These Brown Butter Banana Bars are a soft and tender dessert that brings together the rich nuttiness of brown butter and the sweet comfort of ripe bananas. The smooth cream cheese frosting makes each bite a little indulgent while still feeling homey and familiar.

This recipe reminds me of the banana cakes my mom used to make when we had a few overripe bananas on the counter. Only this time, the brown butter gives it a cozy twist. Whether it's fall baking season or you just want something sweet any time of year, these bars always hit the spot.

Key Ingredients for Brown Butter Banana Bars
For a full list of ingredients and instructions, see the recipe card below.
- Ripe bananas: use spotty bananas for the best natural sweetness and flavor.
- Brown butter: melted and browned butter gives the bars a warm, toasty flavor that pairs perfectly with banana.
- Cake flour: keeps the texture light and tender. Ideal for a soft dessert bar.
- Buttermilk: adds tang and moisture while activating the baking soda for lift.
- Cream cheese: used in the frosting to add creaminess and balance the sweetness.
- Toasted pecans: a final sprinkle of nuts adds crunch and a buttery finish.

Ingredient Substitutions
- All-purpose flour canreplace cake flour. The bars will just be slightly denser.
- Sour cream or greek yogurt can stand in for buttermilk.
- Walnuts make a great alternative to pecans for a classic banana nut flavor.
Tips for the Best Banana Bars
- Don't overmix. Stir just until combined to keep the bars light.
- Use very ripe bananas: the riper they are, the sweeter and more flavorful your bars will be.
- Cool completely before frosting: this keeps the cream cheese frosting from melting or becoming too thin.
How to Store
Store leftover banana bars in an airtight container in the refrigerator for up to 5 days. To serve, bring them to room temperature.
