What are Homemade Pop-Tarts?

Homemade Pop-Tarts are individual filled pastries inspired by the classic store-bought toaster pastry. They are usually made by placing a sweet filling between two pieces of pastry dough, sealing the edges, and baking until golden.

This version uses prepared pie crust to make the process easier. The filling is a thick homemade blueberry sauce, and the baked pastries are finished with a simple blueberry glaze and sprinkles.

Key Ingredients

NOTE: This section highlights ingredients used in the recipe. Find the full printable recipe in the recipe card below.

Blueberries

Frozen blueberries work well and make this recipe easy to prepare any time of year. Fresh blueberries can also be used.

Granulated sugar

Sweetens the blueberry filling and balances the tartness of the berries and lemon juice.

Cornstarch

Helps thicken the blueberry mixture so it becomes jammy and stays inside the pastries.

Lemon juice

Adds brightness and helps balance the sweetness of the filling.

Salt

Enhances the flavor of the blueberry filling.

Pie crust

Refrigerated pie crust saves time while still giving the Pop-Tarts a flaky pastry exterior.

Egg

Used with milk to make an egg wash for sealing and browning the pastries.

Milk

Added to the egg wash and also used to make the glaze.

Powdered sugar

Creates the base of the sweet glaze.

Reserved blueberry sauce

Adds blueberry flavor and color to the glaze.

Sprinkles

Add a fun finishing touch.

Ingredients & Substitutions

NOTE: This section suggests substitutions. Find the full printable recipe in the recipe card below.

Frozen blueberries – Fresh blueberries can be used in place of frozen. If using fresh blueberries, reduce the cooking time for the filling to about 10-15 minutes.
Granulated sugar – Light brown sugar can be substituted for the granulated sugar, although it will give the filling a slightly deeper flavor and darker color.
Cornstarch – Arrowroot starch is a good alternative to cornstarch. All-purpose flour can work in a pinch, but you will need more of it to achieve the same thickening power, and the finished filling may look less glossy. Whichever thickener you use, cook the blueberry mixture until it is thick and jammy before filling the pastries.
Lemon juice – Lime juice is the closest substitute and will provide similar acidity with a slightly different flavor.
Salt – I don’t recommend omitting the salt entirely since a small amount helps balance the sweetness and enhance the blueberry flavor. Fine sea salt can be used in place of regular table salt.
Refrigerated pie dough crusts – A homemade pie crust can be used instead. If using homemade dough, roll it out and cut it into 3×4-inch rectangles as directed.
Egg – The egg is used for the egg wash, which helps seal the pastries and promotes browning. If you need to omit it, milk or heavy cream can be brushed onto the pastry instead, although the finished pastries may not brown or seal quite the same way.
Milk – Any milk you typically use should work for the egg wash and glaze. Half-and-half can also be used. For a dairy-free alternative, use an unsweetened, unflavored non-dairy milk.
Powdered sugar – I don’t recommend substituting another type of sugar in the glaze.
Reserved blueberry sauce – This gives the glaze its blueberry flavor and color. If you don’t want a blueberry-flavored glaze, you can omit it and make a simple powdered sugar and milk glaze instead. You may need to adjust the amount of milk to reach the desired consistency.
Sprinkles – Use any color or variety of sprinkles you like, or leave them off entirely.

Variations

Use fresh blueberries – Fresh blueberries can be used instead of frozen. Reduce the cooking time for the filling to about 10 to 15 minutes.
Make the glaze darker – Reserve up to 2 tablespoons of blueberry sauce if you want a deeper purple glaze. Keep in mind that the additional liquid may make the glaze thinner.
Change the sprinkles – Use different colors to match holidays, birthdays, baby showers, or other occasions.
Skip the sprinkles – Leave them off for a simpler finish.
Skip the glaze – If you prefer a less sweet pastry, serve the Pop-Tarts without the glaze.

Tips for Best Results

Let the pie crust come to room temperature before trying to roll or cut it.
Cook the blueberry mixture until it is thick and jammy.
Let the blueberry filling cool completely before assembling the pastries.
Warm filling can melt the butter in the pie crust and lead to soggy pastries.
Do not overfill the Pop-Tarts.
Leave enough empty dough around the filling to create a good seal.
Brush the edges with egg wash before adding the top crust.
Press the edges together before crimping them with a fork.
Prick holes in the top of each pastry so steam can escape.
Let the pastries cool completely before adding the glaze.
Allow the glaze to fully set for a firmer finish.

FAQs

Can I use fresh blueberries instead of frozen?

Yes. Fresh blueberries can be used in place of frozen blueberries. Reduce the cooking time for the blueberry filling to about 10 to 15 minutes.

What is the best way to thaw frozen pie crust?

Allow the refrigerated pie crusts to come to room temperature for at least 20 minutes. If frozen, thaw them for about an hour. You can also thaw them in the refrigerator for up to 24 hours if you are preparing ahead.

Do I have to let the blueberry filling cool before assembling the Pop-Tarts?

Yes. The filling should cool completely before assembly. Warm filling can melt the butter in the pie crust and result in soggy pastries instead of a flaky crust.

How do I prevent the filling from leaking out during baking?

Do not overfill the pastries, and leave enough empty dough around the filling to create a complete seal.

Brush the edges with egg wash, press them together with your fingers, and then crimp them with a fork.

Why do I need to prick holes in the top of the dough?

The holes allow steam to escape while the pastries bake. This helps prevent the Pop-Tarts from bursting in the oven.

What should I do if I do not get enough rectangles from the pie crust?

Gather the leftover dough scraps and gently reroll them. Continue cutting rectangles until you have 12 to 16 pieces total.

Can I warm homemade Blueberry Pop-Tarts in a toaster?

No. Do not place glazed homemade Pop-Tarts in a traditional pop-up toaster. The glaze can melt and drip into the toaster, creating a mess and a potential fire hazard.

Can I use homemade pie crust for Blueberry Pop-Tarts?

Yes! Homemade pie crust works well for these Blueberry Pop-Tarts. Roll the dough out, cut it into 3×4-inch rectangles, and assemble the pastries as directed. Keep the dough cold while you work so the butter stays firm and the crust bakes up flaky.

Storage

Store leftover Blueberry Pop-Tarts in an airtight container in the refrigerator for up to 3 days.

Do not reheat glazed Blueberry Pop-Tarts in a traditional pop-up toaster. The glaze can melt, drip into the toaster, and create a mess or potential fire hazard.
