Frequently Asked Questions

Can I make this ahead of time?
Yes! Assemble everything except the marshmallows and refrigerate overnight. Add marshmallows just before baking.

What’s the difference between sweet potatoes and yams?
In the U.S., “yams” usually refer to soft orange-fleshed sweet potatoes. True yams are starchy and white—we’re using the sweet potato kind here.

Swap them out for a brown sugar streusel topping or simply increase the pecans.
