If you want to try this new way of eating, you can first order a McFlurry Oreo as usual, then order a topping of Hot Fudge chocolate sauce with the staff, and then ask the staff to drizzle the sauce directly into the McFlurry.
It’s worth mentioning that the Hot Fudge chocolate sauce is actually the same chocolate sauce used in the Chocolate Choco Dip, and now the topping is added to the McFlurry to bring the chocolate taste and deliciousness to a higher level.
