- 2 1/4 cups rolled oats
- 2 1/2 cups buttermilk
- 1 1/2 cups all-purpose flour
- 3/4 cup whole wheat flour
- 1/3 cup white sugar
- 1 1/2 teaspoons baking powder
- 1 1/2 teaspoons baking soda
- 3/4 teaspoon salt
- 3/4 teaspoon ground cinnamon
- 3 eggs
- 3/4 cup milk, or more as needed
- Mix the rolled oats and buttermilk together in a large bowl; allow to soak 15 minutes.
- Whisk the all-purpose flour, whole wheat flour, sugar, baking powder, baking soda, and salt together in a separate large bowl.
- Beat the eggs and milk together in a separate small bowl; mix into the soaked oats. Stir the flour mixture into the oat mixture. If the batter seems dry, add milk about 1 tablespoon at a time until the desired consistency is achieved.
- Grease a skillet or griddle and place over medium heat. Ladle about 1/2 cup of batter per pancake onto your preheated cooking surface. Cook until the pancake is lightly golden brown, about 2 minutes, flip, and continue cooking to brown other side, another 1-2 minutes.
