Step‑by‑Step Instructions for Key Lime Pound Cake
Step 1: Preheat and Prepare Pans
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take two small loaf pans and generously coat them with non-stick baking spray to ensure easy removal of the cake later. Set these pans aside as the baking space fills with the anticipation of a delicious Key Lime Pound Cake.
Step 2: Mix Dry and Wet Ingredients
In a large mixing bowl, combine the vanilla pound cake mix, cold water, melted butter, large egg, fresh key lime juice, key lime zest, and lime gel food coloring if using. Stir the ingredients together until well mixed and smooth, ensuring you incorporate every bit of flour. The batter should be thick but pourable in texture, ready to transform into a scrumptious cake!
Step 3: Divide and Tap
Once your batter is perfectly blended, evenly divide it between the two prepared loaf pans. For a uniform texture, gently tap the pans against your kitchen counter to release any trapped air bubbles hiding in the batter. This helps ensure that your Key Lime Pound Cake bakes evenly, resulting in a delightful finished product.
Step 4: Bake the Cakes
Place the filled loaf pans into the preheated oven and bake for 30-35 minutes. Keep an eye on them, as you’ll know they are done when a toothpick inserted into the center comes out clean, with only a few moist crumbs attached. This visual cue is crucial for determining doneness, so be sure not to skip this step!
Step 5: Cool the Cakes
Once baked to perfection, remove the pans from the oven and let them cool for about 10 minutes on a wire rack. This cooling period prevents the cakes from breaking apart as you carefully release them from the pans. Your house will start to smell divine as the Key Lime Pound Cake cools, inviting everyone to gather around the kitchen.
Step 6: Prepare the Zesty Glaze
While the cakes cool, it’s time to whip up the zesty glaze. In a medium bowl, whisk together the powdered sugar, key lime juice, and additional key lime zest until smooth and free of lumps. The glaze should be thick yet pourable, ready to drizzle over your cooled cakes to add that luscious finish we all love.
Step 7: Drizzle and Serve
Once your Key Lime Pound Cakes have fully cooled, drizzle the prepared glaze generously over the tops. Allow it to set for a few minutes, as this final touch not only enhances the flavor but adds an eye-catching gloss to the moist cake. Slice them up and prepare to bask in the delight your creation will bring!

Expert Tips for Key Lime Pound Cake
- Melted Butter: Ensure the butter is completely melted before mixing to prevent lumps in your batter for a smooth Kay Lime Pound Cake.
- Avoid Overmixing: Mix just until combined to maintain the cake’s tender crumb and avoid a rubbery texture.
- Cooling Time: Let the cakes cool in the pans for about 10 minutes before transferring to wire racks to prevent breaking.
- Taste Adjustment: After mixing, taste the batter for lime intensity and adjust fresh key lime juice if needed for that perfect zesty flavor.
- Uniform Baking: Tap the pans gently on the counter to release air bubbles, ensuring even baking and a beautiful rise on your Key Lime Pound Cake.

Room Temperature: Store your Key Lime Pound Cake in an airtight container at room temperature for up to 3-4 days to maintain its moist and delicious texture.

Key Lime Pound Cake Recipe FAQs
How do I select ripe key limes?
Absolutely! When selecting key limes, look for limes that are firm and have a nice, smooth skin. They should feel heavy for their size, indicating juiciness. Avoid limes that have dark spots or are overly soft, as these may be past their prime.
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 3-4 days. If you prefer to prolong its life, wrap the cake tightly in plastic wrap and store it in the refrigerator. Just be sure to let it come to room temperature before serving to enhance its flavors.
Can I freeze the Key Lime Pound Cake?
Yes, you can! Wrap the cooled cake tightly in plastic wrap and then place it in a freezer-safe bag or container. It will keep well for up to 2 months. When you’re ready to enjoy it again, let it thaw overnight in the refrigerator. For an extra treat, microwave a slice for 10-15 seconds to revive its delightful moistness!
What if my cake sinks in the middle?
Very common! A sinking cake can often be due to a few factors: overmixing the batter, an oven temperature that is too low, or not baking the cake long enough. Ensure you follow the mixing instructions carefully and use an oven thermometer to confirm the correct baking temperature. If you notice the cake is still underbaking, leave it in for an extra 5 minutes, and perform the toothpick test again.
Is this recipe safe for those with allergies?
Certainly! This Key Lime Pound Cake contains common allergens like egg and wheat. If you or your guests have specific allergies, consider using egg substitutes or gluten-free cake mixes. For those with citric allergies, opt for lemon juice instead of key lime, though the taste will be slightly different. Always check labels for your toppings and additional garnishes!
Can pets eat key lime cake?
No, it’s best to keep this cake away from pets. The key lime juice and glaze may contain sugar and other ingredients that can be harmful to animals. Always consult with your veterinarian about safe treats if you’re looking to share with your furry friends!
