It is not a mistake-- there is no flour nor salt used in this recipe.
You will need a HUGE mixing bowl, and plenty of muscle to mix these up.
Start at the top of the following ingredient list and mix together, stopping to mix after each addition. (Because I have a large-bowled and more powerful model of Kitchen Aid stand mixer, I can get away with dumping in everything from this first list and mix it together with that. Then, I dump all of the mixed dough into a really large mixing bowl, add the final three ingredients and mix by hand.)
1 pound butter, room temperature
3 lbs. natural peanut butter (crunchy or creamy)
4 cups white granulated sugar
2 lb. bag of brown sugar
12 eggs, slightly beaten ahead of time
1/4 cup vanilla
2 tablespoons light corn syrup (I like Karo)
8 teaspoons baking soda
18 cups ROLLED OATS (quick-cooking, or old fashioned)
1 of 12 oz. package semi-sweet chocolate chips
1 lb. bag of plain M&M's (optional)
Pre-heat oven to 350-degrees
Take scoops of dough and form into 2" balls, place on cookie sheet that's been lined with parchment paper or aluminum foil. Air-bake pans work well because these cookies like to darken on the bottom before their tops and centers are done. Since oven temperatures vary, baking time could be between 12 and 14 minutes (or ??). Let cookies cool on pans for a while.
Here!, sit a while and have a cookie.........................
