Gluten Free Sourdough Poptarts | Homemade Strawberry Poptarts

Gluten Free Sourdough Poptarts are a dream come true. I've been waiting years for this!

Gluten-free sourdough pie crust is stuffed with strawberry jam filling, baked until golden brown and flaky, then topped with a strawberry glaze. This gluten free poptart recipe is actually an improvement to their regular wheat counterparts. The crust is much thicker and has a crispy, buttery exterior. They may even be a touch like toaster strudel?

You'll need gluten-free sourdough discard to make homemade strawberry poptarts, preferably from a superfine brown rice or sorghum flour starter.

If you don't have a gluten-free sourdough starter, you'll first need to make one. Find out how with my guide: How to Make a Gluten Free Sourdough Starter.

Tips for making the Best Gluten Free Sourdough Poptarts:

Homemade strawberry poptarts are simple to make, but I do have a few tips to guarantee the best possible results:

• Chill the dough discs in the refrigerator for at-least 30 minutes before rolling it out and shaping into poptarts. The colder the dough the easier it is to work with. I also recommend working with one disc of dough at a time, leaving the other in the fridge until you need it.
• To buy myself time, I placed ice packs underneath of the cookie sheet with the shaped and stuffed poptarts. They stayed nice and cold while I finished shaping the rest. Alternatively, you can place the poptarts back in the refrigerator - just make sure your cookie sheet can fit.
• Prep your filling bowls and egg wash before stuffing the poptarts so that the process is streamlined.

• Roll each disc of dough into a rectangle about 10 x 11 and trim the edges to about 9 or 9.5 x 10. You can use the scraps of dough to fill in any corners or wavy edges. I also like to use the flat edge of my dough cutter to straighten up the edges. Each poptart should be about 5 inches in length x 3 to 3.5 inches in width once folded over.
• Brush the egg wash around the filling to help seal the jam inside of the poptart. Press firmly around the edges with a fork.
• Poke small holes in the tops of the poptarts to allow steam to escape. I did 4 holes with the small end of a chopstick.
• For a more sour flavor, you can ferment the dough (wrapped tightly) overnight in the refrigerator.

Ingredients for Gluten Free Sourdough Poptarts | Homemade Strawberry Poptarts:

For the Pie Crust:

• High quality gluten-free all purpose flour containing xanthan gum. I used Bob's Red Mill GF 1:1 Baking flour (the blue bag).
• Gluten free sourdough discard (the inactive portion from the starter) This recipe does best with cold discard straight from out of the fridge. I used between 1-2 weeks old.
• Unsalted butter. If using salted, omit the salt from the recipe.
• Milk
• Vinegar - either white vinegar or apple cider vinegar works fine here
• Granulated sugar
• Salt

Egg Wash:

• Egg
• Milk

Strawberry Filling:

• Natural strawberry jam (or any variety of jam such as blueberry, raspberry, mixed berry, etc.)
• Cornstarch, or arrowroot powder *This is to thicken the jam as it bakes so that it doesn't become runny.

Strawberry Glaze:

• Powdered sugar
• Natural strawberry jam (or any variety) *This gives the glaze a great natural color and flavor
• Milk

How to Make Gluten Free Sourdough Poptarts:

For the Pie Crust:

• Add the gluten-free flour, sugar, and salt to a large mixing bowl. Whisk together until well-combined.

• Add in the cubed, cold butter and use a dough cutter to work the butter into the flour until it resembles small peas. You can also grate the butter with a cheese grater.
• Add in the gluten free sourdough discard, vinegar, and 2-4 tablespoons of milk to the mixture and use a fork to incorporate into large crumbles. Switch to using your hands and press the dough together until there are no dry bits. Add additional milk 1-2 tablespoons at a time until the dough starts to come together to form a ball. I used 11 total tbsp.

• Divide the dough in half - measure on a kitchen scale to be accurate - and shape into smooth balls. Use the palms of your hands to press the dough balls into discs.
• Wrap the discs tightly in plastic wrap and chill for 30 minutes, or 2 hours - overnight, and up to 3 days. Chilling overnight can long ferment the dough to make it a little more sour.

