Great idea for lunches -- make smoothies, freeze them, then put them in their lunchboxes frozen (they will thaw before lunch plus act as a cold pack for other things). - I do this and it works really well. If you use a thermos then it is still icy at lunchtime.
Cinnamon roll pancakes... Mix melted butter, brown sugar and cinnamon, put in a squeeze bottle and squirt onto pancake batter on the griddle.
