanilla extract, and cinnamon; mix until fully combined.
3. Incorporate the mashed banana into the mixture.
Step 3: Combine Flour
Add the flour to your mixture:
1. Stir gently until combined and smooth.
2. Pour the batter into your prepared baking pan and smooth out the top.
Step 4: Bake
Place in the preheated oven:
1. Bake for about 25–30 minutes or until the center has set.
2. Remove from oven and allow to cool to room temperature in the pan.
Step 5: Make the Frosting
To prepare your frosting:
1. In a medium saucepan, melt the butter over medium heat.
2. Continue cooking until it reaches an amber color—stir constantly to avoid burning.
3. Add in brown sugar, milk, and a dash of salt; stir well and bring to a boil.
4. Remove from heat and let cool for about 10–15 minutes.
Step 6: Finish with Frosting
Once cooled:
1. Whisk in vanilla extract and powdered sugar until smooth.
2. Spread over cooled blondies evenly.
3. Allow frosting to set before slicing into squares and serving.

- Don’t Overmix: Combine ingredients until just mixed to avoid dense blondies. The goal is to keep them light and fluffy.
- Check for Doneness: Use a toothpick inserted into the center; it should come out clean or with just a few crumbs attached when done.
- Cool Completely Before Frosting: Allow the blondies to cool completely before adding frosting to prevent it from melting off.
Best Side Dishes for Banana Bread Blondies
Pairing side dishes with your Banana Bread Blondies can elevate your dessert experience. Here are some tasty options.

Common Mistakes to Avoid
When making Banana Bread Blondies, it’s easy to make some common mistakes. Here are a few to watch out for:
- Overmixing the batter: This can lead to tough blondies. Mix just until combined for a soft texture.
- Not measuring ingredients accurately: Using too much flour or sugar can affect the final product. Always use the correct measuring tools and techniques.
- Skipping the cooling time: Cutting into warm blondies can cause them to fall apart. Allow them to cool completely before slicing.
- Ignoring the baking time: Every oven is different. Keep an eye on your blondies towards the end of baking to avoid overcooking or undercooking.
- Using unripe bananas: Firm bananas won’t provide enough flavor or moisture. Use ripe bananas with plenty of brown spots for the best results.
