Browned Butter Sweet Potato Casserole

Directions

Preheat oven to 400 degrees. Pierce each sweet potato several times with a fork and transfer to a rimmed cookie sheet. Bake about 1 hour, or until very tender when pierced with a fork. Meanwhile melt 1/2 cup butter in a medium saucepan over medium heat and allow to brown, swirling pan occasionally. Remove potatoes from oven and reduce oven temperature to 350. Cut each in half and scoop out flesh into a large mixing bowl. Mash potatoes with a potato masher. Pour in 1/2 cup browned butter, using a rubber spatula to scrape excess butter from pan, add granulated sugar, 1/4 cup light-brown sugar and salt then using an electric hand mixer set on low speed, blend together until well combine. Add in eggs and mix until well blended, then pour in milk and mix until well blended. Pour mixture into a buttered 13 x 9 baking dish and spread into an even layer. Brown remaining 3 Tbsp butter in a saucepan. Pour crushed cornflakes into a mixing bowl, along with chopped pecans and 1/4 cup light-brown sugar and mix to combine. Pour browned butter over mixture and toss to evenly coat. Spread mixture into diagonal rows over mashed sweet potato mixture leaving about a 1 1/2-inch gap between rows. Bake in preheated oven for 30 minutes . Remove from oven and rest 5 minutes, then spread marshmallows between rows of corn flake topping. Return to oven and bake until marshmallows are melty and lightly golden if desired about 5 - 10 minutes. Serve warm.
