Best of Both World Brookie Bars = Cookie Brownie Bars

• Preheat oven to 350ºF.

Brownie Dough:

• Place the sugar, butter, and cocoa in large, microwave-safe bowl and microwave in 20 second intervals until the butter is completely melted and stir together until smooth and creamy.
• Add the egg until completely incorporated.
• Stir in the vanilla extract, optional.
• Add the flour, baking powder, and salt, stirring together until smooth and set aside.

Chocolate Chip Cookie Dough:

• Melt the butter in a large microwave safe bowl for 30-45 seconds until melted. (If butter is too hot, let it cool just a bit).
• Stir in the sugars. Add vanilla and egg and mix well.
• Combine dry ingredients together and stir into the butter/sugar mixture and mix together.
• Stir in chocolate chips.
• Scoop Cookie dough (about 2 tbsp) into a parchment paper lined or sprayed with non-stick cooking spray prepared 9x13 pan, randomly in pam.
• Fill in the spaces with scoops of brownie dough. 
• Just keep adding scoops of each dough until finished using dough up. Smush the cookie dough and brownie scoops down so they touch each other. Add some extra chocolate chips on top and sprinkles if you want to make it more celebratory!
• Bake for 25-28 minutes. Remember it will continue to cook as it cools so be careful not to overbake. Check it at the 25 minute mark.
• Remove from oven and place on a cooing rack to finish cooling.
