You can actually order a double Warm Cookie Ice Cream Sandwich. For real. Take one ice cream sandwich, put a second ice cream sandwich on top, then yell, "Amirite!?"
Take that sandwich and split it into its constituent parts. Cookie. Ice-cream. Cookie. Boom: a three-course meal.
In a Sundae
If Warm Cookie Ice Cream Sandwiches aren't enough, ask for a bowl and some toppings to create your Warm Cookie Ice Cream Sandwich Sundae. It's a thing.
Consume entire ice cream sandwich as normal, leaving one morsel at the edge of your lip, in your beard, or on a strand of hair. When someone mocks you and asks if you’re saving it for later, balk at their ridiculous question. Then, savor that last bit (later).
