Divide the snow skin dough into two sizes: 10-gram and 18-gram.
Divide the coffee cream cheese custard filling into 10-gram and 18-gram portions.
Place the coffee cream cheese dough on a plate, cover it with plastic wrap, and chill in the refrigerator for at least 30 minutes. If your room is cool, you can skip this step.
Gently flatten it into a disk, thinning the edges to increase the surface area. Place the filling in the center.
Wrap the filling with the snow skin dough, ensuring tight edges.
Roll the mooncake between your gloved palms to form a smooth ball.
Shape the dough for the capybara body into a slightly oval form. For the ears, roll two small balls, and for the mouth, flatten a small piece of dough into an oval shape. Draw a Y on the oval disk to represent the mouth. Attach the ears and mouth to the body as needed.
Place the snow skin mooncakes into an airtight container and freeze them overnight.
Before serving, transfer the mooncakes to the fridge for 1 hour to achieve an optimal texture. Alternatively, leave them at room temperature for 10-20 minutes.
