Preheat the oven to 160°C. Melt the chocolate and butter together in a bowl suspended over a saucepan of simmering water – the mixture should have a smooth, glossy consistency (take care not to overheat it).

Set aside to cool slightly. In a mixer, cream together the sugar and eggs, then add the cocoa powder, flour and baking powder. Add the chocolate mixture and beat until combined.

Pour the mixture into a greased 25 x 35 cm baking dish and bake for 50 minutes, or until just set but still slightly undercooked (the chocolate will set further when cooling).

To make the decoration: In a bowl suspended over a saucepan of simmering water, melt the chocolate, then whisk in the cream until smooth. Pipe a word of your choice over the brownie and decorate with chocolatedipped cherries.
