Banana Layer Cake with Caramel Cream and Pecans

From the kitchen of Carly

Dense, buttery banana cake layered with caramel cream and topped with toasted pecans. The fruit gets folded into a custardy batter that bakes into something surprisingly moist and rich. Not overly sweet, but deeply satisfying.

Banana Layer Cake with Caramel Cream and Pecans

Banana cake gets a caramel upgrade here, the kind that tastes like brown sugar and actual fruit, not extract. Two tender layers with whipped caramel cream between them, the whole thing sturdy enough to slice clean. Pecans scattered on top add crunch and a savory edge that keeps the sweetness honest. The trick is cooking that caramel to exactly 218 degrees, where it's syrupy but still folded into cream without breaking.

  • 2 1/2 cupsugar, divided
  • 6 largeeggs
  • 1 cupplus 2 tablespoons buttermilk
  • 2 smallripe bananas, peeled, cut into 1/4-inch cubes
  • 1 1/2 cupgolden brown sugar
  • 1 smallripe banana, peeled, cut into 1-inch pieces
  • 3 tbspunsalted butter, room temperature

  • 4 1/2 tspfresh lime juice, divided
  • 4 1/2 tspdark rum, divided
  • 1Sea Salt-Roasted Pecans

Instructions

  1. Bring the oven up to 350°F. Butter and flour two 9 inch diameter cake pans with 1 1/2 inch high sides. Sift the flour, baking powder, and sea salt into a medium bowl. In a large bowl, beat the butter and 1 cup of sugar together until well blended. Drop in 2 eggs and beat until smooth. Add the dry ingredients to the butter mixture in 4 alternating additions with the buttermilk in 3 additions. In a separate medium bowl, beat the remaining 4 eggs and 1 1/2 cups of sugar until thick and pale, about 4 minutes. Fold this egg mixture into the batter, then fold in the mashed bananas. Divide the batter between the prepared pans, around 3 1/2 cups in each.

  2. Bake the cakes until a tester pushed into the center comes out clean, about 35 minutes. Move to a rack and cool 15 minutes. Invert the cakes onto the racks and cool completely. (The cakes hold 1 day ahead; wrap in foil and store at room temperature.)

  3. In a food processor, combine the brown sugar, banana, and 3 tablespoons of butter and blend smooth. Pour in 1 1/2 cups of the whipping cream and blend again. Transfer the mixture to a heavy medium saucepan. Whisk over medium heat until the sugar dissolves and the mixture comes to a boil. Clip a candy thermometer to the inside of the pan and continue cooking without stirring or swirling until the temperature reaches 218°F, about 10 minutes. Pour the hot caramel into a bowl and cool to room temperature, whisking occasionally.

  4. Whip the remaining 2 1/4 cups of whipping cream in a large bowl until soft mounds form. Gradually fold in the cooled caramel mixture. Chill until firm enough to spread, about 3 hours.

  5. Slice each cake horizontally into 2 layers. Place 1 layer cut side up on a platter. Drizzle with 1 1/2 teaspoons of lime juice and 1 1/2 teaspoons of rum. Spread 1 1/4 cups of banana cream across the top. Add a second cake layer and drizzle again with 1 1/2 teaspoons of lime juice and 1 1/2 teaspoons of rum. Spread 1 1/2 cups of cream across. Repeat with the third layer, lime juice, rum, and cream. Top with the fourth layer, cut side down, and spread the remaining cream evenly across the top.

  6. Shower the top of the cake with the roasted pecans. (Can be made 1 day ahead; cover with a cake dome and refrigerate.)

Tips from the kitchen

  • Cube the bananas for the batter and puree a separate banana for the caramel. Two different preparations, two different textures in the finished cake.
  • Don't skip chilling the whipped caramel cream for the full 3 hours. It needs to firm up enough to spread without sliding around on the layers.
  • Room temperature butter and eggs are non-negotiable here. Cold ingredients won't emulsify properly and you'll end up with a gritty crumb.
  • Whisk the cooling caramel occasionally as it cools to help it thicken evenly and prevent any graininess from forming.

Variations

  • Skip the rum and lime if you want a cleaner caramel flavor. The cake is rich enough on its own.
  • Toast the pecans yourself with a pinch of smoked salt for more control over the heat and seasoning.
  • Swap dark brown sugar for light brown in the caramel if you prefer something less molasses-forward and more buttery.
  • Make individual layer cakes in smaller pans or even a sheet cake, then cut into squares and assemble the same way.

Make ahead and storage

Wrap the finished cake loosely in plastic and refrigerate for up to 3 days. Not a freezer candidate due to the whipped cream filling, which will weep and separate when thawed.
