When Carl started eating finger foods, we had a difficult time getting him to eat anything aside from grilled cheese and bananas. I tried out multiple toddler muffin recipes and eventually found one that he loves. The recipe is adapted from Allrecipes.com and is full of fruits and vegetables. I modified the recipe to decrease the amount of butter. Both all-purpose and white wheat flour work well in this recipe. I make them as mini-muffins so that I can use them for a quick breakfast or pull out one for a light snack. The best part is that they freeze perfectly so you can make a batch, freeze them, and use them for weeks to come (my favorite kind of recipes).
Carl is a picky eater and his face lights up when I pull out these muffins. In addition to the ingredients below, many people commenting on the recipe said they added dried fruit, zucchini, and other pureed vegetables. When making them the first time around I replaced half of the flour with rice cereal to provide extra iron (which was important for Carl because he was anemic). I would love to hear what modifications and additions you made to the recipe!
