Notes
Storage: Store chocolate cake mix cookies in an airtight container at room temperature for up to 5 days.
These cake mix cookies are endlessly customizable. Swap out half or all of the white chocolate chips for your favorite chocolate chips, toffee pieces, chopped nuts, sprinkles, or mini peanut butter cups.
For a holiday twist, substitute half of the pure vanilla extract for pure peppermint extract.
