You can either serve this over ice or blend it with ice and serve as a frozen cocktail.
These are the rocks directions: fill a large tropical or Collins glass with ice cubes. In a shaker, combine the coconut rum, butterscotch schnapps, hazelnut liqueur, pina colada mix and pineapple juice.
Shake vigorously and pour over ice in the glass.
If you blend it, use a little extra ice and add shredded coconut, if desired.
