Ingredients

Instructions

  1. Step 1: Preheat your oven to 350°F. Place 24 Oreo cookies (with filling) into a food processor and pulse until finely ground. Mix in 6 tbsp melted unsalted butter until the mixture resembles wet sand.
  2. Step 2: Press the Oreo crust mixture firmly into the bottom and up the sides of a 9-inch tart pan. Bake for 10 minutes until set and fragrant. Remove from oven and let cool.
  3. Step 3: In a medium saucepan, heat 1 cup heavy cream over medium heat until it just begins to simmer, about 3 minutes. Remove from heat and pour over 8 oz bittersweet chocolate chips in a heatproof bowl. Let sit for 2 minutes, then stir gently until smooth and glossy.
  4. Step 4: Pour the chocolate ganache into the cooled Oreo crust and smooth the top with a spatula. Refrigerate for at least 3 hours until set.
  5. Step 5: For the topping, whip 1 cup unsweetened heavy whipping cream with 2 tbsp powdered sugar and 1 tsp vanilla extract using an electric mixer on medium-high speed until soft peaks form, about 3-4 minutes.
  6. Step 6: Dollop or pipe the whipped cream over the chilled ganache tart just before serving to contrast the rich chocolate with light creaminess.
