The ingredients/amounts look the same but you are right, with the muffins it doesn't look as much like a casserole. And ME TOO....mmmm sour cream...I thought this was different. You can serve it up per person (for 4 obv it is limited for a group) and it won't look like a casserole as much.
PS If you serve me sour cream on anything I will be your friend. .
