With Fresh Fruit
- Sliced Bananas: Top the blondies with fresh banana slices for an extra banana boost.
- Berries: Serve with strawberries or blueberries for a refreshing contrast and vibrant color.
With Ice Cream

- Coffee Pairing: Serve alongside coffee for a delightful afternoon treat.
How to Perfect Banana Bread Blondies
To make your Banana Bread Blondies even better, keep these tips in mind. Following these suggestions will ensure you achieve moist, delicious blondies every time.
- Use Ripe Bananas: Overripe bananas add natural sweetness and moisture to your blondies.
- Don’t Overmix the Batter: Mix just until combined to keep the texture fudgy and tender.
- Check for Doneness Early: Ovens vary; check your blondies 5 minutes before the suggested baking time to avoid overbaking.
- Cool Completely Before Frosting: Allow blondies to cool completely so that the frosting doesn’t melt off when spread.
- Experiment with Add-ins: Try adding nuts or chocolate chips for additional flavor and texture.

Best Side Dishes for Banana Bread Blondies
Pairing side dishes with your Banana Bread Blondies can create a more complete dessert experience. Here are some great options:
- Fruit Salad: A mix of seasonal fruits provides a refreshing contrast to the rich flavors of the blondies.
- Yogurt Parfait: Layer yogurt with granola and fresh fruit for a creamy, crunchy side that balances sweetness.
- Cheese Plate: Include cheeses like brie or goat cheese for a savory element that complements the dessert’s sweetness.
- Chocolate Fondue: Dip pieces of blondie into melted chocolate for an indulgent treat that’s fun to share.
- Nutty Granola Bars: These provide crunch and are a healthier option alongside your sweet treat.
- Espresso or Coffee: A strong cup of coffee enhances the flavors of both the blondies and any frosting used.
Common Mistakes to Avoid
Baking Banana Bread Blondies can be a delightful experience, but there are some common errors to watch out for.
- Using unripe bananas: Unripe bananas lack the sweetness and moisture needed for the best blondies. Always use ripe or overripe bananas for optimal flavor.
- Not measuring ingredients accurately: Baking is a science, and incorrect measurements can ruin your blondies. Use a kitchen scale or measuring cups to ensure precision.
- Overmixing the batter: Overmixing can lead to dense blondies instead of the desired fudgy texture. Mix just until combined for light and fluffy results.
- Skipping the cooling time: Cutting into warm blondies can cause them to crumble. Allow them to cool completely in the pan before slicing for clean edges.
- Ignoring oven calibration: Every oven is different; yours might not reach 350°F accurately. Use an oven thermometer to ensure your temperature is spot on for perfect baking.
Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 5 days.
- Place parchment paper between layers of blondies to prevent sticking.
Freezing Banana Bread Blondies
- Wrap individually in plastic wrap before placing them in a freezer-safe bag.
- They can be frozen for up to 3 months without losing flavor.
Reheating Banana Bread Blondies
- Oven: Preheat to 350°F, place blondies on a baking sheet, and heat for about 10 minutes.
- Microwave: Heat one blondie at a time on medium power for about 10-15 seconds until warm.
- Stovetop: Place blondie in a non-stick skillet over low heat, cover, and warm for about 5 minutes.
