Step-by-Step Instructions
Follow these steps carefully for the perfect Key Lime Pound Cake.
Step 1: Preheat Oven and Prepare Pan
- Preheat the oven to 325°F (165°C).
- Grease and flour a 10-inch tube pan thoroughly to prevent sticking.
Step 2: Cream Butter and Sugar
- In a large mixing bowl, cream together the butter and sugar using an electric mixer on medium speed.
- Beat until the mixture is light and fluffy, about 3–5 minutes.
Step 3: Add Eggs
- Beat in the eggs one at a time, mixing well after each addition to ensure they are fully incorporated.
Step 4: Combine Dry Ingredients
- In a separate bowl, combine flour and baking soda.
- Gradually add the dry mixture to the creamed butter and sugar alternately with the buttermilk, beginning and ending with the flour mixture.
- Mix until smooth and fully combined, but avoid overmixing to maintain a tender texture.
Step 5: Add Lime Flavor
- Stir in lime juice and lime zest until evenly distributed.
- This step ensures the cake has a bright, aromatic citrus flavor in every bite.
Step 6: Pour and Bake
- Pour the batter into the prepared tube pan, spreading it evenly.

Step 7: Cool and Serve
- Allow the cake to cool in the pan for 10 minutes.
- Carefully remove from the pan and transfer to a wire rack to cool completely.
- Optionally, drizzle a lime glaze over the cooled cake for enhanced flavor.
