  • 24 oreo cookies (264g)
  • 4.9 oz (140g) butter
  • 10.5 oz (300g) dark chocolate good quality
  • 6.1 oz (175g) marshmallows , cut into small pieces
  • ½ cup (110g) mascarpone cheese
  • 2 tablespoon strong espresso
  • cup (80ml) ⅓ cup water
  • 1 very small pinch smoked sea salt flakes (or regular)
  • unsweetened cocoa powder for dusting (optional)

Topping (opional)

  • 4 heaped tablespoon ricotta cheese
  • 2 tablespoon unsweetened cocoa powder
  • 3 tablespoon fine granulated sugar


  • First, melt half of the butter in a saucepan. Add the oreo cookies to a food processor (whole cookies including the white filling). Blitz the cookies to a fine crumb whilst adding the melted butter.
  • Add the crumbs to a lined cake tin (8.5 inch/22cm) and press it firmly with the back of a metal spoon to create a smooth, even layer. Place it in the fridge while you make the filling.
  • Cut the marshamallows into small pieces and brake up the chocolate into small chunks. Add them both to a large saucepan with the espresso, water and remaining half of the butter (cut into cubes).
  • Melt the mixture over a low/medium heat and stir the mixture until everything has completely melted. When there are only a few lumps of marshmallows left, turn the heat off and add the mascarpone. 
  • Stir the marscarpone into the chocolate mixture until combined and add a tiny pinch of sea salt.
  • If there are still a few lumps of marshmallows left then turn the heat back on for a few seconds and stir until melted.
  • Remove the chocolate cheesecake base from the fridge and pour the chocolate filling into the tin. Place it back in the fridge to set for at least 1 hour (preferably 2-3). Dust with unsweetened cocoa powder before serving (optional).

For topping (optional)

  • Add the ricotta to a mixing bowl and whisk until smooth and creamy. Add the sugar and sieve in the cocoa powder. Mix everything together, taste and add more sugar if necessary.
  • Add the mixture to a piping bag with a large star shaped nozzle. Pipe the frosting around the edge of the cheesecake and serve.



  • Try adding orange zest, mint, vanilla or your favourite flavourings into the chocolate mixture.
  • Replace the espresso with water if you don't want a coffee flavour.
  • Overall time excludes chilling time.
  • Can be frozen. Cut into individual portions before freezing, wrap in baking parchment and place in a sealed container. Let it thaw completely before serving.

Equipment Used

  • An 8.5inch/22cm cake tin (these come in a set of 3. They are great non-stick pans that I've used for a long time).
  • My very favourite pink spatula (I use this for everything from making making sauces, stews, baking and scraping every last drop of pesto out the food processor!)
