I followed this recipe, but left it plain (no garlic butter) to make it more versatile.
It would be nice if the recipe were more specific about the thickness or diameter of the discs. Mine were apparently too thick since they stayed persistently squishy. After they cooled, I sliced one horizontally and toasted it for 30 minutes in the toaster oven. That firmed it up nicely and it was quite tasty with lots of butter.
