2In a large bowl, mix together the flour, oatmeal, sugar, salt, and baking powder. Mix in blueberries.
3In 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 this mixture to the first mixture 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.
4Line a muffin tin with paper liners or lightly spray with nonstick spray. Spoon in the muffin mix. Fill each muffin cup about two thirds of the way up. Bake for about 20 minutes. When muffins are finished baking, remove from muffin tin and cool them on a wire rack.
