Plain Yogurt Recipes??? GIVEAWAY

So I sorta goofed.  My 2 year old daughter eats plain yogurt twice a day - once before her nap and once before bed.  So - when we buy plain yogurt, we buy a lot of it.  Last month, we ordered it through our natural foods co-op, because it was a bit cheaper that way.  We ordered 12 quarts.  When they came, they had about a one month shelf life.  Perfect - we had ordered about a one month supply.  When I ordered for this month, we weren't as fortunate.  My co-op order came in on March 21.  The sell-by date on the yogurt was March 29.  That gave us 12 quarts of high quality, organic, full-fat, plain yogurt to use in eight days.  So - here it is, March 29th and I still have eight of the twelve quarts to use.  They don't freeze well - I've tried.  I can't be certain - but my guess is that I have about a week to ten days to use them. 

So this is where I need your help.  Do you have any creative ways to use up plain yogurt?  Any recipes that call for it?  PLEASE leave a comment, including your recipe or a fun way to use this stuff.  If you post a comment, I will enter you into a random drawing to win something fantastic.  I haven't decided what I'll give away yet - but I promise it won't be an expired quart of plain yogurt.  :)  Please send me your ideas by April 5th.  Thanks for your help.  I will post an update - with the prize details - within the week.
