1 cup heavy cream
¾ cup milk
1 fresh egg
1 tsp vanilla
½ cup Splenda (for baking)
Mix all ingredients in a 1 lb coffee can. Cover with the lid and tape with duct tape. Put the small coffee can into a larger, 3 lb coffee can. Fill the space inside the can with ice and sprinkle generously with rock salt. Tape the lid on tight. Have a game of keeping the can moving by kicking it around the yard for 25 minutes. Open and serve.
