Preparing Key Lime Pound Cake
Creating a delectable key lime pound cake in your own kitchen is a delightful experience that will leave your friends and family raving about your baking prowess. Follow these simple steps to ensure your cake turns out perfectly every time!
Gather Your Ingredients
Before diving into the mixing and baking, gather all your ingredients. For this recipe, you will need:
- 3 cups white sugar
- 1 cup unsalted butter, softened
- ½ cup shortening
- 3 cups cake flour, sifted
- ½ teaspoon baking powder
- ⅛ teaspoon salt
- 6 large eggs
- 1 cup heavy cream
- ¼ cup fresh Key lime juice
- 1 teaspoon lime zest
- 1 teaspoon vanilla extract
- 1 cup powdered sugar
- 2 tablespoons Key lime juice
- ½ teaspoon vanilla extract
Having everything in one place not only saves time but also helps you avoid any last-minute scrambles!
Cream Together Sugar, Butter, and Shortening
In a large mixing bowl, combine the white sugar, softened butter, and shortening. Using a hand mixer or stand mixer, cream these ingredients together until the mixture is light and fluffy. This step is crucial because it incorporates air into the fat, which will help your key lime pound cake rise beautifully.

Mix in the Eggs and Heavy Cream
Once your mixture is fluffy, add the eggs one at a time, ensuring each is well incorporated before adding the next. After all the eggs are mixed in, pour in the heavy cream, fresh Key lime juice, lime zest, and vanilla extract. Mix until the wet ingredients are completely combined. The combination of Key lime juice and zest adds a zesty tang that truly shines in this cake!
Combine Dry Ingredients with the Wet Mixture
In a separate bowl, whisk together the cake flour, baking powder, and salt. This ensures that the leavening agent is evenly distributed. Gradually fold the dry mixture into your wet ingredients until just combined; be careful not to overmix, as this could lead to a denser pound cake.
Bake Your Pound Cake to Perfection
Preheat your oven to 350°F (175°C) and prepare your pans—grease and flour a bundt pan or two loaf pans to prevent sticking. Pour your fabulously smooth batter into the prepared pans. Bake for approximately 55 to 65 minutes, or until a toothpick inserted into the center comes out clean. Once done, allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack. The delightful aroma of key lime pound cake baking will fill your home, setting the stage for a remarkable dessert.
With these steps, you’ll create a luscious key lime pound cake that’s perfect for any occasion. Enjoy every bite!
