Here's everything you'll need to create your amazing key lime cake :
The Star Players:
- 3 cups all-purpose flour (just your regular pantry flour will do perfectly!)
- 1 tablespoon baking powder (this helps our cake get nice and fluffy!)
- ½ teaspoon salt (just a pinch to make all the flavors pop)
- 1 cup unsalted butter, softened (that's 2 sticks - leave them out for about an hour to get soft)
- 2 cups granulated sugar (regular white sugar is perfect)
- 4 large eggs, room temperature (tip: put them in warm water for 5 minutes if you forgot to take them out early!)
- 1 cup whole milk (this makes our cake super moist and tender)
- ½ cup fresh key lime juice (about 12-15 of those cute little key limes)
- 2 tablespoons key lime zest (save this from your limes before juicing!)
- 1 teaspoon vanilla extract (our secret weapon for extra yumminess)
Pro Tip: Making a key lime cake? No worries if you can't find key limes! Regular limes will work just as beautifully in your cake - trust me, it'll still taste amazing! Just pop what you need on your shopping list and have fun baking. Remember, the most important ingredient is always your smile! 😊 🍰
the Key Lime Cream Cheese Frosting:
Here's what you'll need to whip up the most amazing key lime cream cheese frosting (warning: you might want to lick the spoon! 😋):
- 16 ounces cream cheese, softened (that's 2 regular blocks - let them get cozy on your counter for about an hour)
- 1 cup unsalted butter, softened (2 more sticks - they need to be super soft for ultra-creamy frosting!)
- 4 cups powdered sugar (also called confectioner's sugar - this makes it silky smooth)
- 2 tablespoons key lime juice (fresh is fantastic, but no stress if you need to use regular limes)
- 1 tablespoon key lime zest (this gives it that gorgeous speckled look and extra zing!)
- ¼ teaspoon salt (our tiny but mighty flavor booster)
Baker's Secret: Make sure your cream cheese and butter are really soft - but not melty! - for the fluffiest, smoothest frosting ever. Think room temperature hugs for your ingredients! 🤗

She always said, "Baking is just love made visible," and boy, was she right! Here are some of her time-tested secrets that make this cake absolutely unforgettable:
- Start with room-temperature ingredients - Grandma would set everything out while having her morning coffee. "Happy ingredients make happy cakes," she'd say with a wink!
- When zesting those key limes, she'd always do it over the butter and sugar mixture. "Those precious oils in the zest need somewhere cozy to land," she'd explain, and that extra step makes the lime flavor pop like sunshine!
- Her special mixing trick? She'd always count to 30 while creaming the butter and sugar - no shortcuts! "The fluffier the better," she'd sing, doing a little kitchen dance while waiting.
- For the frosting, she'd add just a tiny pinch of salt while humming her favorite tune. "It's like adding a sparkle to a smile," she'd say, and somehow, it made everything taste even better.
- The final grandma touch? She'd always let the cake layers hug each other overnight in the fridge. "They need time to get to know each other," she'd laugh, and you know what? The flavors really do become more magical the next day!
These might sound like simple tricks, but they're filled with the kind of love and care that only grandmas know how to give. And isn't that what makes any recipe truly special? 👵💝
FAQ
What is key lime cake recipe made of?
Key lime cake combines cake flour, fresh key lime juice and zest, butter, eggs, and sugar for a bright, tropical flavor. The tangy lime taste comes from fresh-squeezed key limes in both the batter and frosting. Most recipes include buttermilk or sour cream for moisture, and it's typically topped with lime-infused cream cheese frosting. The result is a light, tender cake with the perfect balance of sweet and citrus.
What is difference between lime and key lime?
Key limes are smaller and more yellow-green than regular (Persian) limes, about the size of a golf ball. They pack a stronger, more tart and floral flavor that gives desserts their distinctive tropical taste. Regular limes are larger, darker green, and less aromatic. While you can substitute regular limes, key limes deliver that authentic, more complex citrus punch many bakers prefer.
What is the secret ingredient in cake?
The secret to an amazing key lime cake is two-fold: using real key lime juice (not concentrate) and adding sour cream to the batter. The fresh key lime juice provides authentic flavor, while sour cream makes the cake incredibly moist and tender. Some bakers also swear by adding a splash of vanilla extract to enhance the lime's natural sweetness.
Does sour cream make cake moist?
Yes, sour cream is a game-changer for cake moisture. Its high fat content and acidity break down the gluten in flour, creating a more tender, moist crumb that stays fresh longer. For key lime cake specifically, sour cream adds richness while complementing the citrus tang. Even just 1 cup of sour cream can transform your cake from good to bakery-quality.
