How to Make Key Lime Pound Cake
-
Preheat oven: Start by heating your oven to 350°F. Grease and lightly flour two 9×5-inch loaf pans to ensure easy removal after baking.
-
Prepare dry ingredients: In a medium bowl, sift or whisk together the flour, baking powder, and salt. This helps to aerate the flour for a fluffy cake. Set aside.
-
Cream butter and sugar: In a large bowl or stand mixer with a paddle attachment, cream the softened butter and sugar together until light and fluffy. Add in the lime juice, lime zest, and eggs, beating on high speed for 2-3 minutes until well combined.
-
Mix dry and wet ingredients: Carefully add the flour mixture alternately with the milk to the sugar mixture on low speed. Beat just until the batter is smooth, taking care not to overmix.
-
Pour batter: Evenly distribute the batter into the prepared loaf pans. Give them a gentle tap on the counter to remove any air bubbles.
-
Bake cakes: Place the pans on the middle rack of the oven and bake for 55 to 60 minutes, or until a toothpick inserted into the center comes out clean. Cool for 20 minutes in the pans, then remove to a wire rack to cool completely, about 2 hours.
-
Make the glaze: Once cooled, whisk together the powdered sugar, milk, and lime zest in a bowl. Add more milk gradually until you reach a drizzle-able consistency without making it too runny.
-
Glaze the cake: Set the cake on a cooling rack with aluminum foil or parchment underneath. Spoon the glaze generously over the cakes, allowing any excess to drip below. Let the glaze set before transferring it to a serving tray.
Optional: Serve with a dollop of whipped cream for an extra touch!

Expert Tips for Key Lime Pound Cake
• Fresh is Best: Use fresh limes for juice and zest to maximize flavor. Bottled lime juice doesn’t have the same vibrant taste.
• Room Temperature Ingredients: Ensure butter, eggs, and milk are at room temperature for a smoother batter and even baking.
• Avoid Overmixing: Mix delicately, especially after adding the flour. Overmixing can result in a dense cake instead of a light, airy Key Lime Pound Cake.
• Test for Doneness: Always test with a toothpick; if it comes out clean, your cake is ready. If it comes out with wet batter, give it a few more minutes.
• Cool Completely: Allow the cake to cool completely before glazing; otherwise, it may cause the glaze to melt and run off instead of sitting beautifully on top.
Make Ahead Options
These Key Lime Pound Cakes are perfect for meal prep enthusiasts! You can make the batter a day in advance and store it in the refrigerator to save time. Simply combine the dry ingredients and the wet ingredients, but hold off on the lime glaze until right before serving to maintain that gorgeous finish. If you prefer, you can bake the cakes up to 3 days ahead of your event; just ensure they are completely cooled and wrapped tightly in plastic wrap to keep them moist and delicious. When ready to enjoy, simply make the glaze and drizzle it over the cooled cakes for a fresh, zesty touch that will leave your taste buds singing!
Key Lime Pound Cake Recipe FAQs
How do I select the best limes for my Key Lime Pound Cake?
Absolutely! Choose limes that are firm, slightly heavy, and have smooth skin. Avoid limes with dark spots or blemishes, as these can indicate overripeness. Fresh limes will yield more juice and zest, giving your cake that wonderful zesty flavor.
How should I store my Key Lime Pound Cake?
To keep your Key Lime Pound Cake fresh, store it in an airtight container at room temperature for up to 3 days. If you’d like to keep it longer, it’s best placed in the fridge where it can last for about a week, retaining its delicious lime flavor and moist texture.
Can I freeze Key Lime Pound Cake, and how do I do it?
Very! To freeze your Key Lime Pound Cake, wrap it tightly in plastic wrap followed by aluminum foil. This will protect it from freezer burn. You can freeze it for up to 3 months. When you’re ready to enjoy a slice, transfer it to the fridge to thaw overnight, or let it sit at room temperature for a couple of hours.
What can I do if my cake doesn’t rise properly?
If your Key Lime Pound Cake doesn’t rise as expected, check a couple of things: ensure that your baking powder is fresh—not expired—since that’s key for a good rise. Also, make sure you’re not overmixing the batter; mixing just until ingredients are combined is crucial for a light, airy texture.
Are there any dietary considerations for Key Lime Pound Cake?
Definitely! If you have guests with allergies, keep in mind that this recipe contains gluten and dairy. For a gluten-free alternative, consider using a gluten-free flour blend. Additionally, you can substitute the butter with a plant-based margarine for a dairy-free option. This cake is also not suitable for pets, especially dogs, due to the sugar content.
How can I adjust the glaze for my Key Lime Pound Cake?
If you prefer a thicker glaze, add less milk to the powdered sugar initially until your desired consistency is reached. Conversely, for a thinner glaze, add the milk gradually until you achieve a drizzle-able state. As a tip, you can boost the lime flavor in your glaze with extra lime zest for that delightful zesty kick!
