These Muffins are high fiber and good for you. A good light breakfast or snack. The Batter needs to sit in Fridge 24 HOURS before using. My sister-in-law gave me this recipe. -On occasion I have substituted Ezekiel bran cereal with raisins instead of plain bran and I used lemon curd instead of orange marmalade. I have also used coconut oil in place of the veg oil, this will solidify quickly but it still turned out yummy. If you don't have buttermilk just mix 1 cup milk, 1 tsp vinegar/ or lemon juice wait 5 min. and now its buttermilk. This batter will last 30 days in fridge in case you don't need bake this all at once. My 2 year loves it when I make mini muffins that fit in her hand.
