Whisk together the sugar, cornstarch and salt in a medium saucepan. Briskly whisk in the egg yolks and the milk.

Place the mixture over medium heat and cook, whisking often, until the mixture bubbles and thickens.

Once it has bubbled for a full minute, remove from the heat and mix in the butter and vanilla. Stir until the butter melts and the mixture is smooth.

Pour into 6-8 small glasses with a layer of crushed cookie on the bottom. Cover each glass with a small piece of plastic wrap and place in the refrigerator until cool.

Once the pudding is chilled, remove from the fridge and top with another layer of crushed cookies. Add sprinkles, whipped cream and for good measure, a few more sprinkles. Enjoy!
