Notes
*This recipe was written using an average of the dip and sweep method for measuring flour and the spoon and level method. If you are using a scale, you will need to add 3/4 oz or 22 gto the measurement for each cup of flour.
Make sure that you have dutch process cocoa powder and not natural process!
Beat the eggs, sugar, and vanilla for a full 10 minutes.
Be careful to not over mix the batter.
Once the batter is made, work quickly! If the batter sits too long, you won't get the shiny crust on your cookies.
To ensure each cookie is the same size, use a cookie scoop!
The less you bake the cookies, the more fudge-y they will be.
