Set the bowl over a saucepan filled with 1 inch of simmering water.

Stir the mixture with rubber spatula until chocolate has melted.

Add 1/2 cup sugar to the chocolate and stir for about 2 minutes until glossy.

Remove bowl from heat and set aside to cool.

In a medium size bowl stir together the flour, baking soda, and salt.

In a small bowl, combine buttermilk and vanilla.

In a large mixing bowl, using an electric mixer, beat the eggs and yolks on medium-low speed about 10 seconds until combine.

Add remaining 1 1/4 cups of sugar, and increase speed to high. Beat 2 to 3 minutes, until fluffy and lightened in color.

Add in the cooled chocolate mixture and mix about one minute on medium speed until thoroughly incorporated. Scrape down sides of bowl with rubber spatula as needed.
