How to Make Key Lime Pound Cake
Step 1: Preheat Your Oven
Heat the oven to 350°F. Greasing and lightly flouring two 9×5-inch loaf pans will ensure that your cakes slide right out once they’re baked. This step is crucial because no one likes to see their hard work stick to the pan!
Step 2: Prepare Dry Ingredients
In a medium bowl, sift or whisk together the flour, baking powder, and salt. This process helps aerate the flour and ensures even mixing later on. Set this mixture aside while we tackle the wet ingredients.
Step 3: Cream Sugar and Butter
In a large bowl (or using a stand mixer), cream together the sugar and softened butter until light and fluffy. This step is essential as it incorporates air into the batter, giving your cake its lovely texture. Once mixed well, add in fresh lime juice, lime zest, and eggs—beating on high speed for 2-3 minutes until everything is well combined.
Step 4: Combine Wet and Dry Mixtures
Now it’s time to bring everything together! Gradually add your dry flour mixture into the sugar mixture alternately with milk on low speed. Mix just until smooth after each addition; overmixing can lead to a dense cake.
Step 5: Pour Into Pans
Carefully pour the batter evenly into your prepared loaf pans. This step might feel simple but pouring evenly helps ensure that both cakes bake at the same rate.
Step 6: Bake Your Cakes
Bake those beauties on the middle rack for about 55-60 minutes. You’ll know they’re done when a toothpick inserted in the center comes out clean. Let them cool in their pans for about 20 minutes before transferring them onto a wire rack—this cooling period allows them to firm up just enough!
Step 7: Make the Glaze
While waiting for your cakes to cool completely (about two hours), whisk together powdered sugar, milk, and lime zest until you achieve a drizzle-able consistency. It should be thick yet pourable!
Step 8: Drizzle That Glaze
Place your cooled cakes on a rack lined with aluminum foil or parchment paper underneath. Spoon that luscious glaze over each cake allowing excess to drip down below—this creates such an appealing presentation!
Step 9: Enjoy!
Once you’ve let that glaze set up beautifully, transfer your cakes onto serving trays. Now all that’s left is to slice into these delightful loaves and share them with friends or enjoy them all by yourself!

Pro Tips for Making Key Lime Pound Cake
Baking is all about precision and love, and with these pro tips, you’ll ensure your Key Lime Pound Cake turns out perfectly every time!
- Use room temperature ingredients – Bringing your eggs and butter to room temperature helps them blend more easily, resulting in a smoother batter and a fluffier cake.
- Don’t skip the zest – Fresh lime zest adds a burst of flavor that enhances the overall citrus experience. It’s the secret ingredient that elevates your cake from good to extraordinary!
- Avoid overmixing – Once you add the flour mixture, mix just until combined. Overmixing can lead to a dense pound cake instead of a light and airy texture.
- Check for doneness – Ovens may vary, so keep an eye on your cake during the last few minutes of baking. A toothpick should come out clean when inserted into the center for perfect doneness.
- Let it cool completely – Allowing the cakes to cool on a wire rack ensures they set properly and prevents sogginess when you apply the glaze.
How to Serve Key Lime Pound Cake
Serving your Key Lime Pound Cake can be just as delightful as baking it! Here are some creative ideas to present this lovely dessert.

- Fresh Lime Slices – Thin slices of lime placed on top not only look gorgeous but also reinforce that zesty appeal.
- Toasted Coconut Flakes – Sprinkle some toasted coconut flakes for added texture and a hint of sweetness.
Side Dishes
- Tropical Fruit Salad – A refreshing mix of pineapple, mango, and berries balances the richness of the cake with their natural sweetness and acidity.
- Minty Green Salad – A simple green salad with fresh mint leaves adds brightness and makes for a refreshing contrast to the sweet pound cake.
- Vanilla Bean Ice Cream – The creamy vanilla flavor pairs perfectly with the tartness of key lime, creating a delightful mouthful in every bite.
- Lemon Sorbet – For a lighter option, serve with lemon sorbet that cleanses the palate while enhancing those citrus notes.
