Preheat oven to 325 degrees.
Combine dry ingredients in large bowl.
Mix wet ingredients in separate bowl, then add to dry ingredients and stir to combine. Stir in walnuts in chocolate chips.
Using a large cookie or ice cream scoop, drop the scones onto a baking sheet lined with parchment paper. Lightly wet hands and gently flatten the tops of the scones. They should be about 1 inch thick.
Bake 12-15 minutes until the scones are crisp outside and just cooked through. Do not over bake; the scones should be brownie-like inside.
