Ingredients

Lemon Cake

  • 1 box yellow or lemon cake mix
  • ½ cup butter, melted
  • ½ cup milk
  • ½ cup sour cream
  • 3 large eggs
  • 2 tablespoons fresh lemon juice
  • 1 tablespoon lemon zest

Instructions

Make the Cake

  • Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or a 9x13-inch pan.
  • In a large bowl, mix the cake mix, melted butter, milk, sour cream, eggs, lemon juice, lemon zest, vanilla extract, and coconut extract until smooth.
  • Divide batter evenly between the cake pans (or pour into the 9x13 pan).
  • Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
  • Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

Make the Frosting

  • In a large bowl, beat the butter with an electric mixer until smooth and creamy.
  • Gradually add the powdered sugar, mixing on low speed.
  • Add coconut milk, vanilla extract, and coconut extract and beat until fluffy.

Assemble the Cake

  • Place one cake layer on a serving plate. Spread a layer of frosting on top.
  • Add the second cake layer and frost the top and sides evenly.
  • Sprinkle the shredded coconut over the top and gently press it into the sides.
