Ingredients

  • 12 tablespoons unsalted butter, at room temperature, plus more to grease pans
  • 225 grams gluten-free flour blend about 1 3/4 cup, purchased or homemade see recipe
  • 85 grams almond meal (about 3/4 cup)
  • 1 1/2 tablespoons baking powder
  • 1 teaspoon fine sea salt
  • 322 grams sugar (about 1 1/2 cups)
  • 6 large egg yolks, at room temperature
  • 2 tablespoons vanilla
  • 1 cup buttermilk, at room temperature
  • 1 cup plus 2 tablespoons heavy cream, more as needed
  • 9 ounces bittersweet chocolate, finely chopped
  • 1 tablespoon rum
  • Cherry preserves

Method

  • Heat the oven to 350 degrees, with a rack in the middle.
  • Butter two 9-inch cake pans and line the bottoms with parchment.
  • In a large bowl, whisk together the flour blend, almond meal, baking powder and sea salt until well combined.
  • In a stand mixer with a paddle, beat 12 tablespoons butter for 2 minutes until light and fluffy; add the sugar and beat until light and fluffy, about 8 minutes.
  • With the mixer on medium speed, add the egg yolks, one at a time, stopping to scrape the sides and bottom of the bowl with a rubber spatula.
  • Beat in vanilla.
  • Beat in half the flour mix, then drizzle in half the buttermilk until incorporated.
  • Repeat with the remaining flour mix and buttermilk, scraping down the mixer sides between additions.
  • Bake for 40 to 45 minutes, until golden brown and the top of the cake is firm to the touch.
  • Cool in the pan for 15 minutes.
  • Run a knife around the cake edges and invert onto a cooling rack.
  • Cool to room temperature.
  • Prepare the glaze: In a small heavy saucepan, heat the cream on low heat, to the boiling point, then stir in the chocolate and rum.
  • Stir until melted and smooth, adding more cream if the mixture seems too thick.
  • It should coat the back of a spoon.
  • Turn off the heat and let the glaze cool until just tepid.
  • Spread the cherry preserves over the top of one of the cake layers.
  • Take the other cake layer and stack it upside-down on top of the first layer.
  • Pour the glaze on to the center of the cake, allowing the excess to flow down the sides.
  • Smooth out the top quickly and evenly with a large offset metal spatula.
