Preheat oven to 350 degrees. Note: baking is for the crust only and not the cheesecake.
Crust
Use a double boiler to melt chocolate. Add almonds, oats, and salt to a food processor and pulse until a crumbly consistency. Combine in a medium bowl almond mixture, melted chocolate, and coconut oil. Retain 1 tablespoon crumbs for later.
Add crumbs to a 9-inch pie plate. Press crumbs evenly along the bottom and sides, or use a springform pan and press crumbs along the bottom and about 1/2-inch up the sides of the pan. Bake 8 to 10 minutes, remove, and allow to cool completely.
Tip - Place plastic wrap over fingers of one hand and press the crumbs in place or use the bottom of a glass.
Filling
Add canned coconut milk to a medium mixing bowl and beat with an electric mixture on medium-high until thickened, approximately 5-6 minutes. Add cream cheese and coconut sugar and continue beating until sugar is dissolved, approximately 2 minutes.
Add peanut butter, coconut oil, and vanilla, and beat just until incorporated. Pour filling in a cooled crust and refrigerate until set, approximately 5-6 hours.
Topping
Add chilled coconut milk, chocolate chips, and coconut sugar to a medium saucepan. Heat over low heat until all of the chocolate chips are melted and coconut sugar is dissolved. Stir to combine and add vanilla. Remove from heat and allow to cool at room temperature. Pour topping over chilled pie filling and refrigerate until chocolate is set, approximately 2 hours.
