Measure all dry ingredients into a large bowl: all purpose flour, oats, baking powder, baking soda, cinnamon, sugar and salt. Whisk to combine.
Create a well in the center of the dry ingredients for all the remaining wet ingredients.
Whisk to combine and create a mostly smooth batter (with the exception of the oats which will make it seem a little lumpy, but thats normal.)
Preheat a nonstick skillet over medium to medium-low heat. Add butter or nonstick cooking spray to the hot pan. Using a 1/4 cup measure, pour batter onto hot griddle and spread into circles. Cook until lightly browned and golden, then flip and cook other side. Remove cooked pancakes from pan.
