Make everybody's favorite party snack into a cookie! These No-Bake Muddy Buddy Cookies are simple to make – simply melt coating, stir in Chex, and allow to set. Great peanut butter/chocolate flavor.
In a large dutch oven over medium heat, combine marshmallows, butter, peanut butter, chocolate, vanilla, corn syrup, and brown sugar. Stir well until melted.
