Step‑by‑Step Instructions for Banana Bread Blondies
Step 1: Melt the Butter
Begin by melting 1 cup of unsalted butter in a microwave-safe bowl or a saucepan over low heat. This should take about 1-2 minutes in the microwave or 5-7 minutes on the stove. Once melted, allow the butter to cool slightly while you gather the other ingredients, ensuring a warm but not hot mixture.
Step 2: Mix Butter and Sugar
In a large mixing bowl, combine the melted butter with 1 ½ cups of packed light brown sugar. Using a whisk, mix these ingredients together until smooth and well-blended, which should take about 1-2 minutes. The mixture will be shiny and somewhat thick, creating a luscious base for your Banana Bread Blondies.
Step 3: Add Eggs and Vanilla
Next, beat in 2 large eggs, one at a time, whisking well between each addition. Follow this by stirring in 1 teaspoon of vanilla extract until fully incorporated. Your mixture will start to lighten in color and become fluffy, indicating the eggs are combining well with the sugar and butter base.
Step 4: Incorporate Mashed Bananas
Add 1 cup of mashed ripe bananas to the bowl, which is about 2-3 medium bananas. Stir gently until just combined, ensuring the bananas are evenly distributed throughout the batter. This step adds delicious moisture and sweetness to your Banana Bread Blondies.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt. This step is crucial for even distribution of the leavening agents, which will help ensure that your blondies rise perfectly as they bake.
Step 6: Mix Wet and Dry Ingredients
Gradually add the dry ingredients to the banana mixture, folding them together with a spatula. Mix until just combined, being careful not to overmix. The batter should be thick and slightly lumpy, which is ideal for the rich texture of your Banana Bread Blondies.
Step 7: Fold in Add-Ins
If desired, fold in ½ cup of chopped walnuts or pecans, along with ½ cup of chocolate chips and ½ cup of toffee bits. These add-ins will enhance both flavor and texture, giving your blondies a delightful crunch and richness when baked.
Step 8: Preheat the Oven and Prepare the Pan
Preheat your oven to 350°F (175°C). While it warms up, grease and flour a 9x13 inch baking pan or line it with parchment paper for easy removal after baking. Ensure the pan is well-prepared to prevent the blondies from sticking.
Step 9: Pour and Spread the Batter
Pour your thick batter into the prepared baking pan. Using a spatula, spread the batter evenly across the pan, smoothing the top to ensure it bakes uniformly. This will help in achieving that beautiful golden brown top, characteristic of delicious Banana Bread Blondies.
Step 10: Bake to Perfection
Bake the blondies in the preheated oven for 25-30 minutes. They are done when a toothpick inserted into the center comes out with a few moist crumbs attached. Keep an eye on the edges; they should look slightly golden but not burnt for the best texture.
Step 11: Cool the Blondies
Once baked, remove the pan from the oven and allow the blondies to cool completely in the pan on a wire rack. This cooling process is essential to achieve the perfect chewy texture throughout the bars before you add the glaze.
Step 12: Prepare the Brown Butter Glaze
For the brown butter glaze, melt 4 tablespoons of unsalted butter in a light-colored saucepan over medium heat. As it cooks, swirl occasionally for about 5-7 minutes until it turns a nutty brown color and releases a rich aroma. Remove it from the heat and let it cool slightly.
Step 13: Make the Glaze
In a medium bowl, whisk together 2 cups of powdered sugar, the cooled browned butter, 3-4 tablespoons of milk or heavy cream, ½ teaspoon of vanilla extract, and a pinch of salt. Start with 3 tablespoons of milk, adjusting to reach a smooth, pourable consistency that will beautifully glaze your Banana Bread Blondies.
Step 14: Finish and Serve
Once the blondies are completely cool, pour the brown butter glaze over the top, spreading it evenly with a spatula. If you’d like, top with sprinkles for a fun and colorful finish. Cut the blondies into squares and they are ready to serve, showcasing their decadent banana flavor and delightful glaze.
Step 15: Store Properly
Store any leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week to keep your Banana Bread Blondies fresh and delicious!

Banana Bread Blondies Recipe FAQs
How ripe should the bananas be for this recipe?

What should I do if my blondies turn out too dry?
If you find that your Banana Bread Blondies are too dry, it might be due to overmixing the batter or baking for too long. To ensure they stay moist, mix until just combined and keep an eye on the baking time; check for doneness at the 25-minute mark. If they are slightly underbaked, they'll continue to set as they cool, resulting in a perfect gooey texture.
Are these blondies suitable for those with nut allergies?
Very! If you or someone you're serving has nut allergies, simply omit the nuts from the recipe. The blondies will still be delicious and moist thanks to the bananas and other ingredients. You can also add extra chocolate chips or toffee bits for added texture without using nuts!
How long should I wait before glazing the blondies after baking?
It's important to let your Banana Bread Blondies cool completely in the pan on a wire rack before adding the brown butter glaze. This usually takes about 30-45 minutes. Cooling prevents the glaze from melting and running off, allowing it to set beautifully on top for that perfect finish.
