Preheat oven to 400 degrees. In a large mixing bowl, beat butter, brown sugar, and sugar for 4 minutes until light and fluffy.
Add molasses and egg and mix for 1 minute longer.
Fold in flour, baking soda, cornstarch, salt, cinnamon, ginger, nutmeg, cloves, and chocolate chips.
Roll into 4-ounce, 5-ounce, or 6-ounce balls. Place on a parchment paper lined baking sheet. I prefer to use light-colored baking sheets.
Bake for 8-10 minutes. The cookies will still be slightly underdone when you remove them from the oven. Let the cookies sit for 10-15 minutes before moving them from the baking sheet.
