Meanwhile, in a small bowl, whisk together the flour, brown sugar, baking powder, 1½ teaspoons cinnamon, and salt. In a large bowl, whisk together the eggs, milk, cider, and water. Add the dry ingredients to the wet and stir just until smooth. The consistency should be similar to pancake batter; if it’s too thick to drizzle, add some milk, a tablespoon at a time, until it reaches desired consistency.
