1. Preheat oven to 375° F and grease or line with muffin liners a standard 12 cup muffin tin.
2. Mix together wheat bran and buttermilk, let sit while preparing other ingredients.
3. In a large bowl, whisk together apple sauce, oil, egg, brown sugar, and vanilla. Add bran/buttermilk mixture.
4. Add flour, baking soda, baking powder, cinnamon, and salt. Stir until just combined**.
5. Spoon batter equally into muffin tin and bake for 15-20 minutes or until a tester (toothpick) comes out clean.

Muffins will last 5-7 days in an airtight container in the fridge.

** if you're a diehard raisin fan, here's where you would add 1/2 cup. Dried cranberries would also be yummy with a teaspoon of orange zest added in as well. Or, in the warmer months, Blueberries (fresh or frozen) would be a dream!

Note: Instead of buttermilk, one can use soured milk; simply add 1 tsp of lemon juice and top with milk to make 1 cup (250 ml) of buttermilk. Let sit for 5 minutes for the lemon juice (acid) to activate. This can also be done with swapping unsweetened soy or almond milk for the dairy milk.
