Preheat oven to 350 degrees Fahrenheit (180 degrees Celsius). Place chocolate cookie crumbs in a bowl and add melted margarine and oil. Mix until well combined.

Grease a 9-inch round tart pan with a removable bottom and pour the crumb mixture into it. Smooth it onto the bottom of the pan and up the sides to create the crust for the pie. (I like to use the bottom of a flat measuring cup to smooth it out.)

Meanwhile, in a double boiler, melt the chocolate with the whipped topping or coconut milk. Mix occasionally until combined. When it reaches a smooth consistency, remove from heat and let rest for two minutes.

Add the Delinut chocolate spread and mix well to combine.

Place it on a baking sheet and bake for 10 minutes. Remove from oven and allow to cool.

Pour into the baked pie shell and let cool. The mixture will harden on its own. Sprinkle with cocoa powder before serving.
