Well, first, you really need to hop over to "Tammy's Recipes" (see my sidebar for link) and check out her awesome cheesecakes! The orange and vanilla one makes me crave a Creamsicle Pop, LOL!
My tip today is silly, I think, but it works. Do you buy coffee in cans? If you do and you are like me, you probably save them. Well, I found they make a great place to store 'crushable' items like donuts or muffins before you put them in the freezer. Just put as many of the item as you can fit, close the lid, then label the top of the can. This is a good way to put aside a few snacks for later use (don't ice your cupcakes, btw), so that when you are in the mood for something sweet--but you don't feel like baking--all you have to do is take one or two from the can (or all of them, LOL!), let them thaw, then ice and enjoy.
