What Are Rhubarb Puff Pastries With A Mascarpone Cream Filling?
Rhubarb Puff Pastries with a Mascarpone Cream Filling is a light, bakery-style dessert made with flaky puff pastry layered with a creamy, lightly sweet mascarpone filling and topped with tart rhubarb.
At its core, it’s all about contrast and balance. The puff pastry bakes into crisp, golden layers, while the mascarpone creates a soft, rich center that’s subtly flavored with vanilla and warm spices. The rhubarb adds a bright, slightly tangy note that keeps the dessert from feeling too heavy or overly sweet.

Because of that balance, it works beautifully for both casual moments and more intentional gatherings—something you can serve when you want a dessert that feels thoughtful, seasonal, and quietly impressive.

Shop What I Use: Rhubarb Puff Pastries with a Mascarpone Cream Filling
1.5 Biscuit Cutter
A 1.5-inch biscuit cutter is the perfect tool for shaping pastry rounds with clean, even edges, giving your rhubarb puff pastries a polished bakery-style look. It makes prep quicker, keeps each piece uniform, and helps create that beautiful presentation that makes homemade pastries feel extra special.
Wire Whisk
A good wire whisk is essential for creating that silky-smooth mascarpone cream filling. It blends ingredients effortlessly, giving you a light, airy texture without overmixing.
Parchment Paper
A reliable parchment paper is a must when working with delicate puff pastry. It prevents sticking, ensures even baking, and makes cleanup effortless—so your pastries come out perfectly golden every time.
How To Make Rhubarb Puff Pastries with a Mascarpone Cream Filling
1
On a cold surface working quickly, cut your puff pastry into 3-inch squares. Using a 1.5” biscuit cutter, cut a hole in one of the pieces of puff pastry.
2
Mix the mascarpone, egg, sugar, cinnamon, nutmeg, milk, and vanilla extract in a bowl. Whisk to combine thoroughly.
3
Place a pastry puff square on the parchment paper and carefully ladle about 1 tbsp of mascarpone mix into the center. Layer on your rhubarb slices neatly, being certain to leave about ¼ inch on each side of the pastry.
4
Place the holed pastry puff on top of the rhubarb, making a little window for the rhubarb to peek through. Firmly press the puff pastry sides together to form a solid sealed edge.
5
Ladle another tbsp of mascarpone mix on top of the rhubarb inside the window, spreading evenly, then garnishing with powdered sugar.
6
Bake for 15–18 minutes, or until the puff pastry is deeply golden, crisp, and fully puffed. Remove from the oven and allow to cool slightly before dusting with powdered sugar.

Rhubarb Puff Pastries with a Mascarpone Cream Filling
Ingredients
- 1 pack high-quality puff pastry, thawed according to packaged directions
- 2-3 pcs large stalks rhubarb, 36 inches, sliced into 2.5-inch strips long ways
- ⅔ cup mascarpone
- 1 pc egg
- 3 tbsp sugar
- 1 tsp cinnamon powder
- ⅛ tsp nutmeg
- ¼ tsp vanilla extract or vanilla bean paste
- ½ cup milk
- powdered sugar for garnish
Instructions
- Preheat the oven to 400°F (or 204 C) and line two non-rimmed cookie sheets with parchment paper.
- On a cold surface working quickly, cut your puff pastry into 3-inch squares. Using a 1.5” biscuit cutter, cut a hole in one of the pieces of puff pastry. Each pastry will have two pieces of separate puff pastry, one square one as the base and one holed one as the top.
- Mix the mascarpone, egg, sugar, cinnamon, nutmeg, milk, and vanilla extract in a bowl. Whisk to combine thoroughly.
- Place a pastry puff square on the parchment paper and carefully ladle about 1 tbsp of mascarpone mix into the center. Some may spill over the edge, but that’s okay. Layer on your rhubarb slices neatly, being certain to leave about ¼ inch on each side of the pastry.
- Place the holed pastry puff on top of the rhubarb, making a little window for the rhubarb to peek through. Firmly press the puff pastry sides together to form a solid sealed edge.
- Ladle another tbsp of mascarpone mix on top of the rhubarb inside the window.
- Repeat until all pieces are assembled. This is easiest if you do each step for the entire batch you make instead of doing one at a time.
- Bake for 15–18 minutes, or until the puff pastry is deeply golden, crisp, and fully puffed. Remove from the oven and allow to cool slightly before dusting with powdered sugar.
Variations To Try
This recipe is incredibly adaptable depending on what you have or the season you’re in.
- Strawberry Rhubarb: Add thin slices of strawberry for a slightly sweeter variation.
- Berry Blend: Replace rhubarb with raspberries or blackberries for a softer, jam-like texture.
- Citrus Twist: Add lemon zest to the mascarpone for a brighter finish.
- Almond Finish: Sprinkle sliced almonds on top before baking for added texture.
These small changes allow you to revisit the recipe throughout the year without it ever feeling repetitive.
What to Serve With Rhubarb Puff Pastries with a Mascarpone Cream Filling
These pastries work best as part of a simple, elevated pairing:
- Vanilla ice cream or whipped cream for added richness
- Coffee or espresso for balance
- Black tea or Earl Grey to complement the spices
- Sparkling wine or Prosecco for a light, celebratory feel
Pro Tips For The Best Rhubarb Puff Pastries
- Keep your puff pastry cold at all times
This is the most important step. If the pastry gets too warm, it won’t puff properly in the oven. Work quickly and chill it again if needed before baking. - Don’t overfill the center
It’s tempting to add more mascarpone, but too much filling can cause leaking and prevent the pastry from rising evenly. - Pat your rhubarb dry
If your rhubarb is very juicy (especially if frozen), gently pat it dry to avoid excess moisture that can make the pastry soggy. - Seal the edges well
Press firmly around the edges so the top layer stays in place and the filling doesn’t escape while baking. - Look for color, not just time
Bake until the pastry is deeply golden and fully puffed—this ensures it’s crisp and cooked through, not doughy inside. - Let them cool slightly before dusting sugar
If you add powdered sugar too early, it will melt. Let the pastries cool for a few minutes so you get that clean, bakery-style finish.

Shelf Life & Storage Tips
If you happen to have leftovers, they store surprisingly well.
Store: Keep in an airtight container in the refrigerator for up to 2 days
Reheat: Warm in the oven at 300°F for 5–7 minutes to bring back the crisp, flaky texture
Avoid: Microwaving, as it will soften the pastry and take away that golden crispness
Best Enjoyed: Fresh the day they’re baked for the best texture and flavor
