Preheat the oven to 350 degrees F (180 degrees C).
In a mixing bowl, mix together the Granulated Sugar (1 cup) and Butter (1/2 cup). Then add in the Large Egg (2), Vanilla Extract (1 teaspoon), and Semi-Sweet Chocolate Chips (8 ounce), and combine everything well.
In a separate bowl, mix together the Unsweetened Cocoa Powder (2 tablespoon), All-Purpose Flour (3/4 cup), and Salt (1/4 teaspoon). Then add this mixture to the chocolate batter, and mix everything together.
Pour the batter into a baking dish, and bake for about 40 minutes.
Let cool before slicing.
