About your question making muffins from a loaf recipe. Quick bread recipes and muffin recipes are the same, and swapping the two can be fun. The oven temperature you asked is usually the same while the baking times are different. While most quick breads are baked about 45-60 min. in an average size pan, muffins are baked 15-20 minutes in general. Just keep checking your muffins starting at 15 minutes.
