Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F. In a bowl, sift together 1 1/2 cups all-purpose flour and 1 1/2 tsp baking powder.
  2. Step 2: In a large mixing bowl, cream 1/2 cup softened unsalted butter and 1 cup granulated sugar until light and fluffy, about 3 minutes. Add 3 large eggs one at a time, beating well after each addition. Stir in 1 tsp vanilla extract.
  3. Step 3: Gradually add the flour mixture alternating with 1/2 cup whole milk, beginning and ending with flour. Mix until just combined.
  4. Step 4: Pour batter into a greased 9x9-inch baking pan and bake for 30-35 minutes until a toothpick inserted comes out clean. Let cool completely.
  5. Step 5: Once cooled, slice the sponge cake horizontally in half. Spread 1/2 cup raspberry jam evenly over the bottom layer, then place the top layer back on.
  6. Step 6: Melt 1 1/2 cups semi-sweet chocolate chips in a heatproof bowl over simmering water, stirring until smooth.
  7. Step 7: Cut the cake into 2-inch squares. Dip each square into the melted chocolate to coat all sides, then immediately roll in 1 1/2 cups toasted coconut flakes. Place on parchment paper to set.
  8. Step 8: Chill for 20 minutes before serving to allow chocolate to firm.
