Melt Butter and Marshmallows: In a large pot over low heat, combine the butter and marshmallows. Stir continuously until the marshmallows are melted and smooth.
-
Add Food Coloring: Once melted, divide the marshmallow mixture into two bowls. In one bowl, add a few drops of red food coloring and mix until the color is uniform. In the second bowl, if using, add a drop of green food coloring for added flair.
-
Combine Rice Krispies: Pour the entire 6 cups of Rice Krispies into the bowl with the red marshmallow mixture. Stir until all the cereal is coated evenly with the marshmallow.

Shape the Brains: While the mixture is still warm but manageable, take small handfuls and shape them into brain-like halves. Slightly flatten the top and bottom to give a more realistic brain appearance.
-
Chill and Set: Place the shaped brains onto the prepared wax paper. Allow them to cool for about 30 minutes, or until firm.
-
