Place all the ingredients into food processor or high powered blender.
Blend until solid and slightly sticky. It will become a large lump with most of it stuck together.
Grease a pie pan with butter and then coat lightly with almond flour. Make sure you go all the way up the sides too.
Place the date mixture into the pie pan and begin pressing it across and around the pan. You can use wax paper or more almond flour to keep your fingers from sticking.
Continue pressing until the mixture fills the pie pan like a crust. Trim any extra (although you likely won't have any). You can eat the extra, it's good!
Chill until ready to add your filling.
