Blackberry Jam Bars
 
Makes 8 to 10 servings
Ingredients
  • 2 cups (454 grams) unsalted butter, softened
  • 2 cups (400 grams) granulated sugar
  • 4 large egg yolks (74 grams)
  • 2 teaspoons (8 grams) vanilla extract
  • 4 cups (500 grams) all-purpose flour
  • 2 teaspoons (10 grams) baking powder
  • ¼ teaspoon kosher salt
  • 1 cup Blackberry Jam (recipe follows)
  • ¼ cup (30 grams) confectioners’ sugar
Instructions
  1. In the bowl of a stand mixer fitted with the paddle attachment, beat butter and granulated sugar at medium speed until creamy, 3 to 4 minutes, stopping to scrape sides of bowl. Add egg yolks, one at a time, beating well after each addition. Beat in vanilla.
  2. In a large bowl, whisk together flour, baking powder, and salt. Reduce mixer speed to low. Gradually add flour mixture to butter mixture, beating just until combined. Divide dough into 4 pieces, and wrap in plastic wrap. Refrigerate for 1 hour.
  3. Preheat oven to 350°F (180°C). Line a 9x13-inch baking pan with parchment paper, letting excess extend over sides of pan. Spray pan with baking spray with flour.
  4. Grate 2 pieces of dough using the large holes of a box grater, and spread over bottom of prepared pan in an even layer. Press down gently. Freeze for 10 minutes. Grate remaining dough, and place on a baking sheet. Freeze for 10 minutes.
  5. Spread Blackberry Jam onto dough in prepared pan. Sprinkle remaining grated dough over Blackberry Jam in an even layer.
  6. Bake until golden brown and set, about 40 minutes, covering with foil to prevent excess browning, if necessary. Let cool for 10 minutes, and dust with confectioners’ sugar. Let cool completely. Using excess parchment as handles, remove from pan, and cut into bars. Dust with additional confectioners’ sugar, if desired. Freeze in an airtight container for up to 2 weeks.
