Spooky Halloween Spider Web Cupcakes

Category: Spooky Halloween Treats & Festive Party Food

Whip up tender chocolate cupcakes using mashed banana, buttermilk, and rich dark cocoa. Bake them until they're light and spongy, then set aside to cool completely. For the iconic spider web pattern, carefully drizzle dark and white chocolate across each cupcake, then pull a toothpick through the layers to create web lines. They're just what you need for Halloween parties, offering both a fun look and a deep, chocolatey taste that guests can't resist.

Everyone remembers when they first tried these Halloween spider web chocolate cupcakes. They always grab all the attention at kids' birthday bashes and adult get-togethers. With sweet, overripe bananas and a cool pattern made from swirled white and dark chocolate, they're just as fun to whip up as they are to munch on.

I first whipped these up during a rainy October evening when my son wanted something spooky to take to school. They quickly turned into our yearly tradition, and now my friends always ask me to bring a batch to their fall gatherings.

Round Up Your Ingredients

  • Ripe bananas: smashed up to add sweetness and keep everything moist. Go for ones with lots of brown spots for the strongest flavor
  • Buttermilk: adds a slight zip and makes the cake extra soft. No buttermilk around? Just mix some regular milk with a teaspoon of lemon juice and wait five minutes
  • Large eggs: hold everything together. Try to use them at room temp for better mixing
  • Cold water: makes sure your batter stays nice and wet
  • Vegetable oil: helps your cupcakes stay soft for several days. Pick one without much flavor
  • Golden caster or granulated sugar: adds sweetness and creates that nice soft texture
  • Plain all purpose flour: gives your cupcakes structure. Give it a quick sift for extra fluffiness
  • Cocoa powder: brings that yummy chocolate flavor. Dutch process makes them darker and smoother tasting
  • Bicarbonate of soda: helps everything puff up nicely. Make sure yours isn't too old
  • Salt: makes all the sweet stuff taste even better
  • Dark chocolate: melts down for flavor and for making web lines. Get one with at least 70% cocoa for good snap
  • White chocolate: creates those eye-catching webs on top. Buy a decent baking bar that'll melt smoothly

How to Make It

Preheat the Oven and Prep Trays:
Warm up your oven to 180°C or 350°F. Line two muffin tins with 16 cupcake liners so they're good to go once your batter's mixed
Mash the Bananas:
Put your bananas in a large bowl and squish them completely with a fork. The smoother they are, the better your batter will turn out
Mix Wet Ingredients:
Add the buttermilk, eggs, water and oil. Stir them together gently until everything's combined without any big lumps
Add Sugar and Dry Mix:
Stir in the sugar first. Then dump in your sifted flour, cocoa, bicarbonate of soda, and salt. Fold everything together just until mixed. Don't worry if it seems thin - that's exactly right
Fill and Bake Cupcakes:
Pour the mix into your cupcake cases, filling each about two-thirds full. Bake around 20 minutes until a toothpick stuck in the middle comes out clean
Cool the Cupcakes:
Let them rest in the pans about 5 minutes, then move them to cooling racks so they can cool completely before you start decorating
Melt the Chocolates:
Melt your white chocolate in one bowl and dark chocolate in another. Use short blasts in the microwave or a double boiler. Stir often for a glossy finish
Create the Spider Web Design:
Take a cooled cupcake and spread some white chocolate on top. Drop three or four circles of dark chocolate over it, then put a dot in the center. Pull a toothpick from the middle outward to create web lines. Do this with all your cupcakes, switching between white or dark bases for variety. Enjoy right away or let the chocolate harden

I love watching my kids' faces as they swirl those spider webs. They get so excited each time, and I don't mind them getting their hands a bit chocolatey. Anyone who bites into these is always surprised by how the bananas make them so flavorful and moist.

Flavor Boosters

Make sure cupcakes are totally cool before putting them away so they stay soft. Store them in an airtight container at room temp for a couple days. Put them in the fridge to last longer, but let them warm up before eating. Want that melty chocolate feeling again? Just pop them in the microwave for a few seconds.

Serving Suggestions

Stick a plastic spider on each cupcake or sprinkle some orange candy bits onto the chocolate while it's still wet. They go great with warm apple cider or as the main attraction at your party. You can also pour this batter into a big pan for an awesome spider web sheet cake.

Creative Twists

Try adding a dash of pumpkin pie spice for more fall flavor. Or replace some of the buttermilk with spiced apple cider for another autumn touch. For grown-up parties, add some edible glitter for a magical look.

Year after year my friends beg me to make these chocolate spider web cupcakes again. They tell me their children never want cupcakes from the store once they've helped create spider webs themselves. My cousin even took them to her work party and couldn't believe all the praise she got, especially from people who normally avoid anything with bananas.

Common Questions About This Recipe

→ How do I achieve the spider web design on cupcakes?

Get both dark and white chocolate melted in separate bowls. Cover the cupcake with one type, add three rings with the other color, and pull a toothpick from the middle outward to make the web pattern.

→ Can I substitute bananas in the cupcake batter?

You can swap bananas for some apple sauce or pumpkin puree to keep the cupcakes moist with a different flavor twist.

→ What's the best way to melt chocolate for decorating?

Pop it in the microwave for 30 seconds at a time and stir between each round, or try a water bath for slower, more even melting.

→ How can I store the decorated cupcakes?

Put them in a sealed container at room temp for a couple days, or stick them in the fridge if you want them to last longer.

→ Can I make these cupcakes gluten-free?

Sure thing, just swap out regular flour with your go-to gluten-free flour mix for great results.

01 3 small overripe bananas, mashed
02 3/4 cup buttermilk
03 3 large eggs
04 1 cup cold water
05 2/3 cup minus 2 teaspoons vegetable oil
06 1 3/4 cups granulated sugar

10 1/4 teaspoon salt

11 7 ounces dark chocolate
12 7 ounces white chocolate

How to Make It

Step 01

Get your oven running at 350°F. Put paper liners into sixteen spots across two cupcake trays.

Step 02

Grab your bananas and squish them completely in a big mixing bowl until you've got a smooth mush.

Step 03

Pour in your buttermilk, crack in the eggs, add the cold water, and dump in the vegetable oil with your banana mush. Hand whisk everything until it's all mixed up good.

Step 04

Dump in your sugar and give it a good stir. Next, add your already sifted flour, cocoa powder, baking soda, and salt. Mix it all gently until you can't see any dry stuff anymore.

Step 05

Scoop your batter into each paper liner, making sure they all get about the same amount.

Step 06

Stick them in the hot oven for about 20 minutes. They're done when you poke one with a toothpick and it comes out clean.

Step 07

Take your cupcakes out and let them sit in the trays for 5 minutes. Then move them to wire racks to cool off completely.

Step 08

Melt both chocolates in different bowls. Put them in the microwave for 30 seconds at a time, stirring between each zap. You can also use a double boiler if you want.

Step 09

Cover a cupcake with melted white chocolate. Then make three circles on top with dark chocolate. Put a dot in the middle and pull a toothpick from center outward to make a web pattern. Do this for all cupcakes, switching up which chocolate goes on the bottom.

Step 10

Enjoy them while the chocolate's still gooey or wait until it hardens up. Your choice!
