These days it's usually a small dish of sugar free vanilla ice cream with no toppings.
For a special treat or a lazy dessert for company I like one of the following.
A Tin Roof Sundae with sugar free Hershey's syrup and a few Spanish peanuts.
Wet Nuts, made with sugar free maple flavored pancake syrup and walnut pieces heated in the microwave.
Seasonal berries or fresh peaches with a little artificial sweetener.
All of these are definitely better if made with proper vanilla ice cream and real topping ingredients, LOL!
