In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt and cinnamon.
In a medium bowl, whisk together ¾ cup of milk, the egg, and vanilla until well combined.
Pour the milk mixture into the flour mixture, then add the melted butter. Fold it all together just until combined. (The batter should be slightly lumpy.) Let it rest for 5 minutes while you preheat the griddle. (This helps to hydrate the whole wheat flour.) If you prefer a thinner pancake, stir in the extra ¼ cup of milk, 1 tablespoon at a time, until you reach your desired consistency.
Heat a large skillet or griddle over medium-high heat. Once hot, reduce to medium heat and rub or brush with butter to lightly grease the pan. Use a ¼ cup measuring cup to add pancake batter to the griddle.
Cook for about 3 minutes until golden on the bottom and bubbles start to appear on the top, then flip over and cook for 1 to 2 more minutes or until golden brown.
Serve the pancakes warm with butter, a drizzle of maple syrup, and fresh fruit, if you like.
