You can add in different cheeses, as long as they are soft. Rindless brie, Gorgonzola, Delice de Bourgogne are all good in this. Use a different topping, and add some crumbled bacon between the slices. Make the crepes gluten-free if needed. The cake can be made up to three days in advance, and since the cheeses make it rich—one cake serves at least 12 people—you want to slice it on the thinner side.
