Let me ask you something: Have you ever tasted sunshine in cake form? No? Then you, my friend, have clearly never had a slice of Key Lime Pound Cake. And if you have—well, you already know we’re about to dive into something glorious (no, not literally—no cake diving allowed).
Today, I’m handing you my go-to recipe for a Key Lime Pound Cake that’s buttery, dense, zippy, and just the right amount of sweet. Think pound cake meets citrus vacation, and yeah… it’s as magical as it sounds.
Why Key Lime Pound Cake Deserves a Spot in Your Baking Hall of Fame
Let’s be real—pound cakes have a reputation. Heavy, dense, and sometimes… a little boring. But throw in key lime juice and zest? Boom. Instant upgrade. This cake goes from “meh” to “where-have-you-been-all-my-life?” in one bite.
Here’s why you need this cake in your life:
- It’s tangy, buttery, and sweet—basically a triple threat.
- It travels well, so picnic? Potluck? Road trip? Yup, it’s coming with.
- No complicated steps—if you can cream butter and sugar, you can make this.
- The glaze is next level. Seriously, don’t skip the glaze.
🧈 Ingredients You’ll Need for Key Lime Pound Cake
Before we get baking, let’s run through the ingredient list. FYI: Don’t try to substitute regular limes for key limes unless you’re desperate. The flavor just isn’t the same. I mean, would you put ketchup on spaghetti? Exactly.
For the Cake:
- 1 cup (2 sticks) unsalted butter, softened (but not melting into a puddle)
- 2 ½ cups granulated sugar
- 5 large eggs
- 3 cups all-purpose flour (spooned and leveled—not scooped like you’re shoveling gravel)
- ½ teaspoon baking powder
- ½ teaspoon salt
- ¾ cup whole milk
- ⅓ cup key lime juice (fresh is fab, bottled works in a pinch)
- 1 tablespoon key lime zest (don’t skip it—it’s the flavor MVP)
- 1 teaspoon vanilla extract
For the Glaze:
- 1 cup powdered sugar
- 2–3 tablespoons key lime juice
- Optional: extra zest for flair (a.k.a. look how fancy I am)
🍰 Step-by-Step: From Batter to Beautiful
Alright, tie on your apron (or your “Baking Is My Therapy” t-shirt—whatever works), and let’s get into it.
Step 1: Preheat and Prep
Set your oven to 325°F (165°C). Grease and flour a bundt pan or a loaf pan. No, you cannot “eyeball” the greasing. Don’t make me say “I told you so” when the cake sticks.
Step 2: Cream Like You Mean It
In a large bowl, beat the butter and sugar until it’s light, fluffy, and dangerously delicious-looking. This step takes about 4–5 minutes with a stand mixer. If your arm’s cramping from a hand mixer—congrats, you’re doing it right.
Step 3: Eggs Go In
Add the eggs one at a time, beating well after each one. You want a smooth, silky batter—not a lumpy scrambled egg situation.
Step 4: Mix the Dry Gang
In a separate bowl, whisk together the flour, baking powder, and salt. Set aside. Admire your prep skills. You’re basically a food network star now.
Step 5: Wet Ingredients Join the Party
In another small bowl, combine the milk, key lime juice, zest, and vanilla. It’ll look slightly weird and curdled. That’s normal. Don’t panic.
Step 6: Alternate Like a Pro
Add the dry ingredients to the butter mixture in three additions, alternating with the limey milk mix. Start and end with flour. You know the drill: mix just until combined. Over-mixing = sad, dense cake. And not in a good way.
Step 7: Bake It, Baby
Pour the batter into your prepared pan and smooth the top. Bake for 65–75 minutes, or until a toothpick comes out clean. If the top browns too fast, tent it with foil halfway through.
⏳ Cool Down, Then Glaze Up
Once your cake is out of the oven, let it cool in the pan for about 10–15 minutes, then gently turn it out onto a wire rack. Don’t rush this part. Hot cake = fragile cake.
For the Glaze:
Mix the powdered sugar with key lime juice until it’s smooth and pourable. Not too thick, not too runny. Like Goldilocks, but with icing. Drizzle it over the completely cooled cake and let it drip all dramatic-like down the sides.
Optional flex: Sprinkle some lime zest on top for that “I bake AND style” energy.
🍴 Serving Suggestions (a.k.a. Make It Fancy)
You could eat this cake plain. But why stop there when you can elevate it?
Here are a few ways to dress it up:
- With whipped cream (not from a can—you’re better than that)
- Alongside fresh berries—raspberries and key lime = 💯
- Toasted coconut sprinkled on top for a tropical vibe
- Warmed slightly and served with vanilla ice cream—IYKYK
📝 Pro Tips: Because You Deserve the Best
Want to avoid a cake catastrophe? Keep these tips in mind:
- Room temp ingredients = smooth batter. Cold eggs and butter are party crashers.
- Don’t skip the zest. I know I said this before, but seriously—zest is flavor gold.
- Use a light-colored pan. Dark pans cook faster and may over-brown the cake.
- Don’t over-bake. Dry pound cake is a crime.
🤔 FAQs About Key Lime Pound Cake
Q: Can I use regular limes?
A: You can… but should you? Nah. Key limes are smaller, tarter, and way more aromatic. If you absolutely must use regular limes, at least toss in a little lemon juice to fake that signature zing.
Q: Can I freeze this cake?
A: Heck yes! Wrap slices tightly and freeze for up to 2 months. Thaw overnight in the fridge or warm slightly in the microwave. Boom—cake on demand.
Q: What if I don’t have a bundt pan?
A: Use two loaf pans instead. Same delicious result, just a different shape. No bundt shame here. 🙂
👩🍳 Why I’m Obsessed with This Cake (And You Might Be Too)
I’ll be honest—this recipe wasn’t love at first bite. I used to be a chocolate-only dessert person. Like, if it didn’t involve cocoa, I wasn’t interested. Then one day, my neighbor brought over a key lime pound cake after I helped jump her car (true story). I took one bite and boom—converted.
There’s just something about that bright citrus tang cutting through all the buttery richness that makes this cake so addictive. It’s rich but refreshing, indulgent yet light. The balance is chef’s kiss.
