  • 9 inch / 23 cm diameter springform tin




  • 400 g / 14.1 oz sugar-free chocolate or dark chocolate (85% cocoa solids minimum)
  • 8.8 oz / 250g mascarpone cheese room temperature
  • 4 tbsp powdered sweetener or to taste
  • 14 oz / 400g cream cheese room temperature
  • 1 tsp vanilla extract
  • 2 tbsp heavy cream 30 ml
  • Pinch of sea salt


  • cup heavy cream 160 ml
  • 1.5 tbsp unsalted butter or coconut oil 22g
  • 4.2 oz / 120 g sugar-free chocolate or dark chocolate (at least 85% cocoa solids)
  • optional tiny pinch of salt


  • 1 square of dark chocolate grated (10g)



  • Preheat the oven to 320F / 160C / 140 fan.
  • Mix the almond flour and butter in a bowl to form a dough. Use parchment paper to line the bottom of a 9 inch / 23cm loose bottom cake tin or springform pan and grease the sides to prevent sticking. Press the mix into the base. Bake for 20 - 25 minutes until slightly golden. Remove from the oven and allow to cool.


  • Place the sugar free chocolate chips (or dark chocolate) in a heatproof bowl over a pan of hot water. Simmer on a low heat until melted, stirring occasionally, until glossy and smooth.
  • Remove the bowl from the heat and allow to cool slightly.
  • Whisk the mascarpone, cream cheese, heavy cream, vanilla and a pinch of salt together in a bowl using an electric whisk until thick but don’t over beat. Slowly pour in the melted chocolate and fold in with a spatula to combine. If using an electric whisk, use a slow setting and don’t over-beat the filling or it will go stiff. Adjust the sweetness to taste.
  • Spoon the chocolate mix onto the base and smooth the top with a spatula.
  • Chill in the fridge for at least 3 - 4 hrs or overnight until set.


  • Heat the cream and butter / coconut oil on a low heat until hot (but not bubbling). Turn off the heat and add the dark chocolate / sugar free chocolate chips and allow to stand for 3 - 5 minutes. Stir briskly with a balloon whisk until glossy and smooth.
  • Spread over the top of the cheesecake and top with grated chocolate. Option to put the cake in the fridge if you prefer a set ganache.



Serve with a drizzle of cream, Greek yoghurt, coconut yoghurt or sugar free vanilla ice cream.
Storage: Fridge for up to 4 days or freezer for 2 months and defrosted at room temperature
You can serve this cake straight from the fridge or leave on the counter for 1 hour to soften the frosting. 
Net carbs 7.2g per 1 slice of 16. As this cake is very filling, you could consider cutting into 20 servings. Then, 1 slice would be 331 calories, 14.2g total carbs and 5.8g net carbs.  
FYI - if you cut into 20 slices and used 85% chocolate instead of sugar free chocolate chips, nutrition changes to 366 calories, 7.3g net carbs per slice and 5.3g sugar.
