Ingredients Needed for Key Lime Cake Recipe
To achieve the ideal taste and texture, you’ll need some essential ingredients. Using quality items is crucial because they help create a cake that is not only delicious but also stands out with its vibrant flavor.
Basic Ingredients:
- 2 cups all-purpose flour
- 1 1/2 cups granulated sugar
- 1/2 teaspoon salt

- 1/2 cup vegetable oil
- 4 large eggs

Choosing the Right Key Limes
The difference between key limes and regular limes goes beyond just their size. Key limes have thinner skin and a more distinct tartness, making them ideal for use in desserts. When used in a cake, key limes provide a balanced flavor that combines both tart and sweet.
Tips for Selecting and Using Key Limes:
- When purchasing key limes, select bright green ones that feel heavy for their size.
- To get the most juice, roll the limes on the countertop with gentle pressure before cutting.
- If fresh key limes are unavailable, bottled key lime juice can be used. However, it’s important to choose a high-quality product without added sugars.
For another dessert featuring citrus flavors, consider trying a lemon cookie recipe. It’s perfect for those who enjoy a mix of tart and sweet in their treats.
Making the Key Lime Cake Batter
The batter is the foundation of your cake. Therefore, following these steps carefully will help you achieve a moist and fluffy texture:
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- Mix the dry ingredients: In a large bowl, whisk together the flour, sugar, salt, baking powder, and baking soda.
- Combine the wet ingredients: In a separate bowl, beat the eggs, then add the oil, buttermilk, key lime juice, zest, and vanilla extract. Combine everything until the ingredients are completely integrated.
- Gradually add the wet mixture to the dry ingredients, stirring just until combined to avoid overmixing.
- Add food coloring (optional): If you want a more pronounced green hue, add a few drops of food coloring.
Incorporating buttermilk and oil helps to keep the cake moist. Moreover, if you want a bit more structure, adding a small amount of gelatin can help. For another recipe that features a rich, flavorful cake, try this easy pineapple cake.
Baking Instructions
Baking the cake properly is essential to achieving the perfect texture. Therefore, follow these steps to ensure even baking:
- Evenly divide the batter between the prepared cake pans and pour it in.
- Bake for 25-30 minutes, or until a toothpick inserted into the center emerges clean.
- Turn the pans halfway through the baking time to promote even cooking.
- Let the cakes cool in the pans for 10 minutes before moving them to a wire rack to cool fully.
It’s essential to let the cakes cool completely before frosting, as this prevents the frosting from melting.
Preparing Key Lime Frosting or Glaze
The frosting or glaze is an important component of this cake, as it enhances the citrusy flavors. A cream cheese lime frosting pairs perfectly with the key lime cake.
Cream Cheese Lime Frosting Ingredients:
- 8 oz cream cheese, softened
- 1/2 cup unsalted butter, softened
- 4 cups powdered sugar
- 2 tablespoons key lime juice
- 1 tablespoon key lime zest
- 1 teaspoon vanilla extract
Instructions for Making the Frosting:
- Whip the cream cheese and butter together until they reach a smooth consistency.
- Slowly incorporate the powdered sugar, blending until the frosting becomes airy and fluffy.
- Add the key lime juice, zest, and vanilla extract, then beat until fully incorporated.
Alternatively, you can make a simple lime glaze by mixing key lime juice with powdered sugar. It’s a lighter option that still adds a delicious tart finish. This is especially suitable if you prefer a less rich topping.
Assembling the Cake
Now that the cake layers and frosting are prepared, it’s time to assemble your key lime cake:
- Place one cake layer on a serving plate. Apply a thick layer of frosting over the top.
- Add the second layer, and frost the top and sides, using a spatula to smooth it out.
- Decorate as desired. You could add lime slices, zest, or shredded coconut for a decorative touch.

These decoration options not only make the cake look stunning but also add layers of flavor and texture.
Storing and Serving Suggestions
Proper storage ensures your key lime cake recipe stays fresh. To keep it at its best, follow these tips:

- Wrap it tightly with plastic wrap and store in an airtight container to prevent it from drying out.
- Let the cake sit at room temperature for 20 minutes before serving to soften the frosting slightly.
If you’re making the cake ahead of time, freezing the unfrosted layers and frosting them later is a good option, as it will help maintain freshness.
