Introduction: Evoking Breakfast Nostalgia

As a kid growing up in the 80s, boxed Pop-Tarts were a go-to breakfast. In a world inundated with processed and packaged breakfast treats, there is something undeniably comforting about the nostalgic pop of a toaster paired with the aroma of warm, gooey filling and the too-sweet hard icing. Many of us have similar fond memories of the iconic boxed Pop-Tarts that accompanied our mornings, but what if we told you there’s a way to elevate that nostalgic experience to a whole new level of deliciousness and wholesomeness, without the processed stuff?

After sampling some delicious homemade pop tarts at a local farmer’s market, we made it our mission to create a sourdough version, and I think we nailed it! These sourdough pop tarts bring back the flavours of our childhood but also introduce a preservative-free, healthier twist. And let’s be honest, they are just so much tastier than the boxed variety and contain only a few simple ingredients.

Tips for Making the Dough

The key to making these sourdough pop tarts is a really good pastry dough. To do this, you need to keep all the ingredients COLD. You can place all the dough ingredients in the fridge or freezer before mixing so the dough stays cold.

  1. Combine all the dry ingredients and mix them in a bowl.
  2. Use a box grater instead of your fingertips to grate the butter and keep it cold.
  3. Mix the dough together quickly to prevent your hands or the ambient temperature from warming up the dough.
  4. Once you have brought the dough together chill for at least 1 hour before rolling it out. When the dough is chilled it is much easier to work with and results in a much better pastry after baking.

Assembling the Sourdough Pop Tarts

Assembling the pop tarts can be tricky but gets easier with practice. I like to roll out the dough into sheets and then place it back into the fridge or freezer before cutting. Resting and chilling the sourdough pop tart dough each step of the way will really help make a better final pop tart.

  1. Once you have cut the dough into rectangles, egg wash one side only. If you egg wash both sides the dough will slide together instead of stick together.
  2. Use a spoon to scope a small amount of filling into the middle of the dough rectangle. I used a homemade blackberry jam for this recipe but you can also use your favourite store-bought jam.
  3. Place another piece of dough on top of the filling and the first piece. Use your fingers to press the dough around the edges then use a fork to crimp the sides helping the sourdough pop tart stay together.
  4. I like to chill the dough again briefly (20 minutes) after assembling and before baking.

Tips for Icing the Pop Tarts

While icing the sourdough pop tarts is optional, it is highly recommended especially if you want that classic pop tart look to your pastry. Make sure you have everything ready and your pop tarts have cooled to room temperature after baking before you glaze them. If the pop tarts are warm the glaze will melt a bit.

Use a spoon or offset spatula to apply a nice layer of the glaze on the top of your pop tarts. Before they have cooled sprinkle them with sprinkles if you want to use them.

Storing Your Pop Tarts

While you probably will have no problem eating the whole batch of sourdough pop tarts, they can be stored for the long term. If you do plan on freezing a bunch of them, you can do so without the icing so that you can reheat them in the toaster or oven later.

  • Store your pop tarts in a sealed air-tight container at room temperature for 3-4 days.
  • Pop tarts can also be frozen in a plastic or reusable air-tight bag for up to 3 weeks. For defrosting, it is best to use an oven or toaster oven until warm and crisp. You can also use a microwave to warm them up.
