3 tbsp. butter
1/2 c. light brown sugar, firmly packed
2 tbsp. cream
1/2 c. chopped walnuts
1 c. miniature marshmallows

Cream the butter. Add the sugar gradually and blend well. Stir in the cream. Add the walnuts and marshmallows, mixing lightly. Spread on top of a baked 9 inch square cake, which has not been removed from the baking pan. Broil slowly about 5 inches below the heat for 2-3 minutes until the top is bubbly and lightly browned.
