What makes a monster cookie a monster cookie? Is it the size? The M & M's? If it's the latter, then these are not monster cookies. I ended up buying some candies that were not technically M & M's, and my kids think the candies are gross, so we had to make our monster cookies without. They're still very good cookies, and despite all the sugar I feel like they're a bit wholesome, with peanut butter and oatmeal as the main ingredients.
They mix up in one bowl, too! I found the recipe on , and tweaked it a bit according to what I had on hand and what some people said in the comments. I mixed these ingredients together in a big bowl, in this order, mi after each addition: 1 egg, beaten; 1/2 cup packed brown sugar; 1/3 cup white sugar; 1/2 teaspoon vanilla; 1/2 teaspoon corn syrup; 3/4 teaspoon baking soda; 3 tablespoons softened butter; 1/2 cup peanut butter; 1 cup rolled oats; 1/2 cup quick cooking oats; 1/2 cup chocolate chips. I mixed well, then used a 2-tablespoon scoop to making heaping scoops of dough on a cookie sheet.
I put only 5 cookies on a baking sheet, spacing them out to allow them to spread. The instructions said "ungreased baking sheet," but I found that they stick, so for the next two batches I used a parchment-lined baking sheet. I baked at 350F for 12 to 15 minutes, then allowed to cool before removing them from the baking sheet. (If you try to move them early, they'll fall apart.)
These cookies are irresistable. They're chewy and sweet, and I had to hide them from the children.
