Monster Cookies (flourless)

My friend's mom used to make these and put them in the deep freeze in their garage. For some reason, I really liked their garage! Maybe I should have called them Disappearing Cookies! I'm telling you, they are a big hit with kids! Better yet, there's no flour in them--just oats!

6 small eggs
1 lb. brown sugar
2 cups white sugar
2 tsp. vanilla
2 tsp. corn syrup
½ lb. butter
1-1/2 lb. peanut butter
4 tsp. baking soda
9 cups oatmeal (3 minute kind is good, instant is okay as well)
½ lb. M & Ms
½ lb. chocolate chips

Mix in order given. Drop by tablespoons or ice cream scoop on baking sheet. Bake at 350 degrees for 12-15 minutes.
