|Microwave the marshmallows and half the butter on high for 4 minutes. |
Add Rice Krispies.
Put 1/2 of this mixture into a 9x13 inch pan. Put the other half into another 9x13 inch pan.
Microwave the caramels, the other half of the butter and sweetened condensed milk on high for 4 minutes.
Pour this caramel mixture over one of the pans of Rice Krispies mix.
Tip out the other Rice Krispies mix from the other pan and put on top of the caramel.
Cool before cutting.
**NOTE: I only use 1/2 to 1/3 of the caramel mixture. Leftover caramel sauce is great with cut up apples.
