What is Key Lime Cake?

A key lime cake is a citrus-infused dessert that captures the unique, tangy flavor of key limes, a small and aromatic lime variety that is native to the Florida Keys. This cake has become a popular choice for summer celebrations due to its bright, refreshing flavor and light, moist texture. The cake typically features key lime juice and lime zest, which contribute to its signature tartness.

Compared to regular lime cakes, key lime cakes offer a more intense citrus flavor and often have a slightly denser crumb, which complements the rich frosting. To explore more about the key lime flavor, check out The Kitchn’s Key Lime Cake with Cream Cheese Frosting.

Step-by-Step Key Lime Cake Recipe

Making a key lime cake from scratch is straightforward. Follow these simple steps to create a moist and flavorful dessert.

Ingredients for the Cake:

  • 2 cups of all-purpose flour
  • 1 cup of granulated sugar
  • Three large eggs
  • 1/2 cup of key lime juice (freshly squeezed)
  • Zest from 2 key limes
  • 1 cup of unsalted butter (softened) or vegetable oil
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 cup of milk

Instructions:

  1. Preheat your oven to 350°F (175°C)—grease and flour two round cake pans.
  2. Mix the dry ingredients: In a medium bowl, whisk together the flour, baking powder, and baking soda.
  3. Cream the butter and sugar: In a large bowl, beat the butter and sugar together until light and fluffy.
  4. Add eggs: Beat in the eggs one at a time, then add the lime zest.
  5. Combine wet and dry ingredients: Alternate adding the dry ingredients and milk to the butter mixture, beginning and ending with the dry ingredients. Stir in the key lime juice last.
  6. Bake: Pour the batter into the prepared pans and bake for 25-30 minutes or until a toothpick comes out clean.
  7. Cool: Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

The Perfect Frosting for Key Lime Cake

The frosting is an essential component of any key lime cake. Here are a few popular options for frosting:

  • Cream Cheese Frosting: The tanginess of cream cheese pairs perfectly with the lime flavor. To make it:
    • 8 oz cream cheese (softened)
    • 1/4 cup butter (softened)
    • 2 cups powdered sugar
    • 1 tsp vanilla extract
    • 2 tbsp key lime juice (freshly squeezed)
  • Whipped Cream Frosting: A lighter, fluffier option, ideal if you prefer a less dense topping.
  • Lime Glaze: A simple lime glaze made with powdered sugar and lime juice can add a refreshing, tangy finish.

How to Frost:

Once your cake has cooled, spread the frosting evenly between the layers and on top of the cake. For a simple and elegant finish, you can top the cake with slices of lime or a sprinkle of lime zest.

Common Mistakes to Avoid in Key Lime Cake

When preparing your key lime cake, it’s essential to avoid a few common mistakes to ensure the best results:

  • Using regular limes instead of key limes: Regular limes do not have the same distinctive flavor as key limes and will alter the taste of your cake.
  • Overmixing the batter: Overmixing can result in a dense cake. Mix the ingredients just until they are combined.
  • Incorrect baking time: Make sure to bake the cake at the correct temperature and test for doneness with a toothpick to avoid under or overbaking.
  • Over-sweetening the frosting: It’s important to balance the tartness of the cake with the right amount of sweetness in your frosting.

Serving and Storing Key Lime Cake

How to Serve:

  • Serve the cake chilled or at room temperature for the best flavor.
  • Garnish with fresh lime slices, whipped cream, or additional zest to enhance the visual appeal and flavor.

Storing Tips:

  • Refrigerate any leftover cake for up to 3 days.
  • To freeze the cake, wrap it tightly in plastic wrap and foil. It will stay fresh for up to 2 months.
