We LOVE these!
The trick is to add extra marshmallows at the end- they turn out soft and gooey every time.
5 T butter
8 c + 2 c mini marshmallows
6 c Rice Krispies
Spray a 9x13 pan and set aside.
In a large bowl, combine Rice Krispies and 2 c marshmallows.
Melt butter in large pot. Add 8 c marshmallows and stir until melted.
Pour over Rice Krispies and extra marshmallows and mix.
Press into pan and let set up.
