Is there someplace I can purchase some deep cookie cutters so that I may make my Rice Krispie Treats thicker and still cut them neatly?

If you are looking for a straightforward shape (i.e. circle) you could always just get some biscuit cutters.

If you want fun, cookie-cutter shapes, check out the thread on how to make your own - you could just cut the metal to a wider strip. I don't have the link, sorry, but it's around here somewhere .

Thank you. I've seen that thread before and will search it out.
