Preheat oven to 350F/ 175C.
Cream together the butter, both sugars, and salt until smooth.
Beat in the eggs one at a time, finishing with the vanilla until combined.
Fold in the flour, oats and baking soda until almost combined, then fold in the chocolate chips and chocolate candies just until no flour remains.
Using an ice cream scoop or a spoon, scoop the cookies into about a two tablespoon sized ball onto a parchment lined sheet pan. Cover with plastic wrap and chill at least 2 hours.
When ready to bake, place the cookie dough balls about 2 inches apart onto a parchment lined sheet pan. Add a few more chocolate candies on top for a prettier cookie. Bake for about 10-12 minutes in the preheated oven, or until edges are golden brown. Rotate the pans halfway through baking and place a few candy eyeballs on top.
Cool for a few minutes on the sheet pan before carefully transferring to a cooling rack to cool completely.
*Don't skip on chilling the dough before baking.
*Adding the candy eyeballs midway through baking or soon as they're out of the oven helps them keep their shape.
*The dough freezes well for a few months. Be sure to scoop the cookies first and then chill the dough balls in a freezer safe zip-top bag. Thaw the frozen cookie dough on the sheet pan for a few minutes before baking.
*A little sprinkling of sea salt on the baked cookies is delicious.
