Creating Mango Strawberry Sunset Cupcakes is a straightforward process if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a cupcake tin with paper liners.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In a large bowl, beat the softened butter and granulated sugar until light and fluffy.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
5. Incorporate Mango: Gradually mix in the mango puree until well combined.
6. Combine Mixtures: Alternately add the dry ingredients and milk to the butter mixture, starting and ending with the dry ingredients. Mix until just combined.
7. Fill Cupcake Liners: Divide the batter evenly among the prepared cupcake liners, filling each about two-thirds full.
8. Bake: Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
9. Cool: Remove the cupcakes from the oven and allow them to cool in the pan for 10 minutes. Transfer to a wire rack to cool completely.
10. Prepare Frosting: In a mixing bowl, beat the softened butter until creamy. Gradually add powdered sugar, heavy cream, and vanilla extract, mixing until smooth. Fold in the mango puree.
