These flaky, golden pastries are filled with a tart-sweet rhubarb compote that bubbles up inside as they bake, creating pockets of joy that are impossible to resist.
The first time I made these, I had some leftover puff pastry in the freezer and a bundle of rhubarb from the farmers market. I simmered the rhubarb down into a quick filling and tucked it into pastry squares. What came out of the oven were these stunning little hand pies that were crispy on the outside, gooey on the inside, and bursting with flavor. Now, they're a regular treat every spring and summer.
Whether you're looking for a brunch dessert, a sweet snack, or a pretty addition to your afternoon tea, these Rhubarb Puff-Tart Pockets will bring a little sparkle to your day.

Ingredients You’ll Need
For the Filling:
- 2 cups rhubarb, chopped into small pieces
- ½ cup granulated sugar
- 1 tablespoon cornstarch
- 1 tablespoon lemon juice
- ¼ teaspoon vanilla extract (optional)
For the Pastry:
- 1 sheet puff pastry (store-bought or homemade, thawed if frozen)
- 1 egg, beaten (for egg wash)
- Powdered sugar (for dusting, optional)
Step-by-Step Instructions
- Make the Rhubarb Filling
In a small saucepan over medium heat, combine chopped rhubarb, sugar, cornstarch, and lemon juice. Stir frequently until the rhubarb breaks down and the mixture thickens, about 8–10 minutes. Remove from heat and stir in vanilla extract if using. Let cool completely. - Prepare the Puff Pastry
On a lightly floured surface, unfold or roll out the puff pastry sheet into a 10x10 inch square. Cut into 4 equal squares (or 6 rectangles if preferred). - Assemble the Pockets
Place a spoonful of the cooled rhubarb filling in the center of each square. Be careful not to overfill. - Seal the Edges
Brush the edges with beaten egg. Fold the pastry over to form a triangle or rectangle. Press the edges together and crimp with a fork to seal. - Chill Before Baking
Place the assembled pockets on a baking sheet lined with parchment paper. Chill in the refrigerator for 15–20 minutes to help them hold their shape. - Egg Wash and Bake
Preheat oven to 400°F (200°C). Brush the tops of the pastries with egg wash. Bake for 18–22 minutes, or until golden brown and puffed. - Cool and Dust
Let the pockets cool slightly on the baking sheet, then transfer to a wire rack. Dust with powdered sugar just before serving if desired.

Serving and Storage Tips
These pockets are best served slightly warm or at room temperature. They pair wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream.
Storage:
- Store leftovers in an airtight container at room temperature for up to 2 days.
- Reheat in a 300°F oven for 5–7 minutes to refresh the crispness.
- Not ideal for freezing after baking, but unbaked assembled pockets can be frozen and baked straight from the freezer.
Helpful Notes
- Don’t Overfill: Too much filling will cause leakage.
- Cool the Filling: Warm filling can make the pastry soggy and hard to seal.
- Vent the Tops: Cut a small slit in each top to allow steam to escape.
- Flavor Boost: Add a pinch of cinnamon or ginger to the filling for a spicy twist.
- Add Fruit: Mix in a few chopped strawberries or raspberries for a berry-rhubarb combo.
Frequently Asked Questions
- Can I make these with frozen rhubarb?
Yes, thaw and drain it first, and cook the filling a bit longer if needed. - Can I use homemade puff pastry?
Absolutely! It will take more time but tastes even more incredible. - Can I make these ahead?
You can make and refrigerate the filling and pastry squares ahead. Assemble and bake when ready. - Do I have to use an egg wash?
The egg wash gives them a glossy, golden finish but can be skipped or replaced with milk or cream. - Can I make mini versions?
Yes! Cut the puff pastry into smaller squares for bite-sized treats. Adjust baking time accordingly.
