In a large mixing bowl, whisk together all-purpose flour, cornmeal, sugar, baking powder, salt, cumin, and cayenne pepper. In another large mixing bowl, whisk milk, maple syrup, eggs, and apple cider vinegar. When egg and milk are completely integrated, whisk in finely chopped cilantro. Pour wet ingredients into dry, gently incorporating with a whisk until no large clumps remain. Add in grated cheddar cheese and use whisk to combine.
