Peanut butter cheesecake

Method

• step 1

  Oil and line a 20cm round loose- bottomed cake tin with cling film, making it as smooth as possible. Melt the butter in a pan. Crush the biscuits by bashing them in a bag with a rolling pin, then stir them into the butter until very well coated. Press the mixture firmly into the base of the tin and chill.

• step 2

  Soak the gelatine in water while you make the filling. Tip the ricotta into a bowl, then beat in the peanut butter and syrup. Ricotta has a slightly grainy texture so blitz until smooth with a stick blender for a smoother texture if you prefer.

• step 3

  Take the soaked gelatine from the water and squeeze dry. Put it into a pan with the milk and heat very gently until the gelatine dissolves. Beat into the peanut mixture, then tip onto the biscuit base. Chill until set.

• step 4

  To freeze, leave in the tin and as soon as it is solid, cover the surface with cling film, then wrap the tin with cling film and foil.

• step 5

  To defrost, thaw in the fridge overnight.

• step 6

  To serve, carefully remove from the tin. Whisk the cream with the sugar until it holds its shape, then spread on top of the cheesecake and scatter with the peanut brittle.
