Banana and Chocolate Chip Muffins

備註

An all-in-one mixer method — everything goes into the bowl together, so the butter genuinely needs to be at room temperature. Quantities are the creator's own written list; the narration names the ingredients but no amounts.\n\nThe written list says 200 g dark chocolate while the narration talks about chocolate chips and says to use as many as you like — treat 200 g as a guide rather than a fixed amount, and hold some back for the tops.\n\nYield is not stated. The creator used small cases and notes it makes a lot; 12 is an estimate for standard muffin cases. She also corrects herself on camera: fill the cases two-thirds, not one-third.
