Ingredients
For the Brownie Cake
- 240 ml (1 cup) unsalted butter, melted
- 360 ml (1 1/2 cups) granulated sugar
- 240 ml (1 cup) packed light brown sugar
- 4 large eggs
- 5 ml (1 tsp) vanilla extract
- 360 ml (1 1/2 cups) all-purpose flour
- 120 ml (1/2 cup) unsweetened cocoa powder
- 2.5 ml (1/2 tsp) baking powder
- 1.25 ml (1/4 tsp) salt
- 240 ml (1 cup) semisweet chocolate chips
For the Chocolate Fudge Sauce
- 120 ml (1/2 cup) heavy cream
- 120 ml (1/2 cup) unsweetened cocoa powder
- 60 ml (1/4 cup) granulated sugar
- 30 ml (2 tbsp) unsalted butter
- 5 ml (1 tsp) vanilla extract
Optional Substitutions
- For a gluten-free version, swap all-purpose flour with a 1:1 gluten-free flour blend.
- Replace heavy cream with coconut cream for a dairy-free alternative.
- Dark chocolate chips or chunks can be used instead of semisweet for a more intense flavor.
Step-by-Step Instructions
Preheat Oven
- Preheat your oven to 180°C (350°F). Grease and flour a 9×13-inch baking pan to prevent sticking.
Prepare Brownie Cake Batter
- In a large bowl, combine the melted butter, granulated sugar, and brown sugar. Mix well until fully incorporated.
- Add the eggs, one at a time, beating well after each addition to ensure a smooth batter.
- Stir in the vanilla extract.
- In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
- Gradually add the dry ingredients to the butter mixture, mixing just until combined. Overmixing can lead to a tougher texture.
- Fold in the chocolate chips to distribute them evenly.
- Pour the batter into the prepared baking pan, spreading it evenly for uniform baking.
Bake Brownie Cake
- Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. The cake should be firm but still fudgy.
- Allow the cake to cool completely in the pan before cutting. This helps it set and prevents crumbling.
Prepare Chocolate Fudge Sauce
- In a saucepan, combine the heavy cream, cocoa powder, sugar, and butter. Heat over medium heat, stirring constantly until the sugar dissolves and the mixture becomes smooth.
- Remove from heat and stir in the vanilla extract.
- Let the sauce cool slightly before drizzling to achieve the perfect consistency.
Serve
- Cut the cooled brownie cake into even slices.
- Drizzle the warm chocolate fudge sauce generously over each slice.
- Serve immediately and enjoy this rich, indulgent Chocolate Fudge Brownie Cake.

Healthier Alternatives

Serving Suggestions
- Top with fresh berries for a refreshing contrast.
- Add a scoop of vanilla ice cream for an extra indulgent dessert.
- Pair with a hot cup of coffee or cold milk to balance the richness.
Common Mistakes to Avoid
- Overbaking the cake, which can make it dry instead of fudgy. Check doneness at the 30-minute mark.
- Overmixing the batter, leading to a dense texture. Mix until just combined.
- Using hot fudge sauce immediately—letting it cool slightly ensures a thicker drizzle.
Storage Tips
- Refrigeration: Store covered in the fridge for up to 5 days. Reheat slices for 10 seconds in the microwave before serving.
- Freezing: Wrap individual slices tightly and freeze for up to 2 months. Thaw at room temperature before enjoying.

Frequently Asked Questions
Can I use milk chocolate chips instead of semisweet?
Yes, but the cake will be sweeter. Semisweet chocolate provides a balanced flavor, but milk chocolate is a suitable substitute if you prefer a milder sweetness.
How do I know when the cake is done baking?
Insert a toothpick into the center. If it comes out with a few moist crumbs but no wet batter, it's done. Overbaking can dry it out.
Can I make the cake in advance?
Absolutely! Bake the cake a day ahead and store it covered at room temperature. Prepare the fudge sauce just before serving for the best results.
What if my fudge sauce is too thick?
Simply reheat it gently and add a teaspoon of milk or cream to thin it slightly. Stir until smooth.
Can I use store-bought chocolate sauce instead?
While homemade fudge sauce enhances the flavor, store-bought chocolate syrup can work in a pinch. However, the texture and taste will differ slightly.
How do I prevent the cake from sticking to the pan?
Grease the pan thoroughly and dust it with flour or cocoa powder. Lining the pan with parchment paper is another foolproof method.
