2 cups granulated sugar – Sweetness is key here; it helps balance the zesty lime, making the cake perfectly delightful.
4 large eggs – They bind everything together and provide structure and moisture for this luscious cake.
3 cups all-purpose flour – Essential for building the cake’s body, use a good quality flour for the best results.
1/2 teaspoon baking soda – This small amount gives the cake the rise it needs for that perfect pound cake texture.
1 cup buttermilk – Its tanginess enhances the lime flavor while keeping the cake moist.

How to Make Key Lime Pound Cake
Follow these simple steps to prepare this delicious Key Lime Pound Cake:
Step 1: Preheat and Prep
Preheat your oven to 325°F (165°C) and grease a 10-inch tube pan well. This ensures that your cake will release effortlessly once it’s baked.
Step 2: Cream Butter and Sugar
In a large mixing bowl, cream together the softened butter and sugar until the mixture is light and fluffy. You want it to look pale and airy, as this will help give your cake a lovely crumb.
Step 3: Add Eggs
Beat in the eggs one at a time, ensuring each egg is fully incorporated before adding the next. This method helps create a smooth batter without lumps.
Step 4: Combine Dry Ingredients
In another bowl, whisk together the flour and baking soda. This step is crucial because it evenly distributes the baking soda, ensuring your cake rises uniformly.
Step 5: Mix Ingredients Together
Gradually add the dry mixture alternately with the buttermilk into the creamed butter and sugar mixture, stirring gently. This method prevents the batter from becoming tough.
Step 6: Add Lime Flavor
Fold in the fresh lime juice and lime zest until just combined. Be careful not to overmix, as you want to retain that fluffiness in the cake.
Pour the batter into the prepared pan, smoothing the top. Bake for 60-70 minutes or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Now that your Key Lime Pound Cake has cooled, slice it up, pour yourself a refreshing iced tea, and enjoy a bit of your own slice of paradise! It’s perfect for gatherings, dessert after dinner, or simply indulging on a quiet afternoon. Your taste buds will thank you!
