Scrub the outside of your sweet potatoes, and cook them until soft. I recommend cooking in the Instant Pot. See how here.
Preheat your oven to 400° F. Prepare an 8x8 baking pan by spraying with cooking spray.
Once your sweet potatoes are cooked and slightly cooled, scoop the orange inside in a large mixing bowl. Add the maple syrup, milk, vanilla, egg, cinnamon, nutmeg, and salt.
Beat with a hand mixer until smooth and there are no lumps. Spread the sweet potato mixture into your baking pan with a spatula until evenly smooth.
Oat Crumble
In a medium bowl, mix together the flour, oats, brown sugar, and pecans. Use a pastry cutter, danish dough whisk or a fork to mix in the melted butter until the mixture comes together.
Sprinkle the topping over your sweet potatoes. Bake for 25-30 minutes or until the top is a golden brown color and delightfully crunchy. Enjoy!
