How to Make Key Lime Pound Cake

Step 1: Prepare Ingredients and Pan

Preheat your oven to 325°F (163°C). Grease and flour a 9×5 inch loaf pan to ensure the cake releases smoothly after baking. Gather all ingredients measured and ready to go to streamline the process.

Step 2: Cream Butter and Sugar

In a large mixing bowl, beat the butter and granulated sugar together until the mixture is pale, light, and fluffy. This step incorporates air, essential for a tender texture.

Step 3: Add Eggs and Vanilla

Beat in the eggs one at a time, followed by the vanilla extract. Make sure each egg is fully incorporated before adding the next to maintain batter consistency.

Step 4: Mix Dry Ingredients Separately

In another bowl, whisk together the all-purpose flour, baking powder, and a pinch of salt. This ensures even distribution of the leavening agents.

Step 5: Combine Wet and Dry Ingredients Alternately

Add the dry ingredients to the butter mixture in three additions, alternating with the sour cream. Start and end with the dry ingredients, mixing gently to avoid overworking the batter.

Step 6: Incorporate Key Lime Juice and Zest

Fold in fresh key lime juice and zest, distributing the citrus flavor evenly throughout the batter without deflating it.

Step 7: Bake the Pound Cake

Pour the batter into the prepared loaf pan and gently smooth the top. Bake for approximately 60-70 minutes, or until a toothpick inserted in the center comes out clean.

Step 8: Prepare the Glaze

While the cake cools slightly, mix powdered sugar with a splash of key lime juice to create a smooth glaze. Drizzle over the warm cake for added tang and shine.

Pro Tips for Making Key Lime Pound Cake

• Fresh is Best: Always use fresh key limes for zest and juice to avoid artificial flavors.
• Room Temperature Ingredients: Allow butter, eggs, and sour cream to come to room temperature for better blending.
• Do Not Overmix: Gently fold the ingredients to keep the cake moist and fluffy.
• Check for Doneness Early: Start checking at 55 minutes to prevent overbaking and dryness.
• Cooling Time Matters: Let the cake cool in the pan for 15 minutes before transferring to a rack to keep the shape intact.
