Mix the flours, baking powder, baking soda, and salt in a bowl until combined. Whisk the buttermilk, eggs, butter, honey, and vanilla in a separate mixing bowl until well blended. Add the dry ingredients to the wet and stir until all the flour is mixed.

Using a pastry brush, lightly brush oil over the iron cooking surface, then pour the batter on the hot waffle iron (check manufacturer’s directions for recommended amount of batter) and close the lid. (If you're not sure about the amount, a good rule of thumb is to cover about 2/3 of the size of the waffle iron's cooking surface and adjust from there to avoid over-filling.) Let it bake on the iron 4 to 5 minutes or until steaming stops and the waffle is golden brown. Lift the lid to check color and continue to bake for another minute if needed.

Carefully remove the waffle with tongs or fork and serve. Repeat with the remaining batter. (Depending on the waffle iron, you may need to let it sit empty for 30 seconds between waffles to get nice and hot again.)

Top with soft butter, pure maple syrup, and fresh berries.
