Ingredients

1/2 cup butter
1/2 cup brown sugar
3 cups Rice Krispies
2 cups flake coconut
1 cup chopped walnuts (optional)
1/2 gallon vanilla ice cream, softened
(chocolate sauce recipe below)

Cook butter and brown sugar in a large sauce pan until brown sugar is dissolved, turn off heat. Meanwhile, in a separate bowl, combine cereal and coconut and add to sugar mixture. Press 2/3 of cereal mixture in a 9x13 pan. Put into freezer for five minutes and stir ice cream and spread over mixture in pan. Sprinkle over the top with the rest of the mixture and freeze for at least one hour before serving. Serve with chocolate sauce, recipe below.

I've never tried it but DW says cherry pie filling is good over it too.
