Ingredients
- 8 ounces unsweetened dark chocolate, roughly chopped
- 1/2 lb (two sticks) unsalted butter
- 2 cups sugar
- 6 large eggs
- 1 cup unsweetened cocoa powder
- 1/8 tsp sea salt
- 1 tsp vanilla
Preparation
Step 1
Preheat oven to 350 degrees F.
Add butter to a 10-inch cast iron pan and cook over medium heat for 5 minutes or so, until it turns nut brown in color. Foam and bubbles are part of the browning process, but watch carefully so that you don't burn the butter.
Begin to melt chocolate in a double boiler or a large metal bowl set over a saucepan of barely simmering water.
Pour the butter from the cast iron into the melting chocolate and set the cast iron aside. Stir together until mixture is smooth.
Remove bowl from heat and whisk in sugar.
Add eggs one at a time, whisking well after each addition.
Add vanilla
Sift cocoa powder into chocolate and whisk until just combined.
Pour batter into cast iron skillet.
Bake on the middle rack until a wooden pick inserted in center of cake comes out clean, 35-40 minutes.
Cool cake in pan on a rack for 10 minutes.
Invert cake onto a plate and reinvert onto rack to cool completely.
Dust cake with cocoa powder or powdered sugar before serving.
