- Line a non-stick loaf tin with cling film so that the inside is covered and the cling film hangs over the edges.
- Put the peanut butter into a small non-stick saucepan and heat over a low heat, stirring occasionally, for 2-3 minutes to soften. Tip into the loaf tin and spread out in an even layer. Pop into the freezer to chill whilst you whisk the cream.
- Pour the double cream, caramel condensed milk and a pinch of salt into a mixing bowl and whisk into soft peaks with a hand blender. Pour over the peanut butter and set in the fridge overnight.
- When you are ready to serve, melt the chocolate in a small heatproof bowl over a pan of simmering water. Place a serving plate over the ice cream and flip it out. Drizzle the chocolate over the top and add the hazelnuts if using. Slice up and serve immediately.
