Making Mango Strawberry Sunset Cupcakes is straightforward. Follow these simple steps to create these delightful treats:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a cupcake pan with cupcake liners.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
4. Add Eggs: Beat in the eggs one at a time, mixing well after each addition.
5. Incorporate Mango Puree: Add the mango puree and vanilla extract, mixing until well combined.
6. Combine Dry Ingredients: Gradually add the dry ingredient mixture to the wet ingredients, stirring until just combined. Be careful not to overmix.
7. Fold in Strawberries: Gently fold in the diced strawberries, ensuring an even distribution throughout the batter.
8. Fill Cupcake Liners: Spoon the batter into the prepared cupcake liners, filling each about two-thirds full.
9. Bake: Place in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool: Remove from the oven and allow the cupcakes to cool in the pan for about 10 minutes. Then transfer them to wire racks to cool completely.
