Sweet Potato Casserole with Marshmallows and Streusel
Sweet Potato Casserole with Marshmallows and Streusel. A classic Thanksgiving side dish with savory and creamy sweet potatoes topped with toasted marshmallows and brown sugar streusel.
Bake the sweet potatoes until tender -- about 45 minutes at 400 degrees. They need to be fork tender all the way through the middle. They may need to cook up to 1 hour or so depending on how large the sweet potatoes are.
Scoop out the inside of the cooked sweet potato and place in a mixing bowl. Add the butter, brown sugar, vanilla, real maple syrup, egg, milk, and cinnamon and whip until smooth and creamy.
In a small bowl, stir together butter, brown sugar, and flour.
Preheat oven to 350 degrees. In a 9 x 9 baking pan, spread mashed sweet potatoes all over the bottom of the pan. Top with brown sugar streusel.
Bake for 28-32 minutes. Once it is baked and bubbly, sprinkle on the mini marshmallows and bake until it is nice and toasted about 4-5 more minutes. If you want them extra toasty, place under broiler for 1-2 minutes, watching carefully the entire time to prevent burning.
Serve immediately.
