Ingredients

2 ¼ cups cake flour
1 ½ cups granulated sugar
1 tablespoon baking powder
½ teaspoon baking soda
½ teaspoon salt
1 cup buttermilk
¼ cup fresh lime juice
2 tablespoons lime zest
2 teaspoons clear vanilla extract
½ cup vegetable oil
4 egg whites
Lime wedges (for garnish)
Graham crackers (for garnish)
8 ounces cream cheese, room temperature
½ cup unsalted butter, room temperature
1 teaspoon clear vanilla extract
2 teaspoons lime zest
½ teaspoon salt
4 cups powdered sugar

Instructions

For the Cake:

Preheat your oven to 350°F (175°C) and prepare two 8-inch cake pans by greasing them and lining the bottoms with parchment paper.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
Add buttermilk, lime juice, lime zest, vanilla extract, and vegetable oil to the dry ingredients. Beat until fully combined.
In a separate bowl, whip the egg whites until they form medium stiff peaks. Gently fold them into the batter until just combined.
Divide the batter evenly between the prepared cake pans and bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool completely.
Once cooled, wrap each cake in plastic wrap and chill in the fridge for at least 2 hours or overnight.
Frost the chilled cakes with lime cream cheese frosting and decorate with fresh lime wedges and crushed graham crackers. Store in the fridge until ready to serve.

For the Lime Cream Cheese Frosting:

In the bowl of a mixer, beat the cream cheese and butter together until smooth.
Add vanilla extract, lime zest, salt, and powdered sugar to the bowl. Mix on low speed until the powdered sugar is moistened, then increase the speed to medium-high and beat until the frosting is smooth and fluffy, about 2-3 minutes.
Use the frosting immediately to frost the cake, or store it in the refrigerator and let it come to room temperature before using.

Notes

Serving Tips:

Presentation is Key: Before serving, garnish your Key Lime Cake with fresh lime wedges and a sprinkle of crushed graham crackers for a visually appealing touch.
Slice with Care: Use a sharp knife dipped in hot water and wiped clean between slices to ensure clean, smooth cuts through the cake layers.
Pair with a Refreshing Beverage: Accompany your slice of Key Lime Cake with a chilled glass of iced tea, lemonade, or even a tropical fruit smoothie for the ultimate flavor experience.
Serve at the Right Temperature: For the best taste and texture, let the cake sit at room temperature for about 10-15 minutes before serving to allow the flavors to fully develop.
Add a Dollop of Whipped Cream: For an extra indulgent treat, serve each slice with a dollop of freshly whipped cream on top, adding a creamy contrast to the tangy lime flavor.

Storage Tips:

Refrigeration is Key: Due to the cream cheese frosting, store any leftover Key Lime Cake in an airtight container in the refrigerator to maintain its freshness and prevent spoilage.
Properly Wrap for Longer Storage: To prolong its shelf life, tightly wrap individual slices of cake in plastic wrap or aluminum foil before storing them in the fridge.
Consume Within a Few Days: While Key Lime Cake can be stored in the refrigerator for up to 3-4 days, it’s best enjoyed within the first couple of days for optimal taste and texture.
Avoid Freezing the Frosted Cake: While unfrosted cake layers can be frozen for longer storage, it’s not recommended to freeze Key Lime Cake once it’s been frosted, as the texture of the frosting may change upon thawing.
Allow to Come to Room Temperature Before Serving: When ready to enjoy leftover cake, remove it from the refrigerator and let it sit at room temperature for 15-20 minutes before serving to allow the frosting to soften slightly and the flavors to mingle.
