I made these muffins out of the Woman's Day cook book The ABC of kids cooking.
Its not an allergy free recipe but it was easy to adjust it. I didn't follow the directions of sifting the flour and folding in. I put the bananas and all the other wet ingredients in the food processor until smooth then mixed in the flour and other ingredients adding the blueberry's last and just using the spoon to gently mix them in so they wouldn't squish, I used self-raising flour not plain like the recipe said. I used nuttelex instead of butter and 2 no eggs to replace the 2 eggs. Easy and the mixing up of the bananas with nuttelex and no egg has given me an idea I will test it out and share.
