Blackberry Lemon No-Bake Tart

Ingredients

For the Crust

• 2 cups fine graham cracker or vanilla wafer crumbs
• 6 tablespoons unsalted butter, melted
• 2 tablespoons granulated sugar
• 1/8 teaspoon fine salt

For the Lemon Filling

• 8 ounces cream cheese, softened
• 1 cup mascarpone cheese, chilled
• 3/4 cup powdered sugar
• 2 tablespoons finely grated lemon zest
• 1/3 cup fresh lemon juice
• 1 teaspoon vanilla extract
• 1 cup cold heavy cream

For the Topping

• 2 1/2 cups fresh blackberries
• 1 tablespoon seedless blackberry jam, warmed and cooled
• Fresh mint leaves
• Additional lemon zest

Substitutions

• Replace blackberries with raspberries or a mixed berry topping, keeping the fruit dry so the filling remains clean and firm.
• Use all cream cheese in place of mascarpone; the result will be tangier and slightly firmer.
• Use gluten-free graham crackers or vanilla cookies for the crust, checking that the crumbs absorb the butter before pressing.

Instructions

Step 1: Form the crust

Mix the crumbs, melted butter, sugar, and salt until the texture resembles wet sand. Press firmly across the bottom and up the sides of a 9-inch tart pan with a removable base.

Step 4: Whip and fold

Whip the cold heavy cream to medium-stiff peaks in a separate bowl. Fold it into the lemon mixture in three additions to keep the filling light.

Step 5: Fill and set

Spread the filling into the chilled crust and smooth the top. Refrigerate for at least 4 hours, or until the center is firm enough to slice cleanly.

Step 6: Decorate the tart

Toss the blackberries very gently with the cooled jam for a light gloss. Arrange them over the tart, then add mint and lemon zest immediately before serving.

How to Store Leftovers

• Cover the tart loosely without touching the berries and refrigerate it promptly.
• Use within 3 days for the best crust and berry texture.
• Store extra berries separately and add them to individual slices rather than crowding the tart during storage.

Serving Leftovers

• Do not reheat this dessert. Serve it directly from the refrigerator or let a slice stand for 5 minutes for a softer filling.
• If the tart has been frozen, thaw it overnight in the refrigerator while still covered.
• Keep the tart chilled during outdoor service and return it to refrigeration within 2 hours.

Serving Ideas

• Unsweetened iced tea
• Fresh berries on the side
• A small spoonful of lightly whipped cream
• Coffee or espresso

Common Mistakes to Avoid

• Adding wet berries, which streak the filling and soften the crust.
• Using cold cream cheese, which leaves visible lumps.
• Under-chilling the tart before removing the pan ring.
• Overbeating mascarpone, which can become grainy or loose.
