Melt butter and the chopped chocolate in a medium sized saucepan, stirring constantly for about 5 minutes. Pour in a large sized bowl and allow to slightly cool for 10 minutes.
Preheat oven to 180. Grease a round baking tray and line it with a butterpaper. Whisk the granulated and brown sugars into the cooled butter and chocolate mix.
Add eggs one at a time, making sure to mix them well. Gently fold in the dry ingredients now. It's always better to sift them once or twice. Once combined, fold in the chocolate chips.
Bake this for about 30-35 minutes or till the Cake begins to pull away from the edges of the pan. Allow it to cool completely. Slice and serve.
