Mochi buns are a type of bread with a chewy mochi filling. They can be found in Taiwanese bakeries and other Asian bakeries - that is, if you’re able to get there before they sell out. Oftentimes, mochi buns are baked with a sugar crust on top to add a buttery rich flavor and an additional crunchy texture. In one bite of the bun, you get three for one: airy soft bread, chewy mochi, and crunchy sugar crust. With this recipe, you won't need to worry about beating the crowd to get your fix of mochi buns; you'll instead be beating off the crowd that wants to sample some of yours!
