# How to Make It:
01 - Preheat the oven to 325°F. Butter a 2-quart baking dish and set aside.
02 - Melt the butter and semisweet chocolate together in a heatproof bowl set over simmering water, stirring until smooth. Remove from heat and cool slightly.
03 - Using a stand mixer with paddle attachment, beat eggs and sugar on medium-high speed for 5 to 10 minutes until mixture is thick, pale, and ribbons form.
04 - Reduce mixer speed to low. Add vanilla extract and kosher salt. Pour in cooled chocolate mixture and mix until just combined.
05 - Sift together the flour and cocoa powder. Gently fold into the batter using a spatula until just incorporated.
06 - Pour batter into prepared baking dish. Place dish in a larger roasting pan and add hot water halfway up the sides to create a water bath. Bake for 1 hour until the top is set and crackly but center remains soft.
07 - Remove baking dish from water bath and cool for at least 15 minutes. Serve warm, optionally with vanilla ice cream or whipped cream.
