Preheat the oven to 350°F. Line a 12-cup muffin pan with paper cupcake liners.
In a medium bowl whisk together the flour, baking powder, baking soda, and salt until well combined; set aside.
In a large mixing bowl beat 1/2 cup softened butter and the granulated sugar with a hand mixer for 2 to 3 minutes until pale and fluffy.
Add the eggs one at a time, beating well after each addition, then mix in the vanilla bean paste.
Add the 1/2 cup mango puree, Greek yogurt, and mango juice to the butter mixture and mix on low speed until smooth and combined.
Add the dry ingredients to the wet ingredients and mix on low speed just until no streaks of flour remain; do not overmix.
Use an ice cream scoop or large spoon to divide the batter evenly among the liners, filling each about two-thirds full, and smooth the tops lightly.
Bake for 16 to 18 minutes, or until the tops are lightly golden and a toothpick inserted in the center of a cupcake comes out clean.
Remove the pan from the oven and let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely, at least 30 minutes.
While the cupcakes bake, place the strawberry preserves and cornstarch in a small saucepan and stir to combine.
Cook the strawberry mixture over medium heat, stirring constantly, until it bubbles and thickens, about 2 minutes, then remove from the heat and let it cool completely.
Once the cupcakes are completely cool, use an apple corer or small paring knife to cut a 1 inch deep cone from the center of each cupcake and reserve the cake pieces as lids.
Spoon about 1 teaspoon of the cooled strawberry filling into the center of each cupcake, then replace the reserved cake pieces to cover the filling.
In a large mixing bowl beat 1 cup softened butter with a hand mixer for about 2 minutes until creamy and smooth.
Add the powdered sugar 1 cup at a time, mixing on low speed after each addition, then add the heavy cream and beat on medium speed until the frosting is light, fluffy, and spreadable.
Divide the frosting into three portions: leave one portion plain, mix the mango puree into the second portion, and mix the strawberry puree into the third portion.
Tint the mango frosting portion with a small amount of yellow gel food coloring and the strawberry frosting portion with a small amount of pink gel food coloring, mixing each until the color is even.
Fit a large piping bag with a star or round tip and add spoonfuls of the three frostings side by side in the bag to create a swirled sunset effect.
Pipe tall swirls of frosting onto each filled cupcake, turning the cupcake as you pipe to form a spiral.
Serve the cupcakes at room temperature and store any leftovers in an airtight container.
