Make the Mochi Dough:

• In a bowl, whisk together the glutinous rice flour, cornstarch, sugar, and milk until the mixture is smooth.
• Strain the mixture to remove any lumps.
• Cover the bowl with plastic wrap, poke a few holes, and microwave for 4 minutes, stirring halfway through to ensure even cooking.

Assemble the Mochi:

• Divide the cooked mochi dough into 8-10 pieces.
• Lightly flour a clean surface and flatten each piece of dough.
• Place a spoonful of the whipped cream and nut mixture into the center of each piece, then carefully pinch the edges together to seal and form a ball.
