A Key Lime Cake is a delightful dessert that offers a burst of tropical flavor with every bite. This cake, inspired by the famous Key Lime Pie, is known for its tangy, citrusy taste combined with a rich, moist crumb. Whether you’re a seasoned baker or a beginner, this guide will walk you through the steps to create a delicious Key Lime Cake, along with variations and serving tips.
Understanding the Unique Flavor of Key Limes
Key limes are smaller and more aromatic than regular limes, with a distinct tartness that makes them ideal for desserts like this cake. If you can find them, they’re worth the effort for their unique flavor. However, if Key limes are unavailable, regular limes (often called Persian limes) can be used as a substitute. The result will still be delicious, though slightly less tart (The Kitchn).

Ingredients for the Key Lime Cake
To achieve the perfect balance of sweet and tart, you’ll need the following ingredients:
- Flour: All-purpose flour provides structure and stability to the cake.
- Sugar: Granulated sugar adds the necessary sweetness to balance the tartness of the limes.
- Eggs: These add richness and help bind the cake together.
- Sour Cream: Adds moisture and a slight tang, contributing to the cake’s tender crumb.
- Vegetable Oil: Helps keep the cake moist without making it too dense.
- Key Lime Juice: The star ingredient, providing that signature tart flavor.
- Lime Zest: Enhances the lime flavor and adds a vibrant aroma.
- Baking Powder and Baking Soda: These leavening agents ensure the cake rises well and has a light texture (Simply Recipes) (Modern Honey).

Step-by-Step Instructions
1. Preparing the Cake Batter
- Mix the Dry Ingredients: In a bowl, combine flour, baking powder, baking soda, and salt. Set aside.
- Combine the Wet Ingredients: In another bowl, mix the sour cream, Key lime juice, and vegetable oil.
- Beat the Eggs and Sugar: In a large mixing bowl, beat the eggs and sugar until light and fluffy. This step is crucial for creating a tender cake crumb.
- Incorporate the Ingredients: Gradually mix the dry and wet ingredients into the egg mixture, alternating between the two. This method ensures a smooth batter and prevents overmixing, which can lead to a dense cake (Simply Recipes) (Baking A Moment).
2. Baking the Cake Layers
- Prepare the Pans: Grease and line three 8-inch round cake pans with parchment paper. Divide the batter evenly among the pans.
- Bake: Preheat your oven to 350°F (175°C). Bake the cakes for 18-22 minutes, or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for about 15 minutes before transferring them to a wire rack to cool completely.
3. Making the Key Lime Cream Cheese Frosting
- Cream the Ingredients: Beat softened cream cheese and butter together until smooth. Add Key lime juice, lime zest, and powdered sugar, beating until the frosting is light and fluffy.
- Adjust the Consistency: If the frosting is too thick, add a little more lime juice. If it’s too thin, add more powdered sugar until you reach the desired consistency (The Kitchn) (Modern Honey).
Assembling the Key Lime Cake
Layering and Frosting the Cake
- Frosting Between Layers: Spread an even layer of frosting between each cake layer.
- Final Coating: Use the remaining frosting to cover the top and sides of the cake, smoothing it out for a polished look.
Decorating Tips
- Garnishes: Simple garnishes like lime zest or thin lime slices can elevate the cake’s presentation, making it as visually appealing as it is delicious.
Variations and Serving Suggestions
Key Lime Cupcakes
- Adapt the cake recipe into cupcakes by dividing the batter into a lined cupcake pan. Bake at 350°F for 15-18 minutes, and top with Key lime cream cheese frosting for a portable version of this tropical treat.
Key Lime Bundt Cake
- For a more rustic presentation, bake the batter in a bundt pan. Adjust the baking time to 40-45 minutes. The bundt shape adds an elegant touch and makes slicing easier (Baking A Moment).
Alternative Frostings and Fillings
- Consider using whipped cream or buttercream frosting for a different texture. Fillings like lime curd or citrus marmalade can add an extra layer of flavor (Baking A Moment).
Serving Suggestions
- Serve the cake with fresh berries or a dollop of whipped cream. For a refreshing contrast, pair it with a scoop of vanilla ice cream.
Frequently Asked Questions (FAQs)
Can I use regular limes instead of Key limes?
Yes, regular limes can be used, though the flavor will be slightly less tart. Key limes provide a more intense citrus flavor that is characteristic of this cake (The Kitchn).
How do I keep my cake layers moist?
Incorporate ingredients like sour cream or oil to maintain moisture. Proper storage is also key—wrap the cake tightly in plastic wrap or parchment paper to prevent it from drying out (Simply Recipes).
Can I make the cake batter ahead of time?
It’s best to bake the cake as soon as the batter is prepared. The baking soda begins to activate once the wet ingredients are mixed in, so delaying baking can affect the cake’s rise and texture (Baking A Moment).
How should I store the Key Lime Cake?
Store the cake in the refrigerator for up to four days. Wrap it tightly in plastic wrap or parchment paper to maintain its moisture and freshness (Simply Recipes).
