Toffee and M&M Monster Cookies

Toffee and M&M Monster Cookies (Adapted from the King Arthur Flour Cookie Companion)

4 1/2 cups old-fashioned rolled oats
1/2 cup all-purpose flour
2 teaspoons baking soda
1 teaspoon salt
3 large eggs
1 cup packed brown sugar
1 cup granulated sugar
1 teaspoon vanilla extract
1 teaspoon corn syrup
1/2 cup unsalted butter, melted
1 1/2 cups chunky peanut butter
3/4 cup chopped bittersweet chocolate or bittersweet chips (about 4 1/2 ounces)
3/4 cup toffee bits
3/4 cup dark chocolate M&Ms

Preheat oven to 350

In a medium bowl, whisk together oats, flour, baking soda and salt.

In a large bowl, mix together eggs, sugars, vanilla and corn syrup until combined. Stir in melted butter and peanut butter. Add dry ingredients and mix until thoroughly combined. Cover and set the dough aside to rest for 30 minutes.

Using a 1/4 cup measuring cup, drop the dough onto parchment lined baking sheets - slightly flatten each piece of dough. Bake until the cookies are lightly browned, about 10 to 12 minutes. Remove from the oven and transfer the cookies to a wire rack to cool.

Makes about 24 large cookies.
