Take a bowl and put egg and sugar in it, using a whisker whisk it well until the sugar dissolves.

Add milk, oil, vanilla essence and melted chocolate together and mix it well.

Then add flour, cocoa powder and baking powder and mix it well until the batter is smooth.

Place the batter in a cake mold.

Now set the temperature of the oven at 180 degree celsius and put the batter in it for 30 minutes.

After 30 minutes take out the brownie and unmold it when it gets cold.
