Chewy Monster Cookies have an oats cookie dough base loaded with M&Ms, chocolate chips, and Nutella for a rich, chocolatey flavor. Perfect for a snack or paired with vanilla ice cream.
In a large bowl, beat butter and sugars until creamy. Add egg, vanilla, and Nutella. Mix until combined.
Whisk dry ingredients in a separate bowl. Gradually add to wet ingredients, mixing on low until combined.
Fold in M&Ms and chocolate chips. Chill the dough for 30 minutes to 1 hour until firm.
Preheat oven to 350°F. Roll dough into 2-inch balls and place on a lined baking sheet. Bake for 10-12 minutes.
Let cookies cool on the pan for 5-10 minutes, then transfer to a wire rack to cool completely.
