To begin making this delicious Frappuccino recipe, start by brewing your espresso, or strong-brewed coffee. Once it is brewed, set it aside so that it can cool.
Into the blender add the espresso or strong brewed coffee that has cooled. Also add in some of the crumbled Oreo cookies (remember to save a few for topping), chocolate chips, milk, mocha syrup, and optional vanilla. Blend these ingredients together.
Once the other ingredients are blended, add in as much ice as you desire. Keep in mind, the more ice you add to the drink, the thicker it will become. Blend the ice until it is smooth, and no chunks remain.
Pour the frozen coffee into your serving glass. For an extra burst of sweet goodness, add whipped cream, and a drizzle of chocolate syrup, and finish it off with a sprinkle of cookie crumbs. Then serve and enjoy!
