1. Add all ingredients to blender starting with milk and ending with salt (through cinnamon if using). Blend until smooth – some oat pieces will remain whole which is okay. Remove blade from blender.
2. Heat large skillet over medium heat; once pan is hot add butter or oil.
3. Using 1/4 measuring cup, scoop batter and pour onto pre-heated skillet. Careful not to crowd. Cook pancake on on side until edges begin to bubble – about 3 minutes. Using large spatula gently flip and cook for 2 minutes. Repeat with remaining batter.
4. Transfer cooked pancakes to warmed oven before serving with your favorite toppings. Enjoy!
