For the custard powder

  • ½ cup white granulated sugar
  • 1 cup cornstarch
  • 1 cup instant milk powder

To make the custard

  • 2 cups milk
  • 2 Tablespoons sugar or to taste see note 1
  • 1 Tablespoon vanilla extract
  • teaspoon ½ ml yellow food coloring (optional) see note 2
  • 3 Tablespoons custard powder


Making the custard powder

  • Blend the powdered milk, sugar and corn flour, in a food processor or blender, for about 1 minute until combined
  • The custard powder can now be used immediately or stored in an airtight jar in the refrigerator for up to 3 months.

Turning the powder into a creamy rich custard

  • Add milk, custard powder, sugar and vanilla extract into a pot.
  • Place the pot on the stove and turn up the heat to low.
  • Stir continuously for about 4 to 5 minutes using a whisk or fork to stir until the custard bubbles and is creamy. see note 3
  • Remove the pot from the stove.
  • If you feel that the custard is too thick, simply add ¼ cup of milk at a time whisking constantly until it reaches the desired consistency. This step can be done when the pot is removed from the heat.
  • Prepared custard that has been left at room temperature for more than an hour or refrigerated becomes thick and sometimes lumpy. To bring the thick cooled custard to a thinner consistency, place it back onto the stove on low heat.
  • Add small amounts of milk (about 2 Tablespoons at a time) to get it to the desired consistency. Remember to whisk continuously.



  1. I added just 2 tablespoons of sugar for my custard. But you can add more or less according to taste. Taste the custard for sweetness before it starts thickens on the stove. Add sugar accordingly.
2. Yellow food coloring can be added if you want to get the classic yellow appearance. Coloring is optional, used as preferred.
3. When preparing the custard on the stovetop, whisk constantly. Whisking ensures that the custard is evenly thickened and reduces the chance for lumps and scorched spots to develop.
