Ingredients You’ll Need
The beauty of this Key Lime Pound Cake Recipe comes from its straightforward yet thoughtfully chosen ingredients. Each one plays a crucial role, whether it’s lending moisture, tender crumb, or that distinct lime spark that defines the cake’s vibrant personality.
- 1 cup butter, softened: Provides a rich and creamy base essential for the cake’s tender texture.
- 2 cups sugar: Sweetens the cake and helps achieve a beautiful golden crust.
- 4 large eggs: Bind everything together while adding structure and richness.
- 3 cups all-purpose flour: Builds the hearty body for this classic pound cake’s dense crumb.
- 1/2 tsp baking soda: A little lift to keep the cake from being too heavy.
- 1 cup buttermilk: Adds moisture and a subtle tang that complements the lime flavors perfectly.

- 1 tsp lime zest: Intensifies the lime essence and adds a touch of aromatic complexity.
How to Make Key Lime Pound Cake Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 325°F (165°C). This temperature ensures that the cake bakes evenly without drying out. Grease and flour a 10-inch tube pan so the cake doesn’t stick and has that perfect, easy release when it’s done.
Step 2: Cream Butter and Sugar
In a large bowl, beat the softened butter and sugar together until the mixture is light and fluffy. This step is key because it incorporates air that helps the pound cake achieve a soft yet dense texture. Don’t rush this; a few minutes with a hand or stand mixer will do wonders.
Step 3: Add the Eggs
Beat in the eggs one at a time, making sure each egg is fully incorporated before adding the next. This gradual addition shields the mixture from curdling and keeps the batter smooth and cohesive.
Step 4: Combine Dry and Wet Ingredients
In a separate bowl, whisk together the flour and baking soda. Then, alternately add this dry mix and the buttermilk to your creamed butter mixture, starting and ending with the dry ingredients. This technique creates a tender crumb without making the batter too dense or too liquid.
Step 5: Incorporate Lime Juice and Zest
Gently fold in the fresh lime juice and lime zest. This final addition is crucial because it infuses the batter with a fresh citrus punch that makes this Key Lime Pound Cake Recipe stand out. Be sure to use freshly squeezed juice for the best flavor.
Step 6: Bake and Cool
Pour your luscious batter into the prepared tube pan and bake for 60 to 70 minutes, or until a toothpick inserted in the center comes out clean. This slow bake at a moderate temperature ensures the cake cooks evenly and remains moist. Let it cool in the pan for 10 minutes before turning it out onto a wire rack to cool completely.
How to Serve Key Lime Pound Cake Recipe
Garnishes
To enhance the fresh lime experience, sprinkle a little extra lime zest on top or drizzle with a light glaze made from powdered sugar and lime juice. You can also add some fresh whipped cream or a handful of toasted coconut flakes for extra flavor and texture contrasts.
Side Dishes
This cake pairs delightfully well with simple sides like a scoop of vanilla ice cream or a bowl of fresh berries. The cool creaminess of ice cream or the juicy sweetness of berries creates a perfect harmony with the tart lime notes in the cake.
Creative Ways to Present
Try serving slices of this Key Lime Pound Cake Recipe with a dollop of tangy Greek yogurt and a few mint leaves to make it feel like a sophisticated dessert. For special occasions, you could even turn it into an ice cream cake or layer it with lime curd and whipped cream for a decadent trifle.
Make Ahead and Storage
Storing Leftovers
If you have leftovers (and with this cake, that might happen!), wrap it tightly in plastic wrap or store in an airtight container at room temperature for up to 3 days. Keeping it sealed will maintain its moist texture and fresh lime flavor.
Freezing
You can freeze this pound cake, wrapped well in plastic and then foil, for up to 2 months. Thaw it overnight in the fridge, and you’ll find it retains almost all of its wonderful texture and flavor when brought back to room temperature.
Reheating
For the best experience, warm slices gently in the microwave for about 15 seconds or in a low oven, wrapped in foil, until just warmed through. This will revive that fresh-baked aroma and softness, making each bite feel like it just came out of the oven.
FAQs
Can I substitute regular milk for buttermilk in this recipe?
Yes, you can use regular milk mixed with a tablespoon of vinegar or lemon juice to mimic buttermilk’s acidity and texture. Let it sit for 5 minutes before adding, which will help maintain the cake’s tender crumb.
What type of lime is best for Key Lime Pound Cake Recipe?
Traditional Key limes are smaller and more aromatic than regular limes, but if you can’t find them, regular Persian limes work perfectly well and still deliver great flavor.
Is this pound cake dense or light?
This pound cake strikes a lovely balance—dense enough to be rich and satisfying but lightened by the buttermilk and lime, which keep it tender and moist without being heavy.
Can I make this cake gluten-free?
Absolutely! Substitute the all-purpose flour with a gluten-free flour blend and be sure to include a binding agent like xanthan gum if it’s not included in your blend to achieve the best texture.
How long does the baking process take?
The baking time is usually between 60 and 70 minutes at 325°F (165°C), but since ovens vary, start checking around 60 minutes with a toothpick to avoid over-baking.
