I have been wanting to make monster cookies for a good month or more. In between Christmas, a new baby, and colds I wasn’t able to make them till yesterday.
I got this recipe from my sister-in-law before I was married. They are my husband and father-in-law’s favorite cookies, and are now one of my favorites.
The recipe makes such a large batch that I have always made a half-batch.
Monster Cookie Recipe (half-batch)
1 cup margarine softened (I use butter)
2 1/3 cups brown sugar
2 cups white granulated sugar
1/8 cup vanilla extract
3 1/3 cups peanut butter
4 teaspoons baking soda
9 cups oats
1 1/3 cups chocolate chips
1 1/3 cups M&M's
You will need a very large mixing bowl even for a half-batch. I use a 7.5 L bowl!! I mix all the ingredients except the chocolate chips and M&M's until they are well mixed. Then I stir in the chocolate chips and M&M’s.
Bake at 350°F for 8-10 minutes. I like my cookies soft in the center, and bake them for 9 minutes. Don’t let them bake till they're brown.
