Instructions

1. Add the milk, sugar, salt, cornstarch, cocoa powder, and egg yolk to a blender. Pulse for 5 seconds to mix everything together.
2. Pour the milk mixture into a sauce pan. Use a spatula to scrape the sides of the blender to get all the sugar that is still on the bottom and sides.
3. Heat over low-medium heat, constantly stirring, until the mixture thickens and starts to bubble. This will take about 6-7 minutes.
4. Reduce the heat to low and cook for 1-2 minutes, stirring often. Remove the pan from the stove top.
5. Stir in the vanilla and butter until smooth and creamy. Pour into 1 bowl or 2 small cups.
6. Place a piece of plastic wrap directly on top of the pudding touching the surface. Let cool on the counter until just slightly warm to the touch.
7. Refrigerate until completely chilled and thickened. Serve with whipped cream and berries.
