Make the Brownies:

1. Prepare a batch of Best Ever Chewy Brownies according to your preferred recipe.
2. Allow the brownies to cool completely. If you have time, chill the brownies until firm to make slicing easier. Once chilled, slice the brownies into 9 large pieces or 16 smaller pieces.

Melt the Candy Melts:

1. In a microwave-safe bowl, melt the white candy melts or white baking chocolate in the microwave at 50% power. Stir every 30 seconds until fully melted and smooth. Alternatively, you can melt them using a double boiler.
2. Transfer the melted candy or chocolate into a disposable piping bag or a zip-top bag fitted with a small piping tip, like Wilton #3. If you don’t have a piping tip, you can snip a small hole at the end of the bag.

Decorate the Brownies:

1. Take one brownie slice at a time and pipe crisscrossing lines on each one to create a spiderweb pattern. Pipe curved arches connecting the lines to complete the look.
2. Repeat the process for all the brownies.
3. Allow the spiderweb decorations to dry completely.

Store the Brownies:

1. Once the spiderwebs have dried, place the brownies in an airtight container. Use pieces of parchment paper or wax paper between the stacked layers.
2. Halloween brownies can be stored at room temperature for up to 3 days, or refrigerated for up to 5 days.
