# What you'll need:
→ Chocolate Mixture
01 - 8 oz unsalted butter
02 - 6 oz semisweet chocolate, chopped
→ Batter
03 - 4 large eggs, at room temperature
04 - 2 cups granulated sugar
05 - 1/2 cup all-purpose flour
06 - 2 tbsp unsweetened cocoa powder
07 - 2 tsp vanilla extract
08 - 1/4 tsp kosher salt
→ For Serving (optional)
09 - Vanilla ice cream or lightly sweetened whipped cream
# How to make it:
01 - Preheat the oven to 325°F. Butter a 2-quart baking dish and set aside.
02 - In a heatproof bowl set over simmering water, melt the butter and semisweet chocolate together, stirring until smooth. Remove from heat and allow to cool slightly.
03 - Using a stand mixer fitted with the paddle attachment, beat the eggs and sugar on medium-high speed for 5 to 10 minutes until the mixture is thick, pale, and ribbons form when lifted.
04 - Reduce mixer speed to low. Add vanilla extract and salt, then pour in the cooled chocolate mixture, mixing just until combined.
05 - Sift together the flour and cocoa powder, then gently fold into the batter using a spatula until just incorporated.
06 - Pour the batter into the prepared baking dish. Place the dish inside a larger roasting pan and add hot water halfway up the sides of the baking dish to create a water bath. Bake for 1 hour until the top is set and crackly but the center remains soft and pudding-like.
07 - Remove from the water bath and allow to cool for at least 15 minutes. Serve warm, ideally accompanied by vanilla ice cream or whipped cream.
