Essential Tools and Equipment
- Mixing bowls
- Electric mixer
- Measuring cups and spoons
- Rubber spatula
- 9-inch round cake pans
- Parchment paper (optional)
- Cooling rack
Importance of Each Tool
- Electric mixer: This tool saves time and ensures that your butter and sugar are creamed to perfection for a light, fluffy texture.
- Mixing bowls: Using separate bowls for dry and wet ingredients helps prevent overmixing and ensures thorough incorporation of flavors.
- Cooling rack: Allows air circulation around your cake, helping it cool evenly without getting soggy on the bottom.

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 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 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 the all-purpose flour, baking powder, and salt.
- In a measuring cup, combine whole milk, fresh key lime juice, zest, and vanilla extract.
- Gradually add the 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.
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 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. Then add key lime juice, zest, and salt; beat until fluffy and spreadable. Adjust consistency by adding more juice for tanginess or more sugar for thickness if necessary.
Step 5: Assemble the Cake
Place one layer of cooled cake on a serving plate. Spread frosting generously on top before adding the second layer. Frost both the top and sides of the cake as desired. Garnish with additional lime zest, lime slices, or crushed graham crackers for that classic key lime pie feel!
