  • 2 cups light brown sugar
  • 1 cup granulated sugar, plus more for dusting pan
  • 6 eggs
  • 1 1/4 cups mashed ripe banana (about 2 bananas)
  • 1 1/2 teaspoons vanilla extract
  • 1/2 teaspoon lemon extract
  • 3 cups flour
  • 1 cup sour cream
  • Pinch of kosher salt
  • 1 1/3 cups heavy cream
  • 1 cup honey

  • 1/2 cup Dutch-processed cocoa powder
  • 2 cups semisweet chocolate chips
  • Big pinch of salt

Method

  • Preheat the oven to 325 degrees F.
  • Spray the inside of an angel food cake pan (easier to use) or fluted Bundt pan with nonstick spray.
  • Lightly dust with sugar and set aside.
  • In a stand mixer fitted with the paddle attachment, cream the butter with the sugars until light and fluffy.
  • Add the eggs, one at a time, mixing each one in completely before adding the next.
  • Add the mashed banana and the vanilla and lemon extracts, and beat until completely incorporated.
  • Add a third of the flour to the wet mixture, beating it in completely.
  • Then add a third of the sour cream, beating that in completely.
  • Continue to alternate flour and sour cream until all of it is incorporated.
  • Beat in the salt, then pour the batter into the prepared pan.
  • Bake for 70 to 90 minutes, or until a cake tester comes out clean.
  • Let the cake cool for 5 minutes.
  • Use a small metal spatula to carefully release the cake from the pan.
  • Unmold the cake and let cool before slicing.
  • For the chocolate sauce: Combine the cream, honey, brown sugar, cocoa powder and 1 cup of the chocolate chips in a saucepot over medium-high heat.
  • Bring to a boil, then add the salt and cook, stirring occasionally, until the sauce becomes completely smooth, 5 to 10 minutes.
  • Off the heat, stir in the remaining 1 cup chocolate chips and the butter.
  • Transfer to a jar and set aside until ready to serve.
  • To serve: Preheat a grill or grill pan to medium high.
  • Brush slices of the cake with some melted butter, and grill just until light grill marks appear, 1 to 2 minutes.
  • Remove to a serving platter.
  • Drizzle with chocolate sauce and enjoy.
