This cozy Halloween monster cookie bark is the perfect replica of a beloved candy shop’s magic—a chewy, peanut-buttery cookie base topped with smooth chocolate, crunchy pretzels, candy corn, M&Ms, and candy eyeballs. It’s quick, easy, and guaranteed to be a crowd-pleaser.
For the best texture, use old-fashioned rolled oats, not quick oats. Avoid overbaking the cookie base—it should look slightly underdone when removed from the oven. The bark can be stored in an airtight container at room temperature for up to 5 days, or frozen for up to 3 months. The flavors improve after a day or two.