For the Strawberry Filling:

• In a small bowl, mix the jam with the cornstarch until well combined.

• Set aside.

For the Egg Wash:

• Whisk together 1 egg and 1 tablespoon of milk in a small bowl.
• Set aside.

Rolling and Shaping the Gluten Free Sourdough Poptarts:

• Prep: Lightly flour the counter, or set out a large piece of parchment paper. Set out the bowls of egg wash and strawberry filling. Line a baking sheet with parchment paper (use a tray that can fit in the fridge). This is where the filled and shaped poptarts will rest. I recommend placing flat ice packs underneath of the tray to keep the poptarts cold.
• After having chilled for at-least 30 minutes, remove one of the dough discs from the refrigerator and set on the prepared surface.

• Set a piece of parchment paper over the disc and use a French rolling pin to roll the dough into a rectangle about 10 x 11 inches. Trim the edges to about 9 x 10. You can use the scraps of dough to fill in any corners or wavy edges. I also like to use the flat edge of my dough cutter to straighten up the edges.
• Cut the rectangle of dough into three 3-inch wide strips. Each poptart should be about 5 inches in length x 3 inches in width once folded over.
• Spoon 2 tablespoons of the strawberry jam filling on one end of each strip.
• Brush the egg wash around the jam. This helps seal the jam inside of the poptart.

• Fold the dry end of each strip over the end with jam.
• Press firmly around the edges with a fork to seal. Then, poke small holes in the top of each poptart to allow steam to escape. I made 4 holes with the small end of a chopstick.

• Place the shaped and filled poptarts on the prepared baking sheet.
• Repeat this process with any remaining strips and the other refrigerated disc of dough.
• Chill the poptarts for an additional 20 minutes to firm them up. You can skip this if you placed ice packs underneath the cookie sheet.
• Meanwhile, preheat the oven to 350 F.

• Just before baking, brush the tops of each poptart with the remaining egg wash. Bake for 22 to 30 minutes, rotating the pan halfway through, or until golden brown.

• Remove the tray from the oven, allow to cool for 5 minutes, then transfer to a wire cooling rack. Cool completely before glazing.

For the Strawberry Glaze:

• Whisk together all of the ingredients for the glaze (powdered sugar, jam, and milk) until smooth.

• Spoon over top of the cooled poptarts.
• Allow the glaze to set up for 30 minutes.

Equipment

You only need basic kitchen tools to make Homemade Strawberry Poptarts. I recommend:

• A dough cutter for measuring and cutting the poptarts. I used this tool A LOT for this recipe. It was especially helpful in straightening up the edges. Got wonky edges? Just slam this tool against it a few times, and bam, perfect poptarts.
• A basting brush or pastry brush for the egg wash.
• A large cookie sheet is helpful so you only have to bake one batch and be done.
• Flat ice packs were a godsend in this recipe. It kept the poptarts on the cookie sheet nice and chilled while I took forever and a day with my shaping. I am a really slow cook.
• You can use a Danish dough whisk instead of a fork when mixing up the dough.
• A kitchen scale is always a must when baking gluten-free.
• Parchment paper is always a must.
• I prefer a French rolling pin for rolling out gluten-free dough. The tapered ends makes it so there is less for the dough to stick to.
• Don't want to make a gluten-free starter from scratch? This Sourdough Starter Culture packet gives you a head start with a dehydrated gluten-free sourdough starter culture and directions to follow to maintain it for years to come. I love this website because there's also cheesemaking, yogurt, kombucha, and fermented vegetable kits. (Use the code WONDERS15X on Cultures For Health's website to get 15% off!) The GF starter is also available for purchase on Amazon here.

How to Store Gluten Free Sourdough Poptarts:

You can store these poptarts at room temperature for 2 to 3 days, or in the refrigerator for 5 days. The glaze will start to thin if left out at room temp.
