Mini muffins are muffins that are smaller than traditional muffins. But, really though, mini muffins are 1/3 of the size of full size muffins. That means for a recipe that yields a dozen muffins, you'll get three dozen (36) mini muffins, give or take. So, if you're making a traditional recipe, you'll either need two mini muffin pans or you'll need to bake multiple batches.
