Ingredients

For The Sweet Potato Filling

  • 3 pounds sweet potatoes
  • 1/3 cup almond milk or skim milk
  • 1 large egg
  • 3 tablespoons pure maple syrup or honey
  • 1 tablespoon vanilla extract
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 1/2 teaspoons ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 2 tablespoons unsalted butter (or coconut oil) melted

For The Oat Crumble Topping

  • 3 tablespoons whole wheat flour
  • 1/4 cup old-fashioned oats
  • 3 tablespoons coconut sugar (or brown sugar)
  • 1/4 cup chopped pecans I used pecans
  • 1/4 teaspoon ground cinnamon
  • 2 tablespoons melted butter (or coconut oil)
  • 1 tablespoon honey or pure maple syrup

Instructions

Bake Sweet Potatoes

  • Preheat oven to 400 degrees F. Rinse and scrub potatoes to remove and excess dirt. Pat dry then poke holes all over each potato using a fork.
  • Wrap each potato in a piece of aluminum foil, then place on a baking sheet lined with parchment paper or foil.
  • Bake potatoes for 45-60 minutes or until they are completely cooked through. You can test this by inserting a fork or knife into the center of a potato.

How To Make Sweet Potato Filling

  • Reduce the oven temperature to 350 degrees F. Once the potatoes have cooled, peel off the skin and place potatoes in a large bowl. Beat together with an electric mixer, potato masher, food processor, or a large fork until is looks mashed and almost smooth.
  • Add the rest of the filling ingredients and continue to beat together until combined. The mixture should be smooth at this point.
  • Spray a 9x9 inch, 9x13 inch, or any casserole baking dish with nonstick cooking spray and pour in the filling. Spread with a spatula to create an even layer on top.

To Make The Oat Crumble Topping

  • Combine all of the oat crumble topping ingredients together in a medium bowl and mix until all of the ingredients are mixed together.
  • Sprinkle the crumble on top of the sweet potato filling and bake for 35-40 minutes or until the oat crumble is a light golden brown. Cool for a few minutes before serving. Enjoy!
