Step‑by‑Step Instructions for Key Lime Pound Cake
Step 1: Preheat and Prepare the Bundt Pan
Begin by preheating your oven to 325°F (165°C). While the oven warms up, generously grease a bundt pan with unsalted butter to ensure easy release later. Make sure every crevice is covered, and you can dust it lightly with flour for added protection. This will give your Key Lime Pound Cake a beautiful, textured finish.
Step 2: Whisk Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and ½ teaspoon of fine sea salt. Then, add the zest of 2 limes to this mixture, ensuring it’s evenly distributed. This step infuses your Key Lime Pound Cake with wonderful citrus flavor, enhancing the overall taste profile. Set this bowl aside for later use.
Step 3: Cream Butter and Sugar
In another bowl, combine 1 cup of softened unsalted butter and 2 cups of granulated sugar. Using an electric mixer, cream these together on medium speed until the mixture turns light and fluffy, approximately 3-5 minutes. This process adds air to the batter, contributing to the cake’s tender crumb. Remember to scrape down the sides of the bowl to incorporate all ingredients well.
Step 4: Add Wet Ingredients
Now, mix in the juice of 3 fresh limes, ½ cup of sour cream, and ½ cup of buttermilk to your creamed mixture. Blend until fully combined, ensuring there are no lumps. The addition of these wet ingredients will enhance the moisture of the Key Lime Pound Cake. This luscious mixture should have a smooth consistency before moving to the next step.
Step 5: Incorporate Eggs
Add 4 large room temperature eggs one at a time, beating well after each addition. This step is vital for emulsifying your batter, which creates a cohesive mixture. You should see the batter becoming richer and thicker with each egg added—this is exactly what you want for your Key Lime Pound Cake!
Step 6: Combine Dry and Wet Mixtures
Gradually pour the dry ingredient mixture into the wet ingredients, mixing gently until just combined. Be careful not to overmix, as this can result in a denser cake. The batter should be thick yet smooth, showcasing a beautifully combined texture. Once everything is amalgamated, you’re ready for the next step.
Step 7: Transfer to Bundt Pan
Pour the batter into the prepared bundt pan, using a spatula to level the top evenly. Gently tap the pan on the countertop to remove any air bubbles trapped within. This ensures your Key Lime Pound Cake bakes beautifully without any unsightly holes, giving it a polished look when served.
Step 8: Bake the Cake
Place the bundt pan in the preheated oven and bake for 75-80 minutes. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs attached. Enjoy the delightful aroma of citrus wafting through your kitchen as the cake bakes to golden perfection.
Step 9: Cool in the Pan
Once baked, remove the Key Lime Pound Cake from the oven and let it cool in the pan for 10-15 minutes. This resting period allows the cake to firm up and makes it easier to invert onto a cooling rack. After it’s slightly cooled, carefully run a knife around the edges to ensure it releases smoothly.
Step 10: Prepare the Glaze
While the cake cools, prepare the glaze by mixing 1 cup of powdered sugar with 2-3 tablespoons of lime juice in a small bowl. Stir until it reaches a smooth, pourable consistency. Adjust the amount of lime juice for your desired thickness; the glaze should coat the back of a spoon without being too runny.
Step 11: Glaze the Cake
Once the cake has completely cooled, place it on a serving plate. Pour the smooth glaze over the top, allowing it to drip down the sides for a beautiful effect. If you’ve placed the cake on wax paper, it helps catch any drips, making cleanup a breeze and giving your Key Lime Pound Cake that extra special touch.

Expert Tips for Key Lime Pound Cake
• Room Temperature Essentials: Using room temperature ingredients, especially butter and eggs, allows for better emulsification and a lighter texture in your Key Lime Pound Cake.
• Avoid Overmixing: Once you add the eggs, mix just until combined to prevent a dense cake. Overmixing can lead to an undesirable texture.
• Bundt Pan Prep: Properly grease and flour your bundt pan to ensure a flawless release. A homemade pan release can also be a great alternative for easy removal.
• Cooling Time Matters: Let the cake cool for a short while in the pan before inverting. Doing so helps with structure but don’t leave it too long or it may stick!
• Glaze Consistency: Aim for a glaze that coats a spoon but isn’t overly thick. Adjust lime juice to find the right balance for your Key Lime Pound Cake glaze.
Make Ahead Options
These Key Lime Pound Cakes are a fantastic option for busy home cooks looking to save time! You can prepare the cake batter up to 24 hours in advance by mixing everything together and then storing it in an airtight container in the fridge.

If you prefer, you can also bake the cake and let it cool completely, then wrap it tightly in plastic wrap and refrigerate for up to 3 days or freeze for up to 3 months. When you’re ready to enjoy, simply glaze the cake after thawing to retain its moist texture, ensuring every slice is just as delicious as the day you made it!

Key Lime Pound Cake Recipe FAQs
How do I choose the best limes for my Key Lime Pound Cake?
Absolutely! When selecting limes, look for ones that are firm and heavy for their size, indicating they are juicy. The skin should be smooth and vibrant without dark spots or blemishes. If you gently squeeze the lime, it should yield slightly to pressure, which means it’s ripe and ready to juice.
How should I store my Key Lime Pound Cake?
To keep your cake fresh, store it in an airtight container at room temperature for about 4-5 days. If you’re planning on enjoying it later, slice the cake and wrap each piece tightly in plastic wrap before placing them in an airtight freezer bag. This way, your delicious Key Lime Pound Cake can be frozen for up to 3 months, maintaining its delightful moisture and flavor. Just make sure to label the bag with the date!
Can I freeze my Key Lime Pound Cake?
Yes, indeed! To freeze your Key Lime Pound Cake, first let it cool completely. Then, slice the cake into your desired sections. Wrap each slice individually in plastic wrap, ensuring there’s no exposure to air. Place the wrapped slices in a freezer-safe bag or container. For best results, enjoy them within 3 months to experience the best flavor and texture when thawed. To defrost, simply place the slices in the refrigerator overnight or warm them in the microwave for a few seconds.
What can I do if my Key Lime Pound Cake is too dense?
If your cake comes out denser than you’d like, there are a few potential reasons. Firstly, it’s essential not to overmix the batter after adding the eggs, as this can develop too much gluten and lead to density. Additionally, ensure that your measurements are accurate, especially with flour—using too much can also yield a heavier cake. If it’s already baked and you’re seeking an improvement, try serving it with whipped cream or a dollop of yogurt to balance out the texture!
Are there any dietary considerations I should keep in mind?
Very much so! This recipe contains eggs and dairy, which are common allergens. For those with egg allergies, you can substitute each egg with a flaxseed meal mix (1 tablespoon of flaxseed meal + 2.5 tablespoons water, let it sit for 5 minutes). If you’re looking for a dairy-free version, consider using a non-dairy yogurt and milk substitute. Always double-check labels on commercial products if allergies are a concern!
Can I use other flavors instead of lime?
The more the merrier! You can easily swap the lime ingredients with lemon to create a refreshing Lemon Pound Cake or incorporate shredded coconut to make a Coconut Key Lime variation. Just remember, adjusting the flavors might require tweaking the amounts to maintain the right balance in your cake!
