How to Make Halloween Brownies
The Best Brownie Recipe
My Best Ever Chewy Brownies recipe is one of the most popular recipes on my site – and for good reason! It’s a one-bowl recipe that’s super easy to make with ingredients you may already have in your pantry. For tips on making the most perfectly chewy, rich, chocolaty brownies you’ll ever taste, be sure to read through the Sprinkle of Science box above that recipe.
What Pan Do I Need for Baking Brownies?
- I recommend my go-to 8×8-inch metal pan.
- Do not use a glass pan to bake brownies – they won’t bake as evenly, and the edges might dry out before the center has baked through.
- Learn more about Glass vs. Metal Baking Pans article here.
How to Perfectly Slice Brownies
Check out my How to Cut Brownies Cleanly in 5 Steps article for all my tips on slicing brownies perfectly.
What Type of Chocolate to Use For The Cobwebs?
- White baking chocolate will taste the best, though it may not harden unless stored in the fridge. Although I love a chilled brownie (hello, extra chewy and fudgy!), that’s not always practical at parties.
- Candy melts harden at room temperature, and while I don’t prefer their flavor, it won’t be super noticeable over the richness of these brownies.
- If you’d like to use candy melts, I recommend using Ghirardelli White Melting Wafers, which taste much better than most candy melts. Candy melts will allow your brownies to stay unrefrigerated and can even be stacked without damaging the cobwebs.
- White chocolate chips may not melt as quickly, which can cause the chocolate to burn, so I don’t recommend those here.
Decorating Halloween Brownies: How to Pipe Spider Webs
- Melt white chocolate or wafers and transfer to a disposable piping bag (or ziplock).
- One brownie slice at a time, pipe four lines to form a snowflake pattern, stopping a little before the edges of the brownie.
- Join the ends of each line, arching in towards the middle as you pipe.
- Move halfway towards the center and pipe another series of arches between each line.
- If space, repeat this for a total of three arched lines. If there isn’t much space left, simply pipe a small circle in the middle, to finish off your spiderweb.
- Let dry and repeat for all brownie slices. Don’t worry about perfection!

Can I Double This Recipe?
Need to serve a crowd? Simply double all ingredients in my Chewy Brownies recipe and bake in a 9×13-inch metal baking pan, adding a few minutes to the bake time. You’ll need 2/3 cup (112 grams) candy melts or white chocolate for your spiderwebs.
How to Store Halloween Brownies
Brownies can be stored inside an airtight container for up to 3 days at room temperature or up to 5 days in the fridge. They are even more fudgy when they’re chilled! Please note that the edges of the brownies, once cut, will dry out quickly if not stored inside an airtight container.
Can You Freeze Halloween Brownies?
Halloween Brownies freeze beautifully and are the perfect treat to make ahead before your Halloween party! Simply wrap the whole slab or slices in plastic wrap and place in a freezer bag or airtight container for up to a month. Thaw overnight in the fridge or for a couple of hours at room temperature before decorating and serving.

Ingredients
- 1 batch
Best Ever Chewy Brownies - 1/3 cup (56 grams)
white candy melts , or white baking chocolate*
Instructions
Make the brownies:
- Make a batch of my Best Chewy Brownies.
- Allow to cool completely. If time allows, chill the brownies until firm. Once chilled, evenly slice the brownies into 9 large slices or 16 smaller slices.
Melt the candy melts:
- In a microwave-safe bowl, melt white melting wafers or white chocolate in the microwave at 50% power, stirring every 30 seconds, until melted and completely smooth. A double-boiler works just fine for this, if preferred.
- Transfer the melted white chocolate/melting wafers to a disposable piping bag or zip top bag fitted with a small plain piping tip such as Wilton #3, or simply cut a very small hole at the bottom of the bag.
Decorate the brownies:
- One brownie slice at a time, pipe crisscrossing lines on each brownie to create a snowflake pattern, then connect the lines with curved arches to form a spiderweb. Repeat for all brownies.
- Once the spiderwebs have dried fully, place inside an airtight container with pieces of parchment paper or wax paper between stacked layers. Halloween Brownies can be stored at room temperature for up to 3 days, or up to 5 days refrigerated.
