Chewy, fudgy rich chocolatey brownie cookies get swirled with a spoon of pistachio butter and topped with shards and chunks of chocolate chunk halva. These brownie cookies crackle and shine just like a real brownie and have an irresistible chew to them! Once baked, they get showered with crushed pistachios and flaky sea salt. They are beautiful and delicious too! A must for your holiday cookie box.
