- 1/2 cup unsalted butter (softened): Adds richness and moisture for a tender cupcake crumb.

- 2 large eggs: Bind all ingredients together and help achieve that light, fluffy texture.
- 1 teaspoon baking powder: Leavens the cupcakes making them rise just right.
- 1/2 teaspoon baking soda: Works alongside baking powder to keep the cupcakes tender.
- 1 3/4 cups flour: The main structure provider, creating the perfect cupcake base.

- 1/2 teaspoon salt: Balances the flavors and enhances sweetness.
- 4 cups powdered sugar: Sweetens and thickens the frosting while creating a smooth texture.
How to Make Key Lime Cupcakes Recipe
Step 1: Prepare the Batter
Begin by preheating your oven to 350°F (175°C) and lining your cupcake pan with paper liners. In a large bowl, cream together the softened butter, sugar, and brown sugar until light and fluffy. Then, add the eggs one at a time, beating well after each addition to incorporate air and create a smooth mixture that will keep your cupcakes light.
Step 2: Add Lime and Dry Ingredients
Mix in the key lime extract, key lime juice, and key lime zest for that unmistakable citrus pop. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, folding gently to avoid overmixing while still ensuring the batter is smooth and uniform.
Step 3: Bake the Cupcakes
Fill each cupcake liner about two-thirds full with batter. Bake in the preheated oven for approximately 16 minutes, or until a toothpick inserted into the center comes out clean. The cupcakes should spring back when gently pressed. Let them cool completely on a wire rack before frosting.
Step 4: Make the Cream Cheese Frosting
In a clean bowl, beat together the softened butter and cream cheese until creamy and well combined. Add the salt, key lime juice, and lime zest, mixing until incorporated. Gradually sift in the powdered sugar, folding gently and then beating on medium speed until the frosting is smooth, fluffy, and spreadable.
Step 5: Frost the Cupcakes
Once the cupcakes have cooled completely, generously frost each one with the lime cream cheese frosting. You can use a piping bag for a polished look or simply spread it on with a knife for a more rustic, homemade charm.
How to Serve Key Lime Cupcakes Recipe
Garnishes
Adding a garnish not only elevates the look of your cupcakes but also enhances the flavor experience. Consider topping each cupcake with a small piece of candied lime zest or a thin slice of fresh key lime for a natural, colorful accent. A sprinkle of toasted coconut or a few fresh mint leaves can also introduce an unexpected twist that complements the lime beautifully.
Side Dishes
Key Lime cupcakes are fabulous on their own, but pairing them with light, refreshing sides can turn your treat into a stunning mini celebration. Serve alongside a chilled glass of coconut water, a scoop of vanilla bean ice cream, or a platter of fresh berries to echo the citrus theme and add dimension to your dessert spread.
Creative Ways to Present
Make your Key Lime cupcakes utterly unforgettable by presenting them in creative ways. Arrange them on a tiered stand for an elegant display, or place them in bright, tropical-themed cupcake wrappers to highlight their sunny flavor. For a party, serve cupcakes in mini mason jars with a slice of lime on the rim for a playful, Instagram-worthy treat.
Make Ahead and Storage
Storing Leftovers
To keep your cupcakes fresh for the next day or two, store them in an airtight container in the refrigerator. The cream cheese frosting benefits from the chill and will retain its perfect texture while the cupcakes stay moist. Let them come to room temperature before serving to bring back their tenderness.
Freezing
You can freeze these cupcakes either frosted or unfrosted. For best results, freeze unfrosted cupcakes in a sealed container or freezer bag for up to 3 months. When you’re ready to enjoy, thaw completely at room temperature and then frost fresh for the best flavor and texture.
Reheating
If you prefer your cupcakes slightly warm, especially after refrigeration or freezing, gently reheat them in the microwave for 10 to 15 seconds on low power. Avoid overheating to prevent drying out. Remember to remove the frosting if reheating frozen unfrosted cupcakes before applying fresh frosting.
FAQs
Can I substitute regular lime juice for key lime juice in the recipe?
Absolutely! While key lime juice has a unique tartness and aromatic profile, regular lime juice works well as a substitute and still provides that bright citrus flavor essential for these cupcakes.
Is the key lime extract necessary?
The key lime extract is optional but highly recommended if you want to deepen the lime flavor without adding more liquid. It’s especially helpful if fresh key limes are hard to find.
Can I make the cupcakes gluten-free?
Yes! You can substitute the all-purpose flour with a gluten-free flour blend designed for baking. Just be sure the blend contains xanthan gum for structure, or add it separately.
How long do these cupcakes stay fresh?
When stored properly in the refrigerator, frosted cupcakes stay fresh for about 2 to 3 days. If you need longer storage, freezing is recommended.
Can I use regular limes if key limes are not available?
Yes, regular limes can be used without issue. The flavor will be slightly different but still delicious. Use the same amounts for juice and zest called for in the recipe.
