Ingredients

2 cups  all-purpose flour (spooned and leveled) 

1/4 cup packed brown sugar 

1 tablespoon baking powder 

1 teaspoon salt 

1/2 teaspoon ground cinnamon 

2 cups old-fashioned rolled oats 

2 cups milk 

2 large eggs 

1/4 cup vegetable oil, plus more for skillet 

Preparation

In a food processor, combine flour, sugar, baking powder, salt, cinnamon, and 1 cup oats and pulse a few times to coarsely grind oats. In a large bowl, whisk together milk, eggs, and oil. Add dry ingredients and 1 cup oats and whisk just until moistened.

Heat a large skillet (nonstick or cast-iron) or griddle over medium. Lightly oil skillet. Using 2 to 3 tablespoons for each pancake, drop batter in skillet and cook until a few bubbles have burst, 1 to 2 minutes. Flip pancakes and cook until browned on undersides, 1 to 2 minutes more. Repeat with more oil and batter.
