Preheat your oven to 350°F. Thoroughly grease and flour a 9x13 inch baking pan. This crucial step ensures your Decadent Hot Fudge Cake Recipe releases perfectly from the pan after baking.

In a large mixing bowl, whisk together 2 cups all-purpose flour, 3/4 cup unsweetened cocoa powder, 1 3/4 cups granulated sugar, 1/2 cup light brown sugar, 1 1/2 tsp baking soda, and 1 tsp fine sea salt until well combined.

In a separate medium bowl, combine 2 large eggs, 1 cup buttermilk, 1/2 cup (1 stick) unsalted butter, melted, and 2 tsp pure vanilla extract. Whisk these ingredients together until they are fully blended.

Pour the wet ingredient mixture into the dry ingredients. Stir with a spatula until just combined, being careful not to overmix. Spread the resulting cake batter evenly into your prepared 9x13 inch baking pan.

In a medium saucepan, combine 6 oz unsweetened chocolate, 1 cup heavy cream, 1/2 cup granulated sugar, 1/4 cup (1/2 stick) unsalted butter, 1 tsp pure vanilla extract, and 1/4 tsp fine sea salt. Heat over medium-low, stirring constantly until the mixture is smooth and fully melted.

Carefully pour the hot fudge mixture evenly over the cake batter in the pan. Do not stir or mix. Bake for 40 minutes, or until a toothpick inserted into the cake (avoiding the fudge layer) comes out clean. This creates the perfect Decadent Hot Fudge Cake Recipe.

Allow the Decadent Hot Fudge Cake Recipe to cool in the pan for at least 15-20 minutes before serving. Just before serving, dust generously with 2 tbsp powdered sugar. Serve warm to enjoy the molten fudge core.
