If you want to make a big batch of this multigrain mix, then combine 1 cup each of whole-wheat flour, oat flour, barley flour and ½cup of millet flour and rye flour. Use 1cup of this mix along with 1cup of wholewheat flour to make the pancakes. If not just follow the measurements for the flours given below. I was skeptical how the family would like the combination of different flours and the taste of buttermilk, but none of them seemed to notice anything. They were too busy enjoying these fluffy and delicious pancakes. They tasted amazing and I got a big thumbs up from both the kids 🙂
