Preheat the oven to 325°F (163°C). Line baking sheets with parchment paper or a silicone baking mat.
Cream the shortening and granulated sugar in a mixing bowl with an electric mixer until light and fluffy, about 2–3 minutes.
Add the egg and vanilla extract and beat until incorporated and smooth.
In a separate bowl, whisk together the all-purpose flour, baking powder, and Kosher salt.
Gradually mix the dry ingredients into the wet mixture until just combined; do not overmix.
Fold in the mini chocolate chips (or 1/2 cup regular chips) and the sweetened coconut flakes until evenly distributed.
Drop tablespoon-sized portions of dough onto the prepared baking sheets, spacing them about 1½ inches apart.
Bake for 12–15 minutes, until the cookies are lightly browned at the edges and set in the center.
Allow the cookies to cool completely on the baking sheet, then transfer to a container for storage.
