Makes:6 pop tarts
Nostalgia for dishes we loved as kids can be quelled when we taste them, years later, with our mature palates. Take Pop-Tarts or toaster tarts, for example. Found in the breakfast aisle of most grocery stores, these artificial sugar-licks taste like sweetened cardboard. But now you can relive those happy childhood breakfast memories minus the caramel color and Red Dye No. 40 by baking your own pop tarts. Fill them with real raspberry, blueberry, or cherry jam. Note: Eating one of our pop tarts is like eating a piece of pie for breakfast—it’s not exactly a balanced start to the morning, but it’s totally satisfying.
Game plan: You can make the dough a day in advance; just be sure to let it soften at room temperature for about 10 minutes before rolling out.
You can roll the dough scraps into 1 or 2 more tarts, but you’ll then need extra filling and glaze.
Though best when eaten fresh, the cooled pop tarts can be stored in an airtight container for up to 2 days at room temperature. Reheat them, if desired, in a 300°F oven on a baking sheet until hot, about 10 minutes. Freezing is not recommended.
1Whisk the flour, sugar, and salt in a large bowl until combined. Add the butter and toss with your fingers until well coated in the flour mixture. Using a pastry blender or your fingers, cut or rub the butter into the dry ingredients until reduced to pea-size pieces.
2Whisk the egg yolks and milk in a small bowl until combined. Add the egg-milk mixture to the flour mixture and mix with your hands until large clumps form. Turn the mixture out onto a work surface and knead briefly, smearing the butter into the dough with the heel of your palm until the dough completely comes together, about 1 minute.
3Divide the dough into 2 equal portions and shape into 2 (6-by-5-inch) rectangles. Wrap each tightly in plastic wrap and refrigerate at least 1 hour.
To assemble the tarts:
1Heat the oven to 375°F and arrange a rack in the middle. Line a baking sheet with parchment paper; set aside.
2Lightly dust a work surface with flour and roll 1 dough portion out into a rough 12-by-10-inch rectangle, rotating the dough and reflouring the surface and rolling pin often to prevent the dough from sticking. Using a pizza cutter or sharp knife, trim the dough to a 10-1/2-by-9-inch rectangle. Cut that into 6 equal rectangles (each about 3 1/2 inches wide by 4 1/2 inches tall). Using a flat spatula, transfer the rectangles to the prepared baking sheet, leaving about 2 inches of space between each. Place the baking sheet in the refrigerator.
3Whisk the egg and water in a small bowl until evenly combined; set aside.
4Roll out the second dough portion to the same dimensions as the first, trim, and cut into 6 rectangles. Using a fork, prick the dough all over.
5Remove the baking sheet from the refrigerator and brush a thin coating of the egg wash over each dough rectangle. Spoon 1 tablespoon plus 2 teaspoons of the jam onto each rectangle. Spread the jam into an even layer, leaving a 3/4-inch border.
6Place the pricked rectangles on top of the jam-covered rectangles. Press on the edges to adhere, and push down gently on the filling to slightly flatten. Using a fork dipped in flour, crimp the edges of the tarts. Bake until golden brown, about 23 to 25 minutes. Transfer to a wire rack and let cool completely before glazing.
For the glaze:
1Place all of the ingredients in a small bowl and whisk until evenly combined. (You may need to add more milk by the 1/2 teaspoon if the glaze is too thick.)
2Set the wire rack with the tarts on it over a baking sheet. Using a spoon, drizzle about 1 tablespoon of the glaze over each tart. Let set before eating, about 15 minutes.
