Ingredients You’ll Need

Gather your chocolatey arsenal!

For the Cake:

• 2 cups (240g) All-purpose flour: The backbone of all good cakes.
• 2 cups (400g) Granulated sugar: Sweetness, duh.
• ¾ cup (75g) Unsweetened cocoa powder: The dark, rich chocolatey goodness.
• 2 teaspoons Baking soda: For lift, so your cake isn’t a brick.
• 1 teaspoon Baking powder: Extra lift insurance!
• 1 teaspoon Salt: Don’t skip it, it truly brings out the chocolate flavor!
• 2 large Eggs: Binders, fresh from the chicken or the carton, your call.
• 1 cup (240ml) Milk: Whole milk is best, adds richness.
• ½ cup (120ml) Vegetable oil: Keeps it ridiculously moist, no dry cake allowed.
• 2 teaspoons Vanilla extract: A little *oomph* for flavor depth.
• 1 cup (240ml) Boiling water: Sounds weird, works wonders for extra moistness and bloom.

For the Chocolate Ganache:

• 12 oz (340g) Good quality dark chocolate: **This is key!** Chips or finely chopped bar, 60-70% cacao is great for that intense flavor.
• 1 ½ cups (360ml) Heavy cream: The magic ingredient for silky ganache.
• 2 tablespoons Unsalted butter: Just a tiny bit for extra shine and richness. (Optional, but highly recommended!)

Step-by-Step Instructions

For the Cake:

1. **Prep Time!** Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans. Or, even better, line the bottoms with parchment paper circles. Don’t skip this, unless you like your cake glued to the pan.
2. **Dry Mix.** In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt. Make sure there are no lumps. You want everything well incorporated.
3. **Wet Mix.** In another medium bowl, whisk the eggs, milk, vegetable oil, and vanilla extract until they’re nicely combined.
4. **Combine.** Slowly add the wet ingredients to the dry ingredients, mixing on low speed with an electric mixer (or by hand) until just combined. **Do not overmix!** You want a tender cake, not a tough one.
5. **Boiling Water Magic.** Carefully, and slowly, stir in the boiling water until the batter is smooth. It will be thin – that’s completely normal! This is the secret to its amazing moistness.
6. **Bake It!** Divide the batter evenly between your two prepared pans. Bake for 30-35 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean.
7. **Cool Down.** Let the cakes cool in their pans for about 10-15 minutes, then carefully invert them onto a wire rack to cool completely. **Patience is a virtue here.** Seriously, don’t rush this, or your cake will crumble and make you sad.

For the Chocolate Ganache:

1. **Chop Chocolate.** If you’re using a chocolate bar, chop it into small, uniform pieces. Place all the chopped chocolate (or chips) into a heatproof bowl.
2. **Heat Cream.** In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer around the edges. **Do not boil it vigorously!**
3. **Pour & Wait.** Immediately pour the hot cream over the chocolate in the bowl. Let it sit for 5 minutes without stirring. This allows the hot cream to melt the chocolate evenly.
4. **Stir & Shine.** After 5 minutes, gently whisk the mixture from the center outwards until it’s completely smooth and wonderfully glossy. Stir in the butter (if using) until it’s fully melted and incorporated.
5. **Cool Ganache.** Let the ganache cool at room temperature for about 30-60 minutes, stirring occasionally, until it thickens to a luscious, spreadable, but still pourable consistency. It should be like thick syrup, not liquid.

Assembly Time!

1. **Level Up.** Once your cake layers are completely cool, level them with a serrated knife if they have a dome. This makes for a neater stack.
2. **Stack & Spread.** Place one cake layer on your serving plate or stand. Spread a generous layer of your beautiful, cooled ganache over the top of the first layer.
3. **Top It Off.** Carefully place the second cake layer on top. Pour the remaining ganache over the top, letting it drip artfully down the sides. Use an offset spatula or the back of a spoon to smooth it out if you want a cleaner look.
4. **Chill Out.** Pop it in the fridge for 15-30 minutes to set the ganache a bit, making it easier to slice cleanly.
5. **Devour!** Slice into your masterpiece and enjoy! You’ve earned this.

Common Mistakes to Avoid

• **Overmixing the batter:** This is a cardinal sin! Overmixing develops the gluten too much, giving you a tough, chewy cake instead of a tender one. Mix just until combined.
• **Not greasing/flouring pans properly:** Hello, stuck cake! A baking tragedy that’s easily avoided. Use plenty of butter/shortening and flour, or parchment paper.
• **Cutting into a warm cake:** It will crumble, tear, and generally make you sad. Seriously, **let the cakes cool completely** on a wire rack before frosting or leveling.
• **Overheating the cream for ganache:** Scorched cream equals bitter, gross ganache. Just a gentle simmer, then remove it from the heat.
• **Not using good quality chocolate for ganache:** This is where you taste the difference. Cheap chocolate will give you a subpar ganache. Invest in a decent bar, it’s worth it!

Alternatives & Substitutions

• **Dairy-free?** For the cake, use plant-based milk (almond, soy, oat) and your preferred vegetable oil. For the ganache, use full-fat coconut cream (the thick stuff from a can, chilled overnight, scoop out the solid part) instead of heavy cream, and ensure your dark chocolate is dairy-free. It’ll still be super rich!
• **Different chocolate?** For ganache, semi-sweet chocolate works great too for a slightly sweeter finish. Milk chocolate might be too sweet and too thin, IMO, so stick to dark or semi-sweet for best results.
• **Spice it up!** Add a pinch of instant espresso powder (about 1-2 teaspoons) to the cake batter to really enhance and deepen the chocolate flavor without making it taste like coffee. Trust me on this one, it’s a game-changer.
• **No boiling water?** Warm strong coffee (same quantity) works too, for an even deeper, more complex chocolate flavor profile!

FAQ (Frequently Asked Questions)

Got questions? I’ve got answers!

1. **”My ganache is too thin! What did I do wrong?”** Probably didn’t let it cool long enough. Pop it in the fridge for 10-15 minute intervals, stirring in between, until it thickens. FYI, sometimes it’s also about the chocolate’s cocoa solids percentage; lower percentages yield thinner ganache.
2. **”Can I make this cake ahead of time?”** Absolutely! The cake layers can be baked a day or two in advance, wrapped tightly in plastic wrap, and kept at room temperature. The ganache can be made a day ahead and gently reheated (microwave in 15-second bursts or over a double boiler) to a pourable consistency.
3. **”Do I really need boiling water?”** Yes! It makes the cake incredibly moist and helps ‘bloom’ the cocoa powder, enhancing its flavor. Don’t skip this magical step!
4. **”What kind of cocoa powder should I use?”** Natural unsweetened cocoa powder (like Hershey’s or Ghirardelli) is perfect for this recipe as it reacts with the baking soda. Dutch-processed cocoa powder gives a darker color and milder flavor, but stick with natural here.
5. **”My cake stuck to the pan, HELP!”** Oh no! Next time, really grease and flour those pans thoroughly, or use parchment paper rounds on the bottom. For now, try to piece it back together with the ganache – it hides a multitude of sins!
6. **”Can I make cupcakes with this recipe?”** Yep! Divide the batter into cupcake liners and bake for about 18-22 minutes, or until a toothpick comes out clean. Adjust your expectations for ganache coverage, though – it’s more of a drizzle than a thick coating for cupcakes.
