These Monster Cookies are thick 'n chewy, soft, and filled with the goodness of whole oats, peanut butter, chocolate, and M&M's. Every major cookie lovers' dream come true.
In a large mixing bowl, combine eggs and sugar. Mix well to combine.
Add salt, vanilla, peanut butter, and butter. Mix to incorporate.
Stir in the baking soda and oats. Gently fold in M&M's and chocolate chips.
Form a ball and wrap tightly with plastic wrap. Chill at least 1 hour or overnight.
Preheat oven to 350F and live baking sheets with parchment or baking mats.
Form dough balls about 1 TB in size, and place 2 inches apart on lined baking sheets. Flatten cookies somewhat, as they tend not to spread much.
Bake 7-8 minutes. Take care not to over-bake. Cookies will set further upon cooling.
Notes
Different brands of peanut butter contain varying amounts of sugar. If you use a less-sweet peanut butter, you'll need to add more sugar to the dough. I usually use Skippy Creamy Peanut Butter for best results.
Be sure to use regular peanut butter that is already creamy and pre-stirred. Some natural peanut butters that have oil separation may not work as well.
Be careful not to over-bake your cookies. They may seem slightly underdone at the 7-8 minute mark, but they will continue to set as they cool to a soft and chewy texture.
Feel free to customize your monster cookies with additional mix-ins like chopped roasted nuts, white chocolate chips, or milk chocolate chips.
If desired, press on additional M&M"s on top immediately after cookies come out of oven.
These cookies are perfect for making ahead of time. The raw dough can be stored airtight in the refrigerator for up to 5 days or frozen airtight for up to a month.
