Preparation

  • Preheat your oven to 350°F (175°C).
  • Grease and flour two 8-inch round cake pans.

  • In a separate bowl, beat the softened butter and eggs until creamy.
  • Incorporate the sour cream, key lime juice, zest, and vanilla into the butter and egg mixture.
  • Gradually fold the dry ingredients into the wet mixture until smooth.
  • Pour the batter evenly into the prepared pans.

Baking

  • Allow the cakes to cool completely on a rack.
