In large bowl measure in flour, oats, sugar, baking powder, baking soda, salt & chocolate chips.
Mix well and make a well in the center.
Pour liquids into the well in the dry ingredients.
Stir just to moisten. The batter will be a little lumpy. Fill greased muffin cups.
Bake at 400 degrees for 20 - 25 minutes. This makes 12 full muffins. I prefer them a little larger.
Here is the muffins all warm and toasty brown. By far the best recipe I have tried.
