Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.

In a large mixing bowl, combine the Funfetti sugar cookie mix, softened cream cheese, and the large egg. Mix until a soft dough forms.

If the dough is too sticky, refrigerate for 30–60 minutes to make shaping easier.

Pour the sanding sugar into a shallow bowl for coating.

Use a cookie scoop to portion the dough and roll into balls, then coat in sanding sugar.

Place the cookie balls on the baking sheet, spaced 1½ inches apart.

Bake for 8–12 minutes, until the edges are set but centers remain soft.

Cool for 3–5 minutes, then gently press a Hershey's Kiss into the center of each cookie.

Allow cookies to cool completely on a wire rack before serving.
