Step‑by‑Step Instructions for Creamy Custard Mochi Balls
Step 1: Make the Custard Base
In a medium saucepan, whisk together egg yolks, sugar, and cornstarch until smooth. Gradually pour in your choice of whole milk or coconut milk while whisking to combine thoroughly. Place the saucepan over medium heat, stirring steadily until the mixture thickens and coats the back of a spoon, which should take about 5-7 minutes.
Step 2: Finish the Custard
Once thickened, remove the saucepan from the heat and stir in unsalted butter and vanilla extract until fully melted and incorporated. Pour the custard into a bowl, cover it with plastic wrap directly on the surface to prevent a film from forming, and let it cool at room temperature for about 30 minutes until it firms up.
Step 3: Freeze the Custard
After the custard has cooled, scoop it into small balls using a melon baller or teaspoon, and place them on a baking sheet lined with parchment paper. Transfer the baking sheet to the freezer and freeze the custard balls until solid, which should take about 2 hours. This will make wrapping the custard easier later.
Step 4: Prepare the Mochi Dough
In a heatproof bowl, combine glutinous rice flour and additional sugar. Gradually mix in milk, stirring until you have a smooth batter. Cover the bowl with plastic wrap and microwave the mixture in 1-minute intervals, stirring in between each, until thick and sticky, which typically takes about 3-4 minutes.
Step 5: Shape the Mochi
Once the mochi dough has thickened, allow it to cool slightly, then dust a clean surface and your hands with cornstarch to prevent sticking. Portion out the mochi dough and flatten each piece with your hands into a circle. The dough should be pliable but not too hot to handle.
Step 6: Encase the Custard Balls
Take a frozen custard ball and place it in the center of a mochi circle. Carefully wrap the mochi around the custard, pinching to seal the edges and forming it into a ball. Repeat this process with the remaining custard and mochi dough, ensuring each ball is well-sealed to prevent leaking.
Step 7: Coat and Chill the Mochi Balls
Once you’ve formed all your Creamy Custard Mochi Balls, roll them in crushed vanilla cookies for added crunch and flavor. Place the coated mochi balls on a plate and chill them in the refrigerator for 20-30 minutes before serving to firm up a bit more and develop their delightful textures.

Make Ahead Options
These Creamy Custard Mochi Balls are perfect for meal prep enthusiasts looking to save time during busy weeks! You can prepare the custard filling up to 24 hours in advance by cooling it, then scooping it into balls and freezing them until solid. The mochi dough can also be made up to 3 days ahead; simply store it in the refrigerator wrapped tightly to keep it fresh. When you’re ready to serve, just wrap the frozen custard balls in the chilled mochi dough, coat with crushed vanilla cookies, and let chill for 20-30 minutes. This way, you’ll have a joyful and delightful dessert ready to impress with just a bit of finishing touch!

Creamy Custard Mochi Balls Recipe FAQs
How do I select ripe ingredients for my custard?
Absolutely! Choose fresh, high-quality eggs with undamaged shells, and look for milk that is within its expiration date. If using fruit purees for variations, select ripe fruits that are fragrant and slightly soft to the touch, as they will provide the best flavor for your custard filling.
What is the best way to store Creamy Custard Mochi Balls?
Store your mochi balls in an airtight container in the refrigerator for up to 3 days. If you want to keep them longer, they can be frozen. To do this, lay them out in a single layer on a baking sheet and freeze until solid, then transfer them to a freezer-safe bag. They’ll stay delicious for up to 3 weeks!
Can I freeze the Creamy Custard Mochi Balls?
Yes, indeed! After wrapping the custard in mochi dough, freeze the filled mochi balls until they are solid. This should take about 2 hours. To store, place the frozen mochi in a single layer in a freezer-safe bag. When you’re ready to enjoy them, let them thaw at room temperature for about 10-15 minutes to soften slightly.
What if my mochi dough is too sticky or hard?
Don’t worry! If your mochi dough is too sticky, use a generous amount of cornstarch on your hands and working surface to help manage the stickiness. If it turns out too hard, it may have been microwaved for too long. In that case, you can try adding a splash of warm water to soften it a bit, but only do this gradually to avoid making it overly wet.
Are there any dietary considerations I should keep in mind?
Great question! The recipe for Creamy Custard Mochi Balls is naturally gluten-free when using glutinous rice flour. However, check for allergies, especially if using flavored fillings, as certain fruits or chocolates may not be suitable for everyone. Additionally, ensure that all packaged ingredients, like vanilla extract or cookies, are certified gluten-free if that is a concern.
How can I ensure my custard is perfectly smooth?
To achieve a creamy texture, stir the custard continuously over medium heat until it thickens, which should take about 5-7 minutes. Make sure to remove it from the heat as soon as it coats the back of a spoon, as overheating can lead to curdling. After preparing, cover the custard with plastic wrap pressed directly onto its surface to prevent a film from forming while it cools.
