Preheat your oven to 350°F (175°C) and line a cupcake tin with paper liners. Set aside.
In a large mixing bowl, whisk together the sifted flour and sugar until combined and light. This ensures even distribution of dry ingredients.
Add the melted butter, eggs, milk, lime juice, and vanilla extract to the mixing bowl. Whisk everything together until the batter is smooth, pale, and fragrant, about 2-3 minutes. You’ll notice the batter is silky and slightly frothy.
Fold in the chopped mango and strawberries gently, just until they’re evenly distributed. The fruit adds color and chewy texture, so don’t overmix.
Spoon the batter into the prepared cupcake liners, filling each about two-thirds full. This helps give the cupcakes a domed top and room to rise.
Bake in the preheated oven for 20-25 minutes, or until the tops are golden and a toothpick inserted into the center comes out clean. The cupcakes will be fragrant and slightly springy to the touch.
Remove the cupcakes from the oven and let them cool in the tin for about 5 minutes. Then transfer them to a wire rack to cool completely, allowing the crumb to set and making handling easier.
If desired, top the cooled cupcakes with a dusting of powdered sugar or a swirl of frosting for extra sweetness and presentation.
