Step‑by‑Step Instructions for Creamy Custard Mochi Balls
Step 1: Make the Custard
In a medium saucepan, whisk together the egg yolks, sugar, and cornstarch until smooth. Gradually pour in the whole milk while continuing to whisk. Place the saucepan over medium heat and cook, constantly stirring, until the mixture thickens and bubbles gently, about 5–7 minutes. Once thickened, remove from heat, stir in the butter and vanilla extract, then transfer to a bowl. Cover with plastic wrap directly on the surface and chill in the refrigerator for 30 minutes until firm.
Step 2: Prepare Mochi Dough
In a large mixing bowl, combine the glutinous rice flour and sugar, mixing until evenly distributed. Gradually add the milk, stirring to form a smooth batter. Transfer the mixture to a microwave-safe bowl and heat in the microwave for 1-minute intervals, stirring between each, until the dough becomes thick and sticky—about 3 to 4 minutes total. Mix in the melted butter, let it cool slightly until it’s comfortable to handle, and prepare to shape your Creamy Custard Mochi Balls.
Step 3: Assemble Mochi Balls
Dust your hands with cornstarch to prevent sticking as you take small pieces of the mochi dough. Flatten each piece into a round disc, then place a chilled custard ball in the center. Carefully wrap the dough around the filling, pinching to seal completely, and gently roll into a smooth ball shape. Repeat this process until all custard is encased in mochi, ensuring each ball is well-formed for a delightful texture in your Creamy Custard Mochi Balls.
Step 4: Chill and Serve
Once all the mochi balls are shaped, roll each one in crushed vanilla cookies for a crunchy coating. Place the coated mochi balls on a plate or tray and refrigerate for 20-30 minutes until firm. This step brings out the best texture and flavor. Serve your Creamy Custard Mochi Balls chilled for an indulgent treat, or you can store any leftovers in an airtight container in the freezer for later enjoyment.
