All you pistachio lovers this is for you! Unlike many pistachio cookie recipes, this cookie is very chewy and spreads like sugar cookie. The cookie is loaded with pistachio flavor throughout. A touch of pistachio flour is added to the cookie dough base and toasty caramelized pistachio brittle gets folded in as well. Not enough pistachio? I got you. To add one more element of pistachio, I made some pistachio butter white chocolate shards and swirled that into the cookie dough. These cookies actually taste like pistachio and are so irresistibly chewy.
