Butterscotch pudding gets an autumnal makeover with the addition of pumpkin puree and a fluffy, spiced whipped cream topping. This is my pumpkin-butterscotch custard with spiced whipped cream. It's like the butterscotch pudding of your dreams with autumnal spices. The first thing you want to do is make a caramel. It may smell a little burnt, but that's OK. Add the remaining cream and milk, stirring until the sugar dissolves.
