– Fast. Blend up this caffeinated creation in under 30 minutes--which can be less time than it takes to sit in a long drive-thru line. – Easy. Follow just a few easy steps to make a caramel frappuccino copycat and channel your inner barista. – Low Carb. Only net carbs per serving when you use some of my favorite keto approved syrups. – Budget-friendly. Cut your monthly coffee budget in half (or more) by skipping the nearby coffee chain and make your own version at home.
