I just made this the other day, and oh so good...

1 package of firm silken tofu (i used mori nu)
1 cup of vegan chocolate chips
1/4 cup maple syrup
1/4 cup rum
1 tsp. vanilla
*Puree the tofu, rum, maple syrup and vanilla until very smooth and creamy
*Melt the chocolate chips and combine with the tofu mixture. Make sure to mix well.
*Pour into crust and chill.

You can use a graham cracker crust, or make one out of crushed walnuts with a little flour and sugar (press into pie pan and bake, then cool before filling.)
