Preheat the oven to 325 degrees F.

In a large mixing bowl, add cake mix, strawberry jello mix, softened butter, softened cream cheese, and egg. Use a hand mixer on medium speed to mix combined.

Use a measuring tablespoon to scoop the dough and roll it into balls. Place onto an ungreased baking sheet. Use the palm of your hand or the bottom of a flat glass to gently flatten the dough balls.

Bake in preheated oven for 12-14 minutes.

Use a spatula to carefully transfer the cookies to a wire cooling rack to cool completely.

To add the white chocolate drizzle to the cookies: Add white chocolate chips to a microwave-safe bowl and microwave on 50% power until melted, stirring every 30 seconds. Transfer melted white chocolate to a sandwich bag. Snip off a small corner of the bag and drizzle the white chocolate in a back-and-forth pattern over the top of each cookie.
