Step‑by‑Step Instructions for White Peach Mascarpone Tart
Step 1: Prepare Vanilla Pastry Cream
In a medium saucepan, heat 2 cups of whole milk over medium heat until steaming, then stir in 2 teaspoons of vanilla bean paste. In a separate bowl, whisk together ½ cup of white sugar, ¼ cup of cornstarch, and 4 egg yolks until smooth. Gradually mix in the hot milk, return the mixture to the saucepan, and cook over medium heat for about 5-7 minutes, stirring constantly until thickened. Strain through a sieve into a bowl and let it chill in the refrigerator.
Step 2: Make Poached Peaches
For the poaching liquid, combine 1 cup of sugar, 1 cup of Chardonnay, 1 teaspoon of vanilla extract, ¼ cup of honey, 2 tablespoons of lemon juice, and the zest of 1 lemon in a medium saucepan. Bring to a simmer over medium heat. Carefully add 4 firm ripe peaches, poaching them for about 4 minutes on each side until tender. Remove the peaches and allow them to cool in the liquid. Meanwhile, reduce the poaching liquid down to a syrupy consistency for about 10-15 minutes.
Step 3: Bake Puff Pastry
Preheat your oven to 400°F (200°C). Roll out a sheet of puff pastry on a lightly floured surface to fit your tart pan, gently pressing it into the pan, and trimming any excess. Prick the base with a fork and place a piece of parchment paper over the pastry, filling it with pie weights or dried beans. Bake for 20-25 minutes until golden and crispy. Once baked, remove the parchment and let the crust cool completely before adding the filling.
Step 4: Whip Mascarpone Diplomat Crème
In a large bowl, combine 1 cup of mascarpone, 1 cup of heavy cream, and ¼ cup of powdered sugar. Using an electric mixer, whip the mixture on medium-high speed until soft peaks form, taking about 3-5 minutes. Once the pastry cream is cold, gently fold it into the whipped mascarpone until fully combined, creating a luxurious diplomat crème that’s both light and creamy.
Step 5: Assemble Tart
Spread the whipped mascarpone diplomat crème evenly over the cooled puff pastry crust, creating a smooth layer. Drizzle some of the reduced poaching syrup on top for added flavor and shine. Finally, elegantly arrange sliced poached peaches and fresh raspberries over the cream, creating a vibrant display. Your stunning White Peach Mascarpone Tart is now ready to delight!

Make Ahead Options
These White Peach Mascarpone Tarts are perfect for busy home cooks looking to save time! You can prepare the vanilla pastry cream and poached peaches up to 24 hours in advance, allowing the flavors to meld beautifully. Store the pastry cream in the refrigerator, ensuring it’s completely chilled before folding it into the mascarpone to maintain its luscious texture. Bake the puff pastry crust a few hours ahead of serving and let it cool completely before assembly. When you’re ready to impress your guests, simply whip the mascarpone diplomat crème, fill the tart shell, and top with poached peaches and fresh raspberries. This way, you’ll enjoy a stunning dessert with minimal last-minute effort!

White Peach Mascarpone Tart Recipe FAQs
What should I look for when selecting ripe peaches?
Absolutely! The ideal peaches for your tart should be firm yet slightly yielding to pressure, indicating ripeness. Look for peaches with a vibrant color and a sweet aroma. Avoid any fruits with dark spots all over or wrinkled skin, as they may be overripe.
How should I store the White Peach Mascarpone Tart?
You can store your tart in the refrigerator for up to 2 days. Just cover it loosely with plastic wrap to keep it fresh while allowing it to breathe. This prevents the cream from sticking while maintaining its lovely texture.
Can I freeze the tart for later use?
Yes! You can freeze the unassembled White Peach Mascarpone Tart for up to 3 months. Wrap the cooled puff pastry tightly in foil and place it in an airtight container. When you’re ready to enjoy, simply thaw it in the refrigerator overnight before adding the filling.
What if my pastry cream doesn’t thicken properly?
Don’t worry! If your pastry cream doesn’t thicken as expected, it may need a little more cooking. Return it to the heat, stirring constantly for a couple of minutes until it reaches the desired consistency. Make sure to keep the heat medium-low to prevent burning.
Is this tart suitable for those with dairy allergies?
Unfortunately, the White Peach Mascarpone Tart contains dairy ingredients, so it’s not suitable for individuals with dairy allergies. However, you can explore alternative ingredients like coconut cream or cashew cream as substitutes to create a dairy-free version, keeping in mind that the taste and texture will differ a bit.
How do I ensure my puff pastry is crispy?
To achieve that delightful flaky texture, ensure that the puff pastry is not overcrowded in the pan and that you prick the base with a fork before baking. Weigh down the pastry with parchment paper and pie weights to prevent it from puffing too much. Keep an eye on it while baking to achieve a beautiful golden crust!
