- 1 (1/4-oz.) packet gelatin
- 15 oz. fresh blackberries, for puree

- 1 Tbsp. orange juice
- Remaining 1/4 tsp. kosher salt
- 2/3 cup heavy whipping cream
- 2/3 cup condensed milk
- 6 oz. mascarpone, room temperature
Topping (Optional)
- 1 Tbsp. reserved blackberry puree
- 1/4 cup mini Oreos
- Remaining blackberries for garnish
Yield: Serves 8–10, depending on slice size
Tools & Equipment Needed
- 9-inch tart pan
- Large mixing bowls
- Small saucepan
- Blender or food processor
- Fine-mesh sieve
- Stand mixer with whisk attachment (or handheld mixer)
- Rubber spatula
- Measuring cups and spoons
Optional: Offset spatula for smooth spreading and clean presentation
Step-by-Step Instructions
Follow these steps closely to achieve a beautifully layered, no-bake tart.
Step 1: Prepare the Oreo Crust
- In a large bowl, combine finely crushed Oreos, melted butter, and 1/4 tsp. kosher salt.
- Using the bottom of a measuring cup, press the mixture evenly into the bottom and up the sides of a 9-inch tart pan.
- Freeze until chilled, about 20 minutes. This will help the crust set and hold its shape.
Step 2: Dissolve the Gelatin
- In a small saucepan over medium heat, combine gelatin with 3 tablespoons water.
- Whisk frequently just until the gelatin dissolves completely, about 1 minute.
- Remove from heat and let cool slightly.
Step 3: Prepare the Blackberry Puree
- Blend 15 oz. fresh blackberries in a blender until smooth.
- Strain 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 the puree for the topping.
- Add orange juice, dissolved gelatin, and the remaining 1/4 tsp. salt to the rest of the puree, and stir to combine.
Step 4: Make the Mascarpone Whipped Cream
- In the large bowl of a stand mixer fitted with the whisk attachment (or a large mixing bowl with a handheld mixer), beat the heavy cream on medium-high speed until stiff peaks form.
- Slowly add condensed milk, continuing to beat until fully combined.
- Reserve 5 oz. of the whipped cream for the topping.
- On low speed, add the mascarpone and blackberry puree mixture to the remaining whipped cream, beating until fully incorporated and no white streaks remain.
Step 5: Assemble the Tart
- Pour the mascarpone blackberry filling into the chilled Oreo crust.
- Refrigerate for at least 1 hour, up to 2 hours, to allow the filling to set.
Step 6: Prepare Topping
- In a medium bowl, fold the reserved 1 tablespoon of blackberry puree into the reserved 5 oz. of whipped cream just until there are solid streaks of both cream and puree visible.
Step 7: Garnish and Serve
- Dollop the blackberry-streaked whipped cream in the center of the tart.
- Cut half of the remaining 2 oz. blackberries in half. Arrange the halved and whole berries over the cream.
- Sprinkle mini Oreos, if using, to complete the presentation.
Tips & Variations
- No food processor? Use resealable plastic bags and a rolling pin to crush Oreos.
- Berry color variation: Every batch of blackberries differs in color. Don’t be alarmed if the puree is darker or lighter—it won’t affect the flavor.
- Frozen blackberries: Avoid using them for this tart; frozen berries release water and can make the filling runny.
- Substitutions: Cream cheese can replace mascarpone for a budget-friendly option. Agar agar works as a vegan gelatin alternative—just follow the ratio carefully.
- Condensed milk: Slowly fold in to avoid deflating whipped cream. The gelatin ensures the filling sets properly.
Flavor Profile & Pairings
The tart delivers:
- Sweetness: From condensed milk and Oreos.
- Tanginess: From fresh blackberries.
- Creaminess: Mascarpone whipped cream provides a rich, smooth texture.
- Crunch: Oreo crust adds structural and textural contrast.
Suggested Side Pairings
- Fresh mint leaves for added freshness
- Extra berries on the side for a burst of natural sweetness
- Light dusting of powdered sugar for elegant presentation
