Key Lime Cake

Ingredients:

  • For the Cake:
    • 2 cups all-purpose flour
    • 1 ½ cups granulated sugar
    • ½ cup unsalted butter, softened
    • 1 cup buttermilk, at room temperature
    • 3 large eggs, at room temperature
    • 1 tablespoon key lime zest (about 2-3 limes)
    • ½ cup key lime juice (freshly squeezed)
    • 1 tablespoon baking powder
    • ½ teaspoon baking soda
    • ½ teaspoon salt
    • 1 teaspoon vanilla extract
  • For the Key Lime Frosting:
    • 1 cup unsalted butter, softened
    • 4 cups powdered sugar
    • ¼ cup key lime juice (freshly squeezed)
    • 1 tablespoon key lime zest
    • 1 teaspoon vanilla extract
    • Pinch of salt
  • For Garnish:
    • Key lime slices
    • Additional key lime zest
    • Whipped cream (optional)

Preparing the Cake Batter

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. This will ensure that your cakes come out easily once baked.
  2. In a large mixing bowl, cream together the softened butter and granulated sugar using an electric mixer on medium speed. Beat for about 3-4 minutes until the mixture is light and fluffy.
  3. Add the eggs one at a time, mixing well after each addition. This helps to incorporate air into the batter, making your cake light and airy.
  4. Mix in the vanilla extract and key lime zest. The zest will add a wonderful fragrance and flavor to your cake.
  5. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. This ensures that the leavening agents are evenly distributed throughout the flour.
  6. Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk. Start and end with the flour mixture. Mix until just combined; be careful not to overmix, as this can lead to a dense cake.
  7. Finally, fold in the key lime juice gently. This will give your cake that signature tangy flavor that key lime is known for.

Baking the Cake

  1. Divide the batter evenly between the two prepared cake pans. Use a spatula to smooth the tops for even baking.
  2. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Keep an eye on them, as oven temperatures can vary.
  3. Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes. Then, carefully turn them out onto a wire rack to cool completely. This step is crucial; if you frost the cakes while they are still warm, the frosting will melt and slide off.

Making the Key Lime Frosting

  1. While the cakes are cooling, let’s prepare the frosting. In a large mixing bowl, beat the softened butter with an electric mixer on medium speed until creamy.
  2. Gradually add the powdered sugar, mixing on low speed until combined. This helps to prevent a sugar cloud from forming!
  3. Once the sugar is incorporated, add the key lime juice, key lime zest, vanilla extract, and a pinch of salt. Beat on medium speed until the frosting is light and fluffy, about 3-5 minutes. If the frosting is too thick, you can add a little more key lime juice or a splash of milk to reach your desired consistency.

Assembling the Cake

  1. Once the cakes are completely cool, place one layer on a serving plate or cake stand. This will be the base layer.
  2. Spread a generous amount of key lime frosting on top of

Key Lime Cake

Conclusion:

In summary, this Key Lime Cake is an absolute must-try for anyone who loves a refreshing and zesty dessert. The combination of tangy key lime juice and creamy frosting creates a delightful balance that will leave your taste buds dancing with joy. Whether you’re serving it at a summer barbecue, a birthday celebration, or simply enjoying a slice with your afternoon tea, this cake is sure to impress your family and friends. For a fun twist, consider adding a layer of coconut or a sprinkle of crushed graham crackers on top of the frosting to mimic the classic key lime pie crust. You could also experiment with different citrus flavors, like lemon or orange, to give it your own unique spin. The possibilities are endless!
