Ingredients Needed

* 1 cup + 1 teaspoon all-purpose flour
* 8 tablespoons unsalted butter (cold)
* ½ teaspoon fine sea salt
* 2 tablespoons granulated sugar
* ½ cup sourdough discard
* 1 teaspoon white vinegar
* ½ cup strawberry jam (see notes)
* egg wash (1 egg lightly beaten)
* ½ cup powdered sugar
* 1 teaspoon water

Ingredient Notes & Substitutions

When it comes to sourdough discard, unfed, inactive discard is ideal for this recipe. This ensures you get its unique flavor and tenderizing qualities without excessive leavening, which can make pastries puff up too much. Sourdough discard is simply the portion of your sourdough starter that you remove before feeding it, and it is a fantastic ingredient for adding depth to baked goods.

Using very cold unsalted butter is absolutely crucial for the flakiest crust. Grating the cold butter directly into your flour mixture helps create those desirable flaky layers. Unsalted butter is preferred as it gives you control over the salt content; if you use salted butter, simply reduce the fine sea salt by about ¼ teaspoon.

All-purpose flour is the standard choice for pastry dough. It provides the right structure. Be mindful not to overwork the dough to avoid excessive gluten development, which can lead to a tough crust.

White vinegar plays a very specific role in this pastry dough. It helps tenderize the gluten development in the flour, which in turn makes the crust more tender and flaky. Don’t worry, you will not taste it in the final product.

Strawberry jam is the delightful base for our filling. However, other common fruit fillings like blueberry jam or raspberry jam are also excellent choices.

The freeze-dried strawberry powder is part of our unique twist. It should be finely ground, perhaps in a spice grinder, and is added to the dry crust ingredients. This provides an intense strawberry flavor and a beautiful pink hue. You can typically find freeze-dried strawberries in the snack or dried fruit aisle of most grocery stores.

Almond extract is the other part of our unique twist. This is added to the glaze and truly enhances the berry flavors, giving the pop tarts a more sophisticated and artisanal taste.

Egg wash is a simple mix of one egg lightly beaten with a touch of water. It is brushed over the pop tarts before baking to give them a beautiful golden brown and shiny finish.

How to Make Sourdough Discard Pop Tarts

Prepare the Dough Base

In a medium mixing bowl, I whisk together the all-purpose flour, granulated sugar, and fine sea salt. This ensures all the dry ingredients are evenly distributed. Then, using a cheese grater, I carefully grate the very cold unsalted butter directly into the flour mixture. It is essential for a flaky crust to keep that butter as cold as possible. Next, I use a bench scraper or a pastry cutter to cut the butter into the flour until the mixture resembles large crumbles, with some pea-sized pieces of butter still visible. This specific technique is what ensures you get a truly flaky crust. At this point, I would incorporate my unique twist: add 1 tablespoon of finely ground freeze-dried strawberry powder to these dry ingredients, mixing it in thoroughly.

Form the Dough

Now I add the sourdough discard and white vinegar to the butter-flour mixture. Using a fork, I gently mix the dough until it just starts to come together. Then, I quickly use my hands to gather the mixture into a cohesive ball. I press it into a rough rectangular shape. If the dough feels too dry and crumbly to come together, I might add exactly one teaspoon of cold water, but be careful not to add too much. The key is to mix dough as little as possible to prevent excessive gluten development and a tough crust.

Chill the Dough

I wrap the dough tightly in plastic wrap. Using a rolling pin, I gently flatten and smooth the edges of the wrapped dough into a rectangle, aiming for about 1-inch thick. This initial shaping helps later. I then chill dough in the fridge for at least one hour. Ideally, I recommend chilling it for up to 24 hours. Chilling is crucial because it firms up the butter, which creates those amazing flaky layers, and also relaxes the gluten, making the dough much easier to roll out smoothly.

Preheat & Prep

When I am ready to bake, I preheat my oven to 350°F (177°C). I then line a baking sheet with parchment paper, which prevents sticking and makes cleanup a breeze.

Roll and Cut

On a lightly floured surface, I roll dough into a uniform rectangle, aiming for approximately ⅛” thickness. Consistency here helps with even baking. I then use a sharp knife or my bench scraper to cut strips of dough, usually aiming for four equal rectangles. Finally, I brush the edges of each rectangle with egg wash.

