In separate bowls microwave your chocolates as outlined on packaging (aprox 3 mins but check after 1 min each time). Stir the peanut butter into your white chocolate.

Drop spoonfuls of chocolate alternately onto a baking sheet covered in wax (or parchment) paper. Lightly pull chocolate into "logs" so that it goes the length of your sheet. Swirl gently with a knife so you get the marbled look.

It doesn't need to look perfect! It is meant to have a nice swirl pattern to it, have fun with it!

Sprinkle with chopped nuts and cranberries and chill for 1 hour.

Break into small pieces and keep refrigerated until ready to serve
