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.
If desired, melt 1/2 cup chocolate and then dip half the cookie into the chocolate. Lay cookies onto a wax paper and add sprinkles if desired.
Variation: You may also mix in a 1/2 cup white chocolate chips if you’d prefer. For a sweet touch, roll the dough balls into granulated sugar before baking.Storage: To store, simply add to an airtight container or bag and keep at room temp for up to 1 week. You can even freeze the cookies if you'd like. Just let them cool completely, then place in a freezer bag and freeze for up to 2 months.
