Banana Bars with Brown Butter Frosting Ingredients

For the Bars

Butter – Adds moisture and richness; substitute with coconut oil for a dairy-free option.
Sugar – Provides sweetness and structure; try brown sugar for a deeper flavor.
Sour Cream – Contributes to moisture and tenderness; Greek yogurt is a good substitute.
Egg – Acts as a binder to help hold the bars together.
Bananas (very ripe) – Essential for flavor and moisture; they should be overripe for the best results.
Vanilla Extract – Enhances the overall flavor profile.
All-Purpose Flour – Provides structure; can be substituted with a gluten-free flour blend.
Baking Soda – Leavening agent for lift; ensure it’s fresh for proper rise.
Salt – Enhances flavor.

For the Brown Butter Frosting

Butter – Must be browned to add a warm, nutty flavor; this elevates the frosting.
Powdered Sugar – Sweetens and thickens the frosting; whisk until smooth.
Vanilla Extract – Adds a fragrant note that pairs beautifully with the butter.
Milk – Adjusts consistency as needed; add gradually for your desired thickness.

Step‑by‑Step Instructions for Banana Bars with Brown Butter Frosting

Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms up, line an 8×8-inch baking dish with parchment paper, allowing some overhang for easy removal later. This setup helps in creating perfectly shaped Banana Bars with Brown Butter Frosting that come out clean and intact.

Step 2: Cream the Mixture
In a large mixing bowl, cream together the softened butter and sugar until the mixture is light and fluffy, which should take about 3-4 minutes. Add in the sour cream, egg, and mashed ripe bananas, mixing until fully combined. The end result should be a creamy and smooth batter, brimming with banana goodness.

Step 3: Combine Dry Ingredients
Next, sift together the all-purpose flour, baking soda, and salt in a separate bowl. Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Be careful not to overmix; you want a tender crumb in your bars. Once done, spread the batter evenly into the lined baking dish, smoothing the top with a spatula.

Step 4: Bake the Bars
Place the baking dish in the preheated oven and bake for 20 to 25 minutes. The Banana Bars are done when they turn a beautiful golden brown and a toothpick inserted in the center comes out clean. Once baked, remove them from the oven and let them cool for about 10 minutes before carefully lifting them out using the parchment paper.

Step 5: Prepare Brown Butter Frosting
While the bars cool, prepare the brown butter frosting. In a saucepan, melt the butter over medium heat, swirling occasionally until it turns a rich golden brown and emits a nutty aroma, about 5-7 minutes. Watch closely to prevent burning; you want it perfectly browned for that deep flavor.

Step 6: Whisk the Frosting
Transfer the browned butter to a mixing bowl, allowing it to cool slightly. Gradually whisk in the powdered sugar and vanilla extract until smooth. If the frosting is too thick, adding milk a tablespoon at a time will help achieve your desired consistency. Aim for a spreadable texture that will complement the Banana Bars wonderfully.

Step 7: Frost the Bars
After the Banana Bars have cooled for about 10-15 minutes, spread the brown butter frosting generously across the top using a spatula. The warmth of the bars will help the frosting melt slightly, creating a delightful blend of flavors. Let the frosted bars cool completely before slicing them into squares for serving.

Banana Bars with Brown Butter Frosting Recipe FAQs

How do I choose ripe bananas for this recipe?
Absolutely! Look for bananas that are very ripe, with plenty of brown spots. These spots indicate higher sugar content, leading to better flavor and moisture in your Banana Bars with Brown Butter Frosting. Avoid using bananas that are still yellow or, worse, green, as they won’t provide the sweetness you need.

How should I store my Banana Bars?
For optimal freshness, keep your Banana Bars in an airtight container at room temperature for about 3 to 4 days. If you want them to last longer, place them in the fridge for up to a week. Just remember, they can dry out in the fridge, so sealing them well is crucial!

Can I freeze the Banana Bars with Brown Butter Frosting?
Certainly! To freeze, first allow your bars to cool completely. Wrap them tightly in plastic wrap, then place them in a freezer-safe bag. These bars can be frozen for up to 3 months. When you’re ready to enjoy, just thaw them at room temperature or microwave them briefly for a warm treat!

What if my frosting is too thick?
Very! If your brown butter frosting seems too thick to spread, don’t worry. Simply add milk, one tablespoon at a time, until you reach your desired consistency. This will ensure a smooth, spreadable frosting that enhances the bars beautifully.

Do these bars contain common allergens?
Absolutely, the recipe includes eggs and dairy—in the form of butter and sour cream. If you’re concerned about allergies or dietary preferences, feel free to substitute butter with coconut oil for a dairy-free version, and use Greek yogurt or a dairy-free yogurt instead of sour cream. Always check labels to ensure they meet your dietary needs!
