Q: What is daifuku mochi?

Daifuku is a traditional Japanese confection — a small round mochi (made from glutinous sweet rice flour) wrapped around a sweet filling. The most classic version is filled with red bean paste, but black sesame, fruit, and ice cream daifuku are all wildly popular variations.

Q: Why do you steam the mochi instead of microwaving it?

Steaming in a 9-inch pie pan gives you the perfect thickness automatically — no rolling out sticky dough, no guesswork. Microwaving works in a pinch, but steaming gives a more even, traditional texture and zero hot spots.

Q: Can I use cornstarch instead of potato starch for dusting?

Technically yes, but I don’t recommend it. Cornstarch isn’t safe to eat raw, and since the dusting stays on the finished mochi, you’ll be eating it. Potato starch is safe raw and gives that classic silky daifuku finish.

Q: How long does daifuku mochi stay fresh?

This mochi stays soft and pliable for several days at room temperature, kept in an airtight container. (That said, they rarely last that long around my house.)

Q: Can I refrigerate daifuku mochi?

It’s best to avoid the fridge — cold temperatures make mochi hard and lose that signature chewy texture. Store at room temperature in an airtight container instead.

Q: What’s the trick to handling sticky mochi dough?

Two words: cool and dust . Let the steamed mochi cool for at least 15 minutes before handling, and keep your work surface (and hands!) lightly dusted with potato starch. Hot mochi = sticky chaos.

Q: What other fillings can I use?

Almost anything! Try sweetened red bean paste (anko), fresh strawberries, mango, peanut butter, Nutella, matcha white chocolate ganache, or even a small scoop of ice cream for mochi ice cream.

Q: Is sweet rice flour the same as regular rice flour?

Nope! Sweet rice flour (also called glutinous rice flour or mochiko ) is made from short-grain glutinous rice and is what gives mochi its signature chewy, stretchy texture. Regular rice flour will not work — your mochi will be crumbly and sad.

Q: How many daifuku does this recipe make?

Using a 3-inch round cookie cutter, you’ll get 6 to 7 daifuku per batch. The scraps press easily back together to form that final circle, so nothing goes to waste.

Q: Can I make the black sesame paste from scratch?

Absolutely — and I highly recommend it. My homemade black sesame paste recipe is linked here , and it’s thick enough to roll into little balls, which makes wrapping these daifuku a breeze.

Chewy, pillowy mochi wrapped around a rich black sesame filling — this Daifuku Mochi is dangerously addictive, not too sweet, and easier to make at home than you’d guess. Steamed in a 9-inch cake pan for the perfect thickness, no rolling required. See notes if you are using an 8-inch cake pan.

Ingredients

Units Scale

3/4 cup (100 grams) glutinous rice flour/sweet rice flour
1/4 cup (50 grams) granulated sugar
3/4 cups (180 grams) water
1 teaspoon of neutral oil (canola, vegetable, grapeseed)
1/8 cup of potato starch, for dusting
1/3 cup (80 grams) black sesame paste (recipe here)

Instructions

In a large steamer pot, fill about 2 inches of water and insert a steam rack. Heat the water to a boil.
In a medium mixing bowl, combine the sweet rice flour, sugar and water. Whisk until combined.
Grease and line a 9 inch cake pan with oil. Pour the sweet rice batter into the cake pan.
Place the cake pan into your steamer pot. Cover and cook for 15 minutes. When done, be careful when lifting the lid to prevent water from dripping on to the mochi. Remove the cake pan and place it on a cooling rack to cool for at least 15 minutes. This will allow the mochi to set. Even if it is cool to the touch, the mochi is too sticky to handle unless it is completely cooled for at least 15 minutes.
Prepare a work surface for wrapping the mochi. Lightly dust the work surface with potato starch. Lift the cooled round sheet of mochi on to your work surface, leaving the parchment paper attached on the bottom. When completely cooled, the mochi will be very easy to separate from the parchment.
With a 3 inch wide cookie cutter, align it on the edge of the round mochi and press down to cut a circle. You may need to shimmy the cutter a little bit but it should cut through the mochi and gently separate your 3 inch circle from the rest of the mochi sheet. Place your circle of a potato starch dusted section. Using 2 teaspoons of sesame paste, gently press the paste into a round ball and place that on the center of your dough circle. Pull opposite sides of the circle up and together, pinch to seal. Roll it gently over all sides of the mochi ball on a potato starch dusted section to smooth out the ball. Use more potato starch if need and then tap off the excess.
Repeat with more circles using the rest of your mochi sheet. Press together the scraps to make your last circle. The potato starch will help keep your daifuku mochi getting sticky. Enjoy within 3 days. You mochi will stay soft.

Notes

If using an 8-inch cake pan, you would have to scale the recipe so that the mochi is cooked to the same thickness. Let’s put our math hats on!

The Quick Math:

9-inch pan area: π × 4.5² ≈ 63.6 sq inches
8-inch pan area: π × 4² ≈ 50.3 sq inches
Scaling factor: 50.3 ÷ 63.6 ≈ 0.79 (roughly 79% of the original)

Your 8-inch Pan Amounts:

Ingredient	9-inch Pan	8-inch Pan
Sweet rice flour	100 g	79 g
Granulated sugar	50 g	40 g
Water	180 g	142 g
