-*Veritable Petit Buerre crackers are a plain slightly sweet biscuit-type cracker sold in Europe. I had some in my pantry and used them in this recipe. Don't feel like you need to use up your stash of imported crackers or cookies to make this recipe. Any type of dry, sweet cracker or cookie will work. Or you may use all graham crackers instead of combining two types of cookie.
-If you want to make a really thick bar, use a 9x9 pan and bake for an additional 8 minutes on the lower third of the oven.
