By crikey this is good – I have been making ice cream variations for ages, and this one just went to the top of the favourites list.
150 grams dark chocolate (72% cocoa), chopped into 1cm chunks
1⁄4 cup Frangelico
1 tablespoon dark cocoa
395-gram tin sweetened condensed milk
1⁄2 cup boysenberry jam
1⁄2 cup chopped toasted hazelnuts or almond flakes
1.5 litre-capacity freezer-safe container.
Heat half the cream in a small microwave-safe jug or on the stovetop until simmering. Add the chocolate chunks and leave to sit for 1 minute.
Whisk until smooth, if necessary, reheating very briefly. Set aside until cool. Add the Frangelico to the chocolate and whisk to combine.
Whip the remaining cream to soft peaks, add the cocoa and sweetened condensed milk and whisk until smooth.
Completely fold in the cooled chocolate and pour into the container. Freeze for 3 hours then drop in blobs of jam and 1⁄2 of the hazelnuts and swirl through gently. Freeze a further 4 hours or overnight before serving. Top with the remaining hazelnuts to serve.
