Moose Tracks! (That's the kind with pb cups and fudgey bits -- I adore those fudgey bits!)
I also like chocolate, vanilla -- boring, I know, but I especially like vanilla on either apple crisp or cake-top chocolate pudding. (Volcano cake-ish recipe I've been making since before I ever saw volcano cake.)
My least favorites would be coffee, any fruit flavor (I like fruit, just not in things -- other than that apple crisp!) or anything with nuts.
