Introduction
Pop-tarts bring back memories for so many of us—quick weekday breakfasts, after-school treats, or even those late-night cravings. But have you ever thought about making them from scratch using sourdough discard? I did just that recently, and I was amazed at how perfectly they turned out. The crust had that signature golden flake, and the filling options were endless. What made it even better was knowing exactly what went into each bite—no preservatives or artificial flavors, just good, simple ingredients. This recipe is a perfect weekend baking project that feels nostalgic, creative, and rewarding. And once you try it, you’ll wonder why you didn’t start making homemade pop-tarts sooner.
Ingredients
For the Crust
The crust is the foundation of any great pop-tart. This one is tender, slightly tangy from the sourdough discard, and crisp around the edges.
-
1 cup + 1 teaspoon (125 g) all-purpose flour
-
8 tablespoons (113 g) unsalted butter, cold and cut into cubes
-
½ teaspoon fine sea salt
-
2 tablespoons (30 g) granulated sugar
-
½ cup (125 g) sourdough discard (not fed, just room temp)
-
1 teaspoon (5 g) white vinegar
For the Filling
Choose any jam or filling you love—this is where you can get creative.
-
½ cup strawberry jam (or try one of the ideas below)
-
1 egg, lightly beaten (used for brushing edges and tops)
For the Glaze
A simple glaze adds a touch of sweetness and that signature finish.
-
½ cup powdered sugar
-
1 teaspoon water (adjust more or less for desired thickness)
Instructions
1. Prepare the Dough
Begin by combining the flour, sugar, and salt in a large mixing bowl. Add in the cold butter, either grated or cubed, and work it into the flour with your hands or a pastry blender until the mixture resembles coarse sand. This step is key to a flaky crust. Add the sourdough discard and vinegar and mix until a dough forms. If it’s too dry, add a teaspoon of cold water. Don’t overwork the dough—just enough to bring it together. Shape it into a flat rectangle, wrap it in plastic wrap or parchment, and chill it in the refrigerator for at least one hour. This resting time helps the dough relax, making it easier to roll out and enhancing the flavor.
2. Time to Assemble
Preheat your oven to 350°F (177°C) and line a large baking sheet with parchment paper or a silicone mat. On a floured surface, roll the chilled dough out evenly to about ⅛-inch thickness.
Trim the edges for a clean rectangle and then cut it into 8 equal pieces (or more if you prefer smaller tarts). Lightly brush the edges of half the rectangles with beaten egg. Spoon about a tablespoon of jam into the center, keeping it away from the edges. Top with another piece of dough and press gently to seal. Use a fork to crimp the edges for that classic look and to ensure no filling leaks out. Transfer to your baking sheet, brush the tops with egg wash for a golden finish, and poke a few small holes on top with a toothpick to allow steam to escape.
3. Bake and Glaze
Bake your pop-tarts for 25–30 minutes, or until the tops are golden brown and crisp to the touch. Once they’re done, remove from the oven and let them cool completely on the tray.
This is important—glazing them while hot will cause the glaze to melt off. For the glaze, mix the powdered sugar and water until smooth. You can make it thicker for a more opaque finish or thinner for a light drizzle. Spoon the glaze over the cooled pop-tarts and let it set for about 15 minutes before serving.
Fun Filling Ideas
One of the best parts of making homemade pop-tarts is how customizable they are. Here are a few ideas to inspire your next batch:
-
Strawberry Jam – A classic that everyone recognizes and loves
-
Blueberry or Raspberry Preserves – Add a touch of lemon zest for brightness
-
Brown Sugar & Cinnamon – Mix brown sugar, a pinch of cinnamon, and a little flour for a cozy flavor
-
Nutella or Chocolate Spread – Perfect for dessert lovers or kids
-
Apple Butter or Pumpkin Butter – Great for fall baking and seasonal flavors
-
Peanut Butter & Jelly – For a nostalgic twist on two favorites
Experiment with your favorites or whatever you have in the fridge!
