Butter Mochi, Explained
What is butter mochi?
Butter mochi is a chewy, golden-crusted Hawaiian dessert made with mochiko sweet rice flour, butter, coconut milk, sugar, and eggs. Unlike traditional Japanese mochi, it is baked rather than steamed or pounded, which gives it crisp caramelized edges and a dense, bouncy center. Pixlcat bakes butter mochi fresh daily in San Francisco and Boston.
What does butter mochi taste like?
Butter mochi tastes rich, buttery, and lightly sweet, with caramelized notes from its golden crust. Its texture is dense, chewy, and elastic, softer than traditional mochi and more springy than cake. Pixlcat offers flavors including Classic, Ube White Chocolate, Matcha, Chocolate, Black Sesame, S'more, and Breakfast.
Where can I buy butter mochi?
You can buy butter mochi at Pixlcat Coffee in San Francisco and Boston, and at the SF Ferry Building farmers market on Saturdays. For shipped butter mochi boxes and gifts, order through our Shopify store at pixlcatbuttermochi.com — currently shipping nationwide via UPS to the continental United States in 1–3 business days from the Boston kitchen.

Is butter mochi gluten-free?
Yes. Butter mochi is naturally gluten-free because it is made with mochiko rice flour instead of wheat flour. Pixlcat's butter mochi flavors are made without wheat flour and are built around the traditional chewy texture that makes butter mochi distinctive.
