I used two vanilla sheet cakes 16″x16″ cut into bread slice shapes for this cheezy cake.. I iced and fondant covered bottom layer and top layer then filled the middle with butter cream icing. I used orange modelling chocolate for the oozie cheese,  then used spray tint to give the edges a toasted/grilled look to them then coated the whole cake with pipping gel to give it a melted butter look.

The board is covered in squares of colored fondant to give a look of gingham cloth and the sweet pickles on the side are made from a tube of lighter green fondant covered in a thin layer of darker green fondant cut in slices with a veggie slicer. Great responce from the customer ! When ever they take their father (75th birthday) out for dinner or lunch he always ends up ordering a grilled cheese sandwich, this is why they requested a grilled cheese sandwich cake!
