Matcha Snow Skin Mooncakes

I put off making matcha snow skin mooncakes for two years because they looked complicated. Turns out they’re not, not even close. The dough comes together with four ingredients, there’s no baking involved, and the whole process takes under an hour.

I made a batch for Mid-Autumn Festival and had to stop myself from eating three before they even chilled properly.

Ingredients

Snowskin Mooncake Dough

• 1 tsp matcha powder
• 50 g mochiko flour (sweet rice flour / glutinous rice flour)
• 57 g water
• 150 g sweetened white bean paste (shiro an)

Mooncake Filling

• 6 pieces red bean neri yokan

How To Make Matcha Snow Skin Mooncakes Step by Step

1. Prepare the filling. Cut the red bean neri yokan into 6 equal pieces and roll each one into a smooth ball between your palms. Place them on a small plate and refrigerate for at least 20 minutes so they firm up enough to wrap cleanly.
2. Mix the dough base. In a medium bowl, combine the mochiko flour and water. Stir until a smooth dough forms with no dry pockets. It should feel soft and slightly sticky, similar to fresh mochi dough.
3. Steam the dough. Transfer the dough into a lightly oiled heatproof bowl. Steam over medium heat for 15 to 18 minutes, until the dough is fully cooked through and no longer looks opaque in the center. It will feel quite firm right out of the steamer.
4. Work in the white bean paste. While the dough is still warm, add the sweetened white bean paste (shiro an) in small spoonfuls and knead it in using food-safe gloves or a silicone spatula. Keep working until the paste is fully incorporated and the dough feels smooth and pliable.
5. Add the matcha. Sift the matcha powder directly onto the dough and knead until the color is uniform and a deep, even green. This takes 2 to 3 minutes of steady kneading. Wrap the dough in plastic wrap and let it rest at room temperature until completely cool, about 30 minutes.
6. Divide and flatten. Once cool, divide the matcha dough into 6 equal portions. Working with one piece at a time, flatten each ball into a round disc roughly 3 inches across, making the edges slightly thinner than the center.
7. Wrap the filling. Place one chilled red bean ball in the center of a dough disc. Gather the edges up and around it, pinching and smoothing as you go to seal completely. Roll gently between your palms to get a smooth ball with no seams showing.
8. Press and mold. Lightly dust a 50g mooncake mold with a little cooked mochiko flour (or plain mochiko). Place the mooncake seam side up into the mold. Press down firmly and evenly, then push the release lever to unmold. Place on a lined tray.
9. Chill before serving. Refrigerate the finished mooncakes uncovered for at least 30 minutes. This firms up the skin slightly and brings the flavors together. Serve cold alongside a cup of hot green tea.

What Are Snow Skin Mooncakes

Snow skin mooncakes are the lighter, no-bake cousin of traditional baked mooncakes. Instead of a pastry crust, the outer shell is made from cooked glutinous rice flour, giving it that tender, chewy, mochi-like texture. They became popular as a more modern alternative during Mid-Autumn Festival and are now found in countless flavor variations.

The biggest practical difference is that snow skin mooncakes don’t go in the oven at all. You steam the dough, let it cool, press it into a mold with your chosen filling, and chill. Start to finish is usually under an hour, which is a far cry from the full day some traditional mooncake recipes require.

Ingredients You Need and Why Each Matters

Mochiko flour (also sold as sweet rice flour or glutinous rice flour) is the backbone of the snow skin. It gives the dough that signature chew and soft stretch once steamed. Don’t swap it for regular rice flour or all-purpose flour; the texture simply won’t be the same.

Sweetened white bean paste (shiro an) gets kneaded into the cooked dough, adding a gentle sweetness and making the dough more workable. It also keeps the skin from drying out too quickly in the fridge. If you can’t find shiro an at an Asian grocery store, sweetened lotus paste is a reasonable substitute.

Matcha powder gives the dough its color and earthy flavor. Culinary grade works fine here and is more affordable, but if you have ceremonial grade matcha on hand, the color and taste will be noticeably more vibrant. Sift it before adding to avoid clumps in the dough.

Red bean neri yokan as the filling is a classic pairing with matcha. Yokan is a firm, sliceable red bean jelly, which makes it easier to portion and wrap compared to softer red bean pastes. You’ll find it in Japanese and Asian grocery stores.

Tips for Getting the Mold Pattern to Show Clearly

One of the most satisfying parts of making snow skin mooncakes is the moment you press the mold and get that crisp, detailed pattern on the surface. There are a few things that make the difference between a sharp imprint and a blurry one.

First, the dough needs to be fully cooled before molding. Warm dough is too soft and sticky; it’ll cling to the mold and lose definition when released. Second, dust the mold generously with cooked mochiko flour (not raw), tapping out any excess. If you don’t have pre-cooked mochiko, dry-fry a tablespoon in a pan over low heat for 3 to 4 minutes until it smells faintly nutty.

Press the mooncake firmly and steadily into the mold rather than jabbing repeatedly, and hold for about 5 seconds before releasing. Once unmolded, don’t move them around too much. Slide the tray straight into the fridge and let them set.

How To Store Matcha Snow Skin Mooncakes

These mooncakes are best stored in an airtight container lined with a sheet of parchment or paper towel. The paper helps absorb any condensation that builds up in the fridge, which can make the surface wet and cause the pattern to soften.

Kept this way in the refrigerator, they’ll stay good for up to 4 days. The skin does gradually firm up and dry out the longer they sit, so day one and two are when they’re at their best. For longer storage, you can freeze them in a single layer, then transfer to a bag or container. Thaw in the fridge overnight before serving.

Pro Tips

• Always use food-safe gloves when kneading the matcha dough. It stains fingers and nails deeply.
• If the dough feels too stiff after steaming, a tiny drop of neutral oil worked in by hand will loosen it up.
• For a more intense matcha flavor, add an extra half teaspoon of matcha powder. The white bean paste is sweet enough to balance even a stronger matcha.
• If using homemade red bean paste instead of yokan, freeze the paste balls for at least an hour before wrapping; soft paste is very hard to work with.
• This recipe makes 6 mooncakes with a 50g mold. Scale up proportionally for larger batches.
• Snow skin mooncakes are best served chilled, not at room temperature. Take them out of the fridge about 5 minutes before eating.

Recipe FAQs

Can I make these ahead of time?

Yes, and they’re actually better after a night in the fridge. Making them the day before you plan to serve them gives the flavors time to settle and the skin a chance to firm up to the right texture. Just store them in an airtight container with parchment underneath.

What can I use instead of red bean neri yokan for the filling?

Any firm, rollable filling works well. Taro paste, mung bean paste, sweetened lotus seed paste, or even a chilled dark chocolate ganache are all solid options. The key is that the filling should hold its shape when rolled into a ball; anything too soft or wet will be difficult to wrap.

Why is my mooncake skin sticking to the mold?

This usually comes down to two things: not enough flour in the mold, or dough that’s still slightly warm. Make sure the mold is well-dusted with cooked mochiko and that your dough has cooled completely to room temperature before you start pressing.

Can I freeze matcha snow skin mooncakes?

Freeze them in a single layer on a lined tray first, then transfer to a zip-lock bag. They keep well for up to 3 weeks. Thaw overnight in the fridge rather than at room temperature to prevent condensation from forming on the surface.
