Preheat your oven to 350 degrees F and spray a 24-cup mini muffin tin with cooking spray.
Grab your sugar cookie dough and slice into 24 equal squares (just follow the perforated lines), then drop one square of cookie dough into each mini muffin tin cavity.
Bake for 14-16 minutes, then immediately take the handle of a spoon or spatula and press down in the center of each cookie to create a well.
At the same time, pour the shredded coconut onto a baking sheet and bake for 10 minutes, tossing halfway through, or until the coconut is lightly golden brown.
In a medium mixing bowl, combine coconut cream pudding mix with milk, ¾ cup heavy whipping cream, and sour cream. Whisk to dissolve any lumps, then set aside for 5 minutes to thicken.
Fold in ½ cup of the toasted coconut, then transfer the filling to a Ziploc bag, cut off one end, and evenly fill each cookie cup.
Combine the remaining heavy whipping cream with 1 tbsp powdered sugar and whip to form stiff peaks.
Transfer the whipped cream into a Ziploc bag, cut off one end, then squeeze a dollop on top of each filled cookie cup. Sprinkle with the remaining toasted coconut and enjoy!
