Blueberry Pop Tarts

There’s something intoxicating about warm pastry and berries — the smell of butter and caramelizing sugar, the pop of sweet-tart blueberries, and the tender, flaky layers that yield with a delicate crunch. These homemade Blueberry Pop Tarts capture that comfort: steaming pockets of jammy blueberry filling tucked inside a golden, buttery crust and finished with a glossy glaze that catches the light. One bite delivers a contrast of textures — flaky pastry, jammy fruit, and silky icing — and a bright, lemon-lifted note that keeps you coming back.

This recipe is perfect for cozy weekend mornings, making ahead for a brunch spread, or gifting as a homemade treat during the holidays. They’re handheld and nostalgic, great for kids and grown-ups alike. If you love blueberry-forward breakfasts, you might also enjoy this baked breakfast classic: Blueberry Baked Oatmeal.

Preparation Guide

Ingredients

2 ½ cups all-purpose flour
1 cup unsalted butter (cold, cubed)
½ teaspoon salt
6 tablespoons ice water
1 ½ cups blueberries (fresh or frozen)
¼ cup granulated sugar
1 tablespoon cornstarch
1 tablespoon lemon juice
1 egg (for egg wash)
1 cup powdered sugar
2–3 tablespoons milk
1 tablespoon blueberry puree or jam

Optional ingredients and substitutions:

For a richer crust: substitute 2 tablespoons of butter with cold heavy cream (adds tenderness).
Vegan option: use vegan butter and a flax “egg” for seal (1 tbsp ground flax + 3 tbsp water) and a plant milk for the glaze.
Gluten-free: use a 1:1 gluten-free flour blend and reduce water slightly if the dough feels sticky.
Lower sugar: reduce granulated sugar and powdered sugar by 25% and use a sugar substitute suitable for baking.

Step-by-step Instructions

Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a large bowl, combine the flour and salt. Cut in the cold cubed butter using a pastry cutter, two knives, or food processor until the mixture resembles coarse crumbs (pea-sized bits of butter are ideal).
- Tip: Keep the butter cold to ensure a flaky crust; if butter softens, chill the mixture briefly.
Add the ice water one tablespoon at a time, tossing gently with a fork until the dough just comes together. Do not overwork. You should have a cohesive dough that holds when squeezed.
Divide the dough into two discs, wrap each in plastic wrap, and chill for 30 minutes. Chilling relaxes gluten and firms the butter.
While the dough chills, make the blueberry filling: In a small saucepan over medium heat, combine the blueberries, granulated sugar, lemon juice, and cornstarch. Cook, stirring frequently, until the mixture thickens and becomes glossy (about 5–8 minutes). Remove from heat and let cool completely. If you prefer a very smooth filling, pulse slightly with a hand blender or mash.
- Tip: If using frozen blueberries, cook a bit longer to evaporate excess liquid.
On a lightly floured surface, roll out one chilled dough disc into a rectangle about 1/8" thick. Cut into four equal rectangles (about 3×4" each). Repeat with the second disc to yield eight top pieces and eight bottom pieces total.
Place four bottom rectangles on the prepared baking sheet. Spoon about 1–2 tablespoons of cooled blueberry filling onto each bottom rectangle, keeping a ¼" border around the edges.
Brush the edges lightly with beaten egg (egg wash) and place a top rectangle over each filled bottom. Press edges together gently, then seal by crimping with the tines of a fork. Poke 2–3 small vents in the top to allow steam to escape.
Brush the tops with egg wash for a golden finish and bake for 22–25 minutes, until puffed and deep golden brown. Rotate the pan halfway through baking for even color.
- Practical tip: If the edges brown too quickly, tent loosely with foil for the last 5–8 minutes.
Transfer to a rack to cool completely before glazing. Cooling prevents the glaze from melting off.
Make the glaze: mix the powdered sugar with 2 tablespoons milk and 1 tablespoon blueberry puree or jam. Add a little more milk (up to 1 more tablespoon) to reach a thick but pourable consistency. Drizzle or spread over cooled tarts and allow to set before serving.

Serving Suggestions

Best Pairings

Classic morning: Serve warm or at room temperature with a mug of strong coffee or a bright black tea.
Brunch board: Include sliced cheeses, yogurt, fresh fruit, and a savory option like eggs or smoked salmon to balance sweetness.
Snack idea: Cut into halves for a kid-friendly snack box or pair with a dollop of plain Greek yogurt for protein.
For a savory contrast at a late breakfast spread, pair these with soft, seeded bread like 3-Ingredient Poppy Seed Bagels and cream cheese.

Keeping it Fresh

Room temperature: Store in an airtight container at room temperature for 1–2 days (avoid humid conditions).
Refrigeration: Keep covered in the fridge for up to 4–5 days. Bring to room temperature or warm briefly before serving to revive flakiness.
Freezer: Individually wrap cooled pop tarts in plastic and freeze in a sealed bag or container for up to 2 months. Reheat from frozen at 325°F (160°C) for 10–15 minutes, or thaw overnight and warm briefly.

Pro Tips & Tricks

Keep everything cold: Cold butter and minimal handling are the keys to a flaky crust. If dough warms, chill briefly before rolling.
Don’t overfill: Overfilling leads to burst seams and leaking filling. Use measured portions and leave a clean border to seal.
Crimp well: Use a fork to crimp edges securely; a little egg wash helps glue the edges together.
Prevent sogginess: Thicken the filling well (it should be glossy and hold its shape) and cool it completely before assembling to avoid soggy bottoms.
Glaze control: If you want a thinner glaze (more sheen), add milk 1/4 teaspoon at a time until desired consistency; thicker glaze sets better and reduces stickiness.

Fun Flavor Ideas

Lemon-Blueberry: Add 1 teaspoon lemon zest to the dough and 1 teaspoon to the glaze for extra brightness.
Cream Cheese Swirl: Fold 1/4 cup sweetened cream cheese into the blueberry filling before assembling for a tangy ribbon.
Brown Butter Crust: Brown the butter, chill until solid, and use in place of cold butter for a nutty, caramel note (works best if you chill the brown butter thoroughly first).
Vegan Blueberry: Use vegan butter and a plant-based milk/glaze; replace the egg wash with plant milk for shine.
Spiced Berry: Stir 1/2 teaspoon ground cardamom or cinnamon into the blueberry filling for warmth.

Recipe Q&A

Q: Can I use frozen blueberries?
A: Yes — use them straight from the freezer and cook a bit longer to reduce excess liquid. Strain if needed to concentrate the filling.

Q: My crust was tough — what went wrong?
A: Likely overworking the dough or using warm butter. Chill the dough, handle gently, and roll briefly.

Q: How do I prevent the filling from leaking?
A: Ensure the filling is well-thickened and cooled, leave a clear border when filling, and press/crimp firmly with egg wash for a good seal.

Q: Can I make these ahead and freeze?
A: Yes — freeze fully cooled tarts individually wrapped for up to 2 months and reheat before serving.

Q: Any healthier swaps?
A: Use less sugar in the filling and glaze, swap half the all-purpose flour for whole wheat pastry flour for added fiber (texture will be heartier), or make smaller tarts to reduce portion size.
