EASY Vanilla Fudge Recipe?

I want to make vanilla fudge but do not have a candy thermometer. I'm looking for a recipe for a creamy, tasty fudge that does not require the use of a thermometer.
Preferably a blend and let set recipe, but always open to suggestions.

Update: Only Vanilla fudge recipes please. I do not like chocolate or peanut butter. Thanks! :)
