⅓ cup vegetable oil
⅔ cup lightly packed brown sugar
1 large egg
1 tsp vanilla
1 cup all purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
½ teaspoon salt

Meanwhile, in a small bowl whisk together flour, baking soda, baking powder and salt.
Whisk vegetable oil, brown sugar, egg and vanilla into bran/milk mixture.
Add dry ingredients to wet ingredients and stir until just combined.
