To prepare the brownie, preheat oven at 180-degree centigrade. Grease a 9-inch square baking dish ( buy it here ) with a little butter.
Sift flour, baking powder, cocoa powder together in a bowl. Add coffee powder, combine and set aside.
In another bowl cream together butter and sugar using electric hand blender at medium speed. Once the mixture turns fluffy and creamy in texture add one egg at a time and whisk for 2 - 3 minutes.
At last add chocolate essence and whisk the liquid mixture for few seconds.
Now combine liquid ingredients with the sifted flour mixture. Make sure no lumps or streaks remain in the batter.
Pour the batter in the greased baking dish.
Bake in the pre-heated oven for 20 - 25 minutes. Once baked transfer to a wire rack to cool down for sometime.
Cut the Cocoa Brownie into squares. Serve Cocos Brownie warm with vanilla ice cream.
