Introduction

This Moist & Tangy Key Lime Pound Cake offers a delightful twist on a classic dessert. Bursting with fresh key lime juice and zest, it strikes the perfect balance between sweet and tart. Ideal for any occasion, this cake is a refreshing treat that’s sure to impress.

Ingredients

• 1½ cups (3 sticks) unsalted butter, softened to room temperature
• 2 cups granulated sugar
• 4 large eggs, room temperature
• 1 teaspoon pure vanilla extract
• 3 cups all-purpose flour (or gluten-free 1:1 blend)
• 1 teaspoon baking powder
• ½ teaspoon baking soda
• ½ teaspoon fine sea salt
• ½ cup sour cream (or Greek yogurt for tang)
• ½ cup whole milk
• ½ cup fresh key lime juice (about 6–8 limes)
• Zest of 4 key limes (or regular limes)

For the glaze:

• 1 cup powdered sugar
• 2–3 tablespoons fresh key lime juice
• 1 teaspoon lime zest (optional)

Instructions

1. Step 1: Preheat your oven to 325°F (163°C). Grease and flour a 10-inch bundt pan or a standard loaf pan, then tap out any excess flour.
2. Step 2: In a large bowl, beat the softened butter and sugar on medium speed until light and fluffy, about 4–5 minutes. Scrape down the sides as needed.
3. Step 3: Beat in the eggs one at a time, allowing each to incorporate fully before adding the next. Mix in the vanilla extract.
4. Step 4: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
5. Step 5: With the mixer on low, add one-third of the dry ingredients to the butter mixture, then half of the sour cream. Continue alternating dry ingredients and sour cream, ending with the dry ingredients. Mix just until combined to avoid overmixing.
6. Step 6: Gently fold in the key lime juice and zest until evenly distributed. The batter will be thick and creamy.
7. Step 7: Pour the batter into the prepared pan and smooth the top. Bake for 60–75 minutes if using a loaf pan, or 50–60 minutes for a bundt pan, until a toothpick inserted near the center comes out clean or with a few moist crumbs.
8. Step 8: Let the cake cool in the pan for 15 minutes, then invert onto a wire rack to cool completely, about 1 hour.
9. Step 9: Meanwhile, whisk together the powdered sugar and 2 tablespoons of key lime juice to make a pourable glaze. Add more juice as needed to reach your desired consistency.
10. Step 10: Drizzle the glaze over the cooled cake, letting it drip down the sides. Sprinkle additional lime zest on top if desired for garnish.
11. Step 11: Slice and serve at room temperature. Enjoy your moist and tangy key lime pound cake!

Tips & Variations

• For a dairy-free version, substitute sour cream and milk with coconut yogurt and almond milk respectively.
• Using Greek yogurt instead of sour cream adds extra tang and moisture.
• Make sure all ingredients are at room temperature to ensure a smooth, well-emulsified batter.
• Add a teaspoon of lime zest directly into the glaze for a stronger lime flavor.
• If fresh key limes aren’t available, regular limes work well as a substitute.

Storage

Store leftover cake covered at room temperature for up to 3 days or refrigerate for up to 5 days. To reheat, warm slices gently in the microwave for 10–15 seconds or enjoy chilled for a denser texture. The glaze pairs beautifully with each serving whether fresh or stored.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use regular limes instead of key limes?

Yes, regular limes can be used as a substitute and will provide a similar tart, citrus flavor, though key limes are slightly more aromatic and sweeter.

How do I prevent the cake from drying out?

Be careful not to overbake and avoid overmixing the batter. Storing the cake properly in an airtight container also helps maintain its moisture.

Ingredients

Scale 1x2x3x

Cake

• 1½ cups (3 sticks) unsalted butter, softened to room temperature
• 2 cups granulated sugar
• 4 large eggs, room temperature
• 1 teaspoon pure vanilla extract
• 3 cups all-purpose flour (or gluten-free 1:1 blend)
• 1 teaspoon baking powder
• ½ teaspoon baking soda
• ½ teaspoon fine sea salt
• ½ cup sour cream (or Greek yogurt for tang)
• ½ cup whole milk
• ½ cup fresh key lime juice (about 6–8 limes)
• Zest of 4 key limes (or regular limes)

Glaze

• 1 cup powdered sugar
• 2–3 tablespoons fresh key lime juice
• 1 teaspoon lime zest (optional)

Instructions

1. Preheat & Prep: Preheat your oven to 325°F (163°C). Grease and flour a 10-inch bundt pan or a standard loaf pan, then tap out any excess flour to prevent clumping.
2. Cream Butter & Sugar: In a large bowl, use a hand mixer or stand mixer to beat the softened butter and sugar on medium speed until the mixture is light and fluffy, about 4–5 minutes. Scrape down the sides as needed to ensure even mixing.
3. Add Eggs & Vanilla: Beat in the eggs one at a time, fully incorporating each before adding the next. Then mix in the vanilla extract until combined.
4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt to evenly distribute the leavening agents and salt.
5. Alternate Dry & Wet: On low mixer speed, add one-third of the dry ingredients, followed by half of the sour cream. Continue alternating between the dry ingredients and sour cream, finishing with the dry ingredients. Mix just until combined to avoid overmixing and toughening the batter.
6. Stir in Lime: Gently fold in the fresh key lime juice and lime zest until evenly incorporated. The batter will be thick and creamy at this stage.
7. Bake: Pour the batter into the prepared pan, smoothing the top with a spatula. Bake for 60–75 minutes if using a loaf pan or 50–60 minutes if using a bundt pan. The cake is done when a toothpick inserted near the center comes out clean or with a few moist crumbs attached.
8. Cool & Glaze: Let the cake cool in the pan for 15 minutes to set. Then invert the cake onto a wire rack to cool completely, about 1 hour. Meanwhile, prepare the glaze by whisking powdered sugar with 2 tablespoons of fresh key lime juice, adding more juice as needed to create a pourable consistency.
9. Finish: Drizzle the lime glaze over the fully cooled cake, allowing it to drip down the sides naturally. Optionally, sprinkle additional lime zest on top for a vibrant garnish.
10. Serve & Enjoy: Slice and serve the cake at room temperature. Store leftovers covered at room temperature for up to 3 days or refrigerate for up to 5 days to maintain freshness.

Notes

• Room temperature ingredients help achieve a smooth, well-incorporated batter.
• Using Greek yogurt instead of sour cream offers a tangier flavor and slightly different texture.
• Gluten-free 1:1 flour blends can be used as a substitute for all-purpose flour for gluten-free options.
• Ensure not to overmix once the dry ingredients are added to avoid a dense or tough cake.
• The freshness of key limes significantly enhances the authentic citrus flavor; regular limes are a suitable alternative if key limes are unavailable.
• Leftover cake can be kept refrigerated and warmed slightly before serving to restore moisture.
