I have to say, McDonald's soft serve is pretty good, it's soft but still holds together pretty well. Add bits and pieces of Reese's Peanut Butter Cups and it's dynamite!
I could really taste the chocolate and peanut butter much like if you opened a package of Reese's Peanut Butter Cups and tossed it with soft serve in a blender. The bits weren't frozen so they melted in your mouth. I have to say that room temperature Reese's blended in soft serve is so much better than ice cream with frozen peanut butter cups in it.

The Reese's McFlurry definitely has a leg up over Oreos and M&Ms. I highly recommend trying the Snack Size Reese's McFlurry if you are any fan of peanut butter cups. It's really too bad it's not a regular topping at McDonalds.
