Preheat oven to 350 f/155 c. Spray pan of choice with cooking spray. With a whisk, mix together all dry ingredients together in a bowl. Add all wet ingredients and mix to combine. Add half of the chopped chocolate and mix again. Pour into prepared pan and sprinkle remaining chocolate over the top. Bake about 45 minutes (more or less depending on the pan you choose) or til a toothpick inserted in the middle comes out clean. ENJOY!
