1 1/2 cups wheat bran
1 cup buttermilk
1/3 cup vegetable oil I also decrease the oil by half and sub Greek yogurt for the rest.
2/3 cup brown sugar
1/2 teaspoon vanilla extract
1 cup all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
1/2 teaspoon salt
1/2 cup raisins can also add chocolate chips.
1. Preheat oven to 375 degrees F (190 degrees C). Grease muffin cups or line with paper muffin liners.
2. Mix together wheat bran and buttermilk; let stand for 10 minutes.
3. Beat together oil, egg, sugar and vanilla and add to buttermilk/bran mixture. Sift together flour, baking soda, baking powder and salt. Stir flour mixture into buttermilk mixture, until just blended. Fold in raisins and spoon batter into prepared muffin tins.
4. Bake for 15 to 20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
This recipe is also pretty to add mix ins like zucchini, carrot, banana, oatmeal. I would probably do between a cup and 2 cups of a add in.
