Whip the cream until soft peaks, add the condemned milk, milk powder (and I like to add little vanilla and salt) and whip until stiff peaks.
Melt the chocolate in a microwave in 20 second intervals, stirring, once smooth, set aside to cool.
Divide the whipped cream into two bowls. Add white chocolate to one bowl and dark chocolate to another bowl. Whisk bowl separately until combined.
Line a 9inch loaf tin with cling wrap generously, alternate scooping the dark and white chocolate, add dollops of raspberry jam as well, add pieces of the Franui and repeat.
Smooth out the top and cover with cling wrap. Place in the freezer for 6-8 hours.
Remove from the freezer, make off the cling wrap, place a platter on top and flip the tin over, gently remove the tin and peel off the cling wrap. Garnish with more Franui pieces, slice and serve.
