Crispy rice treats filled with vanilla ice cream. Purchased in Stop & Shop's natural foods section.
Of course, they don't look anything like on the package. The crispy rice shell is thicker than advertised, squatter, and filled with less ice cream, if you can call it "filled". The top one in the first picture is what you really see after biting into one. These are more like Rice Crispies Treats ice cream sandwiches with the sides pinched closed. They're okay, but I expected better for $3.79.
