Preheat oven to 400° F. Lightly grease standard size muffin cups.
Place oats and buttermilk in a bowl and stir to combine.
Add beaten eggs to that mixture and mix well with a spoon. Add brown sugar and oil to the mixture. Stir well, making sure that clumps of sugar are dissolved.
In a separate bowl sift the dry ingredients together. Turn the oatmeal mixture into the dry ingredients and stir only to dampen them. Do not over mix.
Bake for 20-25 minutes or until a light to medium golden brown. Turn baked muffins onto a wire rack and cool.Makes 12 Source:
