Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F. In a large bowl, cream 1 cup softened unsalted butter with 1 cup granulated sugar until light and fluffy, about 4 minutes.
  2. Step 2: Add 4 large eggs one at a time, beating well after each addition, then mix in 2 tsp vanilla extract.
  3. Step 3: Sift together 2 cups all-purpose flour and 2 tsp baking powder. Alternately add the flour mixture and 1/2 cup whole milk to the butter mixture, beginning and ending with flour, mixing just until combined.
  4. Step 4: Pour batter into a greased 9x13-inch baking pan and bake for 30-35 minutes until a toothpick comes out clean. Cool completely, then cut into 2-inch cubes.
  5. Step 5: In a saucepan over low heat, melt 2 cups semi-sweet chocolate chips with 1/4 cup unsalted butter, stirring until smooth.
  6. Step 6: Dip each sponge cube into the chocolate ganache, then roll immediately in 2 cups desiccated coconut to coat.
  7. Step 7: Slice each coated cube horizontally and spread 1 teaspoon raspberry jam between layers. Serve chilled or at room temperature.
