Ingredients

• 2 cups all-purpose flour
• 2 teaspoons baking powder
• 1 teaspoon salt
• 1/2 cup butter, softened
• 1 1/2 cups sugar
• 2 eggs
• 1/2 cup sour cream
• 1/4 cup Key lime juice
• 1 teaspoon grated lime zest
• 2 cups powdered sugar
• 1/4 cup butter, melted
• 3 to 4 tablespoons Key lime juice

Directions

1. Preheat the oven to 350 degrees F. Grease and flour two 9-inch round cake pans.
2. In a medium bowl, sift together the flour, baking powder, and salt; set aside.
3. In a large bowl, cream together the butter and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the sour cream and Key lime juice. Beat in the sifted ingredients alternately with the lime zest.
