In a bowl, add butter and dark chocolate. Melt them over a double boiler or microwave at 30 seconds intervals, stirring in between, until smooth.
Add in the sugar, warm milk and mix them using a whisk until the sugar is dissolved.
Now fold in the dry ingredients- all purpose flour and cocoa powder using a spatula.
Roast and chop the pecans and fold them in the batter as well.
Transfer the batter into 4*4 inches square pan and bake it at 180 degrees celsius for 15-20 minutes.
For the chocolate sauce, in a saucepan set over medium heat, combine chopped dark chocolate, cocoa powder, water, and sugar. Bring the mixture to a boil, stirring until fully combined. Take it off the heat and add 1 tbsp butter and whisk the chocolate mixture until smooth.
