Brownies from Landmark Confections dark chocolate and Hershey's cocoa

Because I'm an idiot I had to plan this ahead in order not to mess up. this is how I did it:
First I watched a few YouTube videos how to make Brownies, I think I picked the 3rd out of 6 or something
(Original recipe: https://youtu.be/Z1OLG7F3HD4).
Once I picked a video I wrote down I watched it a few more times to break it down. I came to conclusion that this recipe has 3 'small separate recipes'/instruction parts that merge into the batter that later we pour into an oild pan - cool!
Once we established the orders of the mission we prepare all the ingredients and their portions
upfront:

Dark chocolate 200 grams
Butter 1/2 cup
Sugar 1 cup
Brown sugar 1/2 cup
Salt 1/4 tsp
Eggs 3
Vanilla 1 tsp
Baking powder 1/2 a tsp
Flour 1/2 a cup
Cocoa powder 1/4 cup.

You got 3 main bowls - The 1st bowl is the melted chocolate with the butter.
The second bowl is the Sugar Brown sugar Eggs Salt Vanilla Baking powder.
Third bowl just sifting flour with Cocoa.
Mix bowl 2 with 1. Add 3rd bowl and pour into an oild pan.
350° for 30 minutes in a pre heated oven

Good luck 👍🏼
