Ingredients You’ll Need

The magic in this Spider Cake Recipe really starts with the quality of your ingredients. The cocoa powder, buttermilk, and buttercream components all work together to bring out rich chocolate flavor and a tender crumb. Don’t worry if you can’t find Dutch-processed cocoa – natural cocoa works fine too, just be aware it might give a slightly different flavor.

• All-purpose flour: Spoon and level it for accuracy or weigh it for best results.
• Granulated sugar: Regular white sugar – the backbone of sweetness.
• Dark/Dutch-processed cocoa powder: Adds that deep chocolate richness.
• Baking powder & baking soda: Both work together to give your cake lift and tenderness.
• Fine salt: Enhances the chocolate flavor.
• Hot water: Helps dissolve cocoa powder and intensifies chocolate flavor.
• Buttermilk: Keeps the cake moist and tender with a slight tang.
• Vegetable or canola oil: To keep the cake ultra moist without making it dense.
• Large egg: Helps bind and give structure to the cake.
• Vanilla extract or vanilla bean paste: Adds warmth and complexity.
• Unsalted butter: For the buttercream, softened to room temp for smooth creaming.
• Powdered sugar: Sweet smoothness for your frosting.
• Heavy whipping cream: Adds creaminess and lightness to the buttercream.
• Dark chocolate chips: Melted to enrich the frosting with more chocolate goodness.
• Dark baking cocoa (sifted): Intensifies the buttercream’s dark color and flavor.
• Black gel food coloring: Gives that perfect spider black shade without watering down the frosting.
• Black bubble tea straws: Your spider legs—flexible and safe for decorating!

Variations

One of my favorite things about this Spider Cake Recipe is how flexible it can be. Whether you want to play with flavors or adjust for dietary needs, it’s super easy to make it your own. I often swap cocoa types or try different extracts in the frosting, depending on my mood.

• Gluten-Free Option: You can substitute all-purpose flour with a reliable gluten-free baking mix that measures cup-for-cup; just watch the bake time as it can vary.
• Flavor Twists: Try adding a hint of espresso powder to the batter for deeper chocolate flavor or a pinch of cinnamon for warmth.
• Dairy-Free Version: Use coconut oil instead of butter and a dairy-free milk mixed with vinegar instead of buttermilk for a tasty alternative.
• Colorful Frosting: If you want a less spooky spider, swap the black gel food coloring for deep purple or green for a Halloween twist kids adore.

How to Make Spider Cake Recipe

Step 1: Prepare the Cake Pans and Batter

Start by preheating your oven to 350°F (175°C) and greasing two 6-inch domed cake pans well with non-stick spray or a homemade cake release. If you have heating cores, pop those in the center of each pan—they help the cake bake evenly and avoid undercooked middles. I place my pans on a baking sheet to make moving them in and out easier, which is a small but helpful trick.

Whisk together all your dry ingredients—flour, sugar, cocoa powder, baking powder, baking soda, and salt. Separately, mix the wet ingredients—hot water, buttermilk, oil, egg, and vanilla—until they’re smooth. Then gently fold the wet into the dry just until combined. You’ll want to avoid overmixing; it’s tempting to keep stirring, but that can make the cake tough.

Step 2: Bake the Layers

Divide the batter evenly between your pans—ideally filling no more than two-thirds full to give the layers room to rise without spilling over. If you’re a perfectionist like me, a kitchen scale is your best friend here! Bake for about 35-40 minutes or until a toothpick inserted comes out with a few moist crumbs. Since ovens vary, start checking at 35 minutes to avoid overbaking.

Once baked, cool them in the pans for 10 minutes, then carefully flip onto wire racks to cool completely before trimming and assembling.

Step 3: Make the Chocolate Buttercream

Beat unsalted butter on medium speed until creamy, about 30 seconds. Add vanilla and salt, mixing on low to combine. Gradually add powdered sugar, midway adding heavy cream to keep it smooth and spreadable.

Set aside about a quarter cup of this white buttercream in a small bag for piping the spider’s eyes later. Melt the dark chocolate chips and let them cool before folding them in with sifted dark cocoa powder and a squirt of black gel food coloring. Mix on low until your frosting is a rich, smooth black—scrape the sides to get everything evenly colored.

Step 4: Assemble Your Spider Cake

Before stacking, fold each bubble tea straw about halfway down and place them in a heavy book to hold their bend for 20-30 minutes—this gives your spider legs that perfect creepy curve. Stack your cakes on a greased cake board, starting with the layer that has a trimmed dome for easier stacking. Dab a bit of chocolate buttercream under it to help it stick.

Spread an even layer of frosting on top, then stack the next cake layer. Pop the cake in the freezer for 10 minutes to firm it up—that step really helps when applying the final smooth coat.

Cover the entire cake with a generous layer of black buttercream and smooth it with an offset spatula or acetate sheet. Next, pipe two white and black frosting eyes on one side. Use a large grass piping tip to create the fuzzy black spider body effect by covering the cake with piped buttercream.

Finally, press four bubble tea straw legs on each side of the cake, securing their bases with tiny strips of clear tape on the cake board. And voilà – your spider cake is ready to amaze!

How to Serve Spider Cake Recipe

Garnishes

I love keeping the garnishes simple to let the spider design shine. Just piping those cute white eyes with black centers adds personality. Sometimes I sprinkle on a pinch of edible glitter on the legs to give them a slight shimmer, which kids and adults both enjoy.

Side Dishes

This cake is decadent enough to stand on its own, but if you want to balance it out, I suggest fresh berries or a light vanilla bean ice cream on the side. A cup of strong coffee or rich hot chocolate also pairs beautifully—it’s a perfect combo for cozy gatherings.

Creative Ways to Present

For Halloween parties, placing the spider cake on a silver platter over some decorative faux spider webs really amps up the effect. I’ve also tried mini spider cupcakes matching the design as fun accompanying treats. If you want a spooky flair, add plastic spiders around the display (just remind guests to eat only the cake!).

Make Ahead and Storage

Storing Leftovers

After slicing into this spider cake, you’ll want to save the leftovers for later. I store mine covered in the refrigerator to keep the buttercream from drying out. Wrapped tightly, the cake keeps well for up to a week, making it a convenient treat you can enjoy over several days.

Freezing

I love freezing leftover cake layers before assembly—it saves time during busy weeks! Wrapped tightly in plastic wrap and foil, the layers freeze well for up to a month. The buttercream also freezes beautifully; just thaw in the fridge and stir before using.

Reheating

Since this cake is best served chilled, I typically take it out of the fridge about 20 minutes before serving to bring it to room temperature. If you need to refresh leftover slices, a quick 10-second zap in the microwave softens the buttercream and makes the chocolate flavor pop.
