Soft milk mochi is a simple stovetop Japanese-inspired dessert made with glutinous rice flour, milk, and sugar for a chewy, silky bite. It sets in the fridge and can be coated with kinako, coconut, or starch for easy serving.
Adjust sugar to taste; add matcha or cocoa by sifting into the flour to avoid lumps. Keep heat medium-low and stir constantly to prevent clumps and toughness. For dairy-free, use full-fat coconut or oat milk and swap butter for neutral oil or vegan butter. Store covered at room temperature up to 6 hours, refrigerated 2–3 days with parchment between layers, or freeze pieces and thaw 20–30 minutes before serving.
