Double Layer Rice Krispies

Melt:  1 stick margarine
Add:  1 - 16 oz. pkg. mini marshmallows
Add:  7 c. rice krispies

Pat into 9x13 (I use a larger pan so the layers aren't so thick) pan.  Melt 1 bag of milk chocolate chips and spread on rice krispies.  Let the chocolate set up.  Then make another batch of rice krispies and pat on top of chocolate.
