What Is a Puff Pastry Walnut Tart?

A puff pastry walnut tart is a bite-sized pastry that combines the light, flaky texture of puff pastry with a rich and gooey walnut filling. The base is made from puff pastry sheets, which puff up beautifully in the oven, and the filling is a sweet, nutty mixture of walnuts, butter, brown sugar, and a hint of vanilla. Combining them creates the reliable contrast between crackly layers and the rich filling!

These tarts are ideal for holiday parties, weekend gatherings, or even a solo indulgence with a steamy cup of coffee. And they’re so simple to make, you’ll be in and out of the kitchen in no time!

Ingredients You Need

Frozen Puff Pastry Sheets – We love using these because they bake into beautifully crisp and flaky layers. Be sure to thaw them before starting.
Walnuts – Roughly chop these for a nutty crunch in every bite. Use fresh walnuts for the finest flavor.
Unsalted Butter – Softened butter helps create a rich and silky filling. Choose unsalted so you can control the saltiness.
Brown Sugar – Brown sugar adds a deep caramel-like sweetness to the filling.
Corn Syrup – This adds a smooth, glossy texture to the filling and helps bind everything together.
Heavy Cream – A splash of cream gives the filling a silky richness.
Egg – Whisked egg not only adds richness to the filling but also helps the puff pastry achieve a gorgeous golden brown finish.
Vanilla Extract – Vanilla adds a warm, sweet aroma to the filling. Opt for pure vanilla extract if possible.
Salt – Just a pinch balances the sweetness and brings out the flavors of the filling.

How to Make a Puff Pastry Walnut Tart

Make the filling. Melt the butter in a saucepan before adding the brown sugar, corn syrup, cream, egg, vanilla, walnuts, and salt. Cook until the mixture begins to thicken. Then, take the pan off the stove to allow the filling to cool just a bit.
Shape the pastry. Using a rolling pin, roll out the thawed puff pastry sheets before slicing them into rectangles. Place them in each of the wells of the prepared muffin tin.
Fill the cups. Transfer the walnut mixture evenly into the pastry cups.
Brush and bake. Use a pastry brush to apply the egg wash to the edges of the puff pastry. Place the pan in the oven and bake until the pastry is crisp and browned and the filling is bubbly.
Cool and serve. Allow the tarts to cool in the pan briefly before removing them from the pan to cool on a wire rack. Serve the tarts either warm or at room temperature.

Variations

Chocolate Chips – Stir a handful of mini chocolate chips into the filling for an extra layer of indulgence.
Pecans – Swap walnuts for pecans for a slightly sweeter and buttery flavor.
Sea Salt – Add a sprinkle of flaky sea salt on top after baking for a sweet-salty twist.
Spices – Mix in cinnamon or nutmeg to the filling for warm, aromatic flavors.
Maple Syrup – Substitute pure maple syrup for some or all of the corn syrup.
Dried Fruits – Include dried cranberries or raisins for a chewy, tart addition..

Can I Store Leftovers?

If you store leftovers, the puff pastry may lose some of its crispiness, but the flavors are still absolutely memorable.

Refrigerate in an airtight container or wrapped in plastic wrap for up to three days.

You can freeze the tarts for up to one month. Reheat them in the oven to bring back their crisp texture.
