How to Make Key Lime Pound Cake – Step-by-Step Directions
Step 1 – Prepare Ingredients
Begin by gathering all the ingredients you need for the Key Lime Pound Cake. Make sure to measure them accurately for the best results. Preheat your oven to 350°F (175°C) and grease and flour a bundt pan or two loaf pans, depending on your preference.
Step 2 – Cream the Butter and Sugar
In a large mixing bowl, cream the softened butter and granulated sugar together until the mixture is light and fluffy. This should take about 3-5 minutes using an electric mixer. Ensuring proper creaming will result in a light, airy cake.
Step 3 – Add Eggs
One at a time, add the eggs to the butter and sugar mixture. Beat well after each addition until fully incorporated. This step is essential for a light texture in your Key Lime Pound Cake.
Step 4 – Mix the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. It’s crucial to combine these thoroughly to ensure even distribution of ingredients.
Step 5 – Alternate Dry Ingredients and Sour Cream
With the mixer on low speed, alternate adding the dry flour mixture and sour cream to the wet ingredients in the mixing bowl, starting and ending with the flour mixture. Each addition should be mixed just until incorporated. Be careful not to overmix, as this can lead to a dense cake.
Step 6 – Add Key Lime Juice and Zest
Once the batter is smooth, gently fold in the Key lime juice and zest. This is where the magic happens, as the tangy ingredients infuse the batter with refreshing flavor. Make sure they are well distributed throughout the batter.
Step 7 – Pour into the Pan
Carefully pour the batter into the prepared pan(s), smoothing out the top with a spatula for an even bake. If using a bundt pan, gently tap it on the counter to release any air bubbles that may be trapped in the batter.
Step 8 – Bake
Place the pan in the preheated oven and bake for about 60-75 minutes, or until a toothpick inserted into the center comes out clean. Keep an eye on your cake to prevent overbaking, as every oven is different.
Step 9 – Cool
Once baked, remove the Key Lime Pound Cake from the oven and let it cool in the pan for about 15 minutes. This allows the cake to set before transferring it to a wire rack to cool completely.
Step 10 – Glaze or Serve
Optionally, prepare a glaze with powdered sugar and Key lime juice to drizzle over the cooled cake for added sweetness and a beautiful finish. Serve it on a platter, or slice it individually for your guests.

Tips & Tricks for Key Lime Pound Cake
Mistakes to Avoid
1 – Not Measuring Ingredients Accurately: Accuracy in measurements, especially with flour, can greatly affect the cake’s texture. Use a kitchen scale for best results.
2 – Overmixing the Batter: Mixing too long can result in a tough cake. Mix just until combined for a tender crumb.
3 – Skipping the Creaming Step: Don’t rush the creaming of butter and sugar. This is crucial for achieving a light and airy cake.
4 – Opening the Oven Door Too Early: Avoid checking the cake before the minimum bake time. Doing so can interrupt the rise and affect texture.
5 – Not Cooling Properly: Allow the cake to cool in the pan slightly before transferring it. This lets it set for easier slicing.
Extra Tips for Better Results
- For added flavor, consider incorporating a few drops of vanilla extract into the glaze.
- To enhance the moisture content, consider brushing the cooled cake with a mixture of Key lime juice and simple syrup.
- When incorporating zest, use a microplane for a fine texture that distributes flavor evenly throughout the cake.
