Preheat oven to 350. Line a cookie sheet with parchment paper or a Silpat.
In a large bowl, combine the cake mix, pudding mix, vegetable oil, eggs and vanilla until a dough forms. Stir in ½ cup of the white chips.
Using a cookie scoop, drop dough by tablespoonfuls onto prepared cookie sheets 2 inches apart. Using the remaining ¼ cup white chips, press a few chips onto the tops of each cookie. If you're using the marshmallow creme pumpkins, don't worry about adding any extra chips to the top.
Bake for 8 to 10 minutes, or until cookies just start to lightly brown. The centers will still be very soft - that's okay! Cool for 2 minutes, then remove from cookie sheet to wire rack.
If desired, press a marshmallow creme pumpkin into the tops of your warm cookies.
