Ingredients
  

Base
  • 150 g biscuits crushed
  • 50 g butter melted
  • 3 –4 tablespoons milk
Filling
  • 250 ml sour cream
  • 250 g mascarpone cheese
  • 2 tablespoons Nutella
Topping
  • 3 tablespoons Nutella

Method
 

  1. Combine crushed biscuits, melted butter, and milk until evenly mixed. Press firmly into the bottom of a 20 × 20 cm pan (use the back of a spoon or a glass). Refrigerate while you make the filling.
  2. Whisk sour cream until smooth and slightly airy. Add mascarpone and 2 tablespoons Nutella, then whisk until creamy and semi-solid.
  3. Spread filling evenly over the chilled base. Smooth the top and refrigerate for 1 hour to set.
  4. Melt 3 tablespoons Nutella gently over a steamer until smooth and pourable. Pour over the set filling and spread evenly.
  5. Refrigerate for 3–4 hours, or until fully set. Slice into bars and serve chilled.

Notes

  • Use full-fat mascarpone and sour cream for best texture and stability.
  • Let Nutella come to room temperature before mixing for a smoother filling.
  • For clean slices, wipe the knife between cuts.
  • Store covered in the refrigerator for up to 3 days.
