THE BASICS: Nutter Butter cookies make the base for these mug cakes, but other filled cookies will work just as well (like Oreos).

ADD-INS: A scoop of peanut butter or Nutella adds a new flavor (and texture) to this mug cake.

Mini chocolate chips, white chocolate chips, chopped nuts, mashed bananas, or chopped dried fruit can be mixed in for extra flavor and crunch! Serve with a scoop of ice cream, whipped cream, caramel sauce, or chocolate sauce. So many options!
