What Ingredients You Will Need
This cake uses straightforward, reliable ingredients to create bold chocolate flavor and a truly creepy look. Most items are pantry staples, and you can tweak a few for dietary needs or personal taste.
- For the cake batter:
- 1 3/4 cups (220g) all-purpose flour
- 3/4 cup (65g) unsweetened dark cocoa powder (for that deep, haunted look)
- 2 cups (400g) granulated sugar
- 1 1/2 tsp baking powder
- 1 1/2 tsp baking soda
- 1/2 tsp salt
- 2 large eggs, room temperature
- 1 cup (240ml) whole milk (or almond milk for dairy-free)
- 1/2 cup (120ml) vegetable oil (I prefer canola—it keeps the crumb moist)
- 2 tsp pure vanilla extract
- 1 cup (240ml) boiling water (makes the cake extra tender)
- For the chocolate ganache:
- 1 1/4 cups (210g) semi-sweet chocolate chips (I love Ghirardelli for meltability)
- 1 cup (240ml) heavy cream
- 2 tbsp unsalted butter (optional, for shine)
- For decorating:
- Candy eyes (for a playful, creepy effect)
- Edible spiders or gummy worms
- Red raspberry sauce (for blood drips, totally optional)
- Ghost-shaped marshmallows or meringues
- Halloween sprinkles
If you want to go gluten-free, substitute the all-purpose flour with a 1:1 gluten-free blend (Bob’s Red Mill is solid). For richer flavor, swap some of the milk for buttermilk. You can use bittersweet chocolate for the ganache if you want a more grown-up taste. When it comes to decorations, honestly, anything goes—just raid your pantry or the Halloween aisle at the grocery store.
Ingredient tip: Use high-quality cocoa and chocolate chips for the best texture and flavor. I learned the hard way that bargain chocolate sometimes doesn’t melt evenly. If you’re feeling extra creative, homemade marzipan “fingers” or fondant bones are super fun to add.

Equipment Needed
- Two 9-inch (23cm) round cake pans (nonstick or greased and lined)
- Large mixing bowl
- Medium saucepan (for heating cream)
- Whisk and rubber spatula
- Electric mixer (hand or stand, either works)
- Wire cooling rack
- Offset spatula or butter knife (for spreading ganache)
- Microwave-safe bowl (to melt chocolate if you prefer)
- Cake turntable (optional, but makes decorating easier)
I usually use basic nonstick pans—just line with parchment so nothing sticks. If you don’t have a turntable, just use a big plate (I’ve done it plenty of times). For the ganache, you can melt chocolate in the microwave, but a saucepan gives more control. Keep your mixer clean and dry—moisture messes up the batter texture. If you’re on a budget, dollar store spatulas and cake pans do the job just fine, but invest in a sturdy whisk if you bake often.
After a few Halloween seasons, I’ve learned that keeping your decorating tools handy saves a ton of time. If you’re using candy eyes or sprinkles, set them out before you start pouring ganache—they stick better when the ganache is still a little warm.
Preparation Method
- Prep your pans: Preheat oven to 350°F (175°C). Grease two 9-inch (23cm) round pans and line with parchment. This helps avoid sticking (trust me, I’ve lost a few cakes to bad pans before).
- Mix dry ingredients: In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt. It should look uniform and dark—if you see lumps, break them up.
- Mix wet ingredients: In another bowl, whisk eggs, milk, oil, and vanilla until smooth. It’ll look pale and creamy.
- Combine wet and dry: Pour wet mixture into dry, whisk gently until mostly combined (a few streaks are okay).
- Add boiling water: Slowly pour in boiling water while whisking. The batter will thin out and look glossy—don’t worry, that’s right. Batter should be pourable but not watery.
- Bake: Divide batter evenly between pans. Bake for 25–30 minutes, until a toothpick inserted in the center comes out clean. Cakes will rise and pull slightly from the sides.
- Cool: Let cakes cool in pans for 10 minutes. Then turn onto racks and cool completely (about 30 minutes). Warm cakes will melt ganache, so don’t rush this step.
- Make ganache: Heat heavy cream in a saucepan over medium heat until just simmering—don’t boil. Pour over chocolate chips in a bowl, let sit 2 minutes, then whisk until smooth. Stir in butter for extra shine.
- Assemble cake: Place one cake layer on your plate. Spread a generous layer of ganache (about 1/3 of it) on top. Place the second layer over, then pour remaining ganache over the top, letting it drip down the sides for a creepy effect.
- Decorate: While ganache is still gooey, add candy eyes, gummy worms, and sprinkles. Drizzle raspberry sauce for “blood” if you like. Let cake set for 30 minutes before slicing.
