I'm giving these ingredients by both weight and volume where relevant. Weighing is much easier, but if you don't have a digital kitchen scale yet* the volume measurements will do.
Ingredients:
14 oz milk chocolate (about 2 cups chips, or coarsely chopped bar) divided in half
3.5 oz (1/2 cup) butterscotch chips, divided in half

*No really, you should get a kitchen scale NOW! They're cheap, and make baking so much easier. You can
get an excellent scale from Amazon for about $25.
