Preheat the oven to 350°F (175°C).
In a food processor, combine shredded coconut, almond flour, maple syrup, and melted coconut oil. Pulse until well combined.
Press the mixture into tart pans or muffin tins, making sure to evenly distribute the crust.
Bake for 10-12 minutes, or until lightly golden. Remove from oven and let cool.
In a saucepan, combine coconut milk, lime zest, lime juice, maple syrup, cornstarch, and vanilla extract.
Whisk continuously over medium heat until the mixture thickens, about 5-7 minutes.
Remove from heat and let it cool slightly.
Pour the coconut-lime filling into the cooled tart crusts.
Place the tarts in the refrigerator to set for at least 2 hours or until firm.
Once the tarts are set, remove them from the refrigerator.
Top each tart with slices of ripe mango and a sprinkle of lime zest.
Serve chilled and enjoy!
