Ingredients
Scale
For the Cake:
- 1 box white cake mix (15.25 oz)
- 1 cup buttermilk
- 1/3 cup vegetable oil
- 4 large eggs
- 1 tbsp key lime zest
- 1/3 cup key lime juice (fresh or bottled)
- A few drops green food coloring (optional, for that key lime hue)
For the Key Lime Cream Cheese Frosting:
- 8 oz cream cheese, softened
- 1/2 cup (1 stick) unsalted butter, softened
- 3 ½ – 4 cups powdered sugar
- 2 tbsp key lime juice
- 1 tsp key lime zest
- 1/2 tsp vanilla extract
- Pinch of salt
Instructions
- Preheat oven to 350°F (175°C). Grease and flour two 8-inch or 9-inch round cake pans.
- In a large mixing bowl, combine cake mix, buttermilk, oil, eggs, lime juice, and zest. Beat on medium speed for 2–3 minutes, scraping the bowl as needed. Add green food coloring if desired.
- Pour into pans and bake for 25–30 minutes, or until a toothpick inserted comes out clean. Let cool completely before frosting.
- Make the Frosting:
- Beat cream cheese and butter together until smooth and fluffy.
- Gradually add powdered sugar, mixing well.
- Mix in key lime juice, zest, vanilla, and salt. Beat until creamy. Chill for 15–20 minutes if too soft.
- Assemble the Cake:
- Place one cake layer on a plate or cake stand and spread a thick layer of frosting on top.
- Add the second layer and frost the top and sides.
Notes
- For a stronger lime flavor, add more zest or juice to the frosting.
- Ensure cakes are completely cooled before frosting to prevent melting.
- Store cake in the refrigerator due to the cream cheese frosting.
