Ingredients

4 pounds sweet potatoes peeled and diced into ½ inch cubes
¾ cup brown sugar packed
¼ cup unsalted butter melted
2 teaspoons pumpkin pie spice
1 teaspoon ground cinnamon
1 teaspoon salt
1 teaspoon vanilla extract
1 ½ cups mini marshmallows
1 cup pecans whole

Instructions

Spray the slow cooker insert with non-stick spray.
Wash, peel, and cut sweet potatoes and add to slow cooker.
4 pounds sweet potatoes
In a medium bowl, whisk together the brown sugar, melted butter, spices, salt and vanilla.
¾ cup brown sugar, ¼ cup unsalted butter, 2 teaspoons pumpkin pie spice, 1 teaspoon ground cinnamon, 1 teaspoon salt, 1 teaspoon vanilla extract
Pour the butter mixture over the sweet potatoes and stir to combine.
Cover and cook on LOW for 7-8 hours or on HIGH for 3-4 hours or until sweet potatoes are fork tender.
Remove the lid and mash the potatoes.
Sprinkle the marshmallows evenly over the top and then replace the lid for 5-10 minutes allowing them to melt.
1 ½ cups mini marshmallows
Sprinkle with pecans and serve immediately.
1 cup pecans

Notes

To mash potatoes, I use a hand masher but you could also remove the potatoes from the slow cooker and use a hand mixer.
If you would like browned marshmallows, place insert of crock pot into oven at 375°F for 5-10 minutes, watching carefully just to brown.
If you don't have pumpkin pie spice, you can sub ¾ teaspoon cinnamon + ¼ teaspoon ginger.

Every slow cooker runs differently. Times given are a general recommendation and should be tested in your own slow cooker and adjusted as needed.
