Key Lime Cake Taste the Tropics in Every Slice

Instructions:

1. Preheat oven to 350°F (175°C). Grease and flour two 9-inch cake pans, then line the bottoms with parchment paper rounds.
2. Whisk together flour, baking powder, baking soda, and salt in a medium bowl.
3. In a large bowl, cream together softened butter and sugar until light and fluffy.
4. Beat in eggs one at a time, then stir in vanilla extract.
5. Gradually add the dry ingredients to the wet ingredients, alternating with sour cream, beginning and ending with the dry ingredients. Mix until just combined.
6. Stir in Key lime juice and zest.
7. Divide batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
8. Let cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
9. Combine lime juice and sugar in a microwave safe bowl and microwave for 30 seconds. Stir until sugar is dissolved.
10. While cakes are cooling, make the frosting. In a large bowl, beat cream cheese and butter until smooth and creamy. Gradually add powdered sugar, beating until light and fluffy. Stir in Key lime juice and zest.
11. Once cakes are completely cool, soak cakes with key lime mixture, spread frosting between the cake layers and over the top and sides of the cake.
12. Chill the cake for at least 30 minutes before serving.
