Let’s start making Key lime pound cake
Ingredients
-
-
- 2.5 cups all-purpose flour
-
- 1 teaspoon baking powder
-
- ½ teaspoon salt
-
- 1 cup (2 sticks) unsalted butter, softened
-
- 2 cups granulated sugar
-
- 4 large eggs, room temperature
-
- ½ cup Key lime juice (freshly squeezed is best!)
-
- 2 tablespoons Key lime zest
-
- ½ cup milk (whole milk recommended)
-
- 1 teaspoon vanilla extract
-
For the Glaze:
-
-
-
- 2 cups powdered sugar
-
- 4 tablespoons Key lime juice
-
- 1 tablespoon Key lime zest (optional, for extra zing!)
-
-
Instructions
-
-
-
- Preheat your oven to 325°F (160°C). Grease and flour a 10-cup Bundt pan or a 9×5 inch loaf pan. Make sure you get into all those nooks and crannies! A baking spray with flour works really well here.
-
- In a medium bowl, whisk together the flour, baking powder, and salt. Set this aside for a moment.
-
- In a large bowl, using an electric mixer, cream together the softened butter and granulated sugar until it’s light and fluffy. This should take about 3-5 minutes. Don’t rush this step – it’s key for a tender cake.
-
- Add the eggs one at a time, beating well after each addition. Scrape down the sides of the bowl often to make sure everything gets mixed in.
-
- In a separate small bowl or measuring cup, mix the Key lime juice, Key lime zest, milk, and vanilla extract. This creates a vibrant, citrusy liquid mix.
-
- With the mixer on low speed, gradually add the dry ingredients to the wet ingredients, alternating with the liquid Key lime mixture. Start and end with the dry ingredients. Be careful not to overmix; stop as soon as everything is just combined. Overmixing can lead to a tough cake, and we don’t want that!
-
- Pour the batter evenly into your prepared Bundt pan. Smooth the top with a spatula.
-
- Bake for 70-80 minutes, or until a wooden skewer inserted into the center of the cake comes out clean. Baking times can vary, so keep an eye on it!
-
- Once baked, remove the cake from the oven and let it cool in the pan for about 10-15 minutes before inverting it onto a wire rack to cool completely. Patience is a virtue, especially with pound cake!
-
- While the cake cools, prepare the glaze: Whisk together the powdered sugar, Key lime juice, and optional zest in a small bowl until smooth. If it’s too thick, add a tiny bit more lime juice; if too thin, add a bit more powdered sugar.
-
- Once the cake is completely cool, drizzle the glaze over the top, letting it drip down the sides. Slice and serve! The tangy scent is just divine.

Expert Tips for Success: Bake Like a Pro!
Ok, you have the recipe, but occasionally a bit of inside information can put the difference between you and me. I will give you some of my best tips to ensure your Key Lime Pound Cake comes out to perfection. We desire oohs and aahs not uh-ohs.
And be frank, baking is not always foolproof. The initial occasion when I sampled a Key lime cake, I had assumed that any lime juice would suffice. Big mistake! I was left with a cake that merely tasted like lime and not the vibrant, clear lime that Key limes provide. It had not that distinctive, almost floral tartness. Fresh Key lime juice is another uncompromising measure to take in order to have that authentic Key lime experience. Believe me, you will not regret it in your taste-buds.
Getting That Perfect Texture
A great pound cake is all about its texture: dense yet moist, with a fine crumb. It’s a balance!
- Room Temperature Ingredients: This is a big one. Softened butter, room temperature eggs, and milk combine better, creating a smooth batter that holds air. Cold ingredients can make your batter lumpy and result in a denser cake. Take them out of the fridge at least an hour before you start baking.
- Don’t Overmix: Once you add the flour, mix just until combined. Overmixing develops the gluten in the flour too much, which can lead to a tough, dry cake. Nobody wants a rubbery pound cake!
- Grease and Flour Your Pan Properly: Especially with a Bundt pan, this is incredibly important. Use shortening or butter to coat every crevice, then dust with flour, tapping out any excess. This helps prevent sticking and keeps your beautiful cake intact.
Pro Tip: For the absolute best Key lime flavor, use a microplane to zest your Key limes directly into the sugar before creaming it with the butter. This helps release the citrus oils, letting the zest truly infuse the sugar with its bright, aromatic flavor. You’ll notice a huge difference!
