Brown Sugar Sweet Potato Pie
- 1 lb sweet potatoes (about 2 medium)
- 1/2 cup (115g) unsalted butter, softened to room temperature
- 1 cup (200g) packed light or dark brown sugar (I prefer dark)
- 1/2 (120ml) cup heavy cream
- 2 large eggs
- 2 Tablespoons all-purpose flour
- 1 teaspoon pure vanilla extract
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/4 teaspoon ground cloves
- 1/4 teaspoon ground ginger
- egg wash: 1 large egg beaten with 1 Tablespoon (15ml) milk
- Prepare a crust
- Place sweet potatoes in a large saucepan. Cover them with water, then bring to a boil on the stove top. Boil for 45-50 minutes, or until super soft. During this time, begin step 3.
- On a floured work surface, roll out one of the discs of chilled dough. Turn the dough about a quarter turn after every few rolls until you have a circle 12 inches in diameter. Carefully place the dough into a 9x2 inch pie dish. Tuck it in with your fingers, making sure it is smooth. Use a small paring knife to trim excess dough off the edges. Set aside.
- Preheat oven to 350°F (177°C).
- Drain the boiling water and run the potatoes under very cold water. The skin should peel off easily at this point. Allow to cool until easy to handle. Slice the potatoes into a couple large chunks, then place into a mixing bowl.
- Using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the potatoes on medium-high speed until smooth. Add the remaining ingredients (down to the egg wash, don't add that!) and beat on high speed until smooth and combined. Spread filling into prepared pie crust. Brush the edges of the crust with egg wash.
- Bake for 55-60 minutes or until the center of the pie is only slightly jiggly. A toothpick inserted into the center of the pie should come out *mostly* clean. After 30 minutes and if desired, place a pie crust shield on top of the pie to prevent the edges from over-browning.
- Place the pie on a cooling rack and allow to cool for at least 1 hour at room temperature before serving. The pie will slightly deflate as it cools; this is normal. Decorate with whipped cream or pie crust acorns (see note). Cover leftovers tightly and store in the refrigerator for up to 5 days.
