Useful approach: They can share flavours but are built by different processes.
Muffins
Usually chemically leavened and baked in cups, with a quick-bread or cake-like crumb.
Doughnuts
May be yeasted or cake-style and are commonly fried, though baked versions exist. Glazes and fillings are central to many styles.
Fair comparison
Compare freshness, portion, filling and purpose. A doughnut should not be penalized for lacking a muffin crumb, or vice versa.
Practical checklist
- Compare items by method and purpose.
- Check perishable fillings and storage instructions.
- Avoid assuming a category name guarantees ingredients.
- Use current bakery information.
