1 tablespoon butter
Preheat oven to 325°F. Generously grease a 13×9 baking pan with butter and set aside.
4 large eggs
1 ½ cups sugar
1 teaspoon vanilla extract
Whisk together eggs, sugar, and vanilla in a large bowl.
8 ounces semisweet chocolate, chopped into pieces or in chips
12 tablespoons butter (1 ½ sticks)
In a separate microwave safe bowl, heat chocolate and butter at half power until melted, about 3 minutes. Stir until smooth and whisk into bowl with creamed egg mixture.
1 cup buttermilk
½ teaspoon baking soda
Add buttermilk and baking soda and whisk until combined.
1 ½ cups unbleached all-purpose flour
¾ cup cocoa powder
¼ teaspoon salt

Pour batter into greased pan and bake at 325°F until center firms up and a toothpick inserted into the cake comes out clean, about 40 minutes.
Remove from oven and let cool completely on a wire rack, at least 1 hour.
2 cups brown sugar
1 cup heavy cream
In a small saucepan, whisk together brown sugar and heavy cream until sugar has completely dissolved.
Cover and cook over medium heat until just starting to steam to ensure that sugar has completely dissolved.
Uncover and cook without stirring until sauce reaches 238°F to 240°F on an instant read thermometer.

Let rest on the counter until reaches 110°F on an instant read thermometer, about 20 minutes.

Spread on top of cake using an offset spatula.
Serve with milk, whipped cream, or even a scoop of sea salt caramel ice cream.
