Ingredients
To create this delicious Key Lime Pound Cake, you’ll need the following ingredients:
For the Cake Base
- 1 cup butter, softened
- 2 cups sugar
- 4 large eggs
- 3 cups all-purpose flour
- 1/2 tsp baking soda
- 1 cup buttermilk
- 1/4 cup lime juice
- 1 tsp lime zest
How to Make Key Lime Pound Cake Recipe
Step 1: Preheat the Oven
Preheat your oven to 325°F (165°C). Grease and flour a 10-inch tube pan to ensure easy removal after baking.
Step 2: Cream Butter and Sugar
In a large bowl, cream together the butter and sugar until light and fluffy. This process incorporates air into the mixture, leading to a lighter cake texture.
Step 3: Add Eggs
Beat in the eggs, one at a time. Mix well after each addition to ensure they are fully incorporated into the batter.
Step 4: Combine Dry Ingredients
In another bowl, combine the flour and baking soda. Gradually add this mixture alternately with the buttermilk to the creamed mixture. Start and end with flour.
Step 5: Add Lime Flavoring
Stir in the lime juice and lime zest. This step infuses your batter with that refreshing key lime flavor.
Step 6: Pour Batter Into Pan
Pour the batter into your prepared tube pan evenly. Gently spread it out using a rubber spatula if needed.
Step 7: Bake Your Cake
Bake in your preheated oven for about 60–70 minutes. Check doneness by inserting a toothpick into the center; it should come out clean when done.
Step 8: Cool Before Serving
Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack. Let it cool completely before slicing into delightful pieces.
How to Serve Key Lime Pound Cake Recipe

With Whipped Cream

Fresh Berries
- Serve with a mix of fresh berries like strawberries, blueberries, or raspberries. Their sweetness pairs beautifully with the tartness of the cake.
Lime Glaze

How to Perfect Key Lime Pound Cake Recipe
Creating the perfect Key Lime Pound Cake requires attention to detail. Here are some tips to ensure your cake turns out delicious every time.
-
Use Room Temperature Ingredients: Bring butter, eggs, and buttermilk to room temperature before mixing. This helps create a smooth batter for even baking.
-
Don’t Overmix: Mix just until ingredients are combined. Overmixing can lead to a dense cake rather than a light and fluffy texture.
-
Measure Flour Correctly: Use the spoon-and-level method for measuring flour. Too much flour can make the cake dry, while too little can affect its structure.
-
Check Oven Temperature: Use an oven thermometer to ensure your oven is at the correct temperature. An inaccurate oven can lead to uneven baking.
-
Cool Gradually: Let the cake cool in its pan for 10 minutes before transferring it to a wire rack. This helps prevent breaking and ensures it retains moisture.

Common Mistakes to Avoid
To ensure your Key Lime Pound Cake turns out perfectly, avoid these common mistakes.
- Skipping the room temperature ingredients: Using cold butter or eggs can prevent the batter from emulsifying properly. Always let them sit at room temperature before mixing.
- Not measuring flour correctly: Over-measuring flour can lead to a dense cake. Use the spoon-and-level method for accurate measurement.
- Ignoring the baking time: Ovens can vary in temperature. Check your cake a few minutes before the recommended time to avoid overbaking.
- Forgetting to grease the pan: A well-greased pan is essential for easy removal. Be sure to grease and flour your tube pan thoroughly.
- Adding too much lime juice: While flavor is important, too much lime juice can affect the batter’s consistency. Stick to the recipe measurements for best results.
