Preheat your oven to 350°F (175°C). Lightly spray a mini cupcake pan with cooking spray to prevent sticking.
In a large bowl, gently beat together the sugar cookie mix, melted butter, all-purpose flour, egg, and a few drops of pink or red food coloring until everything is just combined and you have a lovely, soft pink dough. Adjust the food coloring until you reach your desired shade.
Scoop out about 1 tablespoon of the cookie dough and gently flatten it in the palm of your hand to create a small, circular disk.
Place one unwrapped Hershey's Hug in the center of the flattened dough. Carefully wrap the dough around the chocolate, sealing it completely to form a neat little ball. Don't worry if there are tiny cracks; just smooth them out with your fingers.
Place each chocolate-filled dough ball upright into a cavity of your prepared mini muffin pan. Continue this process until all your cookie dough is used.
Bake for 10-12 minutes, or until the edges of the cookie cups look set and are lightly golden.
Once you take them out of the oven, immediately press your decorative sprinkles gently onto the warm tops of the cookie cups. The warmth will help them stick perfectly.
Allow the cookie cups to cool in the pan for about 15 minutes before carefully removing them. This ensures they hold their shape beautifully. Serve and enjoy your sweet, homemade treats!
