In a large bowl, combine the all-purpose flour, whole-wheat flour, baking powder, baking soda and salt. In a medium bowl, whisk together the eggs, buttermilk, skim milk, honey and vanilla extract. Fold the wet ingredients into the dry ingredients. The batter will look a bit lumpy.

Preheat a nonstick griddle over medium heat. Ladle the batter by the 1/3-cup-full onto the griddle. When the pancakes start bubbling, flip them to the other side cooking until golden brown.

Serve the pancakes with butter and maple syrup.
