Notes
Moisture Retention: For moist and tender pumpkin muffins, avoid overmixing the batter. Mix until just combined and be careful not to overbake, which can lead to dryness.Texture Trick: For a moist and tender crumb, incorporate ingredients like grated cheese, diced vegetables (e.g., bell peppers, onions), or cooked bacon into the batter.
