Serving: 12 | Prep Time: 20 minutes | Cooking Time: 18 minutes
Ingredients
- Graham cracker crumbs – 1 cup
- Granulated sugar – 1 ¾ cups
- Unsalted butter, melted – 4 tablespoons
- All-purpose flour – 1 ½ cups
- Baking powder – 1 ½ teaspoons
- Salt – ¼ teaspoon
- Vegetable oil – ½ cup
- Eggs – 4
- Key lime juice – ⅔ cup
- Buttermilk – ½ cup
- Sweetened condensed milk – 1 can (14 oz)
- Cream of tartar – ¼ teaspoon
- Vanilla extract – 1 teaspoon
Instructions
- Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners.
- Make the crust: In a small bowl, mix 1 cup graham cracker crumbs, ¼ cup granulated sugar, and 4 tablespoons melted butter until combined.
- Press 1 tablespoon of crust mixture into the bottom of each liner. Bake for 5 minutes, then cool.
- Make the cake: In a medium bowl, whisk 1 ½ cups flour, 1 cup sugar, 1 ½ tsp baking powder, and ¼ tsp salt.
- In a large bowl, whisk ½ cup vegetable oil, 2 egg yolks (reserve whites), ⅓ cup key lime juice, and ½ cup buttermilk until smooth.
- Add dry ingredients to wet and mix until just combined. Tip: Don't overmix or cupcakes will be tough.
- Divide batter among liners, filling each ¾ full. Bake 15-18 minutes until a toothpick comes out clean. Cool completely.
- Make the curd: In a heatproof bowl, whisk 2 egg yolks, 1 can sweetened condensed milk, and ⅓ cup key lime juice until smooth.
- Set bowl over simmering water and cook, stirring constantly, until thickened (about 8 minutes). It should coat the back of a spoon. Tip: Keep heat low to avoid scrambling eggs.
- Remove from heat and cool to room temperature. The curd will thicken further as it cools.
- Make the meringue: In a clean bowl, beat 4 reserved egg whites with ¼ tsp cream of tartar until foamy. Gradually add ½ cup sugar, beating until stiff peaks form. Add 1 tsp vanilla and beat briefly. Tip: Ensure bowl is grease-free for proper volume.
- Assemble: Using a small knife, cut a cone from the center of each cupcake. Fill the hole with key lime curd.
- Pipe or spoon meringue over each cupcake, covering the top completely. Use a kitchen torch to toast the meringue until golden. Alternatively, broil for 1-2 minutes, watching closely.
- Chill cupcakes for at least 1 hour before serving. This sets the curd and makes the flavors meld.
Velvety meringue meets tangy lime curd in every bite. Serve chilled for a refreshing dessert that captures summer in a cupcake.

Key Lime Macaron Cupcakes
Get ready for a tangy twist on two classics. These Key Lime Macaron Cupcakes combine airy almond shells with a zesty filling. Perfect for a bright dessert.
Serving: 24 | Prep Time: 30 minutes | Cooking Time: 18 minutes
Ingredients
- Almond flour – 1 cup
- Powdered sugar – 1 ¾ cups
- Egg whites – 3 large
- Granulated sugar – ¼ cup
- Cream of tartar – ¼ tsp
- Unsalted butter – ½ cup
- Powdered sugar (for filling) – 1 ½ cups
- Key lime juice – 3 tbsp
- Key lime zest – 1 tbsp
- Vanilla extract – ½ tsp
Instructions
- Sift almond flour and 1 ¾ cups powdered sugar together to remove lumps. (Tip: Sift twice for a smoother shell.)
- In a stand mixer bowl, combine egg whites and cream of tartar. Whip on medium speed until foamy.
- Gradually add granulated sugar, then increase speed to high. Whip to stiff, glossy peaks. (Tip: Use room temperature egg whites for better volume.)
- Fold the dry mixture into the meringue with a spatula. Stop when the batter flows like lava and forms a ribbon. (Tip: Underfolding leads to hollow shells; overfolding makes them flat.)
- Transfer batter to a piping bag with a round tip. Pipe 1.5-inch circles onto parchment-lined baking sheets, spacing 2 inches apart.
- Firmly tap the baking sheet on the counter 5 times to release air bubbles. Let rest at room temperature for 30 minutes until a skin forms on the surface.
- Preheat oven to 300°F. Bake for 15–18 minutes, rotating halfway. Shells are done when they lift cleanly from the parchment and have developed feet.
- Let shells cool completely on the sheet before removing.
- Make the filling: In a bowl, beat softened butter until creamy. Add 1 ½ cups powdered sugar, key lime juice, zest, and vanilla. Beat until smooth and fluffy.
- Pair shells by size. Pipe or spoon filling onto the flat side of one shell, then top with the other. Gently twist to seal.
- Refrigerate assembled macarons in an airtight container for at least 24 hours to mature. This enhances texture and flavor.
Layers of delicate almond and sharp key lime melt together in every bite. The creamy filling balances the crisp shell perfectly. Serve chilled for the best experience.
