To make a vegan chocolate pie, first you need to prepare the ingredients. First, you'll need the following ingredients: 1 cup (240 ml) granulated sugar 1 tablespoon (2.5 g) cocoa powder 2 tablespoons (60 milliliters) of vegetable oil 1 teaspoon (0.5 tsp) vanilla extract Instructions: Preheat the oven to 375 ?F (191 oC) and grease and flour two 9-inch (23 cm) pie pans. Line the bottom and sides of the pie shells with parchment paper. Set aside. In the bowl of an electric mixer, cream together the butter and sugar until light and fluffy. Add the eggs and vanilla and mix until combined. Pour the dry ingredients into the wet ingredients and beat until they're just combined and no streaks of egg remain. Gradually stir in the chocolate chips until the mixture reaches your desired consistency. Fill the crusts about two-thirds full with the batter. Bake for 20 minutes or until browned. Allow to cool before cutting into squares and serving.
