Sourdough pop tarts are a nostalgic treat elevated with the rich, slightly tangy depth that only sourdough can bring. Unlike store-bought versions, these homemade pastries are flaky, buttery, and customizable with your favorite fillings—from classic strawberry jam to indulgent chocolate hazelnut spreads. They’re perfect for breakfast, snacks, or even dessert, and a fantastic way to use up sourdough discard.
Why Use Sourdough in Pop Tarts?
Sourdough isn’t just for bread—it adds complexity and improves texture in pastries too. Using sourdough discard in pop tarts gives:
- Flavor depth: A subtle tang enhances sweet fillings
- Tender texture: The dough becomes softer and more delicate
- Reduced waste: A great way to use leftover starter
- Digestibility: Fermented dough can be easier on the stomach
You don’t need an active starter here—discard works perfectly.
Ingredients
For the Sourdough Pastry Dough:
- 2 cups (250g) all-purpose flour
- 1 tablespoon sugar
- ½ teaspoon salt
- 1 cup (225g) cold unsalted butter, cubed
- ½ cup (120g) sourdough discard (unfed)
- 2–4 tablespoons cold water
For the Filling (Choose One or Mix):
- Fruit jam (strawberry, raspberry, blueberry)
- Chocolate spread or melted chocolate
- Brown sugar + cinnamon mixture
- Sweet cream cheese filling
For the Egg Wash:
- 1 egg
- 1 tablespoon milk
For the Glaze:
- 1 cup powdered sugar
- 1–2 tablespoons milk or lemon juice
- Optional: vanilla extract or food coloring
Step-by-Step Instructions
1. Make the Dough
In a large mixing bowl, whisk together flour, sugar, and salt. Add the cold butter cubes and use your fingers or a pastry cutter to work it into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces.
Stir in the sourdough discard and mix gently. Add cold water one tablespoon at a time until the dough just comes together. Do not overmix.
Shape into a disk, wrap in plastic, and refrigerate for at least 1 hour (or overnight for better flavor).
2. Roll and Cut
Lightly flour your surface and roll out the chilled dough into a large rectangle about ⅛ inch thick. Trim the edges and cut into equal rectangles (about 3 x 4 inches).
You should have an even number of rectangles—half for the bottoms, half for the tops.
3. Fill and Seal
Place half the rectangles on a parchment-lined baking tray. Spoon 1–2 tablespoons of filling into the center, leaving a border around the edges.
Brush the edges with egg wash, then place another rectangle on top. Press gently to seal, then crimp edges with a fork.
Poke a few small holes in the top to allow steam to escape.
4. Chill Again (Optional but Recommended)
Place assembled pop tarts in the fridge for 15–20 minutes. This helps them hold shape and improves flakiness during baking.
5. Bake
Preheat oven to 190°C (375°F). Brush the tops with egg wash.
Bake for 20–25 minutes, or until golden brown and crisp.
Let cool completely before glazing.
6. Glaze and Decorate
Mix powdered sugar with milk or lemon juice until smooth. Spread or drizzle over cooled pop tarts.
Add sprinkles, drizzle chocolate, or leave plain for a more rustic look.
Flavor Variations
One of the best things about sourdough pop tarts is how customizable they are:
- Classic Strawberry: Jam filling with vanilla glaze
- Brown Sugar Cinnamon: Cozy and nostalgic
- Chocolate Hazelnut: Rich and dessert-like
- Apple Pie: Spiced apple filling with cinnamon glaze
- Savory Twist: Try cheese and herbs or spiced potatoes
Tips for Success
- Keep everything cold: Cold butter = flaky layers
- Don’t overfill: Prevents leaking during baking
- Seal well: Use egg wash and fork crimping
- Chill before baking: Helps structure and texture
- Use parchment paper: Avoid sticking and burning
Storage & Reheating
- Store in an airtight container at room temperature for 2 days
- Refrigerate for up to 5 days
- Freeze unbaked or baked pop tarts for up to 2 months
To reheat, bake in the oven at 180°C (350°F) for 5–10 minutes or toast lightly.
