Monster cookies are known for two things: incorporating just about every mix-in you can think of into the batter and their signature enormous size.

These monster cookies begin with a standard cookie dough before the real fun begins. Rolled oats are incorporated into the batter to give it additional flavor and texture. Chocolate chunks, chopped peanuts, and colorful candy-coated chocolate pieces are then folded into the mix. This is where you can get creative with your favorite mix-ins to create your own signature monster cookie. As long as the mix-ins total three cups, feel free to get creative. Try using a variety of chips, nuts, dried fruits, and candy in various sizes, shapes, and colors.

To make the cookies large and all uniform in size, use a 1/2 cup measure to scoop the cookie dough. They will spread a bit in the oven, so be sure to leave ample space between each mound of dough on the baking sheet. The result will be a giant cookie that will practically fill up an entire plate and delight cookie lovers of all ages.

Tip

  • Brown sugar is measured differently than regular granulated sugar. Recipes call for brown sugar to be "firmly packed" in order to ensure a consistent measurement. Packing brown sugar presses out the pockets of air between the sticky granules. Scoop the brown sugar into the measuring cup. Press down the brown sugar until it is tight and compact. Repeat the scooping and pressing as needed until the measuring cup is full. The top of the brown sugar should be flush with the top of the measuring cup.
