recipe from Lisa@The Cutting Edge of Ordinary
¾ cup softened butter (12 tablespoons)
3 ounces cream cheese, softened
1½ cups packed brown sugar
½ cup granulated sugar
3 tsp vanilla
3½ cups all-purpose flour
3 tsp cornstarch
1½ tsp baking soda
½ tsp course sea salt or ¾ tsp regular salt
2 cups semi-sweet chocolate chips
Preheat oven to 350 degrees
Spray a large cookie sheet 15''x11'' (half sheet tray) with cooking spray and set aside. With your stand mixer or a hand mixer, cream together the butter, softened cream cheese, brown sugar and granulated sugar until well combined. Add the eggs and vanilla and continue mixing for 3 minutes or until mixture is very light and fluffy. Scrape sides down halfway through mixing.
Add the flour, corn starch, baking soda, and salt and mix until well combined. Add chocolate chips and mix or stir until combined. Scoop mixture out evenly over baking sheet. The batter is thick so it helps to drop the dough in increments over the pan and then spread it.
Bake at 350 degrees for 15 - 20 minutes. Place cookie sheet on cooling rack and allow cookie bars to cool completely. You can put them in the fridge to speed up this process if desired. You can eat them warm but they are much easier and less crumby and messy if allowed to cool completely.
