  • 2 tsp baking powder
  • 1/2 tsp baking soda

  • Preheat the oven to 350F degrees. Grease and flour a 9x13 inch baking pan.
  • In a large bowl beat together the butter and sugar until fluffy.
  • Mix in the vanilla, then the eggs 1 at a time.
  • In a medium bowl whisk together the flour, baking powder, baking soda, and salt.

  • Gently fold in the lemon zest and lemon juice.
  • Pour the batter into the prepared pan and bake for 27-33 minutes or until an inserted toothpick comes out clean.
  • Cool fully. (You can speed up this process by placing the cake in the fridge.

Coconut Frosting

  • Beat the butter until fluffy. Then beat in 4 tablespoons coconut milk, and optional coconut extract.
  • Mix in the powdered sugar about 1 cup at a time until the desired sweetness is reached, adding a little more coconut milk as necessary.
  • Frost the cooled cake and decorate with coconut.
