You can put this in your template, but not straight out of the box. It’s probably much easier to copy the essential bits from wp-menu-cart.php (the wpmenucart_menu_item function) and /includes/wpmenucart-jigoshop.php (which is where the data is collected).
Thanks Ewout! I’ll give it a shot if my workaround gives me problems. What I did was make a menu with one page in it, and told the cart to go there, then called that menu into my template. I then hid the page link and overrode a bit of css.
