Ingredients You’ll Need
The ingredient list is surprisingly simple, but each ingredient plays an important role in creating that perfect flaky texture.
For the Crust
1 cup + 1 tsp flour
Flour forms the base of the pastry dough and gives structure to the pop tarts.
8 tbsp cold butter
Cold butter is the secret to flaky layers. As the butter melts during baking, it creates steam pockets that make the pastry crisp and layered.
½ tsp salt
Salt balances the sweetness and enhances flavor.
2 tbsp sugar
A little sugar sweetens the dough without overpowering it.
½ cup sourdough discard
Sourdough discard adds subtle tanginess and incredible texture.
1 tsp vinegar
Vinegar helps tenderize the dough and keeps it flaky.
Filling Ideas
This is where you can completely customize the recipe based on your cravings.
Some favorite options include:
- Strawberry jam
- Blueberry jam
- Raspberry preserves
- Chocolate spread
- Brown sugar cinnamon filling
- Apple butter
- Nutella
- Cherry preserves
You can even mix flavors together for fun combinations.
Egg Wash
1 beaten egg
The egg wash gives the tops that beautiful golden bakery-style finish.
Glaze
½ cup powdered sugar
1 tsp water
This simple glaze creates the classic glossy pop tart topping. You can also add vanilla extract or lemon juice for extra flavor.
Step-by-Step Instructions
Step 1: Prepare the Dough
Start by making the flaky sourdough crust.
In a large bowl, combine the flour, sugar, and salt. Grate the cold butter directly into the flour mixture using a box grater. This trick helps distribute the butter evenly while keeping it cold.
Use your hands or a pastry cutter to gently work the butter into the flour until the mixture looks like chunky crumbs. Don’t overmix — visible butter pieces are what create flaky layers later.
Next, add the sourdough discard and vinegar. Stir with a fork until the dough starts coming together.
If the dough feels too dry, add tiny amounts of ice water one teaspoon at a time. Be careful not to add too much. The dough should hold together without becoming sticky.
Press the dough into a rectangle shape, wrap it tightly, and flatten slightly.
Place it in the refrigerator and chill for at least 1 hour. You can also chill it overnight for even better flavor and texture.
Why Chilling Matters
Cold dough equals flaky pastry.
Chilling allows the butter to firm back up, which helps create distinct layers while baking. It also makes the dough much easier to roll out cleanly.
Skipping this step can lead to sticky dough and less flaky results.
Step 2: Roll and Cut the Dough
Once chilled, lightly flour your work surface and roll the dough out to about ⅛-inch thickness.
Try to keep the shape rectangular so you can cut even pieces.
Trim the edges for cleaner pop tart shapes, then cut the dough into equal-sized rectangles.
You’ll need matching pairs since one piece becomes the top and the other becomes the bottom.
The thinner the dough, the crispier the final texture will be.
Step 3: Add the Filling
Place half the rectangles onto a parchment-lined baking tray.
Brush the edges lightly with egg wash. This helps seal the pastry together.
Add about 2 tablespoons of filling to the center of each rectangle, leaving space around the edges.
Be careful not to overfill. Too much filling can leak during baking and make the pastry soggy.
Place another rectangle on top and gently press the edges together.
Use a fork to crimp the edges tightly. This not only seals the filling inside but also gives the pop tarts that classic homemade look.
Brush the tops with more egg wash for a beautiful golden finish.
You can also poke tiny holes in the top to allow steam to escape while baking.
Step 4: Bake Until Golden
Preheat your oven to 350°F (177°C).
Bake the pop tarts for about 25–30 minutes or until the edges turn deep golden brown and crisp.
The buttery aroma while these bake is honestly unreal.
The crust should look flaky and lightly puffed with crisp layers around the edges.
Once baked, transfer the pop tarts to a cooling rack and let them cool completely before glazing.
Step 5: Add the Glaze
In a small bowl, mix the powdered sugar and water until smooth.
The glaze should be thick enough to spread but still pourable.
Once the pop tarts have cooled, drizzle or spread the glaze over the tops.
If you glaze them while still hot, the icing will melt into the pastry for a thinner finish. If fully cooled, the glaze stays thick and glossy like classic bakery pop tarts.
For extra fun, top with sprinkles, sugar crystals, or crushed freeze-dried fruit.

Tips for Perfect Sourdough Pop Tarts
Keep Everything Cold
Cold butter is the secret to flaky pastry layers.
Don’t Overwork the Dough
Mix just until combined. Overmixing develops too much gluten and makes the crust tough.
Seal the Edges Well

Chill Before Baking
If your dough gets soft while assembling, chill the trays for 10–15 minutes before baking.
Don’t Overfill
Too much filling can burst out and burn on the tray.
