What is butter mochi?

Butter mochi is a chewy Hawaiian dessert made with mochiko sweet rice flour, butter, coconut milk, sugar, and eggs. It is baked rather than steamed, giving it crisp edges and a dense, bouncy center.

What does butter mochi taste like?

Butter mochi tastes rich, buttery, and lightly sweet, with caramelized notes from its golden crust. Its texture is chewy, dense, and more elastic than cake.

Is butter mochi gluten-free?

Yes. Butter mochi is naturally gluten-free because it is made with mochiko rice flour instead of wheat flour.

What makes Pixlcat Butter Mochi different?

Pixlcat is the World's First Butter Mochi Café, built around fresh-baked butter mochi, specialty coffee, and matcha in San Francisco and Boston.

Is it Pixlcat or Pixel Cat Coffee?

Our official name is Pixlcat Coffee — no 'e' in Pixl. Some people know us as Pixel Cat Coffee, Pixelcat, or Pixel Cat Cafe. We're the same place! San Francisco's first butter mochi café, with locations on Clement Street in SF and in Charlestown, Boston.
