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)

- Optional: a few drops of green food coloring for a lime hue
For the Key Lime Cream Cheese Frosting:

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
- In a large bowl, cream together the softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
- Add eggs one at a time, mixing well after each addition.
- In another bowl, whisk together flour, baking powder, and salt.
- Combine whole milk, key lime juice, zest, and vanilla extract in a measuring cup.
- Gradually add dry ingredients to the butter mixture alternately with the milk mixture, beginning and ending with dry ingredients. Mix just until combined.
- If desired, stir in a few drops of green food coloring for added hue.
Step 3: Bake
Divide the batter evenly between the prepared pans. Bake in preheated oven for 28-32 minutes or until a toothpick inserted into the center comes out clean. Allow cakes to cool in pans for about 10 minutes before transferring them to wire racks to cool completely.
Step 4: Make the Frosting
In a mixing bowl, beat together softened cream cheese and butter until smooth and fluffy. Gradually add sifted powdered sugar while mixing well. Incorporate key lime juice, zest, and salt; beat until fluffy and spreadable. Adjust consistency by adding more juice for tanginess or more sugar for thickness.
Step 5: Assemble the Cake
Place one layer of cake on a serving plate and spread frosting generously on top. Add the second layer on top of that and frost both the top and sides of the entire cake. For an extra touch, garnish with additional lime zest, lime slices, or crushed graham crackers for that classic key lime pie feel.

How to Perfect Key Lime Cake with Key Lime Cream Cheese Frosting
Perfecting your Key Lime Cake with Key Lime Cream Cheese Frosting is all about attention to detail and technique. Follow these tips for the best results.
-
Use Room Temperature Ingredients: Ensure butter, eggs, and milk are at room temperature for better mixing and fluffiness.
-
Sift Dry Ingredients: Sifting flour and powdered sugar can help avoid lumps in your batter and frosting, resulting in a smoother texture.
-
Don’t Overmix: Mix just until combined when adding dry ingredients to keep your cake light and fluffy. Overmixing can create a dense texture.

Common Mistakes to Avoid
Baking a Key Lime Cake with Key Lime Cream Cheese Frosting can be a delightful experience, but avoiding common pitfalls will help you achieve the best results.
-
Skipping Room Temperature Ingredients: Using cold ingredients can prevent the batter from mixing well. Always allow butter, eggs, and milk to come to room temperature before starting.
-
Overmixing the Batter: Mixing too much can lead to a dense cake. Mix until just combined and avoid beating after adding the flour mixture.
-
Ignoring Oven Temperature: Each oven is different; relying solely on the dial can lead to undercooked or burnt cake. Use an oven thermometer for accuracy.
-
Not Measuring Ingredients Correctly: Accurate measurements are crucial in baking. Use a kitchen scale or proper measuring cups for precision.
-
Frosting Too Early: Frosting a warm cake can cause it to melt. Let your cake cool completely on wire racks before applying the frosting.
-
Neglecting Garnishes: Missing out on garnishes can make your cake visually unappealing. Consider adding lime zest or crushed graham crackers for an attractive finish.
