Banana Bread Blondies Ingredients
• For a delightful treat, here are the key ingredients you’ll need for your Banana Bread Blondies:
For the Blondies
- Ripe Bananas – Provide natural sweetness and moisture; ensure they’re very ripe for the best flavor.
- Brown Sugar – Adds rich sweetness and a hint of caramel flavor; can be substituted with coconut sugar for a healthier alternative.
- All-Purpose Flour – Provides structure to the blondies; you can use gluten-free all-purpose flour for a gluten-free version.
- Eggs – Helps bind the mixture and makes the blondies moist; a flax egg can substitute for a vegan option.
- Butter – Enhances flavor and texture; coconut oil makes a great dairy-free alternative.
- Cinnamon – Adds warmth and spice to the flavor profile; nutmeg or cardamom can be used instead for a different taste.
For the Brown Butter Frosting
- Brown Butter – Creates a rich, nutty flavor in the frosting; ensure it cools slightly before mixing for smoothness.
- Powdered Sugar – Sweetens the frosting; feel free to adjust the amount based on your sweetness preference.
- Milk – Adds creaminess to the frosting; you can use any type of milk or a dairy-free alternative.
Step‑by‑Step Instructions for Banana Bread Blondies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease a 9×9-inch baking dish with butter or cooking spray to ensure your Banana Bread Blondies come out easily once baked. As you prepare, gather all ingredients to make this one-bowl wonder seamless and enjoyable.
Step 2: Mix the Base Ingredients
In a large mixing bowl, thoroughly mash 2–3 ripe bananas until smooth. Add in 1 cup of brown sugar and 1/2 cup of melted butter, mixing until well combined. The mixture should be creamy and slightly glossy, indicating that your base is ready to transform into the moist, fudgy texture of the blondies.
Step 3: Incorporate the Eggs
Crack in 2 large eggs into your banana mixture, stirring vigorously until fully incorporated. The blend will start to look cohesive and slightly fluffy. This step is crucial to ensure your Banana Bread Blondies have that perfect binding and moisture to create a rich end product.
Step 4: Combine the Dry Ingredients
Gradually sift in 1 cup of all-purpose flour and 1 teaspoon of ground cinnamon while gently folding the mixture. Be careful not to overmix; you want the batter to be just combined, which will help maintain the fudgy texture of the blondies. Stop mixing as soon as the flour disappears.
Step 5: Pour and Spread the Batter
Pour the prepared batter into your greased baking dish, using a spatula to spread it evenly across the surface. Ensure that the top is smooth, as this will create a lovely finish once the blondies are baked. Ready your oven to embrace this delicious treat!
Step 6: Bake to Perfection
Slide the baking dish into the preheated oven and bake for 25–30 minutes. Keep an eye on them; they’re ready when a toothpick inserted in the center comes out clean or with just a few moist crumbs attached. This is the moment when the delightful aroma of Banana Bread Blondies fills your kitchen.
Step 7: Cool and Frost
Once baked, remove the blondies from the oven and allow them to cool in the dish for about 10 minutes. This cooling period helps them set up perfectly. After cooling, gently lift them out of the dish and transfer them to a wire rack to cool completely before applying the frosting.
Step 8: Create the Brown Butter Frosting
While the blondies cool, make your brown butter frosting. In a saucepan over medium heat, melt 1/2 cup of butter, cooking until it is browned and fragrant. Allow it to cool slightly before whisking in 2 cups of powdered sugar and a splash of milk. The frosting should be smooth and spreadable for the perfect topping on your blondies.
Step 9: Frost and Serve
Once the blondies have cooled, generously spread the brown butter frosting over the top, creating a luscious finish. Cut them into squares, and you’ll have moist Banana Bread Blondies ready to impress your family and friends. Each bite will be a delightful experience!

Make Ahead Options
With these Fudgy Banana Bread Blondies, busy cooks can find joy in meal prep! You can make the batter up to 24 hours in advance by combining the wet ingredients (mashed bananas, brown sugar, and melted butter) and storing it in an airtight container in the refrigerator. It’s also a smart idea to prepare the dry ingredients (flour and cinnamon) ahead of time and keep them separate. When you’re ready to bake, simply mix in the chilled wet ingredients, add the eggs, and fold in the dry mix—this keeps the blondies just as moist and fudgy as if made fresh. After baking, allow them to cool completely before frosting, ensuring the brown butter frosting maintains its silky smooth texture. Enjoy saving time while treating your family to these delightful treats!
Tips for the Best Banana Bread Blondies
Perfectly Ripe Bananas: Use very ripe bananas for the utmost natural sweetness and moisture, elevating your Banana Bread Blondies to a new level.
Don’t Overmix: Mix the batter just until combined; overmixing can lead to dense and dry blondies. Embrace the one-bowl simplicity!
Cool Brown Butter Properly: Allow the brown butter to cool slightly before adding it to the frosting mix. This ensures a silky texture without lumps.
Test for Doneness: Insert a toothpick into the center; it should come out clean or with a few moist crumbs. This guarantees a fudgy, moist result.
Add Flavor Boosters: Consider mixing in chocolate chips or nuts for added flavor and texture, making your Banana Bread Blondies even more delightful.
Storage Tips for Banana Bread Blondies
Room Temperature: Keep your Banana Bread Blondies in an airtight container at room temperature for up to 3 days. This will help maintain their moist, fudgy texture while staying perfectly delicious.

Freezer: For longer storage, freeze your Banana Bread Blondies wrapped tightly in plastic wrap or aluminum foil, then place them in a freezer-safe bag. They’ll stay fresh for up to 3 months—ready for a sweet indulgence whenever you crave!
Reheating: To enjoy a warm treat, simply reheat the blondies in the microwave for about 10-15 seconds. This will refresh their fudginess and make that brown butter frosting even more irresistible!

Banana Bread Blondies Recipe FAQs
What kind of bananas should I use for this recipe?
Absolutely! It’s best to use very ripe bananas with plenty of brown spots for maximum sweetness and moisture. The ripeness means they’re bursting with natural sugars, enhancing the flavor of your blondies. If your bananas are not too ripe, they won’t provide that rich taste you’re looking for.
How should I store the Banana Bread Blondies?
For optimal freshness, keep your Banana Bread Blondies in an airtight container at room temperature for up to 3 days, or refrigerate them for up to a week. This helps retain their moist, fudgy texture. When you’re ready to indulge, allow them to come back to room temperature for that perfect, melt-in-your-mouth experience!
Can I freeze Banana Bread Blondies?
Absolutely! To freeze, wrap your blondies tightly in plastic wrap or aluminum foil, then place them in a freezer-safe bag. They can be stored in the freezer for up to 3 months. When you’re ready to enjoy, simply thaw them in the fridge overnight or leave them at room temperature for a few hours. A quick reheat in the microwave for 10-15 seconds will make them taste freshly baked!
What can I do if my batter seems too thick?
If your batter feels too thick, it might be due to overmeasuring the flour. To fix this, simply add one tablespoon of milk or water at a time until the desired consistency is reached. Avoid overmixing—it’s essential for a light, fudgy texture!
Are there any allergy considerations for this recipe?
Yes, this recipe includes common allergens such as eggs, gluten (if using all-purpose flour), and dairy (if using butter). For a gluten-free option, substitute with a gluten-free all-purpose flour blend. You can also replace eggs with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water) for a vegan version. Always check for any allergies before baking, especially if you’re sharing these delightful treats!
