Key Lime Cake Recipe

This Key Lime Cake features a moist vanilla or yellow cake base enhanced with lime zest and juice for a fresh citrus flavor. The cake is brushed with a lime syrup after baking to add extra lime brightness and moisture. A whipped topping finish dusted with lime zest offers a light, creamy contrast to the tangy cake. The combination creates a tender, tangy dessert suitable for warm weather or any time a citrus-flavored cake is desired.

Description

The Key Lime Cake Recipe uses a boxed cake mix combined with sour cream, eggs, vegetable oil, lime juice, and lime zest. Baking in a 9x13 pan results in a dense and moist cake with subtle citrus notes from the lime ingredients integrated into the batter. After baking and cooling, a warm lime syrup made from lime juice and sugar is brushed over the top to infuse additional lime flavor and keep the cake moist.

The final topping consists of whipped topping or whipped cream spread evenly on the cake and sprinkled with fresh lime zest, adding a creamy and tart finish that complements the citrus brightness. The texture is soft with a smooth, luscious topping and a gentle tang throughout.

This cake is great served chilled or at room temperature and slices well for sharing. Preparing the cake a day ahead and adding the whipped topping just before serving helps flavors meld and keeps the topping fresh. Store decorated cakes in the refrigerator to maintain freshness of the whipped topping.

Instructions

Key Lime Cake

  1. Preheat the oven to 350F degrees (or 325F degrees if using a glass pan). Grease and flour the bottom and sides of a 9x13 inch pan. 
  2. Add the cake mix, eggs, sour cream, 1/2 c oil, lime juice and lime zest to a large bowl.
  3. Beat with an electric mixer until smooth.
  4. 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.
  5. Remove from the oven and allow to cool.

Lime Syrup

  1. In a small saucepan over low heat add the lime juice and sugar. Heat until the sugar dissolves while gently stirring.
  2. When the cake is out of the oven, take a small pastry brush or a spoon and brush/drizzle the syrup over top.

Topping

  1. Spread the whipped topping over top of the cooled cake. Then sprinkle with lime zest.
  2. Cut into slices and serve. 

Notes

  • Prepare the cake the day before, drizzle with lime syrup, cover, and keep at room temperature overnight for enhanced flavor and moisture.
  • After decorating with whipped topping or whipped cream, cover and refrigerate to keep the cake fresh.
