Answering some of my own questions.... I filled the muffin tins full, and that's how they were when cooked - they don't "rise." I baked 18 muffins for 25 minutes. When I used a spatula to pull one out of a tin, the bottom was like a regular muffin. They did not fall apart. I let them cool about 15 minutes in the pan, but I don't think this matters a great deal. I forgot to mix the sugar in the cream cheese mixture, and they tasted great without it, so that's an option to save calories. Now, I just want to know: Do I store them in the refrigerator????
