Ingredients

• 1 cup (2 sticks/226 g) unsalted butter, cut into pieces
• 8 oz (225 g) dark or semisweet chocolate, chopped
• 1 3/4 cups (350 g) granulated sugar
• 1/2 cup (100 g) light brown sugar, packed
• 4 large eggs, room temperature
• 2 tsp vanilla extract
• 1 cup (120 g) unsweetened cocoa powder, Dutch-process or natural

• Optional ganache: 1/2 cup (120 ml) heavy cream + 4 oz (115 g) chopped chocolate

Instructions

1. Prep the pan and oven: Heat oven to 350°F (175°C). Grease a 9-inch springform pan or deep cake pan, then line the base with parchment.Lightly dust with cocoa to prevent sticking.
2. Melt butter and chocolate: Place butter and chopped chocolate in a heatproof bowl. Microwave in 20–30 second bursts, stirring between each, until smooth. Cool for 5 minutes.
3. Whisk sugars and eggs: In a large bowl, whisk granulated sugar, brown sugar, and eggs for about 1 minute until thickened and slightly lightened.Whisk in vanilla.
4. Combine with chocolate: Slowly pour the melted chocolate mixture into the egg mixture while whisking. Stir until glossy and fully combined.
5. Add dry ingredients: Sift in cocoa powder, flour, salt, and baking powder. Fold gently with a spatula just until no dry streaks remain.Do not overmix.
6. Fold in chips: Stir in chocolate chips or chunks. The batter will be thick and shiny.
7. Bake: Pour into the prepared pan and smooth the top. Bake 35–45 minutes, until the edges are set and a toothpick inserted 2 inches from the edge comes out with moist crumbs.The center should still look slightly soft.
8. Cool: Set the pan on a rack and cool for at least 45–60 minutes. For the cleanest slices, cool to room temperature or chill 30 minutes before unmolding.
9. Optional ganache: Warm cream to a gentle simmer, pour over chopped chocolate, let sit 2 minutes, then stir until smooth. Spread over the cooled cake and let set 10–15 minutes.
10. Serve: Slice with a warm knife for neat edges.Great on its own, or add whipped cream, berries, or a scoop of vanilla ice cream.

Storage Instructions

• Room temperature: Keep covered at cool room temp for up to 3 days. The texture stays fudgy.
• Refrigerator: Store airtight for up to 5 days. Let slices sit out 20 minutes before serving for the best texture.
• Freezer: Wrap slices tightly and freeze up to 2 months.Thaw in the fridge overnight or at room temp for about 1 hour.
• Ganache-topped cakes: Best stored chilled to keep the glaze firm.

Health Benefits

• Cocoa antioxidants: Dark chocolate and cocoa provide flavanols, which support heart health when enjoyed in moderation.
• Mood boost: Chocolate contains compounds that can support feel-good neurotransmitters.
• Portion-friendly: Dense sweets satisfy with smaller slices, helping you enjoy dessert without overdoing it.
• Customizable sugars: You can reduce overall sugar slightly or use darker chocolate for a less sweet version.

What Not to Do

• Don’t overbake: If you wait for a clean toothpick in the center, the cake will be dry. Aim for moist crumbs and a just-set edge.
• Don’t skip parchment: This cake is sticky. Lining the pan prevents heartbreak when unmolding.
• Don’t overmix the batter: Too much stirring after adding flour can make the cake tough.
• Don’t cut while hot: It needs time to set.Slicing too soon leads to crumbling and lost shine.
• Don’t use low-quality chocolate: The flavor depends on it. Choose chocolate you enjoy eating on its own.

Variations You Can Try

• Salted caramel swirl: Dollop thick caramel over the batter and swirl lightly. Finish with flaky sea salt.
• Espresso boost: Add 1–2 tsp instant espresso powder to deepen the chocolate flavor without making it taste like coffee.
• Nut lover’s version: Fold in 3/4 cup toasted walnuts, pecans, or hazelnuts for crunch.
• Gluten-free swap: Use a cup-for-cup gluten-free flour blend.Let the batter rest 10 minutes before baking.
• Mint chocolate: Add 1/2 tsp peppermint extract and use a mix of dark and mint chips.
• Raspberry layer: Spread a thin layer of raspberry jam over the baked, cooled cake, then add ganache.

FAQ

Can I use cocoa powder only and skip the melted chocolate?

Yes, but the result won’t be as rich or fudgy. For a cocoa-only version, increase butter by 2 tablespoons and add an extra 1/4 cup sugar. Expect a slightly drier crumb.

What chocolate percentage works best?

Aim for 55–70% cocoa dark or semisweet chocolate.

Lower percentages make it sweeter; higher than 70% can taste a bit intense and may dry the batter unless you add a tablespoon of extra butter.

How do I get that shiny crackle top?

Whisk the eggs and sugars well until slightly thick, and ensure the melted chocolate is warm (not hot) when combined. That emulsion helps create the glossy crust.

Can I bake this in a different pan?

Yes. A 9×9-inch square pan works well; start checking at 28–32 minutes.

For a 9×13-inch pan, the cake will be thinner; bake 22–28 minutes. Always watch the edges and test for moist crumbs.

Is it too sweet with chocolate chips and ganache?

Not if you balance with darker chocolate. Use 70% chocolate for melting and semi-sweet chips.

You can also skip the ganache or choose bittersweet chocolate for it.

How do I know when it’s done?

Look for set, slightly puffed edges and a center that’s just barely jiggly. A toothpick around the edge should have moist crumbs; the center should not be liquid.

Can I make it dairy-free?

Use a dairy-free butter alternative that’s solid at room temperature and choose dairy-free chocolate. Skip ganache or make it with canned coconut milk.
