Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F and grease an 8x8-inch square baking pan. In a bowl, sift together 1 cup all-purpose flour and 1 tsp baking powder.
  2. Step 2: In a separate large bowl, beat 1/2 cup softened unsalted butter with 3/4 cup granulated sugar until light and fluffy. Add 2 large eggs one at a time, beating well after each. Stir in 1 tsp vanilla extract.
  3. Step 3: Alternate adding the flour mixture and 1/2 cup whole milk to the butter mixture, beginning and ending with flour. Mix until just combined.
  4. Step 4: Pour batter into the prepared pan and bake for 25-30 minutes until a toothpick inserted in the center comes out clean. Let cool completely.
  5. Step 5: Cut the cooled sponge cake into 1-inch cubes.
  6. Step 6: For the icing, whisk together 2 cups powdered sugar and 1/4 cup unsweetened cocoa powder in a bowl. Stir in 2 tbsp unsalted butter and 1/2 cup boiling water gradually until smooth and pourable.
  7. Step 7: Dip each sponge cube into the chocolate icing, letting excess drip off, then roll it in 2 cups shredded coconut. Place on a wire rack to set for 30 minutes before serving.
