Heat oven to 180C/160C fan/gas 4
and line a 20cm square brownie tin with
baking parchment. Beat the butter and
sugar together with an electric whisk,
then add the eggs one by one. Sift in the
flour, cocoa powder and baking powder,
and add the milk. Mix everything
together, then stir in the chocolate chips.
Spoon into the tin and level the top.
Bake for 30 mins, or until the top is set,
then cool completely. To make the
topping, melt the milk chocolate, cool
a little, then mix it with the soft cheese.
Spread over the cooled brownies and cut
into small squares – these are very rich.
