In a large mixing bowl, using a handheld mixer on low speed, combine the sugar cookie mix, all-purpose flour, unsalted butter, and egg mixture for 2 to 3 minutes or until thoroughly combined. The dough will be very thick.

Using a 1½ tablespoon (1½-inch) cookie scoop, scoop out a ball of dough and flatten it into a 3-inch disc in your hand. Place a Hershey’s Kiss into the center, carefully pulling the sides up to cover the candy, shaping it into a ball. Ensure the Hershey’s Kiss remains upright when placed into the mini muffin tin.

Place the dough balls into the muffin tin, keeping the Hershey’s Kiss upright, and bake for 10 to 12 minutes. Avoid browning the dough; it should be just cooked through.

Remove cookie cups from the oven and place one heart sprinkle, offset to the right from the center, on each cookie. Let cool in the mini muffin tin for at least 10 minutes before transferring to a wire rack to cool completely.
