Step 1

Combine 1/2 cup milk and cornstarch in a small bowl. Whisk or stir with a fork until smooth and all lumps have been incorporated.

Step 2

Combine remaining milk with sugar in a medium saucepan over low heat. Slowly whisk in the cornstarch mixture. Cook, whisking as needed to prevent lumps from forming, until mixture begins to thicken, 8 to 10 minutes. Add chocolate chips and salt. Continue stirring until chips are completely melted and pudding is smooth and thickened, about 7 minutes more.

Step 3

Pour pudding into 1 large bowl or 6 individual bowls. Place plastic wrap directly on top of the pudding to prevent a skin from forming; smooth it gently against the surface. Refrigerate for at least 3 to 4 hours before serving.
