Ingredients

Scale
  • 1/2 cup (115g) unsalted butter, browned
  • 3/4 cup (150g) packed brown sugar
  • 2 tbsp (30ml) light corn syrup (can substitute with honey)
  • 1/4 cup (60ml) heavy cream, warmed
  • 2 tbsp (30ml) dark rum, optional
  • Pinch of salt
  • 3 medium ripe bananas, sliced
  • 2 tbsp (28g) butter, melted
  • 2 tbsp (25g) brown sugar
  • 1 1/2 cups (190g) all-purpose flour
  • 1 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 3/4 cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • 3/4 cup (180ml) buttermilk, room temperature (or milk + 1 tsp white vinegar)
  • 1 tsp vanilla extract
  • 6 tbsp (85g) unsalted butter, melted and cooled slightly

Instructions

  1. Prepare the Brown Butter Caramel: In a medium saucepan over medium heat, melt the butter. Stir constantly as it foams and turns golden brown, about 4-6 minutes, until nutty and fragrant. Immediately add brown sugar and corn syrup, stirring until combined. Slowly whisk in warmed heavy cream and rum (if using). Cook for 2-3 minutes until slightly thickened. Remove from heat and set aside.
  2. Caramelize the Bananas: Preheat oven to 350°F (175°C). Toss sliced bananas with melted butter and brown sugar until evenly coated. Arrange bananas in the bottom of a 9-inch round cake pan or cast iron skillet, overlapping slightly but not squashed.
  3. Pour half of the brown butter caramel over the bananas, spreading gently to coat evenly.
  4. Mix Dry Ingredients: In a large bowl, sift together flour, baking powder, baking soda, and salt. Set aside.
  5. Mix Wet Ingredients: In another bowl, whisk granulated sugar and eggs until pale and slightly thickened, about 2-3 minutes. Add buttermilk, vanilla extract, and melted butter, mixing until smooth.
  6. Combine Batter: Gradually fold dry ingredients into wet mixture using a rubber spatula. Mix until just combined to avoid toughening the cake.
  7. Assemble the Cake: Pour batter gently over the caramelized bananas in the pan, spreading evenly.
  8. Bake: Bake in preheated oven for 40-45 minutes, or until a toothpick inserted in the center comes out clean. The top should be golden and edges bubbly with caramel.
  9. Cool and Invert: Let cake cool in pan for 15 minutes. Run a knife around edges to loosen. Place a serving plate over the pan and carefully invert the cake. Gently shake pan to release.
  10. Serve: Spoon remaining brown butter caramel over the warm cake. Slice and serve immediately, optionally with vanilla ice cream.

Notes

Stir constantly when browning butter to avoid burning. Use ripe bananas with brown spots for best flavor. Let cake cool before inverting to allow caramel to set. Warm caramel slightly if too thick before drizzling. Avoid overmixing batter to keep cake tender.
