Milk Chocolate Custard Cups Recipe

Combine sugar, cocoa, and cornstarch in a medium heatproof bowl.

In a medium pot, bring milk to a simmer over medium heat.

Whisk yolks into cornstarch mixture. Pour in half a cup of hot milk into the bowl, whisking continuously, until homogeneous. Add the rest of the milk in a continuous stream, still whisking, to ensure that the eggs don't get scrambled. Pour the mixture back into the pot.

Over medium-low heat, bring the mixture to a boil, stirring constantly with a heatproof spatula. Remove from heat.