Fill and Seal

I carefully place about 2 tablespoons of my chosen fruit filling, like strawberry jam, onto one half of each dough rectangle. It is important not to overfill to prevent leakage. Then, I fold dough over the filling to create the pop tart shape. Using a fork, I firmly press and seal edges all around, ensuring no filling can leak out during baking. A proper seal is critical to avoid messy leaks. For a beautiful golden brown finish, I brush the tops of the assembled pop tarts with egg wash.

Bake

I carefully transfer the prepared pop tarts onto the lined baking sheet. I bake them for 25-30 minutes, or until the crust is golden brown and appears wonderfully flaky. Once baked, I remove them from the oven and transfer them immediately to a cooling rack.

Glaze

In a small bowl, I whisk the powdered sugar and water together until I achieve a thick, smooth consistency for the glaze. This is the moment to incorporate the other part of our unique twist: add ¼ teaspoon of almond extract to the glaze here, whisking it in until smooth. It is crucial to ensure the pop tarts are NOT hot when glazing, as the glaze will melt and become thin. Allow them to cool slightly, but they can still be warm.

Finish

While the glaze is still wet, I like to sprinkle with coarse sugar or sprinkles for extra appeal and a beautiful presentation. Then, I allow the glaze to set completely before serving.

Essential Tools & Flavorful Fillings

Essential Tools for Homemade Pop Tarts

Having the right kitchen equipment can make all the difference in achieving perfect results with ease.

A cheese grater is essential for grating cold butter quickly into the flour. This technique is key for creating those distinct flaky layers in your crust.

A bench scraper or a pastry cutter is ideal for cutting butter into the flour and handling the dough without overworking it or warming it too much. While a fork can work, these tools are far more efficient.

A rolling pin is a must-have for evenly rolling dough to the specified thickness, ensuring consistent baking.

Parchment paper prevents your pop tarts from sticking to the baking sheet and makes cleanup incredibly easy.

A cooling rack allows air circulation for your pop tarts to cool evenly and prevents any soggy bottoms.

A whisk is perfect for combining dry ingredients thoroughly and for creating a smooth, lump-free glaze.

A pastry brush is excellent for applying egg wash evenly over your pop tarts, giving them a beautiful golden brown sheen.

Flavor Variations & Custom Fillings

While our unique strawberry twist is a showstopper, the beauty of homemade pop tarts is the endless possibility for flavor variations. Remember to always ensure any fruit filling isn’t too runny to prevent leakage.

For the strawberry (our unique twist), I highly recommend using strawberry jam along with the freeze-dried fruit powder in the crust and the almond extract in the glaze for that truly intense and sophisticated flavor.

For frosted blueberry, use blueberry jam for a classic alternative. A hint of lemon zest in the glaze can add a lovely brightness.

If you love brown sugar cinnamon, combine ¼ cup brown sugar, 1 teaspoon ground cinnamon, and ½ tablespoon all-purpose flour. The flour helps to absorb moisture and thicken the filling, preventing leaks.

For Nutella pop tarts, simply use Nutella for a rich, chocolate-hazelnut filling that is always a hit.

A delicious, spiced apple butter can make a comforting, autumnal breakfast pastry, perfect for cooler mornings.

Other fruit fillings such as raspberry, apricot, or cherry jams work beautifully. Just be sure to check their consistency.

To prevent filling leakage, always reinforce the importance of not overfilling your pop tarts. Stick to about 2 tablespoons per pop tart. Also, use a fork to firmly seal edges all around the pastry.

Pro Tips & Troubleshooting

Baking homemade sourdough discard pop tarts is a rewarding experience. Here are my top tips and common mistakes to avoid for perfect results every time.

Pro Tips for Perfect Sourdough Pop Tarts

Keep everything cold. Ensure your unsalted butter, sourdough discard, and even your mixing bowl are cold. This is paramount for preventing gluten development and achieving a truly flaky crust.

Do not overwork the dough. Mix just until it comes together. Overworking develops gluten, leading to a tough, less flaky crust. Handle the dough minimally.

Chill time is crucial. Chill dough for at least 1 hour, or up to 24 hours, as recommended. This firms the butter and relaxes the gluten, making the dough easier to roll and ensuring maximum flakiness.

