Ingredients
- 1 cup all-purpose flour
This is the base of the cupcakes, providing structure and texture. All-purpose flour helps create a light and fluffy cupcake, allowing it to rise nicely during baking. - 1/2 cup unsalted butter, softened
Butter contributes to the moistness and richness of the cupcakes. It also helps achieve a tender crumb, and the flavor complements the tropical ingredients perfectly. - 1 cup granulated sugar
Sugar not only sweetens the cupcakes but also aids in browning during baking. It enhances the overall flavor and moisture of the finished product. - 2 large eggs
Eggs are essential for binding the ingredients together and providing structure. They also add moisture and richness to the cupcakes, contributing to their soft texture. - 1/2 cup mango puree
Mango puree infuses the cupcakes with sweet tropical flavor and moisture. It gives a unique taste that pairs beautifully with the key lime. - 1 tbsp key lime zest
The zest adds a punch of citrus flavor without the acidity of the juice. It enhances the overall taste, making the cupcakes refreshing and aromatic. - 1/4 cup key lime juice
This adds tartness to the cupcakes, balancing the sweetness of the mango. The acidity also helps to tenderize the batter, resulting in a more delicate crumb. - 1 tsp baking powder
Baking powder is a leavening agent that helps the cupcakes rise and become light and airy. It's crucial for achieving the perfect height during baking. - 1/4 tsp salt
Salt enhances the flavor of the cupcakes, helping to balance the sweetness. It also improves the overall taste complexity. - 1 cup powdered sugar (for glaze)
Powdered sugar is used for the glaze, providing sweetness and a smooth texture. It makes the finishing touch visually appealing and complements the flavors. - 2 tbsp key lime juice (for glaze)
This gives the glaze its tartness, making it a refreshing addition on top of the sweet cupcakes. It helps to balance out the sweetness of the powdered sugar.
Directions & Preparation
Step 1: Preheat the oven to 350°F (175°C) and line a muffin tin with paper liners.
Preheating the oven ensures that the cupcakes begin to bake immediately when placed inside, helping them rise evenly. Lining the muffin tin prevents the cupcakes from sticking, making it easier to remove them once baked.
Step 2: In a large mixing bowl, cream together softened butter and granulated sugar until light and fluffy.
Creaming the butter and sugar is a crucial step that incorporates air into the mixture, resulting in a lighter texture. This aeration helps the cupcakes rise and gives them a delightful softness.
Step 3: Add the eggs one at a time, mixing well after each addition. Then, stir in the mango puree, key lime zest, and key lime juice.
Incorporating the eggs gradually allows for a more stable emulsion. The addition of mango and lime adds flavor and moisture, enriching the batter while ensuring everything is well-combined.
Step 4: In a separate bowl, whisk together the flour, baking powder, and salt.
Whisking the dry ingredients separately ensures that the baking powder is evenly distributed throughout the flour. This helps prevent any unexpected pockets of leavening agent that could affect the cupcakes' rise.
Step 5: Gradually add the dry ingredients to the wet mixture, mixing gently until just combined.
Overmixing can lead to dense cupcakes, so it’s important to mix until just combined. This ensures a tender crumb, allowing the flavors of mango and key lime to shine through.
Step 6: Fill each cupcake liner about two-thirds full with batter.
Filling the liners to the right level allows for adequate rising while preventing overflow. This results in nicely shaped cupcakes with a domed top.
Step 7: Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
This step is crucial for ensuring the cupcakes are cooked through without being dry. Keeping a close eye on the baking time helps you achieve the perfect texture.
Step 8: Let the cupcakes cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Cooling in the pan allows the cupcakes to set slightly, but transferring them to a wire rack helps prevent sogginess. Proper cooling is essential for the glaze to adhere better.
Step 9: For the glaze, whisk together powdered sugar and key lime juice until smooth and drizzle-ready.
Mixing the glaze to the right consistency will ensure it evenly coats the cupcakes without being too runny. This step adds a delightful finish to the already flavorful treats.
Step 10: Drizzle the glaze over the cooled cupcakes and let it set before serving.
Allowing the glaze to set gives it a glossy, attractive finish and enhances the overall presentation of the cupcakes. Patience here pays off in both taste and appearance.

Mango Magic: The Perfect Puree
Using fresh or canned mango puree can significantly enhance the flavor of your cupcakes. If opting for fresh, make sure to choose ripe mangoes for maximum sweetness and flavor. This tropical ingredient not only adds moisture but also contributes to the overall lightness of the cupcakes, ensuring a delightful surprise in every bite.
Zesty Key Lime: A Burst of Flavor
Key lime zest and juice provide an unmistakably vibrant citrus flavor that perfectly complements the sweetness of mango. While the zest amplifies the aroma and taste, the juice adds necessary acidity, preventing the cupcake from being overly sweet. Together, they create a harmonious balance, making each cupcake a refreshing treat.
The Glaze: Adding That Finishing Touch
Topping your mango key lime cupcakes with a delightful glaze is an essential step that amplifies their flavor profile. The glaze not only enriches the sweetness but also adds a tangy finish that contrasts beautifully with the cake. When drizzled over a still-warm cupcake, it creates a tempting visual that invites everyone to indulge.

Keep an eye on the baking time and start checking for doneness a couple of minutes early. The cupcakes are ready when a toothpick comes out clean or with a few moist crumbs.
