Key Lime Cake with Key Lime Cream Cheese Frosting
Ingredients
For the Cake:
2 ½ cups all-purpose flour
2 ½ tsp baking powder
½ tsp salt
1 cup unsalted butter, softened
2 cups granulated sugar
4 large eggs
1 tbsp key lime zest
½ cup fresh key lime juice
1 cup buttermilk
1 tsp vanilla extract
For the Key Lime Cream Cheese Frosting:
8 oz cream cheese, softened
½ cup unsalted butter, softened
4 cups powdered sugar
2 tbsp fresh key lime juice
1 tbsp key lime zest
1 tsp vanilla extract
Preparation
Step 1: Prepare the Cake Batter
Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper.
In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside.
In a large mixing bowl, beat the butter and sugar together until light and fluffy, about 3-5 minutes.
Add the eggs one at a time, mixing well after each addition.
Stir in the key lime zest and vanilla extract.
Alternate adding the dry ingredients and buttermilk, beginning and ending with the flour mixture. Mix until just combined.
Gently fold in the key lime juice, ensuring the batter is smooth and well incorporated.
Step 2: Bake the Cake
Divide the batter evenly between the prepared cake pans.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Remove from the oven and let the cakes cool in the pans for 10 minutes.
Transfer to a wire rack to cool completely before frosting.
Step 3: Prepare the Key Lime Cream Cheese Frosting
In a large mixing bowl, beat the cream cheese and butter together until smooth and creamy.
Gradually add the powdered sugar, mixing well after each addition.
Stir in the key lime juice, zest, and vanilla extract. Mix until the frosting is smooth and fluffy.
Step 4: Assemble the Cake
Place one cake layer on a serving plate and spread a generous amount of frosting on top.
Place the second cake layer on top and spread frosting over the entire cake, including the sides.
Use a spatula to create decorative swirls or smooth out the frosting for a polished look.
Step 5: Garnish and Serve
Garnish the cake with additional key lime zest for extra flavor and visual appeal.
Refrigerate for at least 30 minutes before slicing to allow the frosting to set.
Variation
Lime Coconut Cake: Add ½ cup shredded coconut to the batter for extra texture and tropical flavor.
Lemon-Lime Cake: Replace half of the key lime juice with lemon juice for a citrus twist.
Key Lime Cupcakes: Divide the batter into cupcake liners and bake for 18-20 minutes for a fun, individual treat.
Cooking Note
Use fresh key lime juice for the best flavor. Bottled lime juice may not provide the same bright, tart taste.
If key limes are unavailable, you can substitute with regular limes, but the flavor will be slightly different.
Do not overmix the batter to ensure a light and fluffy texture.
Serving Suggestions
Serve chilled or at room temperature for the best flavor and texture.
Pair with a scoop of vanilla or coconut ice cream for an indulgent dessert.
Garnish with fresh lime slices or edible flowers for an elegant presentation.
