Ingredients
- 1 cup milk powder
- 1/2 cup cornstarch
- 1/8 teaspoon yellow food coloring powder plus more if desired
- 2 tablespoons vanilla sugar
Instructions
- Place the milk powder, cornstarch, yellow food coloring, and vanilla sugar in a fine mesh sieve. Sift them into a large bowl to remove any lumps.

- Use a whisk to mix the sifted ingredients until evenly combined. If you want a more yellow color, add an extra 1/8 teaspoon of food coloring.

- Transfer the custard powder into an airtight container. Store in a cool, dry place until you're ready to use it.
