How To Make Key Lime Cake Recipe

This super easy key lime cake is bursting with fresh lime flavor and topped with whipped cream. It’s a delicious summer cake recipe, and if you love key lime pie – then definitely give this recipe a try.
Prep: 30 mins
Cook: 30 mins
Total: 1 hr



  • 1 box cake mix (vanilla, yellow or white)
  • 1/2 cup oil
  • 3 large eggs
  • 3/4 cup sour cream
  • 2 tablespoons lime zest
  • 1/3 cup freshly squeezed lime juice
  • 3 tablespoons lime juice
  • 3 tablespoons sugar
  • 3 tbsp almonds, sliced
  • 2 cups whipped topping (or whipped cream)
  • 2 tablespoon lime zest


  • Preheat the oven to 350F degrees (or 325F degrees if using a glass pan). Grease and flour the bottom and sides of a 9×13 inch pan.
  • Add the cake mix, eggs, sour cream, 1/2 c oil, lime juice and lime zest to a large bowl.
  • Beat with an electric mixer until smooth.
  • Pour the batter into the prepared pan and bake for 27-32 minutes or until an inserted toothpick comes out clean and if you give the pan a gentle nudge the cake doesn’t wobble in the middle.
  • Remove from the oven and allow to cool.
  • In a small saucepan over low heat add the lime juice and sugar. Heat until the sugar dissolves while gently stirring.
  • When the cake is out of the oven, take a small pastry brush or a spoon and brush/drizzle the syrup over top.
  • Spread the whipped topping over top of the cooled cake. Then sprinkle with lime zest.
  • Cut into slices and serve.
