Preheat your oven to 350°F and line a baking sheet with parchment paper.
In a medium mixing bowl, stir together one 13.25 ounce box strawberry cake mix, 1 cup softened unsalted butter, and ½ cup vanilla yogurt until well combined into a dough.
Fold in 1 cup white chocolate chips.
Scoop the dough onto the prepared baking sheet using a standard cookie scoop (2 tablespoons).
Bake the cookies for 12 minutes, then let them cool slightly before transferring them to a rack.
Repeat with the remaining dough. Let the cookies cool completely, then enjoy.