Ensure even rolling. Roll the dough to a consistent ⅛” thickness for even baking and beautiful golden brown results. A rolling pin with thickness guides can be incredibly helpful here.

Seal edges thoroughly. Use a fork to press down firmly and seal edges around the entire pop tart to prevent any fruit filling from leaking out during baking. This is a critical step.

Embrace the unique twist. Do not skip the freeze-dried fruit powder in the crust for an intense berry flavor or the almond extract in the glaze for that gourmet touch. Remember to grind the freeze-dried strawberries finely for best incorporation.

Common Mistakes to Avoid

Adding too much water to the dough is a common pitfall. Only add a teaspoon of cold water if the dough is excessively dry and will not come together. Too much water will make the crust tough and significantly less flaky.

Glazing hot pop tarts will cause your glaze to melt into a thin, transparent layer instead of a thick, creamy frosting. Always allow them to cool on a cooling rack first before applying the glaze.

Not chilling dough enough will make the dough sticky and difficult to handle. It can also result in a less flaky crust because the butter will be too warm.

Overfilling pop tarts with too much fruit filling can lead to leakage during baking, creating a sticky mess and potentially a soggy bottom. Stick to about 2 tablespoons per pop tart.

Uneven baking or a soggy bottom is often caused by inconsistent dough thickness or insufficient baking time. Ensure even rolling and bake until the bottom is also golden brown. If your oven has hot spots, consider rotating your baking sheet halfway through baking.

A tough crust is typically a result of overworking the dough, which develops too much gluten. To avoid this, handle the dough minimally and keep it cold throughout the process.

Serving & Storage

Once you have crafted these homemade sourdough discard pop tarts, you will want to enjoy them at their best and know how to store them for future treats.

Serving Ideas

The absolute best way to enjoy these homemade pop tarts is slightly warm from the oven. This allows the buttery crust and sweet filling to truly shine.

For an extra special touch, garnish generously with coarse sugar or sprinkles while the glaze is still wet. This adds both appeal and a festive look. A little fresh berry garnish or a dusting of freeze-dried fruit powder can also elevate their appearance.

These are perfect as a quick breakfast pastry with your morning coffee or tea. They also make a delightful sweet snack anytime the craving strikes.

For a complete treat, serve your pop tarts alongside a refreshing glass of cold milk or a hot cup of coffee.

Storage and Make-Ahead

Baked sourdough discard pop tarts can be stored in an airtight container at room temperature for up to 2-3 days. The glaze will set, but the crust will remain wonderfully flaky.

For longer storage, keep them in an airtight container in the fridge for up to 5-7 days. Reheating instructions below are recommended for the best texture after refrigeration.

To freeze baked pop tarts, allow them to cool completely. Then, place them in a single layer on a baking sheet and freeze until solid. Once solid, transfer them to a freezer-safe bag or container, where they can be stored for up to 3 months.

You can also freeze unbaked pop tarts, which is a fantastic make-ahead option. Assemble your pop tarts up to the point of baking, but do not brush them with egg wash. Freeze them flat on a parchment paper-lined baking sheet until solid. Then, transfer them to a freezer-safe bag, separating layers with parchment paper. Store for up to 1 month. When you are ready to bake, brush them with egg wash and bake directly from frozen at 350°F (177°C) for 30-40 minutes, or until golden brown and heated through.

For best results when reheating baked pop tarts, place them in a 350°F (177°C) oven or toaster oven for 10-15 minutes, or until warmed through and the crust crisps up again. This method prevents a soggy bottom and revives the pastry perfectly.

While convenient, reheating these homemade pop tarts in a standard toaster is not recommended due to the potential for filling leakage or scorching. An oven or toaster oven provides more even heating and preserves the pastry’s integrity.

Conclusion

Creating your own sourdough discard pop tarts is a truly rewarding experience, transforming a simple childhood treat into an artisanal delight. The unique twist of freeze-dried strawberry powder in the crust and almond extract in the glaze elevates these homemade pop tarts with an intense flavor and sophisticated touch that you will simply adore.

With these detailed instructions and my expert tips, you can achieve incredible success, even if you are new to sourdough baking.
