Mix dry ingredients. In a medium saucepan, whisk together sugar, cornstarch, and salt. Easy, no explosions yet.
Add milk slowly. Pour in milk while whisking constantly. The goal is smooth pudding, not a lumpy horror movie.
Cook over medium heat. Heat the mixture until it thickens, whisking occasionally. You’ll see it start to cling to the whisk—victory is near.
Add chocolate. Remove from heat, then stir in chopped chocolate and vanilla until smooth. Cue the chocolate aroma dance.
Pour into crust. Transfer your silky chocolate pudding into the graham cracker crust. Smooth it out like you actually know what you’re doing.
Chill. Refrigerate for at least 2 hours. Patience is hard, I know. But worth it.
Top and serve. Whipped cream, chocolate shavings, sprinkles—your call. Enjoy the adoration from anyone who sees this masterpiece.
