1 ½cupssemisweet chocolate chipsplus extra for topping dough
Instructions
Preheat oven to 375 degrees Fahrenheit. Cream together butter, both sugars, and eggs for 2 minutes until color starts to pale slightly.
Mix in cocoa powder, salt, cornstarch, and baking soda. Gradually add in flour (make sure your flour is measured correctly), mixing until just barely incorporated.
Stir in chocolate chips. Once you shape your cookies into balls, I like to stick some extra chocolate chips on the outside, its makes them prettier. I made my cookies pretty big (about 3-4 tablespoons of dough) and baked them for 9-12 minutes. If making smaller cookies bake them for 7-10 minutes. Bake them just until the outside starts form a crust.
Notes
If you find that your cookies are spreading too much or you prefer a thicker cookie, chill the dough before baking.
