Overview of Ingredients

Freshly Milled Flour
Fresh milling flour right before using ensures it retains its natural oils and nutrients, resulting in a rich, wholesome dough. If you don’t have a mill at home, all-purpose flour can also work, though the flavor will be less robust.

Wild Berries
A mix of wild berries like blueberries, raspberries, blackberries, and strawberries makes the filling lively and fresh. You can substitute with any berries you have on hand.

Butter
Butter adds the necessary richness and flakiness to the crust. 

Sugar
A little sugar sweetens both the dough and filling just right without overwhelming the natural tart berry flavors. If you want to go a bit healthier, try coconut sugar or honey but keep in mind this might slightly change the texture and taste.

Egg Wash
An egg wash gives the pop-tarts a beautiful golden shine. 

Tips for Success

#1 Chill the Dough Thoroughly
After mixing your dough, let it chill in the fridge for at least an hour. This rest period relaxes the gluten and firms the butter, making rolling out the dough easier and preventing it from shrinking as it bakes.

#2 Use a Light Hand When Rolling
Don’t press too hard while rolling out your dough; a gentle touch keeps it flaky and tender. If it starts sticking, lightly dust your surface with more freshly milled flour, but try not to add too much.

#3 Crimp the Edges for a Secure Seal
Use a fork or your fingers to gently press and crimp the edges of your pop-tarts to seal in the filling. This step keeps the filling from bubbling out during baking and gives your pop-tarts a classic look.

#4 Brush with Egg Wash for Perfect Color
Applying the egg wash just before baking helps achieve a golden, buttery crust. It also helps those cute little vent holes steam properly, so don’t skip this step.

​How to Make Homemade Wild Berry Pop-Tarts with Fresh Milled Flour

Ingredients

Berry Filling:

• 16 ounces frozen mixed berries (strawberries, blueberries, raspberries, & blackberries (455 grams)
• ⅓ cup honey (113 grams)
• 1 teaspoon lemon juice
• 2 tablespoons cornstarch, plus 2 tablespoons water

Pop-Tart Dough:

• 3 cups freshly milled soft white wheat flour, finely milled (345 grams)
• 2 tablespoons sugar
• ½ teaspoon salt
• 1 cup cold butter, cubed (230 grams)
• ⅓ cup cold water (73 grams)
• egg for egg wash

Icing:

• 1 ½ cups powdered sugar (150 grams)
• 2-3 teaspoons water
• Natural blue and purple food coloring

Directions:

• In a medium pot, add the berries and cook until softened about 15-20 minutes.
• Use a blender or immersion blender and blend the berries until smooth. Strain through a sieve to get all of the seeds out.
• Put the mixture back in the pot and heat over low-medium heat. Add the honey and lemon juice and stir. 
• Stir together the cornstarch and water and add it to the berries. Allow the mixture to simmer until thickened.
• Allow the mixture to cool. It is best to place this in the fridge to cool and thicken.

• For the dough, place the flour, sugar, salt, and butter in a blender or food processor and pulse until the butter resembles small crumbs. 

• Slowly pour the water in just until the mixture comes together in a ball. 

• Divide the dough in half. Shape into discs, wrap in plastic wrap, and place in the fridge to chill until hardened, about an hour. 

• On a lightly floured surface, roll one of the discs out into about an 8 x 14 inch rectangle. Trim off any uneven edges. Cut the dough in half lengthwise, then cut 3-4 squares that are about 3-4 inches wide.

• Place 1-2 tablespoons of the berry filling on half of them. Get a small bowl of water and dip your finger in it and rub it along the edges of the dough with the filling, then place the other piece of dough on top. You should have 3-4 pop-tarts. 

• Repeat with the remaining dough until you have 10-11 pop-tarts. 

• Use a fork to crimp the edges, then use a knife to cut a small slit in the tops of the pop-tarts.
• Place them on a baking sheet lined with parchment paper and place in the fridge to chill for 20 minutes. 
• Preheat the oven to 375 degrees F.

• Brush the pop-tarts with the egg wash and bake for 20-25 minutes, until golden brown. 
• Allow to cool.

• While cooling, place 1 cup of powdered sugar in a bowl and add 1 teaspoon of water at a time until you get a thick enough consistency to spread, but not too runny. Add desired amount of purple food coloring to this bowl.
• In a small bowl, add ½ cup powdered sugar and water until you reach a good consistency. Add desired amount of blue food coloring.

• Spread the purple icing on the cooled pop-tarts and allow to sit until hardened, about 5 minutes.
• Place the blue food coloring in a plastic bag, cut one of the corners off, and drizzle the blue icing over top of the purple icing.

Recipe Variations

More Flavorful Fillings:
Try mixing in a teaspoon of lemon zest or a splash of vanilla extract to the wild berry filling to add extra brightness.

Nutty Additions:
Add finely chopped almonds or walnuts into the filling for added texture and a nutty flavor boost.

Gluten-Free Option:
Use a gluten-free flour blend suitable for pastries instead of wheat flour to accommodate dietary needs.

Troubleshooting Common Problems with this Recipe

Dough is Too Sticky
If your dough is sticking excessively, it might be too warm or too wet. Chill it longer in the fridge and lightly dust your work surface and rolling pin with freshly milled flour to manage stickiness without drying the dough out.

Filling Leaks During Baking
Make sure to seal the edges of your pop-tarts well by pressing with a fork and avoid overfilling. Brushing water along the edges before sealing also helps create a better barrier.

Crust is Tough Instead of Flaky
Don’t overwork the dough when mixing or rolling out—it’s okay if the butter isn’t fully incorporated as long as it’s in small chunks. Overhandling activates gluten and makes the crust tough rather than tender.

Pop-Tarts Puff Up Unevenly
Prick vent holes evenly on the top crust to allow steam to escape. Uneven holes can cause uneven puffing or bubbling in the pastry.

Filling is Too Runny
Cook down your berry filling on the stove to reduce it before assembling. 

Freezing & Storing Leftovers

Freezing:
Once completely cooled, wrap your pop-tarts individually in plastic wrap and place them in an airtight freezer bag. They freeze well for up to 2 months. To enjoy, thaw at room temperature or warm gently in the oven for a freshly baked feel.

Storing:
Store leftover pop-tarts in an airtight container at room temperature for up to 2 days or in the fridge for up to 5 days. Reheat in a toaster oven or microwave for a quick treat that tastes close to fresh-baked.

Extra FAQs

Can I use store-bought flour instead of freshly milled flour?
Yes, you can definitely use all-purpose flour from the store, though the flavor and texture will be a bit less rich compared to fresh milled.

Do I have to use wild berries, or can I use just one type of berry?
Using a single type of berry works fine and can simplify things, but a mix offers a more complex and balanced flavor profile.

How long do homemade pop-tarts need to bake?
Bake until the crust is golden brown and the filling is bubbling, usually about 20-25 minutes depending on your oven.

Can I make the dough ahead and freeze it?
Absolutely. You can prepare the dough, wrap it tightly, and freeze it for up to one month. Just thaw in the fridge before rolling out.

What is the best way to reheat pop-tarts?
Warming them in a toaster oven or regular oven is best to keep the crust crisp. Microwaving can be quicker but might soften the crust too much.
