Fall has arrived...... Oranges are my favorite this season... I love oranges....I know you love them too.... I love orange juice in cakes........check out my favorite orange cake recipe here These muffins are soft, light, and have two of my favorite things.......orange and chocolate chips....WOW! They are not dense like cappuccino muffins ....they are airy and pillow like.....I think the buttermilk and the orange juice gave that soft texture to the muffins. Plus these muffins can be easy whipped up.... If you do not have buttermilk please don't think of not baking these oh! so! feather light muffins....you can make buttermilk substitute right in your kitchen and get along with your baking. *Buttermilk substitute to make 1 cup of buttermilk : In your measuring cup pour 1 tbsp lemon juice or 1 tbsp white vinegar and then add low fat milk ( if you are calorie conscious) to fill the cup. Let it stand for 5 min to curdle.....that's it buttermilk
