Preheat the oven to 350°F, grease an 8-inch x 8-inch baking dish with butter or cooking spray.
In a 2 quart pot, warm baking chocolate and butter over medium heat, stirring until melted. Remove from heat and allow to cool slightly.
In a bowl, mix together chocolate and butter mixture, cane sugar, eggs, vanilla, and wheat flour until smooth and combined. Fold in nuts and chocolate chips.
Pour batter into the prepared baking dish. Bake 25-28 minutes, or until a tester comes out with fudgy crumbs.
