How to Make Key Lime Pound Cake
-
Preheat oven to 350°F (175°C). While your oven is heating, prepare a 10-inch bundt pan or two 9-inch loaf pans by greasing and flouring them to ensure your cake releases easily once baked.
-
Cream together white sugar, unsalted butter, and shortening in a large bowl using an electric mixer until the mixture is light and fluffy, which should take about 3-5 minutes.
-
Add eggs one at a time, beating well after each addition. Next, mix in the heavy cream, Key lime juice, lime zest, and vanilla extract until everything is well combined and uniform in texture.
-
In a separate bowl, whisk together the cake flour, baking powder, and salt until thoroughly mixed. This step is crucial for an even rise in your cake.
-
Gradually fold the dry ingredients into the wet mixture using a spatula until just combined. Be gentle; overmixing can lead to a dense cake.
-
Pour the batter into the prepared pans, smoothing the top lightly with a spatula, which will help it bake evenly. Bake for 55-65 minutes, or until a toothpick inserted in the center comes out clean.
-
Cool the cake in the pan for 10 minutes before transferring it to a wire rack. This helps maintain its structure as it cools completely.
-
Prepare glaze by whisking powdered sugar, Key lime juice, and vanilla extract until smooth and creamy. This will provide a delightful sweet finish to your cake.
-
Drizzle glaze over the completely cooled cake, allowing it to set before slicing and serving, which enhances both flavor and presentation.
Optional: Serve with a dollop of whipped cream or fresh lime slices for an extra touch.

Expert Tips for Key Lime Pound Cake
-
Room Temperature Ingredients: Ensure all your ingredients, especially the butter and eggs, are at room temperature. This helps them blend seamlessly for a fluffy batter.
-
Gentle Mixing: When combining the wet and dry ingredients, fold gently. Overmixing can lead to a dense cake, which is something we want to avoid with this light Key Lime Pound Cake!
-
Check Freshness: Ensure your baking powder is fresh for optimal rising. A simple test: add a teaspoon to hot water; if it bubbles vigorously, it’s good to use.
-
Cooling Time: Allow the cake to cool completely before drizzling the glaze. This prevents the glaze from melting and ensures a beautiful finish.
-
Zest with Care: Use a microplane for fine lime zest, avoiding the bitter white pith underneath. A little zest goes a long way for that vibrant lime flavor!
Key Lime Pound Cake Recipe FAQs
What kind of Key limes should I use for the cake?
Absolutely! For the best flavor, use fresh, bright green Key limes. Look for those that feel heavy for their size and have a smooth skin without any dark spots. If fresh Key limes aren’t available, bottled Key lime juice is a suitable substitute, though it may lack some of the vibrant flavor.
How should I store my Key Lime Pound Cake?
To keep your cake fresh and moist, store it wrapped in plastic wrap or in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate it for up to a week. Just be sure to wrap it well to prevent it from drying out.

Can I freeze leftover Key Lime Pound Cake?
Very! Freezing is a great option for this cake. Wrap it tightly in plastic wrap and then in aluminum foil or a freezer-safe bag. It can be frozen for up to 3 months. When you’re ready to enjoy it, simply thaw it in the fridge overnight or at room temperature for a few hours. For a warm treat, microwave slices for about 15-20 seconds!
What if my Key Lime Pound Cake is too dense?
If your cake turns out dense, it could be due to overmixing after adding the flour. Next time, fold the ingredients together gently until just combined. Also, ensure that your baking powder is fresh; it should bubble vigorously when tested. Lastly, make sure you’re using room temperature ingredients to incorporate air better.
Can I make this cake dairy-free or gluten-free?
Absolutely! To make a dairy-free version, substitute unsalted butter and heavy cream with vegan butter and full-fat coconut milk, respectively. For a gluten-free option, swap the cake flour with a gluten-free blend designed for baking, ensuring it has a binding agent like xanthan gum.
Is it safe for pets or those with allergies?
It’s important to note that while Key Lime Pound Cake is a delightful treat for humans, it contains ingredients like sugar and butter that shouldn’t be given to pets. Additionally, for those with allergies, always double-check the ingredients for potential allergens such as eggs, gluten, or dairy before serving.
