Strawberry Rhubarb Pop Tarts
Ditch the cardboard box and bake these incredibly flaky, buttery Strawberry Rhubarb Pop Tarts from scratch, featuring a thick, sweet-tart fruit filling and a sweet vanilla glaze.
- Pre-cooking the strawberry-rhubarb filling removes excess moisture, preventing a soggy bottom crust.
- Using cold, cubed butter and a touch of acid relaxes the gluten, ensuring a tender, flaky pastry.
- A simple egg wash seal acts as a waterproof barrier, keeping the sweet-tart filling locked inside.
I still remember the exact sound of my cheap plastic rolling pin cracking against the kitchen counter three summers ago when I tried to force cold butter into submission.
I was determined to recreate those foil-wrapped toaster pastries of my childhood, but my first attempt yielded a sad, soggy rectangle that leaked purple goo all over my baking sheet. It was a complete disaster, mostly because I rushed the dough and treated the pastry like a basic pie crust.
Most homemade pop tart recipes fail because they ignore the physics of steam.
When you bake a pastry, the water in the butter evaporates, creating pockets of air that lift the flour layers. If your filling is too watery—which fresh strawberries and rhubarb notoriously are—that excess moisture turns the bottom crust into a mushy, waterlogged mess before the starch gelatinization can lock the structure in place. This is why mastering the dough texture is just as critical as it is when making flaky Croatian Croissants.
The fix is incredibly simple.
We are going to cook down our fruit into a thick, concentrated paste first, almost like a quick version of my favorite vanilla rhubarb jam. This drives off the excess water while concentrating those bright, tangy flavors so they pack a punch without ruining our flaky layers.
If you have ever struggled with pastry dough, trust me on this one.
Your forearms might ache a little from rolling, but the payoff is absolutely perfect.
Strawberry Rhubarb Pop Tarts
Ingredients
- 2 1/2 cups (312g) all-purpose flour
- 1 teaspoon Diamond Crystal kosher salt (or 1/2 tsp fine table salt)
- 1 tablespoon granulated sugar
- 1 cup (226g) unsalted butter, cold and cubed
- 1/2 cup ice water (plus more if needed)
- 1 large egg (for egg wash)
- 1 cup fresh strawberries, finely chopped
- 1 cup fresh rhubarb, finely chopped
- 1/4 cup granulated sugar (for filling)
- 1 tablespoon cornstarch
- 1 teaspoon lemon juice
- 1 cup powdered sugar
- 2 tablespoons heavy cream
- 1/2 teaspoon vanilla extract
- 1 tablespoon freeze-dried strawberries, crushed (optional)
Directions
- In a large bowl, whisk together the flour, salt, and sugar. Add the cold, cubed butter and use your fingers or a pastry cutter to work the butter into the flour until it resembles coarse crumbs with some pea-sized pieces remaining.
- Drizzle in the ice water, one tablespoon at a time, mixing gently with a fork until the dough just starts to hold together. Divide the dough into two equal discs, wrap in plastic, and refrigerate for at least 1 hour.
- While the dough chills, make the filling. Combine the chopped strawberries, rhubarb, sugar, cornstarch, and lemon juice in a small saucepan over medium heat. Cook, stirring frequently, for 8 to 10 minutes until the fruit breaks down and thickens into a jam-like consistency. Let cool completely.
- Preheat your oven to 375°F (190°C) and line a large baking sheet with parchment paper.
- Roll out one disc of dough on a lightly floured surface into a large rectangle, about 9x12 inches. Cut into 8 equal rectangles (about 3x4.5 inches each) and place them on the prepared baking sheet. Repeat with the second disc of dough.
- Spoon about 1 tablespoon of the cooled filling onto the center of the rectangles on the baking sheet, leaving a 1/2-inch border around the edges. Brush the borders lightly with beaten egg wash.
- Place the remaining dough rectangles over the filling. Use a fork to crimp the edges tightly to seal. Poke a few holes in the top of each pastry with a toothpick to let steam escape.
- Brush the tops of the pastries with the remaining egg wash. Bake for 20 to 25 minutes, or until the pastries are golden brown. Transfer to a wire rack to cool completely before glazing.
- Whisk together the powdered sugar, heavy cream, and vanilla extract until smooth. Spread the glaze over the cooled pop tarts and top with crushed freeze-dried strawberries if desired.
Notes
- Salt Conversion: This recipe specifies Diamond Crystal kosher salt. If you are using fine table salt, cut the measurement in half (use 1/2 teaspoon) to avoid an overly salty pastry.
- The Science of Thickeners: Cornstarch is essential here because it binds the free water released by the strawberries and rhubarb during baking, preventing the filling from boiling over and breaking the pastry seals.
- Workflow Warning: Never place warm filling onto cold pastry dough. The heat will melt the butter pockets in the dough, destroying your chances of getting a flaky rise in the oven.
- Storage Behavior: The sugar glaze will naturally draw moisture from the pastry over time. If you plan to make these ahead, store them unglazed and apply the glaze just before serving.
Serving Suggestions
These pastries are best enjoyed slightly warm when the crust is at its absolute flakiest. If you want to make a fun breakfast spread, try pairing them with some of these delicious options:
- Serve alongside a hot cup of coffee or a creamy cherry vanilla latte.
- Plate them with a scoop of vanilla bean ice cream for an easy, elegant dessert.
- Add them to a weekend brunch spread next to some savory baked mushroom egg cups.
- Pack them in school lunches as a special, nostalgic treat.
- If you love oversized bakes, try making a giant frosted pop tart instead of individual ones.
Storage and Reheating
Store any leftover glazed pop tarts in an airtight container at room temperature for up to three days. Keep in mind that the sugar glaze draws moisture from the air, which will gradually soften that beautifully crisp pastry crust over time.
They still taste incredible, just less crunchy.
For longer storage, freeze the unglazed baked pastries on a sheet pan before transferring them to a freezer bag for up to three months.
When you are ready to eat, pop them directly into a toaster oven at 350°F (175°C) for about five to seven minutes to restore their flaky texture. Apply the glaze fresh right before serving for the absolute best experience.
Ingredient Substitutes
If you don't have all the exact ingredients on hand, don't worry. Here are some reliable swaps that won't ruin your bake:
- Rhubarb: Swap with equal parts cranberries or raspberries for a similar tart profile.
- Cornstarch: Use arrowroot powder or tapioca starch in a 1:1 ratio to thicken the filling.
- Heavy Cream: Milk or dairy-free almond milk works perfectly fine for the glaze, though it will be slightly thinner.
- All-Purpose Flour: A 1:1 gluten-free baking flour blend can be used, though the pastry will be slightly more delicate to roll.
There is something deeply satisfying about pulling a tray of these golden, hand-crimped pastries out of your own oven. They might not look as perfectly uniform as the machine-made ones from a box, but the buttery, flaky layers and the bright, jammy filling are lightyears ahead of anything you can buy.
