The dense, velvety crumb of the pound cake provides a comforting base, while the vibrant Key lime juice and zest add a burst of citrusy brightness that cuts through the richness. It’s a delightful dance on your palate! Plus, this recipe is surprisingly simple to make, making it perfect for both seasoned bakers and kitchen novices alike. Whether you’re looking for a show-stopping dessert for a special occasion or simply want to treat yourself to a slice of sunshine, this Key Lime Pound Cake is sure to become a new favorite.

Ingredients:

• For the Cake:
• 3 cups all-purpose flour
• 1 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1 cup (2 sticks) unsalted butter, softened
• 2 1/2 cups granulated sugar
• 4 large eggs
• 1 cup sour cream
• 1/2 cup key lime juice (freshly squeezed is best!)
• 2 tablespoons key lime zest
• 1 teaspoon vanilla extract
• For the Key Lime Glaze:
• 2 cups powdered sugar
• 1/4 cup key lime juice (freshly squeezed)
• 1 tablespoon key lime zest
• 1 tablespoon milk (or more, to reach desired consistency)

Preparing the Key Lime Pound Cake Batter

1. Preheat and Prep: First things first, preheat your oven to 325°F (160°C). This lower temperature helps the cake bake evenly and prevents it from browning too quickly. Grease and flour a 10-inch tube pan (Bundt pan). Make sure you get into all the nooks and crannies! You can also use baking spray with flour if you prefer. This step is crucial to ensure your cake releases cleanly after baking.
2. Combine Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Whisking is important to evenly distribute the leavening agents (baking powder and baking soda) throughout the flour. This will help the cake rise properly and have a light, airy texture. Set this bowl aside for now.
3. Cream Butter and Sugar: In a separate large bowl (or the bowl of your stand mixer), cream together the softened butter and granulated sugar until light and fluffy. This usually takes about 5-7 minutes on medium speed. The mixture should be pale and almost doubled in volume. This step is vital because it incorporates air into the batter, which contributes to the cake’s tender crumb. Make sure your butter is truly softened, but not melted.
4. Add Eggs: Beat in the eggs one at a time, making sure each egg is fully incorporated before adding the next. After adding all the eggs, scrape down the sides and bottom of the bowl to ensure everything is evenly mixed. This prevents any pockets of unmixed ingredients and ensures a consistent batter.
5. Incorporate Sour Cream: Add the sour cream and mix until just combined. Sour cream adds moisture and richness to the cake, resulting in a tender and flavorful crumb. Don’t overmix at this stage, as overmixing can develop the gluten in the flour and lead to a tough cake.
6. Add Key Lime Juice, Zest, and Vanilla: Stir in the key lime juice, key lime zest, and vanilla extract. The key lime juice and zest provide the signature tangy flavor of this cake, while the vanilla extract enhances the overall sweetness and aroma.
7. Alternate Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Add the dry ingredients in three additions and the milk in two additions. Mix until just combined after each addition. Again, be careful not to overmix. Overmixing can lead to a tough cake. The alternating method helps to prevent the gluten in the flour from developing too much, resulting in a more tender cake.

Baking the Key Lime Pound Cake

1. Pour into Pan: Pour the batter into the prepared tube pan, spreading it evenly. Gently tap the pan on the counter a few times to release any air bubbles. This will help to ensure a smooth and even cake.
2. Bake: Bake in the preheated oven for 65-75 minutes, or until a wooden skewer inserted into the center comes out clean. The baking time may vary depending on your oven, so it’s important to check the cake regularly. If the top of the cake starts to brown too quickly, you can tent it with aluminum foil.
3. Cool: Let the cake cool in the pan for 10-15 minutes before inverting it onto a wire rack to cool completely. Cooling the cake in the pan allows it to set and prevents it from crumbling when you try to remove it.

Preparing the Key Lime Glaze

1. Whisk Ingredients: In a medium bowl, whisk together the powdered sugar, key lime juice, key lime zest, and milk until smooth. Add more milk, 1 tablespoon at a time, until you reach your desired consistency. The glaze should be thick enough to coat the cake but thin enough to drizzle easily.

Glazing and Serving the Key Lime Pound Cake

1. Glaze the Cake: Once the cake is completely cool, drizzle the key lime glaze evenly over the top. You can let the glaze drip down the sides for a more rustic look, or you can spread it evenly with a spatula for a more polished finish.
2. Let Glaze Set: Allow the glaze to set for at least 30 minutes before slicing and serving. This will give the glaze time to harden slightly and prevent it from running when you cut the cake.
3. Serve and Enjoy: Slice the cake and serve. This Key Lime Pound Cake is delicious on its own, but you can also serve it with a dollop of whipped cream or a scoop of vanilla ice cream. Enjoy!
