¼ teaspoon salt
(Hint: Check out the full list of ingredients and measurements in the recipe card below.)
Directions
-
Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or a Bundt pan.
-
In a medium bowl, whisk together the all-purpose flour and salt. Set aside.
-
In a large mixing bowl, cream together the butter and sugar until light and fluffy, about 3-4 minutes.
-
Add the eggs one at a time, beating well after each addition. Then, stir in the key lime zest and juice.
-
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix the batter.
-
Pour the batter into the prepared pan and smooth the top with a spatula.
-
Bake in the preheated oven for 55-65 minutes (if using a loaf pan) or 45-55 minutes (if using a Bundt pan), or until a toothpick inserted into the center comes out clean.
-
Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
-
Serve as is or top with a dusting of powdered sugar or a glaze made from powdered sugar and key lime juice for extra sweetness.
Servings and Timing
This recipe yields around 10-12 servings, depending on how thick you slice the cake. Prep time is about 15 minutes, and baking time takes 45-65 minutes, depending on the pan size. It’s easy to make, and the cake is perfect for both casual and special occasions.
Variations
This cake is easy to adapt if you want to experiment with different flavors:
-
If you prefer a different citrus flavor, you can swap the key limes for regular limes or even lemons for a slightly different taste.
-
For added texture and flavor, you can fold in some chopped macadamia nuts or shredded coconut to the batter.
-
You can also drizzle a simple glaze made from powdered sugar, key lime juice, and a little bit of milk over the cooled cake for extra sweetness.
Storage/Reheating
This cake keeps well when stored in an airtight container at room temperature for about 3-4 days. If you want it to last longer, you can refrigerate it for up to a week. For the best flavor, I recommend serving it at room temperature, but you can warm it slightly in the microwave or oven if you prefer it a bit warmer.
FAQs
Can I make this cake without key limes?
Yes, you can use regular limes if key limes are unavailable. The flavor may be slightly different, but the cake will still have that lovely citrusy zing.
Can I freeze the Key Lime Pound Cake?
Yes, this cake freezes beautifully! I usually slice it into individual portions, wrap them tightly in plastic wrap, and store them in a freezer-safe bag. It will keep for up to 2-3 months in the freezer. Just thaw at room temperature when you’re ready to enjoy it.
Can I make this cake dairy-free?
Yes, you can substitute the butter with dairy-free butter or oil, and you can also use a dairy-free milk alternative. The texture and flavor will be a bit different, but it should still work well.
Can I add a glaze to this cake?
Absolutely! A simple glaze made from powdered sugar and key lime juice can be drizzled over the cake for an added sweetness and citrus flavor. It’s a great way to enhance the flavor and appearance of the cake.
Can I use whole wheat flour instead of all-purpose flour?
You can use whole wheat flour, but the cake will have a denser texture. If you prefer a lighter texture, I recommend sticking to all-purpose flour or using a mix of whole wheat and all-purpose flour.

This Key Lime Pound Cake is a simple yet elegant dessert that combines the richness of pound cake with the bright, tangy flavor of key limes.
