We all scream for ice cream

Ready?

Make up some rice krispy-marshmallow-butter stuff. Butter the outside of a small bowl. Put the stuff around the bowl, in a bowl shape. Let set. Fill with ice cream and enjoy.

Notes:
1) These were made using a small cereal bowl. They are too big. Next time I'll use the outside of a baby food bowl. You want something that will hold just a scoop of ice cream. Two scoops is too much richness.
2) I'm a big fan of drizzling melted butterscotch chips over the finished rice krispy bars. So we did the same thing here, using a spoon to coat the inside of the bowl. Brilliant.
3) You can also use melted semisweet chocolate chips to line the inside of the bowl. The one on the right has both chocolate and butterscotch.
