In a large bowl, mix together the flour, oatmeal, sugar, salt, and baking powder.
In another bowl, break the egg and use a fork to beat it just a little bit. Then add the milk and vegetable oil, and mix.
Add egg mixture to the dry ingredients in the large bowl.
Using a mixing spoon, mix about 25 or 30 times. Don't mix too much! Your muffin mixture should be lumpy, not smooth.
Line a muffin tin with paper liners or lightly spray with nonstick spray. Spoon in the muffin mix. Fill each muffin cup about 2/3 of the way up.
When muffins are finished baking, remove from muffin tin and cool them on a wire rack.
Enjoy your berry tasty muffins!
