*You can also melt the chocolate and butterscotch chips in the microwave if you prefer! Just place all the chips in a large microwaveable bowl and start by microwaving on high for about a minute. Stir and then continue to put the bowl back in the microwave, cooking at 30 second intervals and stirring in between each interval. As soon as all of the chips are mostly melted, just continue to stir until mixture is smooth. You do NOT want to cook the mixture too long!
