How to Make Banana Bread Blondies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and line an 8 x 8 inch baking pan with aluminum foil. Leave an overhang on the sides to help lift out the finished blondies. Spray the foil with cooking spray and set aside.
Step 2: Prepare the Batter
In a medium bowl:
1. Mix together melted butter, light brown sugar, and salt until well combined.
2. Add in the egg, vanilla extract, and cinnamon; mix thoroughly.
3. Fold in the mashed banana until evenly distributed.
Step 3: Add Flour
Add flour to the mixture:
1. Stir until just combined and smooth; be careful not to overmix.
2. Pour the batter into your prepared baking pan and smooth out the top.
Step 4: Bake
Bake in your preheated oven for 25–30 minutes, or until the center is set. Once done, remove from oven and let cool to room temperature.
Step 5: Make the Frosting
For the frosting:
1. In a medium saucepan over medium heat, melt butter until it turns a nice amber color while stirring constantly—be cautious not to burn it.
2. Add light brown sugar, milk, and a dash of salt; stir continuously until it boils.
3. Remove from heat and allow cooling for about 10–15 minutes before whisking in vanilla extract and powdered sugar until smooth.

How to Serve Banana Bread Blondies
Banana Bread Blondies are delicious on their own, but they can be elevated with a few simple serving suggestions. Here are some ideas to enhance your dessert experience.
With Ice Cream

- Cinnamon Ice Cream – This will complement the cinnamon in the blondies and add an extra layer of flavor.

How to Perfect Banana Bread Blondies
Perfecting Banana Bread Blondies is about getting that moist, fudgy texture just right. Here are some tips to ensure your blondies turn out great every time.
- Use Overripe Bananas: The riper the bananas, the sweeter and more flavorful your blondies will be.
- Don’t Overmix: Mix just until combined after adding flour; overmixing can lead to tough blondies.
- Check for Doneness: Insert a toothpick into the center; it should come out with a few moist crumbs for perfect fudginess.
- Cool Completely: Allow blondies to cool fully in the pan before cutting; this helps them set properly.
- Experiment with Add-ins: Try adding nuts or chocolate chips for added texture and flavor variations.
