Preheat the oven to 400°F (200°F) and a grease cake pan.
If you don't require a crust recipe, feel free to skip this step. Otherwise, cut the butter into smaller pieces and incorporate it with the flour and sugar until a crumbly texture is attained. Press this mixture into the cake pan to form the crust, then bake for approximately 10 minutes before setting it aside.
In a blender, mix the eggs, condensed milk, cream cheese, lime juice and zest.
Add 3/4 of the blueberries into the butter then pour on top of the baked crust.
Bake the cheesecake for 20-25 minutes, or until the center is set.
After cheesecake cools down, decorate with remaining fresh blueberries, and optional mint leaves.
Chill in the refrigerator for a minimum of 3-4 hours, slice and enjoy!
