For the last minute pot luck, the summer barbecue that you've had no time to prepare something for, or just for something to munch on in front of a movie, may I humbly suggest some Cookie Dough Dip with pretzels or graham crackers? It'll add no heat to your kitchen, though I make no promise about the calories to your diet...
8 oz cream cheese
half a cup of butter
1 cup powdered (icing) sugar
2 tbsp. brown sugar
1 1/2 tsp vanilla
1 cup chocolate chips/candy bar pieces, etc.
1 cup toffee pieces (could always use another cup of choc chips)
I've only served this with the pretzels or graham crackers, but would be interested to see how it works with fruit or some other dipping option.
Enjoy, however you have it!