Preparation notes: If your ganache is too thick, microwave it in 10-second bursts. If your cake layers dome too much, trim them flat with a serrated knife. Don’t stress if ganache drips unevenly—imperfection looks spookier! If you’re really short on time, you can make cake layers a day ahead and wrap tightly in plastic.
Sensory cues: The cake should smell rich and chocolaty as it bakes, and the ganache should be glossy and smooth. Decorating is the fun part—let your imagination run wild!
Cooking Tips & Techniques
I’ve baked this Halloween chocolate ganache cake so many times that I’ve hit a bunch of snags—and found solutions! Here are my best tips for perfect results:
- Room temperature ingredients: Eggs and milk mix more smoothly when not cold. If you forget, just set them in warm water for 5–10 minutes.
- Don’t overmix: Once you add flour, mix gently. Overmixing makes the cake tough—I learned that the hard way (my first one was basically chocolate bread).
- Ganache consistency: If yours is too runny, let it cool for a few minutes. If it’s too thick, add a splash more cream and whisk.
- Layering: If your cakes stick, run a knife around the edge before turning out. For perfect slices, chill the cake for 30 minutes before cutting.
- Decorating: Add decorations while ganache is slightly warm so candy eyes and sprinkles stick. If everything slides off, let ganache set 10 minutes, then try again.
Common mistakes: Forgetting parchment (cake sticks), pouring ganache on hot cake (melts into crumbs), or using cheap chocolate (grainy ganache). I’ve had ganache seize up from overcooking—so watch it and don’t boil! If you want multitasking, prep decorations while cake bakes.
For consistency, weigh your flour and cocoa for best results. If you want extra richness, use a mix of bittersweet and semi-sweet chocolate. You can also make mini cakes or cupcakes using the same batter and ganache—just adjust baking times (about 18 minutes for cupcakes).
Variations & Adaptations
This Halloween chocolate ganache cake is super flexible. Here are my favorite ways to switch things up:
- Gluten-free: Use a 1:1 gluten-free flour blend. I’ve tried Bob’s Red Mill—works like a charm.
- Vegan: Swap eggs for flax eggs (2 tbsp flaxseed meal + 6 tbsp water), use almond milk, and coconut cream for ganache. Dairy-free chocolate chips work great.
- Flavor twist: Add 2 tsp instant espresso powder to the batter for mocha vibes, or a pinch of cinnamon for warmth.
- Seasonal touches: Decorate with candied orange peel, dried cranberries, or even pumpkin-shaped candies.
- Cooking methods: This recipe works as cupcakes (bake 18–20 minutes) or as a sheet cake (bake 28–32 minutes).
- Allergen swaps: Use sunflower butter instead of dairy for the ganache if there’s a nut allergy. For soy allergies, double-check chocolate ingredients.
My personal favorite adaptation was adding raspberry jam between layers for a “bloody” surprise. It was a hit! If you want to get wild, make a three-layer version and use neon green frosting for a “slime” effect.
Honestly, get creative—Halloween is all about fun! If you try a new twist, let me know in the comments.
Serving & Storage Suggestions
For maximum drama, serve this Halloween chocolate ganache cake at room temperature on a black or orange platter. The ganache is glossy and stays creamy—don’t refrigerate before serving unless you need to set decorations firmly. Pair with cold milk, hot cocoa, or a pumpkin spice latte for extra seasonal flair.
If you’re going all-out, surround the cake with candy corn and fake spiders for a haunted centerpiece. For parties, pre-slice and add a candy eye to each piece—it looks hilarious and spooky.
Leftovers keep well. Store covered at room temperature for up to 2 days, or refrigerate up to 5 days (the ganache may firm up, but you can microwave slices for 10 seconds to soften). Freeze un-decorated cake layers for up to a month—just thaw overnight and add ganache and decorations before serving.
Over time, the chocolate flavor deepens, so it’s still delicious the next day. If storing decorated cake, use parchment between slices to avoid smudging. I once kept a slice for three days—still tasted amazing!
Nutritional Information & Benefits
Each slice (about 1/12 of the cake) has roughly 340 calories, 22g fat, 40g carbs, and 5g protein. Most of the fat is from chocolate and cream, but you can lighten it up with low-fat milk or coconut cream.
The cake has iron and antioxidants from cocoa. Using dark chocolate chips boosts flavonoid content, which is good news for chocolate lovers. For gluten-free or vegan variations, nutrition changes a bit—plant-based milks lower saturated fat.
Potential allergens: Wheat, eggs, dairy, and soy (in chocolate chips). Always check labels for cross-contamination if you’re serving a crowd.
