Another Option. Both methods are good and I use them interchangeably.
Melt butter and sugar together over medium heat until the butter has melted and the mixture is smooth. Add the chocolate and stir until chocolate melts. Continuing stirring until the mixture is smooth.
Add one egg at a time and mix until each is well incorporated before adding the next egg. Add vanilla (and espresso if using).

slightly soft. Place immediately in the freezer. When cold, remove and cut into bars. Wrap each bar in plastic wrap and store in the freezer.
