Optional Mix-in’s: Chocolate chips, M&M’s, Rolo's, etc.
Preheat oven to 350°F. Line a baking sheet with a silicone mat or parchment paper and set aside.
Combine the cake mix, oil and eggs in a large bowl. Stir together until combined. If you have the time, refrigerate the dough for 15-20 minutes (it will make it a little easier to work with, since it is sticky).
Using a medium scoop or spoon, scoop the dough onto the prepared baking mat. Bake for 9-11 minutes, or until the cookies are set. You don’t want them to brown. Allow to cool on the pan for a couple minutes and then transfer to a cooling rack.
To dip in chocolate: Once cooled, melt the chocolate and then dip half the cookie into the chocolate. Lay cookies onto a wax paper and add sprinkles if desired.
