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!

Tips for Microwave Mug Cakes

  • Save food processor clean-up by crushing nutter butter cookies in a zippered bag with a rolling pin.

  • Store leftover mug cakes by covering them with plastic wrap and keeping them in the refrigerator.
