Looking for a fun and easy Halloween dessert? These Chocolate Spiderweb Cookies are rich and fudgy with a beautiful dark color thanks to black cocoa. Melted marshmallows are added on top to make them look extra spooky!

The dough comes together quickly and is scooped and placed on a parchment lined cookie sheet. They bake in about 10 minutes. Then it's just a matter of melting the marshmallows to add on top.
A FEW NOTES BEFORE WE GET STARTED
- Room Temperature Ingredients:
- Butter: It’s important that your butter is softened. In a pinch, you can put your butter in the microwave for about 5 seconds on each side, but watch closely to make sure it is just softening and not melting.
- Eggs: You'll want to make sure that the eggs are at room temperature to ensure that they are properly incorporated into your pudding and your cookies. If you forget to leave them out before you start, place them in a bowl of warm water for about 15 minutes until they become room temperature.
- Measuring Your Ingredients:
- I strongly encourage that you use a kitchen scale to measure your ingredients and ensure that you have the most accurate measurements possible.
- However, if you don’t have a scale on hand and will be using cup measurements, make sure to use the “spoon and sweep” method when measuring to avoid packing in too much of any dry ingredient.
Preheat oven to 350º F. Whisk the flour, black cocoa, baking powder, and salt together in a large bowl and set aside.
In a stand mixer fitted with a paddle attachment, cream together the butter, sugar, and melted chocolate on medium speed until light and fluffy. Scrape down the sides of the bowl.
Add eggs one at a time, followed by the vanilla extract. With the mixer on low, slowly add the flour mixture and mix until smooth, scraping down the sides of the bowl as needed.
Using a 2 tablespoon scoop, form cookies into balls and place each cookie a few inches apart on a parchment lined cookie sheet. Bake for 10-11 minutes or until cookies are firm around the edges.
Let the cookies cool for about 10 minutes on the baking sheet before carefully moving them to a cooling rack.
Place the marshmallows in a heatproof bowl and microwave for a few seconds. Stir and microwave for a few more seconds if needed.
Once the marshmallow is slightly cooled, dip your fingers into it and while hovering over the cookies spread them apart to create a web design. Carefully lower them down on the top of the cookie until they adhere to the top of it.
Repeat this process several times until you have a few layers of web. Repeat this process with the rest of the cookies. Enjoy!

Notes
- These cookies use black cocoa powder. In a pinch you can use regular unsweetened cocoa powder, but they're best with black cocoa. I like to use this black cocoa.
- Leftover cookies can be stored in an airtight container for up to one week but are best when enjoyed within the first few days.
- Cookie dough can be made ahead, scooped and placed in a ziploc bag to be frozen for up to two months. Once you’re ready to bake, let the dough sit at room temperature for about 15 minutes and bake. You’ll need to add on an extra 5 minutes or so to the original baking time.
