This dish is a Thanksgiving tradition in my family- it just isn’t Thanksgiving without this sweet potato crunch! My mom found it online somewhere in the early days of the internet so we have no idea who Mamie is, but it is essentially a family recipe at this point.
It’s a pretty forgiving recipe, I once doubled the butter on accident and it was still delicious! (Although anything with extra butter tastes good).
Whether you want to double the butter or not, everyone at your Thanksgiving dinner will love this dish. So make it this year and start a new family tradition!
