Place baking chocolate in glass or ceramic dish. Microwave on HIGH in 1-minute increments until melted. Add cream cheese and microwave, in 30-second increments, until cheese has become soft.
Mix well. Add half-and-half and mix until a thick batter is formed. Mix in Splenda two tablespoons at a time.
Cover a baking sheet with waxed paper. Scoop out batter one spoonful at a time, creating roughly sixteen lumps of equal size. Place tray in fridge and allow to chill several hours or overnight.
If strapped for time, drops can also be chilled in freezer.
