Step 1

Preheat the oven to 180ºC/gas

Step 2

Line a 20cm square baking tin (or the equivalent) with greaseproof paper. Melt the butter and dark chocolate in a bowl over a saucepan of simmering water (don’t let the bowl touch the water). Destone the cherries and roughly chop them along with the pecans. Stir into the melted chocolate, then take off the heat. In another bowl, add the sugar, then sift in the cocoa powder, flour and baking powder. Add to the melted chocolate mixture and stir till well combined. Beat the eggs and mix in. Roughly chop and stir through the milk or dark chocolate (if using). Transfer the mixture to the tin, then bake in the oven for 15 to 20 minutes. You want them a little gooey in the middle. Remove from the oven and cool in the tray, before cutting into squares.
