Lay a sheet of baking paper on bottom of slow cooker bowl (just to protect surface)
Fill slow cooker bowl with 2cm of water
Sit a suitably sized (oven proof) serving dish into the water bath in the slow cooker
I used an oven proof ceramic type dish approx 23cm long, 15cm wide and 7cm deep
Combine cream cheese, cream, sour cream, soup mix, bacon and tasty cheese in a mixing bowl and combine well
Transfer to the cooking dish
Cook on high for 1hr 30 mins, stirring once during cooking time to combine well as cheeses melt
Then sprinkle top with diced chives and mozzarella cheese and cook for an additional 15mins, still with tea towel trick in place
Carefully remove dish from slow cooker, wipe the bottom that is wet, then serve straight to the table
