In a bowl, whisk egg yolks, sugar, cornstarch, and salt.
Slowly pour warm milk into egg mixture while whisking.
Return mixture to saucepan.
Cook over medium heat, whisking constantly, until thick and bubbling.
Remove from heat.
Stir in butter and vanilla.
Press plastic wrap directly on surface and chill until fully cold.
