Bittersweet chocolate pudding Recipe

In a medium saucepan, whisk together the cornstarch, cocoa powder, sugar, and salt.

In a separate bowl, combine the milk and egg. Gradually pour this milk mixture into the saucepan, whisking constantly until everything is thoroughly mixed and smooth.

Place the saucepan over medium heat, stirring constantly. Continue stirring until the mixture comes to a boil, then let it cook for another 1 minute, still stirring, until it visibly thickens.

Remove the saucepan from the heat and stir in the butter and vanilla extract until they are fully incorporated and melted.
