1. Melt the marshmallows and butter in a microwave safe bowl (6 cups mini marshmallows, 4 tablespoons of butter).
2. Stir in 6 cups of Rice Krispies.
3. Put a bit of oil or Pam or butter on your fingers to prevent stickiness and then using a teaspoon, scoop a bit of the treat mixture and roll into a small ball. Place on waxed or parchment paper. Think small because these get huge when they are coated.
4. Pop the balls into the freezer for about 5 minutes so that they harden.
5. In the meantime, melt white or semi-sweet chocolate chips in the microwave for 30 seconds intervals, stirring in between each 30 seconds, until melted.
