*Use GF graham crackers for a GF/Passover-compliant version. Kinnikinnick has GF graham crackers and a GF graham cracker crumbs product. Check Vitacost or your local grocery store. ThriveMarket.com sells Schar GF graham crackers, Pamela's GF graham crackers, as well as Mi-Del GF graham cracker crust (you can bake the cheesecake in the pie plate or remove from the aluminum tin and transfer to your own baking dish.). Or don't use graham crackers and use a vanilla wafer or similar.
**Or use an equal amount of firm tofu. I haven't tested it with a different yogurt, but I imagine some of the thicker DF yogurts like the Kite Hill coconut yogurt would work well.
