Mars Crispy Bars

I forgot to take a photo but here is the recipe:

4 Mars Bars (Chopped)

1/2 cup butter or margarine

3 cups Rice Krispies

1 cup of semi-sweet chocolate chips

1/4 cup butter or margarine

Heat Mars bar pieces and first amount of butter in large saucepan on lowest heat, stirring constantly until smooth. Remove from heat.

Add cereal. Stir until coated. Press in greased 9x9 pan.

Heat chocolate chips and second amount of butter in small saucepan on lowest heat, stirring often until chocolate is almost melted. Do not overheat. Remove from heat and stir until smooth. Spread evenly over cereal mixture. Chill until set.
