Vanilla Extract – 1 tsp; enhances the overall flavor, and pure vanilla is best for depth.

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

Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 375°F (190°C). While the oven heats up, line an 8×8 baking dish with parchment paper, allowing enough overhang to easily lift the bars out once baked. This step ensures easy removal and cleanup later.

Step 2: Mix the Wet Ingredients
In a large mixing bowl, cream together 1/4 cup of softened butter, ¾ cup of sugar, ½ cup of sour cream, and 1 egg until the mixture is smooth and well combined. Stir in the 1 cup of mashed very ripe bananas and 1 teaspoon of vanilla extract. You should have a creamy mixture that’s full of rich banana flavor and ready to rise.

Step 3: Combine the Dry Ingredients
In another bowl, whisk together 1 cup of all-purpose flour, ½ teaspoon of baking soda, and ½ teaspoon of salt. Gradually add this dry mixture to the wet ingredients, mixing until just combined. Be careful not to overmix; the batter should be thick and slightly lumpy, indicating the perfect consistency for your Banana Bars.

Step 4: Bake the Bars
Spread the batter evenly into the prepared baking pan, smoothing the top with a spatula. Bake in the preheated oven for 20-25 minutes, or until the edges turn golden brown and a toothpick inserted in the center comes out clean. Your kitchen should smell heavenly as the banana aroma fills the air.

Step 5: Make the Brown Butter Frosting
While the bars are baking, prepare the brown butter frosting. In a saucepan, melt ½ cup of butter over medium heat, swirling occasionally until the butter turns a golden brown and gives off a nutty aroma. This process takes about 5-7 minutes, so stay attentive to prevent burning, ensuring a rich flavor for your frosting.

Step 6: Whisk Together Frosting Ingredients
Remove the browned butter from heat and pour it into a mixing bowl. Whisk in ½ cup of powdered sugar, 1 teaspoon of vanilla extract, and enough milk (about 1½ tablespoons) to achieve a smooth, spreadable consistency. The mixture should be creamy and glossy, ready to generously top your warm banana bars.

Step 7: Frost the Bars
Once the Banana Bars have slightly cooled in the pan, remove them using the parchment overhang and place them on a wire rack or cutting board. Spread the brown butter frosting evenly on top, allowing it to melt slightly into the warm bars. Feel free to frost generously for that decadent finish that everyone will love!

Banana Bars with Brown Butter Frosting Recipe FAQs

What is the best way to select ripe bananas for this recipe?
Absolutely! Look for bananas that are heavily speckled or even almost black; these are perfectly ripe for baking. The more brown spots, the sweeter your banana bars will be, as the sugars in the bananas develop with ripeness. Avoid bananas with dark spots all over or areas that look mushy, as they may be overripe for this recipe.

How should I store the Banana Bars with Brown Butter Frosting?
For optimum freshness, store the bars in an airtight container at room temperature for 3-4 days. If you’re in a warmer climate, refrigerate them for up to a week. When you’re ready to enjoy, let them sit out for a bit to reach room temperature; this will enhance their flavor!

Can I freeze Banana Bars with Brown Butter Frosting? If so, how?
Yes, these bars freeze beautifully! Wrap them tightly in plastic wrap and then seal them in a freezer bag or container to prevent freezer burn. They can be stored for up to 2 months. When you’re ready to indulge, simply transfer them to the fridge to thaw overnight and enjoy them without losing that lovely texture.

What if my frosting is too thick or too thin?
Very common! If your brown butter frosting is too thick, gradually whisk in a little more milk—about a teaspoon at a time—until you achieve a smooth, spreadable consistency. Conversely, if it’s too thin, you can add a bit more powdered sugar to thicken it up. Just keep blending until it’s just right!

Are there dietary considerations I should keep in mind for this recipe?
Definitely! If you need to make this recipe dairy-free, substitute the butter with coconut oil or a plant-based butter alternative. For a non-dairy yogurt, you can use almond, coconut, or soy yogurt for the sour cream. Always check labels for allergens if you’re serving anyone with dietary restrictions!

How can I customize my Banana Bars with Brown Butter Frosting?
The more the merrier! Add mini or semi-sweet chocolate chips to the batter for a decadent twist, or toss in some chopped nuts or shredded coconut for added texture. Don’t hesitate to sprinkle in spices like cinnamon or nutmeg to elevate the flavors further. Enjoy experimenting!
