In a medium saucepan, combine sugar, with cornstarch and salt. Mix to combine (Note: this is all done OFF-HEAT).
Slowly add milk to the saucepan and stir ingredients together. Cook over medium-low heat, stirring constantly, until mixture begins to thicken (Note: you may see or may not notice boiling however the mixture will be hot).
In a small bowl, beat egg. While beating the egg, slowly incorporate a stream of the hot milk mixture into the egg.
Remove saucepan from the heat and add all of egg mixture back into the milk mixture while whisking vigorously. Return saucepan to heat.
Continue to stir on medium-low until thickened. Add vanilla extract and butter. Stir to incorporate.
For chocolate custard: add 1 tbsp of cocoa (unsweetened) to the sugar/ cornstarch/salt mixture at the outset. Alternatively, you can add a piece of chocolate to custard while it's thickening (add chocolate as desired).
Cover in plastic wrap and allow to cool.
