One of the most useful things Alton Brown ever taught me was how to recognize a Muffin. A Muffin recipe, that is. Alton breaks out baking recipes into several main categories, of which The Muffin is one. One key characteristic of a Muffin recipe is that it uses liquid fat, such as oil or melted butter, instead of solid fat, such as butter or shortening. This means that Muffin recipes are easy to mix, since they don’t require more elaborate methods of working in the fat, such as creaming (like a cake) or cutting (like biscuits or pie crust).
If your recipe calls for mixing together dry ingredients (flour, baking powder, salt, and such), wet ingredients (egg, milk, vanilla, and such) and then combining the two, it might very well be a Muffin. In fact, whenever I suspect that a recipe is a Muffin, I know that it will work just fine using this method of combining, regardless of what the recipe calls for.
For example, when making a cake, it is typical to cream together the sugar and butter, then add the eggs, one at a time. The purpose for adding the eggs slowly is to allow them to evenly distribute themselves throughout the butter-sugar mixture with minimal disturbance of the tiny air pockets that the sugar crystals have cut into the butter. Because the flour has not yet been added at the time the eggs are mixed in, gluten formation is not yet a consideration. With Muffins, however, the flour is in the bowl from the beginning, and so as soon as any liquid gets in there, gluten will start forming, making the resulting baked good tough and rubbery, instead of tender. This means that you want to keep the mixing to the absolute minimum necessary to combine the ingredients so as to minimize gluten formation. So, if a Muffin recipe tells me to stir in the milk, then the oil, then the eggs, then the vanilla, I’m going to tell it to go to hell and pre-mix all of those ingredients in a separate bowl before stirring them as efficiently as possible into the pre-mixed dry goods.
This is one advantage of being able to recognize Muffin recipes when you see them.
Muffin recipes are more common than you might think, because Muffins can actually be made in many different shapes other than the usual Muffin tin. Pancakes, for example, are just flat, griddle-cooked Muffins. Carrot-cake, despite its name, is also usually made with a Muffin-class recipe. Likewise banana bread and other fruit-based quick-breads. Unlike cake recipes, which are tailored to a certain size and shape of pan, and which may not work well if switched to a radically different type of pan, Muffins are very versatile. There should not be any problem switching a banana bread recipe from a 9×5 bread pan over to a standard muffin tin. You could even make pancake muffins if you wanted to, although I’m not sure why you would.
As a final caveat, Muffin recipes all use chemical leavening such as baking powder or baking soda. If your recipe uses yeast, it’s probably a yeast-bread recipe, in which case there are most likely many other steps in the recipe that will distinguish it from Muffins. That being said, I did once see a recipe for Amish Friendship Bread that included both baking powder and yeast, and that came together very much like a quickbread (or Muffin), so I guess there’s an exception to every rule.
