Rice Crispie Bars, 2 ways

Rice Crispie Bars #1
(technically these are Special K bars, because that's where the original recipe came from. I don't think these fit into their new "replace 2 meals with cereal" diet plan, though)

1 cup sugar
1 cup light corn syrup
Bring to boil and remove from heat
Stir in 1 cup peanut butter, blend well.
Quickly stir mixture into 6 cups cereal (rice crispies)
Press into greased 9x13 pan
Top with 2 cups chocolate chips and let melt, then spread like frosting
Let cool


Rice Crispie Bars #2

40 large marshmallows
2 T butter
Melt in microwave (30 seconds, stir, repeat until melted)
Quickly stir mixture into 6 cups cereal (rice crispies)
Press into greased 9x13 pan
Let cool
