In a medium-sized bowl whisk together egg, oil, eggnog, and vanilla. In a separate bowl combine flour, salt, sugar, baking powder, and cinnamon. Add the dry ingredients into the wet ingredients and combine.
Preheat a skillet or griddle over medium heat. Spray with cooking spray and drop about ⅓ cup of the batter onto the warm skillet. Once it forms bubbles then flip to the other side and cook until golden brown.
