Start by combining the chocolate graham cracker crumbs and granulated sugar in a medium bowl. Pour in the melted unsalted butter and mix until the crumbs are evenly coated and resemble wet sand. Press this mixture firmly into the bottom and up the sides of your 9-inch pie dish to form an even crust layer. Pop it into the fridge while you prepare the filling to help it set.
In a chilled mixing bowl, beat the heavy cream with an electric mixer until stiff peaks form. Set aside this fluffy whipped cream, which will give your pie its light and airy texture.
In another bowl, beat the softened cream cheese and powdered sugar together until smooth and creamy. Add the sour cream and peppermint extract, mixing until everything is well incorporated and silky.
Place the semi-sweet chocolate chips in a microwave-safe bowl and heat in 20-second intervals, stirring between each, until completely melted and smooth. Let it cool slightly so it doesn’t curdle the cream cheese mixture when combined.
Slowly add the melted chocolate to the cream cheese mixture, folding gently to blend the flavors without overmixing. This blend is what makes the pie so decadently chocolatey.
Carefully fold the whipped cream into the chocolate-cream cheese mixture. This step is crucial to maintain the light and fluffy texture that makes this pie stand out.
Pour the filling into the prepared crust and smooth the top with a spatula. Sprinkle the crushed peppermint candies evenly over the surface for a festive, crunchy finish. Refrigerate the pie for at least 4 hours, or overnight for best results.
Once chilled and set, slice into generous pieces and serve chilled. The combination of creamy chocolate and refreshing peppermint will have everyone asking for seconds!