Storage Tips
These pop-tarts are just as convenient as store-bought ones but without the additives. Here’s how to store them properly:
-
Room Temperature: Store cooled pop-tarts in an airtight container on the counter for up to 3 days.
-
Refrigerator: Keep them chilled for longer freshness—up to 6 days in the fridge.
-
Freezer: After baking and cooling, wrap each pop-tart tightly in plastic wrap and place in a zip-top freezer bag. They’ll stay fresh for up to 3 months.
To reheat, bake in the oven at 350°F for about 10 minutes. Avoid the toaster if they’re glazed, as the icing can melt and make a mess.
Notes & Tips
-
Cold Ingredients: Always keep your butter and sourdough discard cold for best results. It makes the dough easier to work with and creates a flakier crust.
-
Don’t Overfill: It’s tempting to load up the filling, but too much jam can cause leaking and prevent proper sealing.
-
Glaze Variations: Add vanilla extract, lemon juice, or a pinch of cinnamon to the glaze for a flavor boost.
-
Make a Double Batch: These freeze well, so make extras and enjoy them later.
-
Egg Wash Alternatives: If you’re avoiding eggs, use a brush of milk or cream for a similar golden effect.
Equipment You’ll Need
To keep things simple, here’s what you’ll want ready before baking:
-
Mixing bowls
-
Box grater or pastry blender
-
Measuring cups and spoons
-
Rolling pin
-
Baking sheet
-
Parchment paper
-
Fork for crimping
-
Pastry brush
-
Cooling rack (optional but helpful)
Make It Ahead
Busy week coming up? This recipe works wonderfully with a little prep ahead:
-
Dough: Make the dough a day or two in advance and store it tightly wrapped in the fridge.
-
Assembled Pop-Tarts: You can fully assemble the unbaked pop-tarts and freeze them raw. When ready to bake, pop them straight into the oven and bake a few minutes longer.
-
Glaze: Whip up the glaze ahead of time and store it in the fridge in an airtight container. Let it sit at room temp and stir before using.
Kid-Friendly Activity
If you’re baking with little ones or grandkids, this is a great recipe to involve them in. Let them:
-
Roll the dough
-
Pick their favorite filling
-
Crimp the edges with a fork
-
Add sprinkles to the glaze
It’s a fun, hands-on experience that turns baking into quality family time. Plus, they’ll love eating the result even more when they’ve helped make it.
Variations for Special Diets
Everyone deserves a sweet treat. Here are easy ways to adapt the recipe for different needs:
-
Gluten-Free: Substitute a 1:1 gluten-free flour blend. Be sure to chill the dough well to make rolling easier.
-
Dairy-Free: Use plant-based butter and skip the egg wash or replace it with a non-dairy milk.
-
Low Sugar: Use a low-sugar or no-sugar jam and reduce the glaze or skip it altogether.
These swaps make the recipe more accessible while still keeping the homemade comfort and flavor.
FAQ
Can I use active starter instead of discard?
Yes, active starter will work, though it will give the dough a slightly stronger tang. It’s best to use discard for a milder, buttery crust.
What can I use instead of vinegar?
Lemon juice or apple cider vinegar are both great alternatives. The acidity helps tenderize the dough.
Can I freeze them before baking?
Yes. Assemble them fully, freeze on a tray until solid, then store in a freezer bag. Bake straight from frozen and add a few extra minutes to the baking time.
Do I need to refrigerate them after baking?
Not right away. If you plan to eat them within 2–3 days, room temperature is fine. For longer storage, use the fridge.
Can I reheat them in a toaster?
It’s not recommended if they’re glazed, but if unglazed, yes—just use a low setting and keep an eye on them.
Conclusion
There’s nothing quite like a homemade pop-tart made with love—and sourdough discard. They’re flaky, flavorful, and easy to customize, making them a family favorite and a fantastic way to reduce waste. Whether you fill them with strawberry jam, cinnamon sugar, or chocolate spread, the result is always a little nostalgic and a lot delicious. Try a batch this weekend—you might just start a new tradition in your kitchen.
