Fluffy fruit dip?

A few months ago at a party I had some amazing fluffy fruit dip - it was kind of like thickened cool whip.  I asked what was in it and was told cream cheese and powdered sugar.  However when I searched for recipes and tried to make something similar myself, the dip comes out to the consistency of salad dressing - runny and not fluffy at all!  I am not adding any liquid, it just seems like the whole thing dissolves into a liquid when I beat it (per recipe instructions)

Does anyone have any good recipes for a nice fruit dip that is not runny, or some tips on making one?  No yogurt please!

Thanks!

I bet what you has was a block of cream cheese mixed with a jar of marshmallow fluff.    I don't think they make light fluff, however you could use light or free cream cheese probably.

I have a very old recipe somewhere that uses instant vanilla pudding (sugar free is fine) combined with Cool Whip.  Give me some time to dig it out.

Found it!

1 6 oz pkg sugar free instant vanilla pudding
1 12 oz container fat free frozen whipped topping

Thaw the topping and beat in the pudding mix until fluffy.  Refrigerate for at least 15 minutes before serving.
