Step‑by‑Step Instructions for Key Lime Pound Cake

Step 1: Preheat and Prepare
Begin by preheating your oven to 325°F (165°C). While the oven warms, grab a 10-inch tube pan and generously grease and flour it, ensuring an even coating. This will prevent your Key Lime Pound Cake from sticking once it’s baked. A well-prepared pan is key to a perfect cake!

Step 2: Cream the Butter and Sugar
In a large mixing bowl, use an electric mixer to cream together 1 cup of softened unsalted butter and 2 cups of granulated sugar. Beat them for about 3-4 minutes until the mixture becomes light and fluffy. This adds air for leavening, giving the cake a beautiful texture and rich flavor.

Step 3: Add the Eggs
One at a time, incorporate 4 room-temperature eggs into the creamed mixture, taking care to mix well after each addition. This step is vital for the structure of your Key Lime Pound Cake. The mixture should be smooth and well-blended before moving on to the next step.

Step 4: Combine Dry Ingredients
In a separate bowl, whisk together 3 cups of all-purpose flour and 1 teaspoon of baking soda. Gradually add this dry mixture to the wet batter, alternating with 1 ½ cups of buttermilk. Start and finish with the flour mixture. Mix until just combined to avoid overworking the batter, ensuring a light and tender cake.

Step 5: Infuse with Lime
Gently fold in the juice and zest of 3-4 fresh limes into your batter, allowing the refreshing citrus flavor to fully integrate. This is the heart of the Key Lime Pound Cake, bringing zest and brightness to each bite. Be careful not to overmix during this step.

Step 6: Pour and Smooth the Batter
Transfer the luscious cake batter into the prepared tube pan, using a spatula to spread it evenly. Ensure the batter is well-distributed to promote even baking. Visualize a smooth top as you prepare to bake this delightful dessert.

Step 7: Bake to Perfection
Place the pan in the preheated oven and bake for 60-70 minutes. To check for doneness, insert a toothpick into the center; if it comes out clean, your Key Lime Pound Cake is ready. If it requires more time, continue to bake and check every 5 minutes.

Step 8: Cool and Transfer
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. This step helps it firm up slightly. Then, carefully invert the cake onto a wire rack to cool completely. This allows air to circulate around the cake, keeping its texture just right.
