These flaky rhubarb puff pastry tarts are golden, buttery, and filled with a tangy-sweet rhubarb compote and silky vanilla cream. Ready in under an hour and stunning enough for any occasion.

If rhubarb season catches you every year with a surplus of those tart, rosy stalks and not enough ideas, this recipe is about to become your new best friend. These rhubarb puff pastry tarts are everything a great seasonal bake should be: shatteringly flaky on the outside, lusciously creamy in the middle, and bright with that bold, tangy rhubarb flavor that no other fruit quite matches.
Think of them as the grown-up, bakery-worthy cousin of rhubarb pop tarts. Homemade, generous, and genuinely impressive with very little effort required.
The magic here is in the layers. You start with store-bought puff pastry, which does all the heavy lifting in the flaky department. Underneath the rhubarb sits a whisked vanilla cream cheese filling that acts as a buffer, keeping the pastry from getting soggy and adding a gentle richness that balances the tartness perfectly.
The rhubarb is cooked into a quick compote before it goes on the pastry. This step is important. Raw rhubarb releases a lot of water during baking and can make your tarts soggy and uneven. A few minutes on the stovetop transforms it into a thick, jewel-toned filling with concentrated flavor. Worth every second.
Chef's Tip: Keep your puff pastry cold right up until it hits the oven. Warm pastry loses its layered structure before baking. If it starts to feel soft or sticky while you are working, slide it onto the baking sheet and refrigerate for 10 minutes before adding your toppings.
For rhubarb pastry recipes like this one, the quality of your puff pastry matters more than people realize. All-butter puff pastry (rather than shortening-based) gives you a far richer flavor and better puff. It is worth seeking out at a good grocery store or specialty market.
Here is what makes this recipe so approachable even if you are new to working with puff pastry:
The whole process, from stovetop to oven, takes under an hour, making this one of the most rewarding rhubarb puff pastry recipes you will find for the time invested.
Variation Idea: For a strawberry rhubarb puff pastry version, swap half the rhubarb for hulled, chopped fresh strawberries and reduce the sugar by a tablespoon or two. The result is a little sweeter and every bit as beautiful.
Whether you are making these for a weekend brunch, a spring dinner party, or simply because your garden rhubarb needs to be used, this rhubarb tart puff pastry recipe delivers every time. Pull out your pastry sheet and let's get into it.

These flaky rhubarb puff pastry tarts are golden, buttery, and filled with a tangy-sweet rhubarb compote and silky vanilla cream. Ready in under an hour and stunning enough for any occasion.
Preheat your oven to 400 degrees F (200 degrees C). Line a large baking sheet with parchment paper.
In a small saucepan over medium heat, combine the rhubarb, 0.25 cup of the granulated sugar, lemon juice, and cornstarch. Cook, stirring frequently, for 6 to 8 minutes until the rhubarb softens and the mixture thickens into a jammy compote. Remove from heat and let cool completely.
In a medium bowl, beat the softened cream cheese with the powdered sugar and vanilla extract until smooth and fluffy. Add the cold heavy cream and continue beating until the mixture is thick and spreadable, about 2 minutes. Refrigerate until ready to use.
On a lightly floured surface, unfold or roll out the puff pastry sheet to about a 12x9-inch rectangle. Cut into 6 equal rectangles.
Score a 0.5-inch border around each pastry rectangle with a sharp knife, being careful not to cut all the way through. Prick the inner section several times with a fork.
Spread a generous spoonful of the vanilla cream filling inside the scored border of each rectangle, staying within the border.
Spoon the cooled rhubarb compote evenly over the cream layer on each tart.
Brush the pastry borders lightly with the beaten egg wash. Sprinkle coarse sugar over the borders and rhubarb filling if using.
Bake for 20 to 25 minutes, until the pastry is deeply golden, puffed at the edges, and crisp on the bottom. Let cool on the pan for 5 minutes before serving.
Serve these warm or at room temperature. A light dusting of powdered sugar right before serving adds a lovely finishing touch. For something a little more indulgent, a small scoop of vanilla ice cream or a dollop of lightly whipped cream alongside turns these into a full dessert.
Leftovers keep in the refrigerator for up to two days. Reheat in a low oven to revive the crispness of the pastry. These are best the day they are made, but honestly, they rarely last long enough to worry about storage.
