Need high-cal shake ideas

Can anyone help me come up with ideas for high calorie shakes that are low in sugar? I'm really bad at coming up with recipies that taste good. I have these Benecalorie Resource things from my nutritionist that are liquid and have 330 calories in 1.5oz that I can mix in to help.

(Dropped another pound - waiting for the clinic to open tomorrow to try to get an earlier doctor's appointment. Thought I'd experiment with new stuff in the meantime.)

add milk, frozen fruit like berries and pb to you shakes.  I did it and gained real fast!!

Bananas are really good in a shake..Protein powder and soy milk (or regular milk) with some malt powder...YUMMY!

This is what we added to shakes for our anorexics and burn patients that needed calories:
Peanut Butter, Regular Butter, Protein, eggs (raw), chocolate
