Preheat oven to 350 degrees F

Grease and flour an 8" round cake pan

In a heavy saucepan melt the chocolate and butter together over low heat. Stir frequently to prevent the chocolate from burning at the bottom. Set aside and cool

Using the paddle attachment of your mixer, mix the eggs and sugar on high speed for 5-7 minutes or until the mixture becomes pale and thick

Slowly add the flour, salt, and vanilla. Keep mixing. Remember to scrape the bottom of the bowl with a spatula

Finally add the cooled chocolate mixture slowly.

Pour batter into the prepared cake pan

Bake for 38-45 minutes or until there's a slight wobble in the middle of the cake. Mine took 40 minutes

Remove from oven and cool in pan for 10 minutes. Cake will deflate slightly

Turn the cake into a cake plate. If desired, sprinkle some dusting sugar on top and serve

Enjoy!
