A rich, fudgy chocolate cake that’s denser than classic cake but more structured than brownies — the perfect marriage of two chocolate favorites.
1 cup unsalted butter
8 oz dark or semi-sweet chocolate, chopped
1½ cups granulated sugar
½ cup brown sugar
4 large eggs
2 tsp vanilla extract
¾ cup all-purpose flour
½ cup cocoa powder
½ tsp salt
1 tsp instant espresso powder (optional)
½ cup chocolate chips (optional)
Melt butter and chocolate until smooth. Let cool slightly.
In a bowl, whisk sugars, eggs, and vanilla. Stir in melted chocolate.
Sift in flour, cocoa, salt, and espresso powder. Mix until just combined.
Fold in chocolate chips if using.
Pour into greased 9-inch pan. Bake at 325°F for 35–42 minutes.
Cool before slicing. Serve plain or with toppings.
Store at room temp for 3 days or freeze for longer. Top with ganache or ice cream for extra indulgence.
