Preheat oven to 350°F and line baking sheet with parchment paper.
In a large bowl, combine strawberry cake mix and baking powder.
In a smaller bowl, whisk together eggs, vegetable oil, and vanilla extract.
Pour wet ingredients into dry ingredients and stir until combined.
Fold in the white chocolate chips evenly into the dough.
Drop dough by rounded spoonfuls onto baking sheet, spaced 2 inches apart.
Bake for 10–12 minutes until edges are set, then cool 5 mins on sheet before transferring to wire rack.
Notes
Don’t overbake! Cookies should be soft in the center and will firm up as they cool. Can be topped with sprinkles or extra chocolate chips for decoration.
