Ingredients

Cake

  • 4 large eggs
  • 1/2 c unsalted butter melted
  • 1 c whole milk
  • 1 box yellow cake mix
  • 2 tbs shredded coconut sweetened or unsweetened

Crunch Topping

  • 2 tbs desiccated coconut sweetened or unsweetened
  • Butter for greasing the pan

Glaze

  • 2 c powdered sugar
  • 4 tbs unsalted butter melted
  • 4 tbs milk or heavy cream
  • 1/2 tsp vanilla extract
  • 1/2 tsp lemon extract

Instructions

  • Preheat the oven to 350°F.
  • In a large mixing bowl, whisk together the eggs, whole milk, and melted butter until smooth and fully combined.
  • Add the yellow cake mix and shredded coconut to the bowl. Stir gently until the batter is evenly mixed and no dry streaks remain.
  • Thoroughly grease a large bundt pan with butter.
  • Sprinkle the desiccated coconut evenly inside the greased bundt pan, coating the interior surface as completely as possible.
  • Pour the cake batter into the prepared bundt pan and smooth the top if needed.
  • Bake for 40 to 45 minutes, or until a toothpick inserted into the center of the cake comes out clean.
  • Remove the cake from the oven and allow it to cool before removing it from the bundt pan.
  • While the cake cools, prepare the glaze. In a small bowl, whisk together the powdered sugar, melted butter, milk or heavy cream, vanilla extract, and lemon extract until smooth.
  • Once the cake has cooled and been removed from the pan, drizzle the glaze evenly over the top.
  • If desired, garnish with additional coconut flakes.
  • Allow the glaze to set for 15 to 20 minutes before serving.
