Instructions

Prepare the Shortbread Crust

  • Preheat oven to 350°F and line an 8×8 inch pan with parchment paper, leaving overhang for easy removal.
  • In a medium bowl, combine flour, cornstarch, sugar, salt, vanilla, and softened butter. Mix until a soft dough forms.
    1 cup all-purpose flour, 2 tablespoons cornstarch, 1/4 cup granulated sugar, 1/2 cup unsalted butter, 1/4 teaspoon salt, 1 teaspoon vanilla extract
  • Press dough evenly into the bottom of the pan and bake for 15–18 minutes, or until lightly golden.

Make the Sweet Potato Filling

  • Cook and peel your sweet potato. I baked mine in the oven at 400F for 55 minutes. Cut them into into chunks.
  • Add all filling ingredients (sweet potato, sugars, spices, cornstarch, vanilla, and milk) to the blender.
    1 & 3/4 cup cooked sweet potato, 12 oz evaporated milk, 1/2 cup packed brown sugar, 1/4 cup granulated sugar, 1 teaspoon vanilla extract, 2 teaspoon cornstarch, 1& 1/2 teaspoons ground cinnamon, 1/2 teaspoon ground ginger, 1/4 teaspoon ground nutmeg, 1/4 teaspoon ground allspice, 1/8 teaspoon ground cloves, 1/2 teaspoon salt
  • Pulse or blend until smooth and fully combined. Add in the eggs and the egg yolk last and pulse a few more times to get everything incorporated.
    2 large eggs, 1 egg yolk

Assemble and Bake

  • Pour the sweet potato filling over the hot pre-baked shortbread crust.
  • Bake for 30-37 minutes, or until the edges are set and the center is slightly jiggly. A toothpick inserted should come out mostly clean. Start checking at around 30 minutes then every 2 minutes after that

Cool and Serve

  • Allow bars to cool completely, then chill in the fridge for at least 2 hours to set.
  • Lift the bars out using the parchment paper, cut into squares, and serve with whipped cream if desired.
