Why You’ll Love This Recipe

  • A great way to use discard: Have discard on hand? This is a delicious way to use it!
  • Tastes better than the original: with a brown sugar cinnamon filling and a sweet glaze, these buttery pastries are even better than the boxed version.
  • Simple ingredients: Made with pantry staples you probably already have on hand.
  • Clear step-by-step directions: Easy to follow instructions and photos walk you through each step.
  • Flexible for your schedule: Prep the pastry ahead of time or keep a batch in the freezer for fresh Pop-Tarts whenever you’re craving one!

Tools You’ll Need:

  1. Mixing Bowls-to combine pastry crust if mixing dough by hand, the brown sugar filling, and the glaze.
  2. Pastry Blender (optional)- helpful to mix and combine the pastry dough when mixing by hand. I love this pastry blender but this is entirely optional and I’ll show you how to make the dough without it.
  3. Digital kitchen scale (optional)– for accurate measuring especially helpful with sourdough baking.
  4. Cheese Grater (if mixing by hand)- if you’re mixing this pastry dough by hand, I highly recommend using a cheese grater to grate your butter into even pieces. If you don’t have one, you can also cut the butter. This is the cheese grater I use linked here.
  5. Food Processor (if using food processor method)- If you want to make this pastry using a food processor, you’ll need a food processor with the chopping attachment.
  6. Rolling pin- to roll out your pastry dough.
  7. Tape measure or ruler- to measure your pastries if you want them even.
  8. Fork- to crimp the edges of the pop-tarts.
  9. Pastry brush- for the egg wash. You can also use a folded paper towel.
  10. Baking Sheets- to bake the pop-tarts.
  11. Parchment Paper- to line the baking sheet to avoid the pastries sticking to the pan.
  12. Whisk- to combine the cinnamon glaze.
  13. Spoon- for spreading the glaze on the pop-tarts.
  14. Cool rack (optional)- to cool the pop-tarts.

Gather Your Ingredients:

  1. All-purpose Flour- Creates the base of the pastry. You’ll also use flour for the filling.
  2. Sourdough discard– Adds flavor and moisture and is the magic that ferments your pie crust if you choose. You can use starter or discard that is straight from the fridge, just make sure it’s cold so the dough stays cold.
  3. Unsalted Butter- You want to use very cold butter for the pastry, I really love Kerrygold butter for the flavor and texture but any butter will work. You’ll also need butter for the filling.
  4. White Sugar- adds a touch of sweetness to the crust.
  5. Sea Salt- balances the sweetness in the pop-tarts.
  6. Baking Powder- the secret ingredient I add to give a little extra lift to my pastries and a flaky texture.
  7. Lemon Juice- the acid from the lemon juice breaks down the gluten and makes the crust so tender.
  8. Ice Water- binds the crust without activating the gluten too much.
  9. Brown Sugar- creates that rich filling; you can use light or dark.
  10. Cinnamon- this is added to the filling for that classic flavor and warmth. You’ll also use this in the cinnamon glaze.
  11. Vanilla Extract- added for a touch of sweetness to the filling and glaze.
  12. Powdered Sugar- thickens and sweetens the cinnamon glaze. Do not use granulated sugar or the glaze will be gritty.
  13. Light corn syrup (optional)- this gives the glaze a shine and helps it set and harden. You can skip it and use extra milk but the texture of the glaze may not be as close to a pop-tart.
  14. Maple Flavoring (optional)- I recommend adding some maple flavoring to the icing it’s absolutely divine. I love this Maple Flavoring that is Organic and non-GMO from Frontier Co-op.
  15. Whole Milk- thins the glaze for the desired consistency.
  16. Egg- for the egg wash.
Step-by-step Instructions
Step 1: Mix the Pastry Crust

This pastry crust can be made by hand or by using a food processor, I will give you both options, depending on what fits your needs.

Mixing by hand: Combine the flour, white sugar, baking powder, and salt in a mixing bowl. Whisk together.

Using a cheese grater on the largest setting, grate your cold butter and transfer it to the bowl with the dry ingredients.

Mix in the butter until it’s fully coated in the flour mixture, you should see pea-sized chunks of butter in the dough.

Add the cold sourdough discard and lemon juice to the bowl, and start to combine the dough.

Begin to mix with a pastry whisk or your hands to bring the dough together. If you need to, you can turn your dough out on a clean surface to mix it with your hands.

The ball of dough should come together easily, if it’s too dry add a teaspoon of cold ice water at a time until your dough just comes together.

If the dough is too wet or sticky, sprinkle with a little flour and continue to bring the dough together.

I typically don’t even need to use water, but it’s okay and normal if you do!

Because your hands can melt the butter, it’s important to just bring the dough together and then stop mixing. You want chunks of butter and overworking the dough isn’t the goal.

Flatten the dough into a disc, and cut the dough in half (this doesn’t have to be perfect just guess). You want to see the bits of butter throughout your dough, this is what makes those flakey layers!

Flatten each half into a round, then wrap tightly in plastic wrap and refrigerate at least 2 hours but optionally overnight for longer fermentation.