Variations & Add-ins
Feeling adventurous? Here are a few ways to switch things up without messing with the core recipe too much:
- Coconut Twist: Add ½ cup shredded coconut to the batter for a tropical vibe. A touch of coconut extract in the glaze could also be delightful.
- Extra Glaze: If you love a really thick glaze, simply double the glaze ingredients. You can never have too much sweetness and tang!
- Cream Cheese Glaze: For a richer, tangier topping, whisk 4 ounces softened cream cheese with 2 cups powdered sugar, 2 tablespoons Key lime juice, and a splash of milk until smooth.
- Berry Good: Gently fold in 1 cup of fresh blueberries or raspberries into the batter right before pouring it into the pan. Toss them with a tablespoon of flour first to prevent them from sinking.
Storage & Freezing
So, you’ve made this incredible cake, and now you want to make it last (or hide it from eager hands). Here’s how to store it:
- Countertop: Store the cake, covered loosely with plastic wrap or in an airtight container, at room temperature for up to 3-4 days. This cake stays wonderfully moist!
- Refrigerator: If you prefer it chilled or want to extend its life a bit, you can store it in the fridge for up to a week. Just bring slices to room temperature before serving for the best flavor and texture.
- Freezing (Glazed or Unglazed): This cake freezes beautifully.
- For an unglazed cake: Wrap the cooled cake tightly in plastic wrap, then in aluminum foil. It will keep for up to 3 months. Thaw overnight in the refrigerator, then glaze.
- For a glazed cake: Freeze individual slices or the whole glazed cake on a baking sheet until solid. Then wrap tightly in plastic wrap and foil. Thaw in the refrigerator.
The Key to Limes: A Quick Comparison
Choosing the right lime can certainly influence your cake’s flavor. While this recipe specifically calls for Key limes, it’s good to know the differences!
| Lime Type | Appearance | Flavor Profile | Juice Yield |
|---|---|---|---|
| Key Lime | Small, yellowish-green when ripe, thin skin | Aromatic, tart, distinct floral notes, slightly bitter finish | Low (needs many limes) |
| Persian Lime | Larger, bright green, thick skin | Less aromatic, more acidic, brighter, less complex | High (few limes needed) |
| Kaffir Lime | Bumpy, dark green skin | Bitter, very aromatic (mostly used for zest/leaves) | Very Low (not typically juiced) |
As you can see, the Key lime stands out for its unique flavor. So, while a Persian lime might work in a pinch, it won’t truly capture the essence of this delightful pound cake. Don’t skimp on the real deal; it truly makes all the difference!
Frequently Asked Questions
Can I use bottled Key lime juice?
While fresh is always best for that vibrant, genuine Key lime taste, you can certainly use bottled Key lime juice if fresh isn’t available. Just make sure it’s 100% Key lime juice and not a blend. Be aware that the flavor might not be as intense or as nuanced as with fresh limes.
What if my pound cake sinks in the middle?
There are various reasons why a sinking cake may occur! It could be over mixing the batter, opening the oven door prematurely (this causes a sudden decrease in temperature), or there could be an issue with the temperature of your oven. Ensure that your raising agents (baking powder) are not out of date, as well. Use an external thermometer to check your oven.
How do I know when the pound cake is done?
The best way is the skewer test! Insert a long wooden skewer or toothpick into the thickest part of the cake. If it comes out clean with no wet batter attached, your cake is ready. The top will also be golden brown and the edges will start to pull away from the pan.
Can I make this cake in a different pan?
Yes, you can! A 9×13 inch rectangular baking pan will work, but the baking time will be shorter, likely around 45-55 minutes. A loaf pan (9×5 inches) would also work, but you’d likely need two of them for this amount of batter, and baking time would be similar to the Bundt pan. Just keep an eye on it!
Why is my glaze too thin/thick?
The thickness of the glaze is all about the powdered sugar to liquid ratio. If it’s too thin, whisk in more powdered sugar, a tablespoon at a time, until it reaches your desired consistency. If it’s too thick, add a tiny bit more Key lime juice (or milk, if you prefer a less tart glaze) until it’s perfect for drizzling. It’s easy to adjust!
So, what are you waiting for? Are you ready to bake this gorgeous Key Lime Pound Cake and bring a little sunshine to your kitchen?
