Preheat oven to 400 degrees.
Line a baking sheet with a silicone baking mat or spray with nonstick cooking spray.
In a medium sized bowl, combine the whole wheat flour, oats, brown sugar, baking powder, and salt.
In a small bowl beat the eggs and olive oil into the buttermilk with a fork, until well combined. Stir the liquid mixture into the dry ingredients to make a crumbly dough. Knead in the bowl, 1-3 times until the dough forms a ball.
Turn the dough out onto the prepared baking sheet and pat into a 6 inch round that is about 1 inch thick. Using a sharp knife, cut the dough into 6 wedges.
Bake for 15 minutes or until the scones are lightly browned.
While the scones bake, beat the butter, maple syrup, and pumpkin pie spice together.
Serve scones warm with maple butter spread.
