Beat eggs in a mixing bowl. Add buttermilk, oil, flours, sugar, baking powder, baking soda, salt, and grated orange rind; whisk until smooth.
Heat a lightly oiled griddle until hot. Pour batter onto hot griddle forming desired size pancakes. Turn pancakes when bubbles form on top. Cook other side until golden. Serve hot with maple syrup and butter.
