Ingredients for Key Lime Cake
The success of a great key lime cake lies in the quality of ingredients. Here’s what you’ll need:
For the Cake:
- 2 1/2 cups all-purpose flour: Flour provides the structure and foundation for the cake.
- 1 1/2 cups granulated sugar: Sugar not only sweetens the cake but also helps to achieve a tender crumb.
- 1 cup unsalted butter, softened: Butter adds richness and moisture, giving the cake its delicate texture.
- 4 large eggs: Eggs are essential for structure and leavening, making the cake rise beautifully.
- 1 cup buttermilk: Buttermilk adds moisture and a subtle tang that complements the lime flavor.
- 1/4 cup fresh key lime juice: The star of the show, key lime juice provides the signature tangy flavor.
- 1 tablespoon key lime zest: Zest intensifies the lime flavor and adds a burst of citrus aroma.
- 1 teaspoon baking powder: Baking powder helps the cake to rise, ensuring it’s light and fluffy.
- 1/2 teaspoon baking soda: Baking soda works with the buttermilk to create a tender crumb.
- 1/2 teaspoon salt: Salt balances the sweetness and enhances the overall flavor.
For the Key Lime Cream Cheese Frosting:
- 8 oz cream cheese, softened: Cream cheese forms the base of this rich and tangy frosting.
- 1/2 cup unsalted butter, softened: Butter ensures the frosting is smooth and easy to spread.
- 3 1/2 cups powdered sugar: Powdered sugar sweetens and thickens the frosting.
- 2 tablespoons fresh key lime juice: This adds a tangy punch to the frosting, echoing the cake’s flavor.
- 1 teaspoon key lime zest: Zest infuses the frosting with a fresh lime aroma.
- 1 teaspoon vanilla extract: Vanilla rounds out the flavor, adding warmth and depth.
Step-by-Step Guide to Making Key Lime Cake
This key lime cake recipe is straightforward and accessible for bakers of all levels. Follow these steps to create a dessert that is both visually stunning and deliciously tangy.
Prepare the Cake Batter
- Preheat the Oven: Set your oven to 350°F (175°C). Grease and flour three 8-inch round cake pans to ensure the cake doesn’t stick.
- Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar. Use an electric mixer to beat the mixture on medium speed for about 3-4 minutes until it becomes light and fluffy. This step is essential as it incorporates air into the batter, ensuring a tender cake.
- Add the Eggs: One by one, add the eggs, beating well after each addition. This process helps to emulsify the eggs with the butter and sugar, creating a smooth batter.
- Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually introduce this dry mixture into the butter mixture, alternating with the buttermilk. Begin and end with the flour mixture, and mix on low speed until just combined. Avoid overmixing, as it can result in a dense cake.
- Infuse with Lime Flavor: Stir in the key lime juice and zest, mixing until the batter is smooth and fully combined. These ingredients add a bright, tangy flavor to the cake.
- Divide and Bake: Evenly divide the batter among the prepared cake pans, smoothing the tops with a spatula. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean. The cakes should be lightly golden and spring back when touched.
- Cool the Cakes: Let the cakes cool in the pans for about 10 minutes. Then, transfer them to a wire rack to cool completely. This step is important to prevent the cakes from becoming soggy.
Make the Key Lime Cream Cheese Frosting
- Cream the Butter and Cream Cheese: In a large mixing bowl, beat together the softened cream cheese and butter until smooth and creamy. This should take about 2-3 minutes on medium speed.
- Add the Powdered Sugar: Gradually add the powdered sugar, one cup at a time, beating on low speed until it’s fully incorporated. Then, increase the speed to medium and continue beating until the frosting is light and fluffy.
- Incorporate Lime Flavor: Add the key lime juice, zest, and vanilla extract, beating until everything is well combined. The frosting should be smooth, with a tangy flavor that complements the cake perfectly.
Assemble the Key Lime Cake
- Layer the Cake: Start by placing one cake layer on a serving plate or cake stand. Spread a generous amount of key lime cream cheese frosting over the top, using a spatula to create an even layer.
