Step‑by‑Step Instructions for Key Lime Pound Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, prepare your bundt pan or loaf pans by greasing them thoroughly with butter or cooking spray, then dusting with flour to ensure an easy release of your delicious Key Lime Pound Cake later.
Step 2: Cream Together the Mixture
In a large mixing bowl, combine the white sugar, unsalted butter, and shortening. Using an electric mixer, beat the mixture on medium speed until it becomes light and fluffy, usually around 3-5 minutes. This creaming process is key for a tender, airy cake texture, so keep an eye on the consistency—smooth and pale is what you’re aiming for!
Step 3: Incorporate the Eggs
Add the large eggs one at a time into the creamed mixture, mixing well after each addition. You want to ensure that each egg is fully incorporated before adding the next; this will help to trap air and contribute to the lightness of your Key Lime Pound Cake.
Step 4: Mix in Wet Ingredients
Next, pour in the heavy cream, freshly squeezed Key lime juice, lime zest, and vanilla extract. Mix gently until everything is just combined. The mixture will have a lovely, fragrant aroma at this stage, and you can see the vibrant zest peeking through—this is a sign of the zesty flavors to come!
Step 5: Combine the Dry Ingredients
In a separate bowl, whisk together the cake flour, baking powder, and salt. Gradually add this dry mixture to your wet ingredients, folding gently until just combined. Be careful not to overmix, as this can lead to a dense cake; you want the batter to remain slightly lumpy for a tender crumb in your Key Lime Pound Cake.
Step 6: Pour and Bake
Carefully pour the batter into your prepared pan, smoothing the top with a spatula. Place it in the preheated oven and bake for 55 to 65 minutes, or until a toothpick inserted into the center comes out clean. Keep an eye on the cake during the last few minutes to prevent over-baking, which can dry it out.
Step 7: Cool the Cake
Once baked, remove the pan from the oven and let it cool in the pan for about 10 minutes. This will help the Key Lime Pound Cake set and makes it easier to transfer without breaking. After cooling, gently turn it out onto a wire rack to cool completely, which allows air to circulate and prevents sogginess.
Step 8: Prepare the Glaze
While the cake is cooling, prepare the glaze by mixing powdered sugar, Key lime juice, and vanilla extract in a small bowl. Stir until you achieve a smooth consistency that can be drizzled. This glaze will add a glossy finish and zesty kick to your Key Lime Pound Cake—perfect for enhancing its refreshing flavors!
Step 9: Glaze and Serve
Once the cake has completely cooled, drizzle the glaze generously over the top, allowing it to drip down the sides. Let the glaze set for a few moments before slicing. Your Key Lime Pound Cake is now ready to be enjoyed—slice up and share with family or friends for a delightful treat!
What to Serve with Refreshing Key Lime Pound Cake?
Imagine the warm, inviting aroma of freshly baked cake mingling with bright flavors, creating the perfect centerpiece for your dessert table.

- Fresh Berries: Strawberries, blueberries, or raspberries offer a burst of sweetness and acidity, creating a delightful contrast that complements the tangy Key lime cake beautifully.
- Coconut Flakes: Toasted coconut adds a tropical flair and chewy texture, enhancing the cake’s vibrant flavors while infusing it with an island-inspired charm.
- Citrus Sorbet: A scoop of lemon or lime sorbet provides a refreshing palate cleanser, heightening the cake’s citrus profile and keeping the mood bright and summery.
- Mint Tea or Lemonade: A chilled glass of mint tea or lemonade pairs perfectly with the cake, offering refreshing sips that balance the sweetness while adding their own layer of bright flavor.

Key Lime Pound Cake Recipe FAQs
What’s the best way to choose Key limes for this cake?
Absolutely! When selecting Key limes, look for ones that are firm and smooth, with a vibrant green color. Avoid any that have dark spots or feel overly soft, as these may be past their prime. For the best flavor, I recommend using fresh Key limes, as they have a more intense taste than bottled juice.
How should I store leftover 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 want it to last longer, wrap it tightly in plastic wrap and refrigerate it, where it will stay tasty for about a week.
Can I freeze Key Lime Pound Cake for later use?
Yes, you can freeze your Key Lime Pound Cake! I often slice it and wrap each piece individually in plastic wrap, then place them in a freezer-safe bag or container. It will stay good for up to 3 months. When ready to enjoy, simply thaw in the fridge overnight, and for an extra treat, warm the slice slightly in the microwave before serving!
What do I do if my cake is dry or dense?
If your Key Lime Pound Cake turns out dry, it might have been overbaked or overmixed. Ensure you’re using the toothpick test—it should come out clean but moist. If you’re mixing, do so just until the ingredients are combined. Remember, a gentle touch is key! Lastly, adding a drizzle of glaze can help moisten each slice before serving.
Is this cake suitable for people with allergies?
Very! While this Key Lime Pound Cake contains eggs and dairy, you can make it more allergy-friendly. Substitute the eggs with a flaxseed mixture (1 tablespoon flaxseed meal + 2.5 tablespoons water = 1 egg), and use dairy-free butter and heavy cream. Always check the labels of your ingredients, especially for any hidden allergens!
