Who Ate My Rice Krispy Treats?

My mom knows that I absolutely love Rice Krispy treats. In fact, one of the many things I look forward to about visiting her next week is that I know that I can count on her to make a batch for me! I'm not exaggerating - I actually got really excited about Rice Krispy treats last night and couldn't remember why I don't make them for myself. So, I decided to whip up a batch.
Well, there are two reasons. The first reason is obvious and struck me immediately upon my first bite - Mom makes them with the perfect marshmallow/cereal ratio that I never can seem to duplicate in my own kitchen. The second reason didn't hit me until this afternoon - it's because the pan looks like this 24 hours after the marshmallows cool...
"So," you ask, "Who ate all the Rice Krispy treats?" And the only honest answer is, "ME!"
