Ingredients

For the sweet potato layer

  • 2 lbs sweet potatoes
  • 3 tablespoons butter melted
  • 1/4 cup milk
  • 1/4 cup brown sugar
  • 2 tablespoons maple syrup
  • 1 teaspoon cinnamon
  • 1 egg
  • 1/2 teaspoon vanilla extract
  • cooking spray

For the streusel

  • 3/4 cup brown sugar
  • 1/2 cup flour
  • 5 tablespoons melted butter
  • 3/4 cup chopped pecans

Instructions

  • Preheat the oven to 350 degrees. Line a sheet pan with foil and coat with cooking spray. Prick the sweet potatoes with a fork and place them on the pan in a single layer.
  • Bake the potatoes until tender, 45 minutes to an hour.
  • When the potatoes are cool enough to handle, cut them open, scoop out the insides and place the sweet potatoes in a large bowl.
  • Add the 3 tablespoons of melted butter, milk, brown sugar, maple syrup, cinnamon, egg and vanilla to the bowl.
  • Use a potato masher or hand mixer to mash or beat the sweet potatoes until mostly smooth.
  • Coat a 9 inch square pan or 2 quart baking dish with cooking spray.
  • Spread the sweet potato mixture in an even layer in the pan.
  • In another bowl, mix together the brown sugar, flour, melted butter and pecans until large crumbs form. Sprinkle the crumb topping over the sweet potatoes.
  • Bake for 30 minutes or until topping is lightly browned.
  • Let sit for 10 minutes, then serve.
