Ingredients

For the Cake:

  • 1 cup (2 sticks) unsalted butter, softened
  • 2 cups granulated sugar,
  • 4 large eggs,
  • 2 cups all-purpose flour,
  • 1 tbsp baking powder,
  • 1 tsp salt,
  • 1 cup whole milk (room temperature),
  • 1/2 cup fresh key lime juice (or bottled key lime juice),
  • 1 tbsp key lime zest (or regular lime zest),
  • 1 tsp vanilla extract,
  • Optional: a few drops of green food coloring for a lime hue

For the Key Lime Cream Cheese Frosting:

  • 8 oz cream cheese, softened
  • 1/2 cup (1 stick) unsalted butter, softened
  • 4 cups powdered sugar, sifted
  • 2-3 tbsp key lime juice,
  • 1 tsp key lime zest,
  • Pinch of salt,
  • Optional: a drop of green food coloring for tint

How to Make Key Lime Cake with Key Lime Cream Cheese Frosting

Step 1: Preheat the Oven

Preheat your oven to 350F (175C). Grease and flour two 9-inch round cake pans or line them with parchment paper for easy removal.

Step 2: Make the Cake Batter

  1. In a large bowl, cream together the unsalted butter and granulated sugar until light and fluffy, about 3–4 minutes.
  2. Add eggs one at a time, mixing well after each addition.
  3. In another bowl, whisk together all-purpose flour, baking powder, and salt.
  4. Combine whole milk, key lime juice, zest, and vanilla extract in a measuring cup.
  5. Gradually add dry ingredients to the butter mixture alternately with the milk mixture, starting and ending with dry ingredients. Mix just until combined.
  6. If desired, stir in a few drops of green food coloring.

Step 3: Bake

Divide the batter evenly between prepared pans. Bake for 28–32 minutes or until a toothpick inserted in the center comes out clean. Let cool in pans for about 10 minutes before transferring to wire racks to cool completely.

Step 4: Make the Frosting

Beat together softened cream cheese and unsalted butter until smooth and fluffy. Gradually add sifted powdered sugar while mixing well. Then incorporate key lime juice, zest, and salt; beat until fluffy and spreadable. Adjust consistency with more juice if you prefer tanginess or more sugar for thickness.

Step 5: Assemble the Cake

Place one layer of cake on a serving plate. Spread frosting generously on top before adding the second layer. Frost the top and sides of the entire cake as desired. Garnish with additional lime zest, lime slices, or crushed graham crackers for that classic key lime pie feel. Enjoy!

How to Serve Key Lime Cake with Key Lime Cream Cheese Frosting

Serving your Key Lime Cake with Key Lime Cream Cheese Frosting can elevate any occasion. This zesty dessert pairs well with various accompaniments, enhancing its refreshing citrus flavor and creamy texture.

With Fresh Fruit

  • Fresh berries: A mix of strawberries, blueberries, and raspberries adds a burst of color and flavor.
  • Slices of lime: Thin lime slices can add an extra zing and complement the cake’s citrusy notes.

Alongside Whipped Cream

  • Lightly sweetened whipped cream: This adds a luscious creaminess that balances the tanginess of the key lime frosting.
  • Flavored whipped cream: Consider adding vanilla or coconut extract for a unique twist.

Paired with Ice Cream

  • Coconut ice cream: The creamy texture and tropical flavor work harmoniously with the key lime.
  • Vanilla bean ice cream: A classic choice that allows the cake’s flavors to shine through.

Garnished with Nuts

  • Crushed pistachios: Their crunchiness adds texture and a pop of color.
  • Toasted coconut flakes: These provide a delightful chewiness and enhance the tropical vibe.

How to Perfect Key Lime Cake with Key Lime Cream Cheese Frosting

Perfecting your Key Lime Cake is all about attention to detail. Here are some tips to ensure your cake turns out wonderfully every time.

  • Use room temperature ingredients: This helps create a smoother batter and ensures even mixing, leading to a lighter cake.
  • Sift dry ingredients: Sifting flour and baking powder together removes lumps and ensures even distribution in the batter.
  • Don’t overmix: Mix just until combined to keep the cake light and fluffy. Overmixing can lead to a dense texture.
  • Cool completely before frosting: Allowing the cake layers to cool thoroughly prevents melting the frosting, resulting in a neater presentation.
  • Adjust frosting consistency: If your frosting is too thick, add more key lime juice; if it’s too thin, incorporate more powdered sugar until you reach your desired thickness.

Best Side Dishes for Key Lime Cake with Key Lime Cream Cheese Frosting

Complement your Key Lime Cake with delicious side dishes for an unforgettable meal experience. Here are some great options:

  1. Coconut Rice: Fluffy rice cooked in coconut milk adds a subtle sweetness that pairs well with key lime flavors.
  2. Grilled Pineapple: Charring pineapple enhances its natural sweetness, making it a perfect accompaniment for this tangy dessert.
  3. Tropical Fruit Salad: A mix of mango, papaya, and kiwi provides freshness that brightens up any plate.
  4. Spinach Salad: Tossed with citrus vinaigrette, this salad offers a refreshing contrast to the rich frosting.
  5. Quinoa Salad: A light quinoa salad mixed with herbs and citrus dressing brings a wholesome touch to your dessert table.
  6. Zucchini Fritters: Savory fritters add crispy texture while not overpowering the sweet flavors of the cake.

Common Mistakes to Avoid

Baking a Key Lime Cake with Key Lime Cream Cheese Frosting can be delightful, but it’s easy to make mistakes. Here are some common pitfalls to watch out for:

  • Not measuring ingredients accurately: Always use the correct measuring cups and spoons to ensure your cake turns out perfectly.
  • Using cold ingredients: Make sure your butter, eggs, and milk are at room temperature for better mixing and a fluffier texture.
  • Overmixing the batter: Mix just until combined to avoid a dense cake. Overmixing can lead to tough results.
  • Ignoring oven temperature: Always preheat your oven and consider using an oven thermometer for accuracy. An incorrect temperature can affect baking time.
  • Skipping the cooling step: Let the cake cool completely before frosting. This prevents the frosting from melting and sliding off.

Storage & Reheating Instructions

Refrigerator Storage

  • Store in an airtight container for up to 5 days.
  • Place parchment paper between layers if stacking to prevent sticking.

Freezing Key Lime Cake with Key Lime Cream Cheese Frosting

  • Wrap each layer tightly in plastic wrap and foil for up to 3 months.
  • Thaw overnight in the refrigerator before serving.
