Start by gathering all your ingredients and measuring them out. This makes the cooking process smoother and more enjoyable.
In a medium bowl, whisk together the granulated sugar and cornstarch until well combined. This will help prevent clumps in your custard.
In a saucepan over medium heat, warm the low-fat milk until it’s hot but not boiling. Stir occasionally to prevent it from scorching.
In another bowl, whisk the eggs and pure vanilla extract together until they are fully blended.
To prevent the eggs from scrambling, slowly pour a small amount of the hot milk into the egg mixture while whisking continuously. Gradually add more milk to the egg mixture until fully combined.
Pour the egg mixture back into the saucepan with the remaining milk. Stir constantly over medium heat until the custard thickens and coats the back of a spoon, about 8-10 minutes.
Remove the custard from heat and strain it through a fine-mesh sieve into a clean bowl. This step ensures a silky texture. Allow it to cool before serving.
