Apple Slice Traybake
 
Makes 8 to 12 servings
Ingredients
  • 1¼ cups (284 grams) unsalted butter, softened
  • 1½ cups (300 grams) plus 1 tablespoon (12 grams) caster sugar, divided
  • 4 large eggs (200 grams), room temperature
  • 1½ teaspoons (9 grams) vanilla bean paste
  • 3⅓ cups (417 grams) self-rising flour
  • ½ teaspoon (1 gram) ground cinnamon
  • ⅛ teaspoon ground allspice
  • 4 cups (440 grams) ¼-inch-sliced Honeycrisp apples
  • 1 tablespoon (15 grams) fresh lemon juice
  • 2 tablespoons (24 grams) turbinado sugar
  • Confectioners’ sugar, for dusting
  • Vanilla Custard Sauce (recipe follows)
Instructions
  1. Preheat oven to 350°F (180°C). Spray a light-colored 9-inch square baking pan with cooking spray; line pan with parchment paper, letting excess extend over sides of pan.
  2. In the bowl of a stand mixer fitted with the paddle attachment, beat butter and 1½ cups (300 grams) caster sugar at medium speed until well combined, about 2 minutes, stopping to scrape sides of bowl. Add eggs, one at a time, beating well after each addition. Beat in vanilla bean paste. (Mixture may look slightly curdled at this point, but batter will come together.)
  3. In a large bowl, whisk together flour, cinnamon, and allspice. With mixer on low speed, gradually add flour mixture to butter mixture, beating just until combined and stopping to scrape sides of bowl. Spread half of batter (about 596 grams) into prepared pan, smoothing into an even layer with the back of a spoon.
  4. In a large bowl, toss together apple slices, lemon juice, and remaining 1 tablespoon (12 grams) caster sugar. Arrange apple slices, flat side down, on top of batter. Top apple slices with remaining batter, spreading and swirling into an even layer with the back of a spoon. Sprinkle with turbinado sugar.
  5. Bake until a wooden pick inserted in center comes out clean and an instant-read thermometer inserted in center registers 200°F (93°C), 1 hour to 1 hour and 15 minutes, rotating pan and loosely covering with foil after 30 minutes of baking. Let cool in pan for 10 minutes. Using excess parchment as handles, remove from pan. Using a serrated knife, cut into pieces as desired. Dust with confectioners’ sugar, and serve warm with Vanilla Custard Sauce.
