Stir in the chopped chocolate.

Step 3

In a separate small bowl, mix the Philadelphia with 3 tsp of caster sugar until soft.

Pour the chocolate mixture into a silicon (or metapan in a larger slow cooker, or for a smaller slow cooker e.g. 3.5 litre, pour it into your slow cooker pot lined with baking paper and greased in case any mixture escapes.

Step 5

Dot the sugared Philadelphia on top and marble it with a knife.

Step 6

Put the lid on, and cook on high for approx. 1-2 hours until firm round the edges with a wobble left in the middle. Or cook until completely firm if you like your brownies without the gooey-ness.
