These Halloween Brownies are as adorable as they are delicious! Quick and easy to make, these spooky brownies are the perfect addition to any Halloween party.
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.

Notes
*White baking chocolate will taste the best, but it may not harden unless stored in the fridge. I recommend using Ghirardelli White Melting Wafers, which taste much better than most candy melts and will allow you to store the Halloween Brownies at room temperature, even stacked, without ruining your piping. Please note that if using candy melts, you'll need to move quite quickly while piping, as candy melts seize up and set very quickly, especially if your kitchen is cold. Try melting the candy melts in batches to prevent them from solidifying too quickly in your piping bag. I don't recommend using white chocolate chips for piping. More on this in the Sprinkle of Science box above the 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.
