• Whole Milk/Coconut Milk – Contributes creaminess to the dough; coconut milk enhances flavor and richness.
For the Custard Filling
• Egg Yolks – Enrich the custard filling and help it thicken; no substitutions recommended.
• Cornstarch – Aids in thickening the custard; arrowroot powder can be an alternative if necessary.
• Vanilla Extract – Elevates the flavor of the custard; consider using different extracts, like almond, for variety.

Step‑by‑Step Instructions for Creamy Custard Mochi Balls
Step 1: Prepare the Custard Filling
In a saucepan, whisk together the egg yolks, sugar, and cornstarch until smooth. Gradually stir in the whole milk or coconut milk, cooking over medium heat. Continuously stir for about 5-7 minutes until the mixture thickens and coats the back of a spoon. Remove from heat, then mix in the butter and vanilla extract. Cover with plastic wrap to prevent a skin from forming and chill for at least 30 minutes, then form into small balls and freeze until solid.
Step 2: Make the Mochi Dough
In a mixing bowl, combine glutinous rice flour and sugar, then slowly add milk while stirring until a thick batter forms. Microwave the mixture in 1-minute intervals for a total of 3-4 minutes, stirring between intervals, until it becomes thick, sticky, and translucent. Once cooked, carefully stir in melted butter and allow to cool slightly before handling, ensuring the mixture remains warm and pliable.
Step 3: Assemble the Mochi Balls
Dust your workspace generously with cornstarch to prevent sticking. Divide the mochi dough into equal portions and flatten each piece into a disc. Place a frozen custard ball in the center of each disc, then carefully wrap the dough around the custard and roll it into a smooth ball. Ensure the custard is fully encased in the mochi to maintain its shape, creating a delightful Creamy Custard Mochi Ball.
Step 4: Coat and Chill
Roll each formed mochi ball in crushed vanilla cookies, ensuring an even coating for added crunch and flavor. Place the coated mochi balls on a plate and refrigerate for 20-30 minutes to allow them to firm up. This chilling step enhances the texture, making your Creamy Custard Mochi Balls extra delightful and ready for serving.
