Ingredients

Scale

Crust

  • 24 Oreos, finely crushed (about 9.5 oz.)
  • 5 tbsp. unsalted butter, melted and cooled
  • 1/4 tsp. kosher salt

Gelatin Mixture

  • 1 (1/4-oz.) packet gelatin
  • 3 tbsp. water

Blackberry Puree

  • 17 oz. fresh blackberries (about 3 cups), divided
  • 1 tbsp. orange juice
  • 1/4 tsp. kosher salt

Filling

  • 2/3 cup heavy whipping cream
  • 2/3 cup sweetened condensed milk
  • 6 oz. mascarpone cheese, room temperature

Topping (Optional)

  • 1/4 cup mini Oreos

Instructions

  1. Prepare the crust: In a large bowl, combine the finely crushed Oreos, melted butter, and 1/4 teaspoon kosher salt. Use the bottom of a measuring cup to evenly press the mixture into the bottom and up the sides of a 9-inch tart pan. Freeze the crust until chilled and firm, about 20 minutes.
  2. Dissolve the gelatin: In a small saucepan over medium heat, whisk together the gelatin packet and 3 tablespoons of water, stirring frequently until the gelatin completely dissolves, about 1 minute. Remove from heat and let it cool slightly.
  3. Make blackberry puree: In a blender, puree 15 ounces of the blackberries until smooth. Strain the puree through a fine-mesh sieve into a medium bowl to remove seeds, yielding approximately 1 1/2 cups of smooth puree. Set aside 1 tablespoon of this puree for the topping. To the remaining blackberry puree, add orange juice, dissolved gelatin, and remaining 1/4 teaspoon kosher salt; stir well to combine.
  4. Prepare whipped cream mixture: Using a stand mixer fitted with the whisk attachment or a handheld mixer, beat the heavy whipping cream on medium-high speed until stiff peaks form. Slowly add the sweetened condensed milk and continue beating until well combined. Reserve 5 ounces of this whipped cream mixture for the topping. On low speed, add the mascarpone cheese and blackberry mixture to the remaining whipped cream and beat until smooth with no white streaks.
  5. Assemble and chill: Pour the blackberry mascarpone filling into the chilled Oreo crust, spreading evenly. Refrigerate the tart for at least 1 hour and up to 2 hours to set.
  6. Prepare topping: In a medium bowl, gently fold the reserved 1 tablespoon blackberry puree into the reserved 5 ounces whipped cream until streaked but not fully blended, creating a marbled effect.
  7. Garnish and serve: Spoon dollops of the marbled blackberry whipped cream into the center of the tart. Cut half of the remaining 2 ounces of blackberries in half and arrange them along with the whole blackberries and optional mini Oreos on top of the cream for decoration.

Notes

  • Make sure the mascarpone is at room temperature to avoid lumps in the filling.
  • Press the Oreo crust firmly and evenly into the tart pan to prevent cracking during slicing.
  • The gelatin must be fully dissolved and slightly cooled before adding to prevent lumps in the filling.
  • For an extra fruity burst, use fresh blackberries rather than frozen for best flavor and texture.
  • This tart can be prepared a day in advance and stored covered in the refrigerator.
  • Optional mini Oreos add extra crunch and decoration but can be omitted for a gluten-free version by using gluten-free cookies in the crust and topping.
