Just for the record... the current recipe for Rice Krispy treats that they show on the box has been modified over the years to lessen the calories and fat. Frankly Scarlett, these things taste like crap with the listed recipe.
So I did a bit of research and found that the original recipe is as follows:
(1) bag of regular marshmallows (about 40 large) or (1) bag in the minis (personally, I like the large but have no technical reason for this)
(1) stick of salted butter (that's right, 8 tablespoons! the current recipe on the box calls for 1/4 or sometimes on the web you see recipes that call for 3 tablespoons. The recipe currently on the box makes little "carboard" tasty treats)
If you haven't tried using a full stick of butter in your treats because you're too young to remember or you simply forgot... try this recipe. You will not believe how much better they taste!
(6) cups of Rice Krispies (when using this original recipe, I recommend adding 1 more cup. With this much butter, the melted mixture has enough volume for the xtra. It also, theoretically, lowers the fat amount, per treat, since you now have more to serve.)
Note: If you are worried about the amount of fat, simply use 6 tablespoons (3/4 of a stick) but don't add the 7th cup of krispies. You will reduce the fat by 25% without seriously changing the end result.
We all know how to do the rest. I also put a light coating of Promise margarine (any soft spread works) on my hands when pressing into the pan. This keeps the little buggers from sticking to your (watch out, they're hot at first) fingers. If you're worried about using your hands in food that others will eat, you simply put a bit of the margarine on the bottom of a large spatula and press like that. (I don't worry about other people... most batches are polished off by me in the first day!) If they are sticking to your fingers, then you run into the issue of having to lick them off and we all know where that will lead to..... pretty soon, your batch is a bit lighter! The Promise also keeps them from sticking to the pan and it adds a slightly different buttery taste that compliments the real butter in the treats. One final trick... press them down tight. The tighter the press, the longer the treats take to eat.
The only other variation I've tried is serving them with thin slices of banana on top. That makes for a really unique treat!
