I am looking for a butterscotch sauce for ice cream which is comparable to the sauce used at Dairy Queen it is thin and very very sweet.

I'm not sure about being similar to Dairy Queen's sauce as I haven't been there in ages, but this is the recipe I use

Butterscotch Sauce

1-cup packed brown sugar
1-cup corn syrup
1/4-cup butter
3/4-cup whipping cream (35%)

In a medium saucepan, combine sugar, corn syrup and butter
Stirring constantly, cook over low heat until sugar is dissolved
Increase heat to medium high and bring to a boil
Remove from heat
Being careful not to splatter, gently stir in the cream until it's smooth
Serve over ice cream warm or refrigerate and serve cold

Makes about 2 cups
