# Step-by-Step Instructions:
01 - Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
02 - In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside.
03 - In a large bowl, beat the softened butter and granulated sugar until light and fluffy, about 2 to 3 minutes.
04 - Add eggs one at a time, incorporating well after each addition. Stir in vanilla extract.
05 - Mix in the milk and mango purée until evenly combined.
06 - Gradually fold the dry ingredients into the wet mixture until just combined; avoid overmixing.
07 - Divide the batter evenly among the cupcake liners, filling each about three quarters full.
08 - Bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean. Allow to cool completely on a wire rack.
09 - Using a small knife or cupcake corer, remove a small center from each cooled cupcake and fill the cavity with one teaspoon of strawberry jam.
10 - Beat softened butter until creamy. Gradually add powdered sugar, mixing until smooth.
11 - Mix in vanilla extract and heavy cream (or milk) until the frosting is fluffy.
12 - Separate the frosting equally into three bowls. Leave one plain, fold mango purée into the second, and strawberry purée into the third.
13 - Spoon each colored frosting side-by-side into a large piping bag fitted with a star tip to create a sunset swirl effect.
14 - Pipe swirls of frosting onto each cupcake, forming a gradient reminiscent of a sunset.
15 - Optionally, adorn each cupcake with a fresh slice of strawberry or mango.
