In a double boiler, melt the butterscotch and milk chocolate chips together. Stir until the mixture is nice and smooth. Add the peanuts and stir.
Immediately drop little blobs of the clusters onto a cookie sheet lined with waxed paper- using a spoon or a cookie scooper. Let them sit until the chocolate is set.
Notes
If you'd like, you can melt some extra butterscotch chips, spoon it into a little zip baggie, snip the corner and drizzle on top of the clusters.
