Place all chocolate and condensed milk in slow cooker.
Place slow cooker on high and stir with a metal spoon every 10 to 15 minutes, for around 1 to 1.5 hours.
When chocolate is nearly melted, stir in 3/4 of the diced, dried strawberries (save some for topping).
If mixture becomes too think, add a tablespoon of milk at a time and stir briskly after each addition, until smooth.
When ingredients are combined and a thin crust begins to form between stirs, pour mixture onto a tray, lined with baking paper.
Sprinkle remaining diced strawberries over the top.
Cover and place in fridge to set.
Enjoy!
