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 to prevent sticking.
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 all-purpose flour, baking powder, and salt.
- Combine milk, 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. Start and end with the dry ingredients; mix just until combined.
- If desired, stir in a few drops of green food coloring for extra vibrancy.
Step 3: Bake
Divide the batter evenly between the prepared pans. Bake for 28-32 minutes or until a toothpick inserted in the center comes out clean. Allow cakes to cool in pans for about 10 minutes before turning them out onto 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 powdered sugar while mixing well after each addition.
- Stir in key lime juice, zest, and salt; beat until fluffy and spreadable. Adjust with more juice for tanginess or more sugar for thickness if needed.
Step 5: Assemble the Cake
Place one layer of cake on a serving plate and spread frosting generously on top. Add the second layer and frost the top and sides of the entire cake. For an appealing finish, garnish with additional lime zest, lime slices, or crushed graham crackers to evoke that classic key lime pie feel. Enjoy your delicious creation!

How to Perfect Key Lime Cake with Key Lime Cream Cheese Frosting
Perfecting your Key Lime Cake is easy with these handy tips. Follow these suggestions to ensure your cake turns out great every time.
- Use Room Temperature Ingredients: Allow butter, eggs, and milk to reach room temperature before mixing. This helps achieve a smoother batter and better texture.
- Measure Accurately: Use proper measuring cups for dry and liquid ingredients. Accuracy is key to achieving the right consistency.
- Don’t Overmix: Mix until just combined when adding wet and dry ingredients. Overmixing can result in a dense cake rather than a light and fluffy one.
- Check Oven Temperature: Use an oven thermometer to ensure your oven is at the right temperature. An inaccurate oven can lead to uneven baking.
- Cool Completely: Let the cake layers cool completely before frosting. This prevents the frosting from melting and ensures better application.
- Taste Test Your Frosting: Adjust the sweetness or tanginess of your frosting by adding more powdered sugar or lime juice, depending on your preference.

- Lemon Sorbet: A chilled lemon sorbet offers a refreshing palate cleanser that pairs well with the rich frosting.
- Vanilla Ice Cream: Classic vanilla ice cream provides a creamy counterpart that enhances each bite of cake.
- Spiced Nuts: A bowl of spiced mixed nuts adds crunch and savory notes, creating an interesting flavor combination alongside dessert.
Common Mistakes to Avoid
Baking a Key Lime Cake with Key Lime Cream Cheese Frosting can be delightful, but there are common pitfalls to watch out for. Here are some mistakes to avoid:
-
Skipping room temperature ingredients: Using cold eggs or butter can lead to a dense cake. Make sure all your ingredients are at room temperature for the best texture.
-
Not measuring ingredients accurately: Baking is a science. Use proper measuring cups and spoons to ensure you get the right amounts, especially for flour and sugar.
-
Opening the oven door too soon: This can cause the cake to collapse. Wait until the minimum baking time has passed before checking on your cake.
-
Ignoring cooling times: Letting the cake cool in the pans for too long can make it soggy, while not allowing enough time may result in breakage. Follow cooling instructions carefully.
-
Overmixing the batter: Mixing too much can develop gluten, leading to a tougher cake. Mix just until combined for a light and fluffy texture.
