In a large mixing bowl, combine the strawberry cake mix, melted butter, and one egg. Mix until smooth, about 2-3 minutes.

Add the softened cream cheese to the dough mixture and mix until fully incorporated, about 2-3 minutes.

Cover the bowl and refrigerate the dough for at least 1 hour to prevent spreading.

Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.

Scoop tablespoon-sized portions of dough and roll into balls. Place on the prepared sheets.

Optionally, roll each ball in powdered or pink granulated sugar.

Bake for 8-10 minutes. The edges should be set while centers remain soft.

Remove from the oven and let rest for 1-2 minutes before pressing a chocolate kiss into each cookie.

Transfer cookies to a wire rack to cool completely.
