Step‑by‑Step Instructions for Key Lime Pound Cake

Step 1: Preheat Oven
Start by preheating your oven to 350°F (175°C). While it heats up, prepare two 9×5-inch loaf pans by greasing them with unsalted butter and dusting with flour to ensure your Key Lime Pound Cake releases beautifully after baking. Set aside your pans and keep an eye on that temperature!

Step 2: Sift Dry Ingredients
In a medium mixing bowl, sift together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and a pinch of salt. This process aerates the ingredients, ensuring your cake has a light texture. Once sifted, set the bowl aside, while you gather the necessary tools for the next steps.

Step 3: Cream Butter and Sugar
In a large mixing bowl, add 1 cup of softened unsalted butter and 2 cups of granulated sugar. Using an electric mixer, cream the mixture on medium speed for about 2-3 minutes, until it becomes light and fluffy, with a pale color. This step infuses air and will create a delightful texture for your Key Lime Pound Cake.

Step 4: Add Lime & Eggs
Next, blend in 1/4 cup of fresh lime juice, the zest of 2 key limes, and 4 large eggs. Beat on low speed until all ingredients are fully incorporated, taking about 1-2 minutes. You should have a smooth, vibrant mixture that captures the refreshing essence of key limes—perfect for your cake!

Step 5: Combine Mixtures
Gradually add the sifted dry ingredients to the butter mixture, alternating with 1/2 cup of milk. Start and end with the dry ingredients, mixing on low until everything is just combined, about 1-2 minutes. Take care not to overmix, as you want a tender crumb for your Key Lime Pound Cake.

Step 6: Bake
Pour the batter evenly into the prepared loaf pans. Place them in the preheated oven and bake for 55–60 minutes. The cakes are ready when a toothpick inserted in the center comes out clean and the top is lightly golden. Your kitchen will soon fill with a delightful aroma!

Step 7: Cool Cakes
After baking, let the cakes cool in their pans for 20 minutes. Then, gently transfer them to a wire rack to cool completely for about 2 hours. This cooling period allows the flavors to settle, enhancing your Key Lime Pound Cake’s taste and texture.

Step 8: Prepare Glaze
While the cakes cool, whisk together 1 cup of powdered sugar, 2 tablespoons of milk, and the zest of 1 key lime in a small bowl. Continue blending until the glaze is smooth and can be drizzled easily. Adjust the consistency by adding more milk or powdered sugar as needed until it’s just right.

Step 9: Glaze Cakes
Once the cakes are completely cool, spoon the glaze over the top of each loaf, allowing it to beautifully drip down the sides. Let the glaze set for a few minutes before slicing into your luscious Key Lime Pound Cake, ready to be enjoyed!

Key Lime Pound Cake Recipe FAQs

How do I choose the best key limes for my cake?
Absolutely! When selecting key limes, look for fruits that are firm and slightly soft to the touch, with a vibrant green color. Avoid limes with dark spots or blemishes, as these may indicate overripeness. The juice content is higher in limes that have a smoother skin, so a little poke is worthwhile—a perfect key lime brings a balance of tartness and sweetness to your Key Lime Pound Cake.

What’s the best way to store Key Lime Pound Cake?
You can store your Key Lime Pound Cake in an airtight container at room temperature for up to 5 days, keeping it moist and delicious. If you’re looking to prolong its freshness, tightly wrap the cake in plastic wrap and then aluminum foil, storing it in the fridge for up to a week. Just be sure to let it come to room temperature before serving for that fresh-baked taste!

Can I freeze Key Lime Pound Cake, and how should I do it?
Yes, you can absolutely freeze your Key Lime Pound Cake for up to 6 months! To do this, wrap the cooled cakes tightly in plastic wrap, ensuring no air is escaping, then place them in aluminum foil for extra protection against freezer burn. When you’re ready to enjoy, simply thaw them overnight in the fridge, and you’ll have a slice of sunshine ready to delight your palate.

What should I do if my Key Lime Pound Cake is too dense?
If your Key Lime Pound Cake turns out denser than expected, it might be due to overmixing the batter after adding flour. For the next batch, remember to mix until just combined—this will help create a lighter cake. Additionally, ensure your ingredients are at room temperature before mixing to achieve that airy texture.

Are there any dietary considerations with this recipe?
Very much! The Key Lime Pound Cake contains eggs and dairy, so if you’re baking for someone with allergies or dietary restrictions, consider using flax eggs as a vegan substitute and almond milk for a dairy-free option. Keep in mind that you can also substitute with gluten-free flour if you want a gluten-free version.

Can pets have Key Lime Pound Cake?
Nope! While the cake may seem tempting to share, key limes and dairy can upset a pet’s stomach. It’s best to keep this delicious treat for yourself and opt for pet-friendly snacks if you want to share the love with your furry friends!
