Stir together the cake mix, oil and eggs.
Lightly stir in the sprinkles.
Drop by rounded teaspoonfuls onto a baking sheet covered with parchment paper or lightly sprayed with cooking oil. If you’re doing the right size, this should make 2 dozen cookies.
Bake in a preheated 350 degree oven for about 12 minutes or till done.
Let cool and then frost. I like to use about 1/2 cup of lightly softened store bought vanilla frosting. I put it in a zip top bag and cut the tip off, and pipe on the frosting.
Sprinkle the tops with the remaining sprinkles.
