Equipment

Ingredients

Crust

  • 1 cup water with ice
  • 1 tablespoon apple cider vinegar
  • 2 ½ cups all purpose flour 300g
  • ½ teaspoon sea salt
  • 1 cup butter cold
  • 1 large egg
  • 1 tablespoon milk or water
  • 2 tablespoons coarse sugar

Filling

  • 2 cups blueberries fresh or frozen
  • ¼ cup granulated sugar
  • 1-2 tablespoons lemon juice from 1 lemon
  • 1 tablespoon cornstarch or flour
  • ½ teaspoon ground cinnamon
  • 2 tablespoons water

Glaze

  • 1 cup powdered sugar
  • 1-3 tablespoons heavy whipping cream

Instructions

Crust

  • Combine ice water and apple cider vinegar, set aside for later.
    1 cup water with ice, 1 tablespoon apple cider vinegar
  • Into a large bowl, sift flour and salt. Mix until combined. Add cold butter (cut into small cubes), and mix until all the cubes are covered in flour.
    2 ½ cups all purpose flour, ½ teaspoon sea salt, 1 cup butter
  • Use a pastry cutter, knife, or food processor to mix in the flour until it resembles coarse breadcrumbs with some larger pieces. Work quickly so the butter doesn’t melt.
  • Add a few tablespoons of ice water and vinegar mixture to the flour and butter. Mix until distributed. Add vinegar water a tablespoon at a time, mixing just until a dough forms if you pack the mixture tightly.
  • Using your hands and working quickly, combine the mixture to form a dough, packing it tightly into a ball. Squish to flatten and fold in half. Repeat. Cut the dough to divide in half and roughly form each half into a square. Wrap with wax paper or cling wrap and refrigerate for at least 45 minutes (or overnight).

Filling

  • Combine all of the ingredients in a medium saucepan and stir to combine. Mix and heat on medium-low heat until it comes to a simmer.
    2 cups blueberries, ¼ cup granulated sugar, 1-2 tablespoons lemon juice, 1 tablespoon cornstarch, ½ teaspoon ground cinnamon, 2 tablespoons water
  • Let the filling thicken, stirring frequently to prevent burning. Once thickened, remove from heat and immediately transfer to a non-metal heat safe bowl or container to cool. Let cool to room temperature (or refrigerate).

Assembly

  • Whisk egg and milk until smooth, set the egg wash aside for later.
    1 large egg, 1 tablespoon milk
  • On a lightly floured surface, roll out both pieces of crust to form two squares, ¼ inch thick. Trim the edges even.
  • Use a knife to score one of the rolled out pieces into 6 rectangles (or more if you prefer smaller pop tarts). Fill the middle of each with cooled blueberry filling. Reserve the bowl from the blueberry filling for the glaze. Brush in between the fillings to help the crusts seal.
  • Place the second square on top and use your fingers to press down in between each pop tart to help seal the edges. Use a pizza cutter or sharp knife, cut into individual pop tarts.
  • Use a fork to firmly press down on all the edges to seal. Poke the tops to allow steam to escape. Transfer to a parchment lined baking sheet leaving 1-2 inches between each pop tart.
  • Place pop tarts into the freezer for 10 minutes. While they’re chilling, Preheat the oven to 375°F (190°C).
  • Brush tops of the chilled pop tarts with egg wash and sprinkle liberally with coarse sugar. Bake for 20 minutes, until they are golden brown. Let the pop tarts cool on the baking sheet for 10 minutes.
    2 tablespoons coarse sugar

Glaze

  • Add powdered sugar into the reserved bowl from blueberry filling. Add heavy whipping cream, a tablespoon at a time until it forms a thick glaze. Spread on top of cooled pop tarts and enjoy!
    1 cup powdered sugar, 1-3 tablespoons heavy whipping cream

Notes

The pop tarts are best eaten at room temperature or slightly warmed.
Make ahead:
You can make and chill the pie crust and filling up to two days before making the pop tarts. Store them separately in the fridge.
