These bars are the speediest things to prepare, using just a microwave and a spatula. I whip them up for my kids, for a simcha, or whenever.
10½ oz miniature marshmallows
1 cup peanut butter
1 cup semi-sweet chocolate chips
½ cup margarine
2 cup rice krispies
1 cup chopped nuts (optional)
In a very large microwave-safe bowl, combine first four ingredients. Cover and microwave on high for 2 & 1/2 minutes.
Stir; then, add the last two ingredients. Stir until well mixed
Spread into a greased/sprayed 9″ x 13″ pan. Cover and refrigerate for about 2 hours
Cut into squares and enjoy.
