Sweet Potato Tart
 
Makes 1 (9½-inch) tart
Ingredients
  • 1⅓ cups (202 grams) firmly packed finely crushed speculoos cookies* (about 26 cookies)
  • ¼ cup (57 grams) unsalted butter, melted
  • 1¼ teaspoons (2.5 grams) ground cinnamon, divided
  • ½ teaspoon kosher salt, divided
  • 5 ounces (142 grams) cream cheese, room temperature
  • 1¼ cups (295 grams) puréed cooked peeled sweet potato
  • ½ cup (110 grams) firmly packed light brown sugar
  • 2 teaspoons (6 grams) all-purpose flour
  • ¾ teaspoon (4.5 grams) vanilla bean paste
  • ½ teaspoon (1 gram) ground ginger
  • ⅛ teaspoon ground cloves
  • 2 large eggs (100 grams), room temperature
  • Vanilla Bean Meringue (recipe follows)
Instructions
  1. Preheat oven to 350°F (180°C). Spray a 9½-inch round fluted removable-bottom tart pan with baking spray with flour.
  2. In a large bowl, stir together crushed cookies, melted butter, ½ teaspoon (1 gram) cinnamon, and ¼ teaspoon salt until well combined; using a small straightsided measuring cup, press crumb mixture into bottom and up sides of prepared pan.
  3. Bake until set and fragrant, 8 to 10 minutes. Let cool completely on a wire rack. Reduce oven temperature to 325°F (170°C).
  4. In the bowl of a stand mixer fitted with the paddle attachment, beat cream cheese at medium speed until smooth and creamy, about 2 minutes, stopping to scrape sides of bowl. Add sweet potato, brown sugar, flour, vanilla bean paste, ginger, cloves, remaining ¾ teaspoon (1.5 grams) cinnamon, and remaining ¼ teaspoon salt; beat at medium-low speed just until combined. Increase mixer speed to medium, and beat until well combined, about 2 minutes, stopping to scrape sides of bowl. Add eggs, one at a time, beating until well combined after each addition and stopping to scrape sides of bowl. (Mixture will be on the thicker side.) Spoon into prepared crust; using a small offset spatula, spread into an even layer.
  5. Bake until top of filling is set and an instant-read thermometer inserted in center registers 155°F (68°C), 22 to 28 minutes. Let cool to room temperature in pan on a wire rack; cover and refrigerate for at least 8 hours or overnight.
  6. Carefully remove tart from pan; transfer to a serving plate. Spoon and spread Vanilla Bean Meringue onto tart as desired. Using a handheld kitchen torch, carefully brown meringue as desired. Serve immediately.
