Daifuku (Sweet Filled Mochi)

Pin it

Introduction

Daifuku are soft, pillowy mochi balls filled with sweet red bean paste—they take about 30 minutes total and require just a microwave and basic kitchen tools. The dough comes together in two quick microwave bursts, then you shape it around marble-sized anko balls to create a delicate, chewy exterior that contrasts perfectly with the creamy filling.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 5 minutes
• Total Time: 20 minutes
• Servings: 12

Ingredients

• Anko filling
• ~½ cup potato starch (katakuriko)
• 1 cup sweet glutinous rice flour (mochiko)
• ⅔ cup water
• ¼ cup white granulated sugar

Instructions

1. Prepare anko filling as directed. Shape into 12 small, marble-sized balls and set aside.
2. Prepare a smooth surface, such as a cutting board, by coating with potato starch; be generous, as the dough will be very sticky.
3. Heat water and sugar together in a microwave until sugar is dissolved. Add rice flour and stir completely. Microwave for 2 minutes, remove and stir. Microwave for 2 more minutes, or until dough begins to expand. Remove from microwave, stir again, and remove the dough to the potato starch-coated surface. The dough, called mochi, will be very hot.
4. Spread or roll the mochi dough out until thin. Using a knife, cut into 12 even sized pieces.
5. Coat the palms and fingers of your hands in potato starch. Spread each piece out as thin as possible.
6. Place an anko ball in the middle of each mochi piece, then wrap the mochi around the ball, forming a bigger ball.
7. Roll shaped daifuku in potato starch, and set on a plate dusted with potato starch or a piece of wax paper.
8. Serve warm or cool. Store in an airtight container. Very perishable.

Variations

Matcha daifuku: Reserve 2 tablespoons of the mochiko and mix it with 1 tablespoon matcha powder and 1 tablespoon sugar before adding to the water. This creates a pale green dough with a subtle earthy flavor that pairs well with red bean or white miso filling.

Strawberry daifuku: Place a whole fresh strawberry in the center of each mochi piece instead of anko, then wrap as directed. The strawberry provides a bright, tart contrast to the soft sweetness of the mochi.

Sesame-anko daifuku: Toast 3 tablespoons of sesame seeds and fold them into the mochi dough just before shaping. The nuttiness complements the red bean filling without overwhelming it.

Coconut-dusted daifuku: Instead of rolling the finished daifuku in potato starch, roll them in unsweetened shredded coconut for a textural change and a hint of tropical flavor.

Tips for Success

Keep your hands heavily dusted with potato starch. The mochi dough is extremely sticky when warm, and a generous coating on your palms and fingers prevents sticking and makes shaping much easier.

Work quickly after removing the dough from the microwave. The mochi becomes easier to handle as it cools slightly, but if it cools too much, it becomes difficult to spread and wrap. Aim to shape all 12 within 5–10 minutes of removal.

Spread each mochi piece as thin as possible before wrapping. Thinner pieces create the signature delicate, chewy texture; thick pieces will feel doughy rather than light.

Use a sharp knife to cut the dough into 12 even pieces. Wet the knife lightly between cuts to prevent sticking and ensure clean edges.

Storage and Reheating

FAQ

Can I prepare the anko filling ahead of time?

Yes. Make or buy anko filling up to 3 days in advance and store it in an airtight container in the refrigerator. Let it come to room temperature and shape it into balls just before you begin making the mochi dough.

What if my mochi dough is too thick or stiff after microwaving?

This usually means the dough needs a few extra seconds of heat. Microwave it in 30-second bursts, stirring between each, until it reaches a soft, spreadable consistency that holds together but isn’t lumpy.

Can I use a different filling instead of anko?

Yes. Sweetened chestnut paste, sweetened black sesame paste, or even a small spoonful of chocolate ganache work well. Keep the filling amount similar to the anko balls so the proportions stay balanced.

Why do my daifuku crack when I wrap them?

The mochi is likely too cool and has stiffened, making it brittle. Work faster and wrap each piece while the dough is still warm and pliable. If the dough cools completely, microwave the batch for 20–30 seconds to soften it again.
