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
- tsp salt
- 1 cup whole milk, room temperature
- 1/2 cup fresh key lime juice (or bottled key lime juice)

How to Make Key Lime Cake with Key Lime Cream Cheese Frosting
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper.
Step 2: Make the Cake Batter
- In a large bowl, cream together the unsalted butter and granulated sugar until light and fluffy (about 3-4 minutes).
- Add the eggs one at a time, mixing well after each addition.
- In another bowl, whisk together the all-purpose flour, baking powder, and salt.
- Combine the whole milk, fresh key lime juice, zest, and vanilla extract in a measuring cup.
- Gradually add the dry ingredients to the butter mixture alternately with the milk mixture, starting and ending with dry ingredients. Mix just until combined.
- If desired, stir in a few drops of green food coloring.
Step 3: Bake
Divide the batter evenly between the prepared pans. Bake 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 onto wire racks to cool completely.
Step 4: Make the Frosting
- Beat together the softened cream cheese and unsalted butter until smooth and fluffy.
- Gradually add sifted powdered sugar while mixing well.
- Add key lime juice, zest, and a pinch of salt; beat until fluffy and spreadable. Adjust sweetness or tanginess as needed by adding more juice or sugar.
Step 5: Assemble the Cake
Place one layer of cake on a serving plate. Spread an even layer of frosting on top before adding the second layer. Frost both the top and sides of the cake as desired. Garnish with additional lime zest, slices of lime, or crushed graham crackers to evoke 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 can elevate your baking game. Consider these helpful tips for an exceptional dessert.
- Use Fresh Ingredients: Always opt for fresh key limes when possible; they provide a brighter, more vibrant flavor compared to bottled juice.
- Room Temperature Ingredients: Ensure butter, eggs, and milk are at room temperature; this helps create a smoother batter and better texture.
- Don’t Overmix: Mix just until combined to keep your cake light and airy; overmixing can lead to a dense texture.
- Check Oven Temperature: Use an oven thermometer to ensure your oven is at the correct temperature for even baking.
- Cool Completely: Allow the cake layers to cool completely before frosting; this prevents melting and sliding of the frosting.
- Taste as You Go: Adjust sugar and lime juice in your frosting according to personal preference—taste testing is key!
Best Side Dishes for Key Lime Cake with Key Lime Cream Cheese Frosting
Pairing side dishes with your Key Lime Cake can enhance the overall dining experience. Here are some delightful options:
- Bold Mango Salsa: A fresh mango salsa adds sweetness and contrast, making each bite exciting.
- Tropical Fruit Salad: A mix of seasonal fruits like kiwi, pineapple, and strawberries brightens up the meal.
- Classic Coleslaw: The crunch and tanginess of coleslaw balance well with the creamy cake.
- Cucumber Mint Salad: This refreshing salad provides a cooling effect alongside the zesty cake.
- Grilled Shrimp Skewers: Lightly seasoned shrimp skewers bring in a savory element that complements the sweetness of dessert.
- Lemonade or Iced Tea: A chilled drink like lemonade or iced tea pairs perfectly, enhancing those citrus flavors beautifully.
Common Mistakes to Avoid
Making Key Lime Cake with Key Lime Cream Cheese Frosting can be simple, but there are some common pitfalls to watch out for.
- Overmixing the Batter: This can lead to a tough cake. Mix just until the ingredients are combined for a light texture.
- Incorrect Oven Temperature: Always preheat your oven properly. An inaccurate temperature can cause uneven baking or a sunken cake.
- Using Cold Ingredients: Ensure all your ingredients like butter and eggs are at room temperature. Cold ingredients can affect the batter’s emulsification.
- Skipping the Zest: The zest adds essential flavor. Don’t skip it; instead, use fresh key lime zest for the best taste.
- Not Measuring Ingredients Accurately: Use measuring cups and spoons to ensure correct proportions. Too much or too little can alter the final product.
Refrigerator Storage
- Keep the cake in an airtight container.
- It will last for about 3-5 days in the fridge.
Freezing Key Lime Cake with Key Lime Cream Cheese Frosting
- Wrap individual slices in plastic wrap before placing them in a freezer-safe bag.
- You can freeze it for up to 3 months.
Reheating Key Lime Cake with Key Lime Cream Cheese Frosting
- Oven: Preheat to 350°F (175°C) and warm slices for about 10 minutes.
