Chocolate Peanut Butter Pudding Pie

Preheat the oven to 350°F.
In the bowl of a food processor, pulse the graham crackers and sugar until finely ground. You should have about 1 3/4 cups. Add the butter and pulse until moistened. Use the bottom of a measuring cup, glass, or ramekin to press the crust mixture into the bottom and up the sides of a 9-inch pie plate or springform pan. Bake until fragrant and golden brown, about 12 minutes. Cool completely on a wire rack.

Place the gelatin in a small bowl, add the boiling water, and stir until dissolved. Set aside.
In a medium saucepan, whisk the sugar, cocoa, cornstarch, and salt. Gradually add the milk, whisking until smooth. Set over medium heat and cook, whisking constantly, until the mixture thickens and comes to a boil, about 10 minutes.
Remove from the heat. Add in the peanut butter and chocolate and stir until melted. Stir in the vanilla and reserved gelatin mixture. Pour the pudding into the pie crust. Garnish with the peanuts. Chill the pie in the fridge for at least 3 hours, or preferably overnight, until well chilled and set, before slicing and serving. Store in the fridge, covered, for up to 3 days.
