Step 1: Preheat oven to 350 degrees f. Set oven rack to second-lowest position.
Step 2: Line 15 regular-size muffin tins with paper liners or spray with cooking spray.
Step 3: In a medium bowl combine the natural bran and the All-Bran with the buttermilk; allow to stand for 12-15 minutes, mixing a few times during that time (if the mix looks very dry then mix in a little more buttermilk).
Step 4: Meanwhile, in a medium bowl whisk egg, then add in oil and brown sugar, mix until very well combined. Mix in slightly mashed bananas.
Step 5: After the 15 minutes sitting time for the bran/buttermilk mixture, mix the sugar/banana mixture into the bran mixture.
Step 6: In a small bowl combine flour with next 5 dry ingredients. Mix in the raisins. Using a spoon or small spatula gently mix the flour mixture into the banana/bran mixture.
Step 7: Spoon the mixture between muffin tins filling almost to the top.
Step 8: Bake for 15-18 minutes or until a toothpick inserted into muffin comes out clean.
