Ingredients

How to make it

  • Preheat oven to 350° F and prepare a couple large cookie sheets with parchment paper.
  • Cream butter, peanut butter, and sugars.
  • Beat in eggs and vanilla.
  • Beat in corn syrup and baking soda, then oatmeal and M&M's.
  • Drop onto cookie sheets with an ice cream scoop and flatten slightly.
  • Bake at 350°F for about 12 minutes or until done. Do not overbake!
  • Remove from oven when slightly golden. Let cool on the sheets for a few minutes until they have firmed up enough to remove to wire racks.
  • Freezing: Roll unbaked dough into balls and freeze on a cookie sheet. When completely frozen, remove dough balls to freezer bags. These will stay good for several months, depending on how sturdy your bags are. Bake straight from the freezer; they will only need an extra few minutes in the oven.

    This is the recipe i have been looking for,ty so much. I always wanted the one with the corn syrup in it. I make these for my autistic son by using Splenda brown sugar and Splenda with sugar free m&m's so he can enjoy some of the thing I did as a child. My recipe cuts the sugar content enough so he can have 1 cookie a day after school. Ty ty ty again!!!
