Preheat your oven to 400 degrees F.

Line a muffin tin with 12 paper liners.

Stir together the oats and buttermilk, and let sit for about 5 minutes.

In a separate large bowl whisk together the flour, salt, soda and baking powder.

In another bowl combine the oil, egg and brown sugar. Then add this to the oat mix.

Then combine the oat mixture with the flour mixture.

Scoop the batter evenly between 12 muffin cups for 12 large muffins, or you if you want smaller muffins, spread the batter between 16 muffin cups.

Bake for 15 - 20 minutes.

Let the muffins cool in the muffin pan for about 5 minutes, then remove and let fully cool on a wire rack.
