Easy Homemade Chocolate Pudding

In a medium saucepan, combine the cocoa powder, granulated sugar, and cornstarch. Whisk them together until there are no lumps.

Gradually pour in the milk while continuously whisking to create a smooth mixture. Make sure all the dry ingredients are dissolved.

Place the saucepan over medium heat. Cook, whisking constantly, until the mixture thickens significantly and begins to simmer gently, about 5-7 minutes.

Remove the saucepan from the heat. Stir in the vanilla extract.

Pour the hot pudding into individual serving dishes or a single bowl. Allow it to cool slightly at room temperature, then cover with plastic wrap (pressing it directly onto the surface to prevent a skin from forming) and refrigerate for at least 2 hours, or until thoroughly chilled and set.
