In a medium saucepan, melt the chocolate chips over low heat, stirring frequently until smooth. Remove from heat and allow to cool slightly.

In a large mixing bowl, pour in the heavy cream. Using an electric mixer, whip on medium speed until soft peaks form. Gradually add powdered sugar and continue to beat until stiff peaks form.

Gently fold the cooled melted chocolate into the whipped cream using a spatula. Be careful not to deflate the cream; you want it light and fluffy.

Once the chocolate and cream are combined, fold in the shredded coconut and chopped pecans.

Spoon the creamy filling into the pre-made graham cracker crust. Spread it evenly, ensuring there are no air pockets. Cover with plastic wrap and refrigerate for at least 2 hours to set.

If you prefer a deeper flavor, toast the remaining pecans in a dry skillet over medium heat for about 5 minutes, stirring occasionally until fragrant.

Once set, slice the pie and top it with any remaining toasted pecans and toasted coconut if desired. Enjoy chilled!
