Mochi donuts, also known as poi mochi, are a fusion pastry that combines traditional American doughnuts and Japanese mochi. They are made from glutinous rice flour or tapioca flour and are most commonly shaped into eight small balls connected into a circular shape that is easy to pull apart. Mochi donuts have a fluffy and moist texture with a satisfying chew. They are often found in various flavors and colors, with classic buttery vanilla dough being the most common. Glazes that feature Japanese flavors like matcha, pandan, and ube are also common. Mochi donuts can be garnished with different toppings such as chocolate chips, sesame seeds, grilled coconut chips, fresh or candied fruit, sprinkled with matcha powder, or cinnamon sugar.

Mochi donuts are naturally gluten-free and have become popular in the United States in recent years, encouraged by social media. They are often presented in donut form, which makes them more accessible to people who have never tasted mochi before. Mochi donuts can be found in various bakeries and shops across the United States, and they are also easy to make at home using mochiko flour (a Japanese glutinous short-grain rice flour), tapioca starch, and other ingredients like sugar.
