How to Make Banana Bars with Brown Butter Icing
Step 1: Preheat the Oven
Begin by heating your oven to 375°F (190°C). Prepare an 8×8 baking dish by lining it with parchment paper.
Step 2: Mix Wet Ingredients
In a large bowl:
1. Beat together the sugar, sour cream, softened butter, and egg until creamy.
2. Blend in the mashed bananas and vanilla extract until well combined.
Step 3: Add Dry Ingredients
Add the following dry ingredients to the wet mixture:
– All-purpose flour
– Baking soda
– Salt
Stir together until just combined. Be careful not to over-mix.
Step 4: Bake the Bars
Spread the batter evenly into your prepared pan. Bake for about 20 to 25 minutes or until golden brown. Let them cool slightly before removing from the pan using the parchment paper.
Step 5: Prepare Brown Butter Icing
In a medium saucepan:
1. Melt ½ cup butter over medium-high heat.

How to Serve Banana Bars with Brown Butter Icing
Serving Banana Bars with Brown Butter Icing can elevate your dessert experience. Here are some creative ways to delight your guests or enjoy them yourself.
Classic Presentation
- Serve the bars on a decorative platter for a simple yet elegant look. Cut them into squares and dust with additional powdered sugar for a touch of sweetness.
À la Mode
- Top each bar with a scoop of vanilla ice cream. The warm banana bars paired with cold ice cream create a delicious contrast that is hard to resist.
With Fresh Fruit
- Add slices of fresh fruits such as strawberries, blueberries, or raspberries on the side. The acidity from the fruits balances the sweetness of the bars nicely.
Drizzled Sauce
- Drizzle caramel or chocolate sauce over the bars before serving. This adds an extra layer of flavor and makes for a visually appealing dessert.
Coffee Pairing

How to Perfect Banana Bars with Brown Butter Icing
Perfecting your Banana Bars with Brown Butter Icing ensures they turn out moist and flavorful every time.
- Use very ripe bananas: The riper the bananas, the sweeter and more flavorful your bars will be.
- Don’t overmix: Mix the batter until just combined to keep your bars light and fluffy.
- Monitor baking time: Check for doneness at 20 minutes; they should be golden brown and a toothpick inserted should come out clean.
- Cool before icing: Allow the bars to cool slightly before adding icing, which helps it melt into a delightful glaze.
- Adjust icing thickness: If your icing is too thick, add a splash more milk for easier spreading.
Best Side Dishes for Banana Bars with Brown Butter Icing
Pairing side dishes with Banana Bars can enhance your dessert spread. Here are some tasty suggestions:
- Fruit Salad: A mix of seasonal fruits like melons, berries, and citrus adds brightness to your meal.
- Yogurt Parfait: Layer yogurt with granola and fresh fruit for a refreshing and creamy contrast.
- Nutty Granola: Serve crunchy granola on top or as a side for added texture and flavor.
- Cheese Platter: Include soft cheeses like brie or goat cheese that pair well with sweet desserts.
- Mini Muffins: Offer banana or blueberry muffins as another sweet treat that complements the bars.
- Chia Pudding: A light chia pudding made with coconut milk can provide a creamy balance without overpowering the banana flavor.
- Smoothie Bowl: Blend up a smoothie bowl topped with nuts and seeds for a nutritious side option.
- Ice Cream Float: Create an ice cream float using soda or sparkling water for a fun, fizzy drink that pairs well with dessert.
Common Mistakes to Avoid
Avoiding common mistakes can enhance your experience while making Banana Bars with Brown Butter Icing.
- Using Unripe Bananas: Always use very ripe bananas for the best flavor and moisture. Look for bananas with brown spots.
- Overmixing the Batter: Mix the batter just until combined. Overmixing can lead to tough bars. Aim for a gentle fold.
- Neglecting to Cool Before Icing: Let the bars cool slightly before adding icing. This prevents melting and allows for better texture.
- Skipping Parchment Paper: Line your baking dish with parchment paper. This makes removing the bars much easier after baking.
- Not Measuring Ingredients Accurately: Use proper measuring tools for accuracy. Baking is a science, so precise measurements matter!