Food Processor Option: Add the flour, white sugar, baking powder, and salt to the bowl of your food processor fitted with the blade attachment. Pulse a few times to combine all of the dry ingredients.

Cut up your butter (make sure it’s very cold), into 1/4 inch cubes. Add the butter to the dry ingredients.

Pulse the butter until you have blueberry sized balls of butter cut up into the flour mixture. Don’t over blend the butter into the flour at this stage! Go slow and stop when you see the butter is chopped up to the desired size.

Add the sourdough discard and the lemon juice to the work bowl.

Pulse together the ingredients slowly until a dough starts to form. If the dough is very dry, you can add 1 teaspoon of ice water at a time until the dough just comes together.

Once a pie dough is forming, dump out the dough onto a clean work surface and use your hands to bring the dough together. You want to see the bits of butter throughout your dough, this is what makes those flakey layers!

Divide the dough, and flatten both sections into discs and wrap tightly in plastic wrap.

Refrigerate the pastry dough at least 2 hours but optionally overnight for the longer fermentation.

Step 2: Make the Brown Sugar Cinnamon Filling

In a small bowl, add the softened butter. Make sure this isn’t MELTED or the filling will be too runny.

Add the brown sugar, cinnamon, flour, salt, and vanilla extract to the softened butter.

Using hand beaters or a spatula, mix the filling really well until it forms a smooth paste like mixture. Set aside for filling the pop-tarts.

Step 3: Shape the Tarts

Line 2 baking sheets with parchment paper, and set aside.

On a well floured surface (this is important to avoid sticking), roll one disc of dough into a 9 × 12-inch rectangle, about ⅛ inch thick. The bottom and top edges should be 9 inches, the sides 11 inches.

Using a pizza cutter or sharp knife, trim the edges until even. Cut the dough in half lengthwise to create two long strips about 4 1/2 inches wide.

Next, cut each strip into four equal pieces horizontally to make eight rectangles measuring approximately 4 1/2 × 3 inches.

Gently lift these sections of dough and place on a parchment lined baking sheet, and transfer to the refrigerator to chill and set up. This dough is very buttery, so frequently chilling these tarts is key to shaping them.

Repeat the same shaping step as listed above with the second disc to create 16 rectangles total. Make sure you chill the shaped sections of dough for about 30 minutes before you proceed with filling the pop-tarts.

Step 4: Fill the Pop-Tarts

Remove on of the sheets of shaped dough from the refrigerator, and gather your brown sugar cinnamon filling.

Spread about 1½ tablespoons of brown sugar cinnamon filling onto each rectangle, leaving a 1/4-inch border around the edges. Don’t overfill these or you will have a lot of leakage.

Top the 8 tarts with filling with the remaining sections of dough in the refrigerator. Gently press out any trapped air with your fingers, and crimp all of the edges of the tarts with a fork to seal them together.

If the dough is cold and wants to crack, allow the tarts to rest a few minutes to allow the dough to soften before proceeding.

Using your fork, poke your tarts 4 or 5 times on the top to create vents for the steam so they don’t split open.

Refrigerate the assembled Pop-Tarts for 20–30 minutes while the oven preheats.

Success Tip: Don’t skip the listed chill times, or the butter will melt and make the dough harder to shape and your tarts will not be as flaky and hold their shape in the oven. If you are noticing the dough is hard to work with, pause and chill and then resume making the tarts.

Step 5: Bake the Pop-Tarts

Preheat the oven to 375°F (190°C) while the tarts are chilling.

Beat the egg and water in a small bowl, until smooth.

Brush the tops of the pop tarts with the egg wash using a pastry brush or folded paper towel, then transfer the tarts to the oven. Make sure the oven is fully preheated before baking!

Bake the Pop-Tarts for 22–26 minutes, or until the pastries are deeply golden brown.

Allow them to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. If there is a little cracking don’t worry, the glaze will cover any imperfections.

Step 6: Glaze the Pop-Tarts

The last step to the perfect pop-tart, is to glaze them!

Whisk together the powdered sugar, milk, vanilla, maple extract (if using), cinnamon, and salt until smooth in a small mixing bowl.

Stir in the corn syrup, if you’re using it. This is optional, but helps give the glaze that classic shine and set.

If needed, add additional milk, 1 teaspoon at a time, until the glaze is thick but spreadable. It should slowly run off your spoon!

Spread 1-2 Tablespoons of the cinnamon glaze over the cooled Pop-Tarts and let the glaze set for 30–60 minutes before serving. I like to sprinkle the tops with an extra pinch of cinnamon for a pretty garnish. Enjoy!

FAQ’S
Can I use active sourdough starter instead of discard?

You can use any starter or discard as long as it’s COLD. This is key to keeping the butter from melting in the pastry crust.

Can I skip the corn syrup?

Yes. It simply gives the glaze a shinier finish and helps it set The glaze is still delicious without it.

Why did my filling leak?

Most likely the pop-tarts were too warm and not cold enough before baking or you overfilled the tart.

Do I have to add maple to the glaze?

No! You can skip it I just love the added flavor.
