Step 2: Mix the Dry Ingredients
In a medium bowl, sift together your flour, baking powder, and salt. This step is more than just tradition; sifting helps aerate the flour and removes any lumps, creating a light and fluffy cake. Set this aside and focus on the wet ingredients!
Step 3: Cream the Butter and Sugar
Now, grab your large bowl or stand mixer. Cream together the sugar and softened butter until the mixture turns light and fluffy. This typically takes about 3-5 minutes. Afterward, mix in the lime juice and zest, followed by the eggs, one at a time. The key here is to beat the mixture on high speed to get some air into it; this will contribute to the cake's moist texture.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to your butter and sugar mixture. Alternate with adding the milk, stirring on low speed until you have a smooth batter. It’s like blending the best of both worlds—sweet and tangy!
Step 5: Bake to Perfection
Preheat your oven to 350°F. Divide the batter evenly into the prepared loaf pans and bake for about 55 to 60 minutes. Pro tip: You’ll know the cake is done when a toothpick inserted into the center comes out clean. Let the cakes cool for about 20 minutes before transferring them to a wire rack to cool completely, which takes about 2 hours.
Step 6: Glaze the Cooled Cakes
After your cakes have cooled, it’s time to whip up that zesty glaze! Whisk together the powdered sugar, milk, and lime zest until smooth. If it’s too thick, add milk a little at a time until you reach a drizzle-able consistency. Once ready, place your cake on a wire rack and allow the glaze to drape luxuriously over the tops.
And voilà! Your key lime pound cake is ready to be enjoyed. The combination of sweet and tart is sure to brighten anyone’s day. Be sure to share your thoughts in the comments after you give this recipe a try!

Baking Notes for Key Lime Pound Cake
Common pitfalls to avoid
When baking your key lime pound cake, ensure the butter is softened but not melted—this helps achieve that light and fluffy texture. Additionally, avoid overmixing after adding the flour; this can lead to a dense cake. Also, make sure to test the cake with a toothpick toward the end of the baking time; it should come out clean. If the toothpick has wet batter on it, give the cake a few more minutes in the oven.
Adjusting for altitude and humidity
Baking at high altitudes? You may need to reduce sugar by a little and increase the flour slightly to maintain structure. In humid environments, you might discover the cake batter seems too wet. Adding a touch more flour can help balance the moisture. Always remember that baking is a science, so these small adjustments can save your key lime pound cake from potential disaster!

Tips for Making Perfect Key Lime Pound Cake
Fresh Ingredients Matter
Using fresh ingredients is crucial for a delightful key lime pound cake. Opt for real key limes rather than bottled juice to get that vibrant citrus flavor. Freshly grated lime zest can also elevate your cake, adding a fragrant aroma that’s impossible to resist. When possible, include organic eggs and dairy for the best texture and taste.
The Importance of Room Temperature Items
Ensure your butter, eggs, and milk are at room temperature before you start baking. This helps achieve a uniform batter, resulting in a smoother, denser cake that bakes evenly. Room temperature ingredients blend together better, creating an airy and fluffy texture that’s essential for a perfect key lime pound cake.
