Step 1 – Make the Mochi Dough

Instructions

1. Add glutinous rice flour into a bowl.
2. Add sugar.
3. Pour in milk.
4. Whisk until completely smooth.
5. Add butter.

There should be no lumps in the mixture.

Step 2 – Cook the Mochi

Microwave Method

• Microwave for 1 minute.
• Stir well.
• Microwave another minute.
• Stir again.
• Microwave for 30–60 seconds until thick and stretchy.

Stovetop Method

Cook over low heat while stirring continuously until it becomes thick, glossy, and stretchy.

Step 3 – Cool the Mochi

1. Dust the surface with cornstarch.
2. Transfer the hot mochi.
3. Wrap with plastic wrap touching the surface.
4. Let cool for 20–30 minutes.

Step 4 – Prepare the Puff Pastry

1. Thaw puff pastry according to package instructions.
2. Roll lightly to make it slightly thinner.
3. Cut into large triangles.

Each triangle will become one croissant.

Step 5 – Add the Mochi

1. Shape cooled mochi into small logs.
2. Place one log at the wide end of each triangle.
3. Roll tightly toward the tip.
4. Curve slightly into a crescent if desired.

Do not overfill or the mochi may leak during baking.

Step 6 – Prepare the Egg Wash

Beat together:

• 1 egg
• 1 tablespoon milk

Brush generously over each croissant.

Step 7 – Bake

Bake at:

• 400°F (200°C)
• 18–22 minutes

Bake until:

• Deep golden brown
• Crisp exterior
• Fully puffed

Step 8 – Cool

Allow the croissants to cool for 10–15 minutes.

The mochi inside remains very hot immediately after baking.

Step 9 – Decorate (Optional)

Choose your favorite finish:

• Dust with powdered sugar
• Sprinkle with matcha powder
• Drizzle melted chocolate
• Add sesame seeds

Serving Suggestions

Serve warm with:

• Coffee
• Milk
• Green tea
• Hot chocolate

Best enjoyed while the pastry is crisp and the mochi is still soft.

Storage

• Room temperature: 1 day
• Refrigerator: 3 days
• Freeze: Up to 1 month

To reheat:

• Oven: 350°F (175°C) for 5–7 minutes
• Avoid microwaving, as it softens the pastry.

Tips for Success

• Use glutinous rice flour, not regular rice flour.
• Keep the puff pastry cold until ready to use.
• Seal the pastry well around the mochi.
• Don't overfill the croissants.
• Cool on a wire rack to maintain crispness.
