Preheat oven to 350 degrees.  Line an 8 x 8 baking dish with foil and spray with non-stick spray.  Set aside.
In a medium bowl, add the sugar, flour, cocoa powder, salt, baking powder, and chocolate chips.  Be sure that the chocolate chips get coated with the mix.
In a small bowl, add the eggs, walnut oil, and vanilla.  Mix with a fork until well combined.
Pour the wet ingredients into the dry ingredients and mix with a spatula until just combined.
Pour into the prepared baking dish and bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
Let cool then slice.
Enjoy!
