Key Lime Cake with Cream Cheese Frosting

A moist, tangy key lime cake made with a lemon cake mix and topped with a rich, homemade cream cheese frosting infused with fresh lime zest and juice.

  • Total Time: 40 minutes
  • Yield: 12 1x

Ingredients

Scale
  • 1 box lemon cake mix
  • 1 1/3 cups vegetable oil
  • 4 large eggs, beaten
  • 1 (3 oz) package lime gelatin
  • 3/4 cup orange juice
  • 8 oz cream cheese, softened
  • 8 oz Cool Whip
  • 2 tsp vanilla extract
  • 1 cup powdered sugar
  • 2 limes, juiced
  • zest from 2 limes

Instructions

  1. Preheat oven to 350°F. Grease and flour two round cake pans.
  2. In a large mixing bowl, blend together cake mix, oil, eggs, gelatin, and orange juice on medium speed until smooth and well blended.
  3. Pour batter into prepared pans and bake according to box mix directions, until a toothpick inserted in the center comes out clean. Let cakes cool completely.
  4. For the frosting, beat cream cheese until smooth. Add Cool Whip, vanilla, powdered sugar, lime juice, and zest. Mix until fluffy and well combined.
  5. Frost the cooled cake layers with the cream cheese frosting. Garnish with additional lime zest if desired.

Notes

For best flavor, use fresh lime juice and zest. If key limes are unavailable, regular limes work well. Store cake in the refrigerator due to the cream cheese frosting.
