• Start by preheating your oven to 375 degrees F (190 degrees C).

For Pie Crust:

• Cover the pie crust with parchment paper or aluminum foil and fill it with pie weights or dried beans.
• Place the crust in the oven and bake until the edges turn golden, about 15 minutes. After baking, remove the parchment along with the weights. Puncture the base of the crust with a fork thoroughly.
• Continue baking the crust for an additional 14 to 15 minutes until the bottom develops a golden hue.

For Filling:

• Lower the oven temperature to 325 degrees F (165 degrees C). In a medium-sized mixing bowl, combine sugar, butter, eggs, flour, cocoa powder, and vanilla. Mix until everything is fully blended.
• Pour the mixture into the baked crust and return it to the oven.
• Bake until the filling is firm, taking approximately 25 to 30 minutes. Allow the pie to cool to room temperature before slicing to serve.
