# What You'll Need:
→ Chocolate Mixture
01 - 8 oz unsalted butter
02 - 6 oz semisweet chocolate, chopped
→ Batter
03 - 4 large eggs, room temperature
04 - 2 cups granulated sugar
05 - 1/2 cup all-purpose flour
06 - 2 tablespoons unsweetened cocoa powder
07 - 2 teaspoons vanilla extract
08 - 1/4 teaspoon kosher salt
→ For Serving (optional)
09 - Vanilla ice cream or lightly sweetened whipped cream
# Directions:
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 with semisweet chocolate, stirring until smooth. Remove from heat and allow to cool slightly.
03 - Using a stand mixer fitted with the paddle attachment, beat eggs and sugar on medium-high speed for 5 to 10 minutes until thick, pale, and ribbon-like.
04 - Reduce mixer speed to low. Add vanilla extract and salt, then slowly add the cooled chocolate mixture, mixing just until combined.
05 - Sift together all-purpose flour and cocoa powder. Fold gently into the batter with a spatula until just incorporated.
06 - Pour batter into the prepared baking dish. Place this dish inside a larger roasting pan. Fill the roasting pan with hot tap water up to halfway up the smaller dish’s sides to create a water bath. Bake for 1 hour until the top is set and crackly but the center remains soft.
07 - Remove from the water bath and allow to cool for at least 15 minutes. Serve warm, optionally accompanied by vanilla ice cream or whipped cream.