- Stack and Frost the Cake: Add the second cake layer on top and repeat the frosting process. Place the third layer and spread the frosting evenly over the top and sides of the cake. Use a bench scraper or an offset spatula for a smooth finish.
- Decorate the Cake: Garnish with additional lime zest, lime slices, or candied lime peels to add a decorative touch that enhances the citrus flavor.
- Chill Before Serving: Refrigerate the cake for at least 1 hour to allow the frosting to set and the flavors to meld. Chilling also makes the cake easier to slice and serve.
Tips for the Perfect Key Lime Cake
Achieving the perfect key lime cake requires a few simple tips and tricks. Follow these guidelines to ensure your cake is a success.
Use Fresh Key Limes
While bottled key lime juice can be convenient, using fresh key limes makes a significant difference in the flavor of your cake. Fresh key lime juice is more vibrant and less bitter than its bottled counterpart, giving your cake a true, authentic citrus flavor.
Don’t Overmix the Batter
Overmixing the cake batter can lead to a dense, tough texture. To avoid this, mix the batter just until the ingredients are combined. This will help keep the cake light and tender.
Chill the Cake Before Serving
Chilling the cake before serving not only helps the frosting to set but also allows the flavors to develop fully. A well-chilled cake is easier to slice and serve, and it tastes even better the next day.
Variations of Key Lime Cake
While the classic key lime cake is a crowd-pleaser, there are plenty of ways to customize it to suit your tastes or the occasion.
Coconut Key Lime Cake
For a tropical twist, consider adding 1/2 cup of shredded coconut to the cake batter. You can also sprinkle toasted coconut on top of the frosting for added flavor and texture. The combination of coconut and lime is a match made in heaven, offering a cake that’s rich, moist, and bursting with tropical flavors.
Key Lime Cupcakes
If you prefer individual servings, transform the key lime cake recipe into cupcakes. Simply divide the batter among cupcake liners and reduce the baking time to 15-18 minutes. These key lime cupcakes are perfect for parties, picnics, or any time you want a portable treat.
Gluten-Free Key Lime Cake
To make a gluten-free version of this cake, substitute the all-purpose flour with a gluten-free flour blend. Be sure to use a blend that contains xanthan gum or add it separately to help bind the ingredients. This gluten-free key lime cake is just as delicious as the original, with all the tangy flavor and tender texture you love.
Frequently Asked Questions About Key Lime Cake
Can I Use Regular Limes Instead of Key Limes?
Regular limes can be used as a substitute if key limes are not available. Key limes have a more intense and slightly floral flavor, but regular limes will still yield a delicious cake. Keep in mind that the flavor will be slightly different, so consider this if you’re aiming for authenticity.
How Long Will Key Lime Cake Last?
This cake can be stored in the refrigerator for up to 5 days. Be sure to cover it tightly with plastic wrap or store it in an airtight container to prevent it from drying out. The cake’s flavor often improves after a day or two, as the lime and cream cheese flavors meld together.
Can I Freeze Key Lime Cake?
Yes, you can freeze key lime cake. To freeze, wrap the unfrosted cake layers tightly in plastic wrap and store them in a freezer-safe bag or container for up to 3 months. Thaw the cake layers in the refrigerator overnight before frosting and serving. If the cake is already frosted, freeze it uncovered until the frosting is firm, then wrap it in plastic wrap and aluminum foil to protect it from freezer burn.
What Pairs Well with Key Lime Cake?
Key lime cake pairs well with a variety of beverages, including iced tea, lemonade, or a glass of crisp white wine. It also makes a great dessert to serve with fresh fruit, such as berries or pineapple, or a scoop of vanilla ice cream. The tangy, sweet flavor of the cake is complemented by the cool, creamy texture of the ice cream.
Can I Make the Cake Ahead of Time?
Yes, you can make the cake ahead of time. The cake layers can be baked, cooled, and wrapped tightly in plastic wrap, then stored at room temperature for up to 2 days or in the refrigerator for up to 5 days. The frosting can also be made ahead of time and stored in the refrigerator for up to 5 days. When you’re ready to assemble the cake, simply bring the frosting to room temperature and proceed as directed.
