Preheat oven to 350 degrees F. Whisk the eggs, oil and vanilla extract in a food processor or stand mixer. Blend. Add the remaining ingredients and process until combined. Add the cold, cubed butter.
Process by pulsing until it looks like crumbles. Spray a 9 inch pie plate with cooking spray and pour crumbles into pie plate.
Press with hands to form dough right in the pie plate. Using a fork randomly make holes into the bottom of the crust. Cover crust with silicone shield or aluminum foil. Bake the crust 10 minutes or until golden. Remove from oven and set aside.
Make the Chocolate Filling
Pour in all ingredients into a stand mixer or use an electric hand mixer. If you are concerned about the sweetener, wait to add the eggs so you can taste the filling then adjust sweetener if needed. Once it's to your liking, blend in the eggs.
Pour filling into the prepared pie crust. Cover the crust edges with silicone mold or aluminum, foil to prevent burning crust.
Bake 35-40 minutes or until center just slightly jiggles but is set and not glossy. See two serving options above within post.
