Pre-heat oven at 180c.
Fill a small saucepan about a quarter full and bring to a boil on medium heat, then sit a transparent bowl on top so it rests on the rim of the pan, not touching the water. Add chocolate and butter.
Reduce heat to low until butter and chocolate have melted, stirring occasionally to mix them.
Remove the bowl from the pan and let cool off a bit.
Add eggs one at a time, stir, then add cocoa powder and stir in.
Add vanilla essence, stir and fold in the flour into a smooth mixture, then add the milk chocolate drops.
Grease a baking pan with cooking spray/butter and pour the mixture in.
Bake at 180c for 25-30 minutes.
Take out from the oven and let cool off completely, then cut them into pieces.
Brownie ready to serve.
Cut into squares and enjoy!
