The browning of the butter adds a nutty depth that complements the caramelized flavors of the fully ripened bananas, resulting in a moist cake that’s both dense and fluffy.

The frosting features dark chocolate, lending not only a luxurious taste but also a beautiful contrast in color to the golden cake. By adding sour cream to the frosting, a tanginess is introduced that perfectly balances the sweetness, making it irresistible.

Ingredients

Brown Butter Banana Cake with Chocolate Fudge Frosting

1/2 cup salted butter (ideally European style)
2 cups all-purpose flour
3/4 teaspoon baking powder
1/4 teaspoon baking soda
1/4 teaspoon fine sea salt (increase to 1/2 teaspoon if using unsalted butter)
3 large very ripe bananas (mashed, about 1 cup)
1 cup granulated sugar
2 large eggs (at room temperature)
3/4 cup full fat buttermilk
2 tablespoons vegetable oil
1 tablespoon vanilla extract
6 oz 60-70% dark chocolate (finely chopped)
1/4 cup granulated sugar
6 tablespoons Dutch process cocoa powder (sifted)
Pinch fine sea salt
3/4 cup heavy cream
2 tablespoons glucose syrup (or substitute corn syrup or golden syrup)
2 tablespoons butter
1/3 cup sour cream (at room temperature)

Ingredient Notes and Easy Substitutions

Butter: Using European-style butter will give a richer flavor due to its higher fat content. If unavailable, regular salted butter works fine.
Bananas: The riper the bananas, the sweeter and more flavorful your cake will be, so don’t hesitate to use those brown, spotted ones.
Buttermilk: If buttermilk is not available, you can make a quick substitute by adding 1 tablespoon of lemon juice or vinegar to regular milk and letting it sit for 5-10 minutes.
Dark Chocolate: The dark chocolate adds depth to the frosting; however, you can opt for semi-sweet chocolate for a sweeter flavor.

Instructions

Preheat your oven: Start by preheating your oven to 350 degrees F. Prepare a 13-by-9-inch metal baking pan by lightly buttering it and lining it with parchment paper; then lightly butter the parchment as well. This ensures that your cake transfers easily from the pan.
Brown the butter: In a small, heavyweight saucepan (preferably with a light-colored finish), melt the salted butter over medium heat. As it melts, it will become frothy. Continue cooking, stirring occasionally, until the butter solids settle and turn a light golden brown. This process enhances the nutty flavor of the butter. Remove from heat and transfer it to a mixing bowl. Stir in the granulated sugar until the mixture forms a smooth, grainy paste, and let it cool slightly until it’s no longer hot to the touch.
Mix dry ingredients: In another bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
Prepare the bananas: In a separate bowl or a 2-cup glass measuring cup, mash the very ripe bananas until smooth.
Combine wet ingredients: Once the butter-sugar mixture has cooled down to a lukewarm temperature, whisk in the eggs one at a time until fully incorporated. Add the mashed banana and mix well.
Combine wet and dry ingredients: Gradually fold in half of the flour mixture until almost incorporated. Then mix in half of the buttermilk, along with the vegetable oil and vanilla extract. Finally, fold in the remaining flour mixture and then the second half of the buttermilk, mixing until just incorporated.
Bake the cake: Pour the batter into the prepared baking pan. Bake for about 25 minutes or until a toothpick inserted near the center comes out mostly clean with just a few moist crumbs. Once baked, let it cool for 30 minutes in the pan before lifting it out using the parchment paper and transferring it to a cooling rack to cool completely.
Make the fudge frosting: Place the finely chopped dark chocolate in a heat-proof bowl. In a medium saucepan, whisk together the sugar, cocoa powder, and a pinch of sea salt. Add the heavy cream and glucose syrup, followed by the butter. Cook over medium heat, stirring occasionally until the mixture starts to steam and bubble around the edges. It should be thick and paste-like at first but will thin out as you stir.
Combine and cool frosting: Pour the hot cream mixture over the chopped chocolate. Let it sit for 30 seconds before whisking gently until smooth and shiny, then whisk in the sour cream. Allow the frosting to cool at room temperature for about an hour until it’s thick enough to hold soft peaks, stirring every 5-10 minutes.
Frost the cake: Once the cake is completely cool and the frosting has thickened, spread the frosting onto the cake in loose, rustic swirls. You can top it with chocolate crisp pearls or your choice of decorations if desired.
Serve: Slice into squares and enjoy immediately, or refrigerate until you are ready to serve. Leftovers can be stored in an airtight container for up to 5 days.

Expert Tips for the Best Results

Room Temperature Ingredients: Make sure your eggs and sour cream are at room temperature; this helps to create a smooth batter and an even bake.
Don’t Overmix: When folding in the flour, mix until just incorporated to prevent dense cake.
Chocolate Frosting Consistency: Keep a close eye on the frosting as it cools. Too much chilling can cause it to become too stiff to spread.

Variations

Nutty Addition: Add chopped walnuts or pecans to the batter for added crunch.
Spiced Variation: Incorporate a teaspoon of cinnamon or nutmeg into the batter for a warm spice twist.
Fruit Twist: Substitute some of the mashed bananas with unsweetened applesauce or pureed pumpkin for a unique flavor.
Gluten-Free Option: Replace all-purpose flour with a gluten-free flour blend.
Frosting Swaps: Try a cream cheese frosting instead of chocolate for a different flavor profile.

Serving Suggestions

Pair the Brown Butter Banana Cake with a dollop of whipped cream or a scoop of vanilla ice cream for a luxurious dessert experience. Fresh berries or a drizzle of caramel sauce on top can also bring out the flavors beautifully. Enjoy with a cup of coffee or tea for a comforting afternoon treat.

Storage and Reheating

Store leftovers in an airtight container at room temperature for up to 5 days. For longer storage, the cake can be wrapped tightly in plastic wrap and placed in a large freezer bag to freeze for up to 2 months. When ready to enjoy, simply thaw at room temperature or pop it into a microwave for a few seconds to warm it slightly.

Common Mistakes to Avoid

Using Cold Ingredients: Starting with cold eggs or buttermilk can affect the texture; always use room temperature ingredients.
Not Browning Butter Properly: Keep an eye on the butter while browning; burnt butter can lead to a bitter flavor.
Overmixing: Mixing too vigorously can result in a tough cake. Gently fold ingredients instead.
