Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
• In a medium bowl, whisk together flour, baking powder, and salt.
• In a large bowl, cream together butter and sugar until light and fluffy.
• Beat in eggs one at a time, then stir in buttermilk, key lime juice, and key lime zest.
• Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
• Divide the batter evenly between the prepared pans.
• Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
• Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
• While the cakes cool, prepare the frosting: In a large bowl, beat cream cheese and butter until smooth.
• Gradually beat in powdered sugar, then stir in key lime juice and zest until well combined.
• Once cakes are completely cool, frost the cake as desired.
