​​Cookie Crumb Crusts are so under-rated!!!  I love them for cheesecakes, ice-box cakes, and pies!  They are so easy.  Most of us usually turn to the old faithful graham cracker crust, but there are more possibilities.  The ones below work very well for crumb crusts and have flavors which pair well or enhance with certain your dessert’s main ingredients. 
Another bonus for using cookie crumb crusts is that you can use gluten-free cookies, which are available most everywhere.  I’ve even used gluten-free animal crackers!
