Another old recipe I decided to revisit.
I don't like Hazelnut vapes so I simply removed it and
bumped up the RY4 Double. (I also made some other minor changes that I can't remember) The result is absolutely delicious.
I have no doubt though that the original recipe is fantastic as well.
@DIYSquonker, the brown sugar adds a small bit of sweetness, but it's mostly provides support for the butterscotch. And I find that this recipe doesn't need additional sweetener, but I would suggest maybe 0.25% to 0.5% on the super sweet.
