You know when you wake up with a recipe idea and it just will not leave you alone? Yeah… that was me with this cake. I fully had other things to do today, but this salted caramel brown butter banana cake said absolutely not. And honestly… I’m so glad I listened. Because WOW. This cake is next level. We’re talking super moist banana cake, nutty brown butter, silky cream cheese frosting, and layers of salted caramel that make every bite feel like a little moment. I’m known for banana bread… but today banana cake officially entered the chat, and I fear she might be staying.
Ingredient Breakdown
For the Banana Cake
-
Unsalted Butter (¾ cup, browned)
This is where the magic starts. Browning the butter adds a rich, nutty depth that completely elevates the flavor of the cake. It’s one extra step that makes a huge difference. -
Light Brown Sugar (1 cup)
Brown sugar brings moisture and a subtle caramel flavor that pairs perfectly with bananas and brown butter. It helps create that soft, tender crumb. -
Granulated Sugar (½ cup)
Balances the brown sugar and adds structure. It also helps the cake rise properly and gives a light sweetness. -
Eggs (3 large)
Eggs provide structure, richness, and stability to the cake. Make sure they’re room temperature so everything mixes smoothly. -
Vanilla Extract (1 tablespoon)
Enhances all the flavors in the cake and adds that warm bakery-style aroma. -
Sour Cream (½ cups)
This is key for moisture. It makes the cake super soft and gives a slight tang that balances the sweetness. -
Whole Milk (1 cup)
Adds additional moisture and helps loosen the batter so it bakes evenly. -
Bananas (4, mashed)
The star of the show. Overripe bananas bring natural sweetness, flavor, and that iconic banana texture. -
All-Purpose Flour (3 cups)
Provides the structure of the cake. Make sure to measure properly so the cake stays soft and not dense. -
Baking Powder (2 teaspoons)
Helps the cake rise and keeps it light and fluffy. -
Cinnamon (1 teaspoon)
Adds a warm, cozy flavor that enhances the banana and brown butter. -
Salt (½ teaspoon)
Balances sweetness and enhances all the other flavors.
For the Salted Caramel
-
Granulated Sugar (1 cup)
Melts down to create the base of your caramel. It transforms into that deep amber color and flavor. -
Unsalted Butter (6 tablespoons)
Adds richness and helps create that smooth caramel texture. -
Heavy Cream (½ cup)
Makes the caramel silky and pourable. It also tones down the intensity of the sugar. -
Salt (1 teaspoon)
The finishing touch that makes everything pop. It balances sweetness and gives that classic salted caramel flavor.
For the Brown Butter Cream Cheese Frosting
-
Cream Cheese (12 oz, room temp)
Gives the frosting that tangy, rich flavor that pairs perfectly with the sweet cake. -
Unsalted Butter (¾ cup, browned)
Adds depth and a slightly nutty flavor that makes this frosting unreal. -
Vanilla Extract (1 teaspoon)
Rounds out the frosting with a warm, sweet flavor. -
Heavy Cream (2 tablespoons)
Helps create a smooth, spreadable consistency. -
Powdered Sugar (to desired consistency)
Sweetens and thickens the frosting. Add gradually until you reach your perfect texture.
Optional Topping
-
Banana (1, sliced)
Adds a beautiful and flavorful finishing touch. -
Butter (2 tablespoons)
Used to caramelize the bananas. -
Brown Sugar (2 tablespoons)
Creates that golden, glossy caramelized coating on the bananas.

Swap sour cream with Greek yogurt for a similar texture
-
