How to Make Key Lime Pound Cake Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 325°F (160°C). Meanwhile, grease and flour a 10-inch bundt or tube pan thoroughly. This step ensures your cake releases easily after baking, maintaining its beautiful shape and crust.
Step 2: Cream Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar together until the mixture is light and fluffy, which takes about 4-5 minutes. This process incorporates air to create a tender and soft cake texture.
Step 3: Add Eggs One by One
Next, add the eggs one at a time, beating well after each addition. This careful mixing ensures each egg is fully incorporated, helping the batter rise uniformly and hold its structure.
Step 4: Combine Dry Ingredients Separately
In another bowl, whisk together the flour, baking powder, and salt. Mixing these dry ingredients separately guarantees even distribution, so you won’t get any lumps or uneven baking spots.
Step 5: Mix Dry Ingredients With Sour Cream Alternately
Add the dry ingredients to the butter mixture alternately with the sour cream, starting and ending with the dry ingredients. This step is key to maintaining the batter’s consistency — smooth yet sturdy with just the right moisture.
Step 6: Stir in the Key Lime and Vanilla Flavors
Gently fold in the key lime juice, key lime zest, and vanilla extract until just combined. This is where your cake gets its signature tangy freshness and aromatic charm.
Step 7: Pour Batter and Bake
Pour your batter into the prepared pan, smoothing the top lightly. Bake the cake for 65-75 minutes, or until a toothpick inserted in the center comes out clean. Patience here pays off with a perfectly cooked, golden cake.
Step 8: Cool and Glaze
Let the cake cool in the pan for 15 minutes before inverting it onto a wire rack to cool completely. While it cools, whisk together powdered sugar, key lime juice, and zest for the glaze. Drizzle this glossy, tangy glaze over the cake just before serving for an irresistible finishing touch.
How to Serve Key Lime Pound Cake Recipe
Garnishes
A little garnish can take your Key Lime Pound Cake Recipe from great to show-stopping. Imagine a scattering of additional fresh key lime zest on top, or even a few thin lime slices artistically arranged. Fresh mint leaves also brighten the presentation and add a lovely herbal note that pairs perfectly with lime.
Side Dishes
This cake shines on its own, but serving it alongside a dollop of whipped cream or a scoop of vanilla ice cream can turn a simple dessert into a luscious summer treat. For a more indulgent experience, fresh berries or a berry compote add a pleasant tartness that complements the lime beautifully.
Creative Ways to Present
Think about slicing the pound cake into finger-sized pieces and arranging them on a platter for an elegant party spread. Or, serve individual slices atop small dessert plates with a drizzle of extra glaze and a sprinkle of toasted coconut for a tropical twist. The possibilities are endless and always delicious.
Make Ahead and Storage
Storing Leftovers
This Key Lime Pound Cake Recipe keeps wonderfully when stored properly. Wrap the cooled cake tightly in plastic wrap or place it in an airtight container, then refrigerate for up to 3-4 days. This ensures the cake maintains its moist texture and fresh lime flavor without drying out.
Freezing
If you want to enjoy the cake later, it freezes beautifully. Wrap the cake or individual slices tightly in plastic wrap and then in aluminum foil to prevent freezer burn. Store in the freezer for up to 2 months. When ready to eat, thaw overnight in the refrigerator for the best texture.
Reheating
To enjoy your Key Lime Pound Cake Recipe warm, gently reheat slices in the microwave for 15-20 seconds or warm in a low oven (about 300°F) for 10 minutes. A quick toast revives the cake’s soft crumb and enhances the glaze’s tanginess for a delightful experience.
FAQs
Can I use regular lime juice instead of key lime juice?
Absolutely! Regular lime juice will work fine and still provide a lovely citrus flavor, though key lime juice offers a more distinctive tartness that defines this particular recipe.
What type of pan works best for this pound cake?
A 10-inch bundt or tube pan is ideal because it allows the cake to bake evenly and develop a beautiful shape. If you don’t have one, a loaf pan can be used, but baking times may vary.
Can I substitute sour cream with something else?
Yes, you can substitute sour cream with Greek yogurt or even buttermilk to maintain moisture and achieve that slight tang, which complements the lime flavor.
How long does the glaze stay fresh on the cake?
The glaze stays fresh and delicious for the same timeframe as the cake itself—around 3-4 days refrigerated. It might soak into the cake a bit over time, adding to the moistness.
Is this cake suitable for a special occasion?
Definitely! The Key Lime Pound Cake Recipe’s elegant appearance and bright flavors make it perfect for celebrations, whether it’s a birthday, brunch, or just a sweet treat to impress your guests.

- 2 tablespoons key lime juice

Instructions
- Preheat and Prepare Pan: Preheat your oven to 325°F (160°C). Grease and flour a 10-inch bundt or tube pan to prevent the cake from sticking.
- Cream Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy, about 4-5 minutes. This helps incorporate air for a tender crumb.
- Add Eggs: Add the eggs one at a time to the creamed mixture, beating well after each addition to ensure they are fully incorporated and the batter remains smooth.
- Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt to ensure even distribution of leavening agents and seasoning.
- Combine Dry and Wet Ingredients: Add the dry ingredients to the butter mixture alternately with the sour cream, starting and ending with the flour mixture. Mix gently to avoid overworking the batter.
- Add Flavorings: Stir in the key lime juice, key lime zest, and vanilla extract until just combined, ensuring the batter has a pronounced lime flavor without being overmixed.
- Pour Batter and Bake: Pour the batter into the prepared bundt pan and smooth the top with a spatula. Bake for 65-75 minutes, or until a toothpick inserted into the center comes out clean.
- Cool Cake: Allow the cake to cool in the pan for 15 minutes. Then invert it onto a wire rack to cool completely, preventing sogginess.

- Glaze and Serve: Drizzle the glaze evenly over the cooled cake before slicing and serving to add a tangy, sweet finishing touch.
Notes
- Make sure the butter is softened to room temperature to cream properly with the sugar.
- Use fresh key limes if possible for the best authentic flavor, though bottled key lime juice can be used as a substitute.
- Do not overmix the batter after adding the flour to keep the cake tender and moist.
- If you don’t have a bundt pan, a loaf pan can be used, but adjust baking time accordingly.
- Store any leftover cake covered at room temperature for up to 3 days or refrigerated for up to a week.
