In a mixing bowl, combine the crushed graham crackers, sugar, and melted butter.

Press the graham cracker mixture evenly into the bottom and up the sides of a pie dish.

In another bowl, beat the softened cream cheese and powdered sugar until smooth.

Gently fold in the whipped topping until fully incorporated.

Melt the chocolate chips in a saucepan over low heat, stirring until smooth.

Allow the melted chocolate to cool slightly, then mix it into the cream cheese filling.

Stir in the flaked coconut and chopped pecans if using.

Pour the filling into the prepared crust, spread it evenly, and chill for at least two hours before serving.
