1/2 stick margarine
1 - 8 oz. jar Fluff marshmallow
5 cups Rice Krispies cereal
In a 3 qt. saucepan, melt margarine on low heat and add marshmallow. Stir until all melted and smooth. Remove from stove and add Rice Krispies. Stir until all coated.
Pour in a 9 x 13 x 2 cake pan or 7 1/2 x 11 1/2 by 1 1/2 brownie pan--whichever pan you use, it must be buttered first. Take out a TBSP of mixture at a time and smooth it into the bottom of the pan using the back of the spoon. Repeat until all mixture is in pan. Let cool and cut into squares.
