Homemade pop tarts taste infinitely better than the store-bought version, especially when you build them on a sourdough base. The tartness of the sourdough dough cuts beautifully against sweet jam filling, and you get that satisfying crunch when you bite into the pastry shell. If you have active sourdough starter in your kitchen, you already have the most important ingredient on hand.
How to Make Sourdough Pop Tarts
This recipe yields about 12 pop tarts and takes roughly 3 hours from mixing to cooling. The dough is forgiving and actually benefits from the tang that sourdough develops.
Ingredients
- 1 cup active sourdough starter (fed 4-8 hours prior)
- 2 cups all-purpose flour, plus extra for dusting
- 6 tablespoons cold butter, cubed
- 1/4 cup granulated sugar
- 1/2 teaspoon salt
- 3/4 cup jam or fruit filling of your choice
Method
Mix the dough base
Combine your active sourdough starter with flour, cold butter cubes, sugar, and salt in a large mixing bowl. Use a fork or your fingertips to work the butter into the flour until the mixture resembles coarse breadcrumbs. This creates the flaky texture you want in the pastry shell.
Form the dough
Add just enough water (1-2 tablespoons) to bring the mixture together into a cohesive dough. Don’t overwork it. Flatten into a disk, wrap in plastic, and refrigerate for at least 30 minutes. This resting period relaxes the gluten and makes rolling easier.
Roll out the pastry
On a floured surface, roll the chilled dough to about 1/8-inch thickness. Using a knife or pastry cutter, cut into rectangles roughly 3 inches by 4 inches. You should get 24 rectangles total (12 pairs).
Fill and seal
Place about 1 tablespoon of jam in the center of one rectangle. Top with a matching rectangle and press the edges firmly with a fork to seal. This fork pattern also gives them that authentic pop tart look. Arrange filled tarts on a parchment-lined baking sheet.
Optional egg wash and toppings
Brush the top of each pop tart with a mixture of beaten egg and 1 tablespoon water. Sprinkle with coarse sugar, cinnamon sugar, or colorful sprinkles if desired. This step isn’t required but creates a beautiful, bakery-quality finish.
Bake until golden
Bake at 375 degrees Fahrenheit for 15-18 minutes, until the edges are golden brown and the filling just barely shows at the seams. Don’t overbake or the pastry will become too crisp and dry.
Cool completely
Transfer pop tarts to a wire rack and let them cool for at least 15-20 minutes. They will continue to set as they cool and the filling will firm up. Serve warm or at room temperature.
- Keep all ingredients cold, especially the butter and starter, for the flakiest pastry possible
- If your jam is very loose, cook it down in a saucepan for 5 minutes before filling to prevent leaking during baking
- Make a double batch and freeze unbaked pop tarts on a sheet tray, then bake directly from frozen (add 2-3 extra minutes to baking time)
What to Look For in Sourdough Pop Tart Equipment
- Rolling Surface and Tools: A silicone baking mat or wooden pastry board prevents sticking without adding excess flour. A pastry roller with guides helps you achieve consistent 1/8-inch thickness for even baking.
- Baking Sheets and Liners: Heavy-gauge baking sheets distribute heat evenly and prevent burning on the bottoms. Parchment paper keeps pop tarts from sticking and makes cleanup instant.
- Cooling Racks: A sturdy cooling rack with good airflow underneath is essential to prevent the bottoms from becoming soggy. Look for one large enough to hold at least 8-10 pop tarts at once.
- Pastry Cutters and Sealing Tools: A fluted pastry wheel or sharp knife cuts clean edges. A fork or specialized pastry sealer creates both the seal and the classic decorative pattern.

Frequently Asked Questions
Can I use unfed or inactive sourdough starter?
No, your starter needs to be actively bubbly and at peak rise (usually 4-8 hours after feeding). Active starter provides the leavening and tang that makes these pop tarts special. Inactive starter will result in dense, flat pastries.
What jam flavors work best?
Any jam works, but thicker, less runny varieties like strawberry, raspberry, or cherry are ideal. Thinner jams like marmalade may leak out during baking. If your jam is runny, simmer it for 5 minutes to reduce the liquid content before filling.
Can I freeze these pop tarts?
Yes, freeze them at two stages: unbaked (freeze on a sheet tray, then transfer to a freezer bag) or baked (cool completely, then freeze in an airtight container). Unbaked pop tarts bake beautifully from frozen with just 2-3 extra minutes. Baked ones reheat perfectly in a 300 degree oven for 5 minutes.
Why is my filling leaking out during baking?
You’re either using too much jam (stick to 1 tablespoon per pop tart) or your jam is too thin. The seal around the edges must be tight, so press firmly with a fork. If jam is escaping at the seams, your seal wasn’t complete.
How long do these stay fresh?
Baked pop tarts stay fresh and crispy in an airtight container for 3-4 days at room temperature. After that, they soften slightly but are still delicious. Refrigerating makes them firm up again, though they won’t be quite as crispy as when freshly baked.
