Preparation Phase

  1. Preheat your oven to 350°F (175°C) with the rack positioned in the middle.
  2. Line your 9×13 inch baking pan with parchment paper, leaving overhang on the sides.
  3. Bring all refrigerated ingredients to room temperature (approximately 30 minutes).

  • Mix until just combined
  • Avoid overmixing

Baking Process

Frequently Asked Questions

Q: Can I use regular rice flour instead of mochiko?
No, regular rice flour won’t produce the same chewy texture. Mochiko (sweet rice flour) is essential for authentic mochi texture.

Q: Why did my cake turn brown instead of green?
This usually happens when using low-quality matcha powder or baking at too high a temperature. Invest in good quality matcha and ensure your oven temperature is accurate.

Q: Can I make this recipe dairy-free?
Yes! Replace butter with coconut oil and whole milk with additional coconut milk. The texture will be slightly different but still delicious.

Q: How do I prevent my cake from being too dense?
Make sure all ingredients are at room temperature and don’t overmix the batter. Also, check that your baking powder is fresh.

Q: Can I halve the recipe?
Yes, use an 8×8 inch pan and reduce baking time to 45-50 minutes.

Recipe Variations

  • Black Sesame Swirl: Add a black sesame paste swirl before baking
  • Coconut Topped: Sprinkle shredded coconut on top before baking
  • Chocolate Chip: Add matcha-white chocolate chips to the batter
  • Red Bean: Layer sweet red bean paste in the middle
  • Yuzu: Add yuzu zest to the batter for citrus notes

Final Tips for Success

  • Always measure ingredients precisely
