These spider web cupcakes deliver a moist chocolatey base topped with fluffy chocolate frosting and a gooey homemade marshmallow web that looks eerily real. They are a showstopper at Halloween gatherings and always draw requests for the recipe from adults and kids alike.
I first tried these cupcakes with my daughter for her classroom Halloween party and found the marshmallow web technique as fun as it is delicious. Kids love stretching the marshmallow and swirling it into haunted spider webs.

Instructions
- Prepare the Pan and Preheat Oven:
- Line a 12-cup muffin pan with cupcake liners and preheat your oven to 350 degrees Fahrenheit or 175 Celsius so your cupcakes bake evenly from the start
- Mix Dry Ingredients:
- In a large bowl whisk together flour cocoa powder baking powder and salt making sure there are no pockets or lumps for a uniform texture
- Cream Butter and Sugar:
- In a separate bowl use an electric mixer to beat the butter and sugar until very light and fluffy at least three to five minutes as this builds a tender cupcake
- Add Eggs and Vanilla:
- Break eggs into the creamed butter mix one at a time beating thoroughly after each then blend in vanilla extract until completely smooth
- Combine Wet and Dry Ingredients Alternately with Milk:
- Add half the dry mix to the wet ingredients then add half the milk mix gently then repeat finishing with the rest of the dry mix this gentle process keeps the crumb tender
- Fill Liners and Bake:
- Spoon or scoop batter evenly into the prepared liners filling each about two-thirds full for even domed tops and bake for sixteen to eighteen minutes until a toothpick comes out clean let cool on wire rack
- Make the Frosting:
- Beat softened butter for at least one minute then gradually sift in powdered sugar and cocoa powder mixing on low to prevent clouds then add milk vanilla and salt beat until fluffy and spreadable
- Frost Cupcakes:
- Once cupcakes are completely cool spread or pipe frosting generously on the tops making swirls or peaks as you prefer
- Make the Marshmallow Web:
- Place the mini marshmallows in a microwave safe bowl and heat for fifteen to twenty seconds until melted and gooey then stir well
- Stretch and Drape the Web:
- Cool the melted marshmallow very briefly until it is tacky but not hot then pinch off a small amount stretch it between your fingers and drape back and forth over each cupcake in a web pattern repeat until every cupcake is covered to your liking
- Decorate:
- Add candy spiders edible glitter or other decorations to enhance the spooky web effect and personalize your cupcakes

Mini marshmallows are my absolute favorite here their stretchy texture is magical for crafting edible webs The first Halloween I made these cupcakes my youngest got sticky marshmallow everywhere and declared them the best dessert ever
Storage Tips
Keep leftover cupcakes in an airtight container at room temperature for up to three days If you want to make them ahead bake the cupcakes and freeze unfrosted Marshmallow webs are easiest when assembled shortly before serving to keep them looking fresh The frosting holds up well in the fridge but let cupcakes return to room temperature before enjoying
Ingredient Substitutions
If you need these gluten free use a cup for cup gluten free flour blend instead of all purpose For a dairy free version replace butter and milk with plant based alternatives like coconut oil and almond milk Note that marshmallows often contain gelatin so check for a plant based brand if needed To deepen the chocolate flavor toss dark chocolate chips into the batter
