There is something undeniably magical about the bright, tangy aroma of citrus filling the kitchen on a sunny afternoon. This key lime pound cake recipe has become my absolute favorite way to capture that sunshine in a dessert, balancing tart zest with buttery richness.

I remember the first time I baked this cake for a casual weekend gathering. I was looking for a dessert that felt comforting yet vibrant enough to wake up the palate after a heavy meal. The moment I drizzled that zesty glaze over the warm, golden crust, I knew I had found a keeper.

It reminds me of the joy I feel when making other fruit-forward treats, like these cherry coconut magic bars. Sharing a slice of this dense, moist cake with friends over coffee creates an instant sense of connection and warmth. It is simple enough for a weekday treat but elegant enough to serve at a celebration.

Ingredients

1 cup (2 sticks) unsalted butter, softened to room temperature
2 cups granulated sugar
4 large eggs, room temperature
3 cups all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon salt
1/2 cup sour cream, room temperature
1/4 cup fresh key lime juice
2 tablespoons fresh key lime zest
1 teaspoon vanilla extract
1 1/2 cups powdered sugar (for glaze)
2-3 tablespoons fresh key lime juice (for glaze)
1 teaspoon fresh key lime zest (for garnish)

Directions

Step 1

Preheat your oven to 325°F (165°C) to ensure a gentle, even bake. Generously grease and flour a 10-inch Bundt pan or spray with baking spray containing flour to ensure the cake releases perfectly later on.

Step 2

In a large mixing bowl or stand mixer fitted with the paddle attachment, cream the softened butter and granulated sugar together. Beat on medium-high speed for about 5 minutes until the mixture transforms into a pale yellow and fluffy consistency.

Step 3

Add the eggs one at a time, making sure to beat well after each addition. Scrape down the sides of the bowl frequently to ensure all the ingredients are fully incorporated into the batter.

Step 4

In a separate medium bowl, whisk together the flour, baking powder, and salt to aerate the dry ingredients. In a small cup or bowl, mix the 1/4 cup key lime juice, sour cream, and vanilla extract until blended.

Step 5

Reduce the mixer speed to low to prevent flour from flying out. Add the flour mixture to the butter mixture in three parts, alternating with the sour cream mixture, beginning and ending with the flour. Mix only until just combined to avoid developing too much gluten, which can lead to a dense cake.

Step 6

Gently fold in the 2 tablespoons of key lime zest by hand using a spatula to distribute it evenly without overworking the batter. Pour the batter into the prepared Bundt pan and smooth the top evenly with your spatula.

Step 7

Bake for 55 to 65 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs attached. If you notice the top browning too quickly, tent it loosely with aluminum foil after the 40-minute mark.

Step 8

Remove the cake from the oven and let it cool in the pan for 10-15 minutes to set the structure. Carefully invert the cake onto a wire rack to cool completely before applying the glaze.

Step 9

To make the glaze, whisk the powdered sugar with 2 tablespoons of key lime juice in a small bowl until smooth. Add more juice a teaspoon at a time until you reach a pourable consistency, then drizzle over the cooled cake and sprinkle with the remaining zest.

Variations, pairings, and serving ideas

Variations

You can easily twist this key lime pound cake recipe by swapping the citrus. Try using lemons or blood oranges for a different color and flavor profile that is equally refreshing. The base batter is robust enough to handle any citrus zest you have on hand.

For a tropical flair, consider adding a half cup of shredded coconut to the batter. The texture of the coconut pairs beautifully with the dense crumb of the cake. It adds a subtle chewiness that surprises the palate.

If you enjoy a bit of crunch, fold in a tablespoon of poppy seeds along with the lime zest. This adds a lovely visual speckle to the yellow interior. It also provides a classic texture contrast that complements the smooth glaze.

Pairings

This cake pairs exceptionally well with a hot cup of Earl Grey tea. The bergamot notes in the tea echo the citrus elements in the cake. It creates a sophisticated afternoon tea experience.

For a morning treat, serve a slice alongside a dark roast coffee. The bitterness of the coffee cuts through the sweet glaze and buttery cake perfectly. It is a wonderful way to start a slow weekend morning.

You can also serve this alongside a fresh berry salad. The tartness of raspberries or blackberries highlights the lime flavor without overpowering it. It adds a fresh, juicy element to the dessert plate.

Serving ideas

Present this cake on a simple white platter to let the vibrant green zest garnish pop. A clean presentation highlights the elegance of the Bundt shape. It makes for a stunning centerpiece on any dessert table.

For an extra indulgent touch, serve each slice with a dollop of unsweetened whipped cream. The creaminess balances the tart glaze beautifully. It adds a cloud-like texture against the dense pound cake.

If you prefer a simpler look, skip the glaze and just dust the cake with powdered sugar. This is perfect for those who prefer a less sweet dessert. It gives the cake a rustic, snow-dusted appearance.

Storage and make-ahead tips

Storage

Store any leftovers from this key lime pound cake recipe in an airtight container at room temperature. The high sugar and fat content allows it to stay fresh and moist for up to 3 days. Ensure the container is sealed tight to prevent the cut sides from drying out.

For longer storage, you can freeze individual slices. Wrap each slice tightly in plastic wrap and then place them in a zip-top freezer bag. They can be frozen for up to 3 months and thawed at room temperature when a craving strikes.

If you have glazed the cake, avoid stacking slices on top of each other. The glaze can become sticky and mar the appearance of the pieces underneath. Use parchment paper between layers if stacking is necessary.

Make-ahead

This pound cake actually tastes better the day after baking. The flavors of the butter and lime have more time to meld together. You can bake the cake one day in advance and keep it covered at room temperature.

If you are prepping for a party, you can make the glaze ahead of time as well. Store it in a small airtight container in the refrigerator. When you are ready to serve, simply whisk it briefly and drizzle it over the cake.

You can also freeze the entire unglazed cake for a future event. Wrap the cooled whole cake in double layers of plastic wrap and foil. Thaw it on the counter overnight before glazing and serving.

Common mistakes when making Moist Key Lime Pound Cake with Zesty Glaze

Using cold ingredients is a frequent error that prevents the batter from emulsifying properly. Ensure your butter, eggs, and sour cream are truly at room temperature for a smooth batter.
Overmixing the flour is the quickest way to ruin a key lime pound cake recipe and end up with a tough texture. Stop mixing as soon as the white streaks of flour disappear.
Opening the oven door too often can cause the cake to sink in the middle. Trust the timer and only check for doneness toward the end of the baking time.
Glazing the cake while it is still hot will cause the icing to melt and slide right off. Be patient and wait until the cake is completely cool to touch.
Using bottled lime juice instead of fresh key limes can result in a flatter flavor profile. While acceptable in a pinch, fresh juice provides the signature aromatic zestiness.

Final notes

Mastering this key lime pound cake recipe is all about patience and using quality ingredients. Taking the time to cream the butter and sugar properly sets the foundation for that classic pound cake texture. Do not rush the cooling process, as it ensures clean slices every time.

This cake is incredibly versatile and works for almost any season, despite its summery flavor profile. The bright citrus notes are a welcome pick-me-up during colder months as well. It brings a little bit of sunshine to the table whenever you serve it.

I hope you enjoy baking this as much as I do. It is a recipe that rewards you with a home filled with incredible scents and happy faces. Happy baking!
