Take the condensed milk, butterscotch chips, cinnamon chips and butter all together and add them to a saucepan.

Melt over a low heat until everything is melted and smooth. Next add one bottle of cream soda to your mixture.

Keep on heat and stir in the soda.

Once fully mixed, remove from heat and add in your second bottle of cream soda. Stir for about 10 seconds.

Add a scoop of vanilla ice cream into a mug then pour in your Butterbeer!
