These are so good! I didn't even make them evil! Just to mix it up a bit, I started making them with just mangoes, got the urge to toss a banana in there, so I did. I ended up with some extra mix (about 8 ounces)because I wasn't sure how much mango I should use in place of the 3 remaining bananas, but DH drank it as a smoothie anyway. Oh, all I had was regular skim milk and vanilla lowfat yogurt, so I had to make those substitutions. I think it all evened out in the end, because the recipe just had the vanilla flavor in the milk rather than the yogurt. Yummy, yummy, yummy!
