- 1 ½ cups all-purpose flour
- 1 cup granulated sugar
- ½ cup unsalted butter, softened
- 2 large eggs
- ½ cup fresh key lime juice (about 4-5 key limes)
- 1 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
- 1 tsp vanilla extract (halal-certified)
- Zest of 2 key limes

Step-by-Step Instructions
Here’s how to create the perfect Key Lime Pound Cake for your loved ones:
- Preheat the Oven: Preheat your oven to 350°F (175°C). This step is crucial as it ensures an even bake.
- Prepare the Pan: Grease a 9×5 inch loaf pan with butter or cooking spray to prevent sticking.
- Mix Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy, about 3-5 minutes.
- Add Eggs: Beat in the eggs one at a time, mixing well after each addition. Don’t forget to scrape down the sides of the bowl!
- Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, baking soda, and salt.
- Alternate with Wet Ingredients: Gradually add the dry mixture and key lime juice to the creamed mixture, starting and ending with the flour mixture. Mix until just combined—overmixing can lead to a dense cake.
- Add Flavor Elements: Stir in the key lime zest and vanilla extract gently to incorporate the flavor.
- Pour and Bake: Pour the batter into the prepared loaf pan and smooth the top. Bake for 50-60 minutes or until a skewer inserted into the center comes out clean.
- Cool Down: Once baked, allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
- Serve and Enjoy! Once cooled, slice your cake and serve it plain or with a drizzle of glaze.
Top Tips for Perfecting Key Lime Pound Cake
- Substitutions: If key limes are hard to find, regular limes can work in a pinch, but the flavor will be slightly different.
- Temperature Check: Ensure that your butter is softened to room temperature for better mixing.
- Avoid Overmixing: This can lead to a tough texture—mix just until combined.
- Test for Doneness: Use a toothpick to check; it should come out clean or with a few moist crumbs.
- Chill the Batter: If you want an even more intense key lime flavor, chill the batter for about 30 minutes before baking.
Storing and Reheating Tips
To store your Key Lime Pound Cake, wrap it tightly in plastic wrap or place it in an airtight container. It’ll keep well at room temperature for 2-3 days or in the fridge for up to a week. For longer storage, you can even freeze it for up to 3 months—just ensure it’s wrapped well.
When you’re ready to enjoy your cake, let it come to room temperature before serving, or pop it in the microwave for about 10-15 seconds for that fresh-out-of-the-oven sensation.
So there you have it! A simple, delightful Key Lime Pound Cake that will become a beloved staple in your home. Enjoy making and sharing this delicious treat—it truly brings everyone together!
