Halloween baking is one of my favorite things about fall, and these Spider Brownies are always such a hit! They start with a simple box of brownie mix (no shame in a shortcut, Moms!) and get the cutest spooky spiderweb frosting right on top.
I didn’t like chocolate a lot as a kid, but the older I get the more I love it. My husband, however, doesn’t like chocolate at all… which honestly just means more for me!! Haha!
These brownies are PERFECT for Halloween. They make the best dessert to take to a Halloween party, a school treat, or just a fun weekend baking project with your kiddos. The spiderwebs don’t have to be perfect to be adorable!
Here’s the recipe:
Ingredients:
1 box of brownie mix, any brand + box brownie ingredients
small sandwich baggy
Directions:
Preheat the oven to 350 degrees and line an 8×8 baking dish with parchment paper or foil (if you’re using foil, spray with non-stick cooking spray).
Combine the brownie mix and ingredients.
Pour the brownie batter into the baking dish and bake for 45-50 minutes.
Insert a toothpick in the center of the brownies around 45 minutes, if it comes out clean the brownies are done.
Remove from the oven and let cool.
Once cool, cut the brownies into 9 squares.
Scoop the frosting into a microwave safe dish and heat for about 10 seconds.
Fill the small sandwich baggy about 1/2 full with vanilla frosting.
Use the kitchen scissors to snip one corner.
Starting at the center of each brownie, gently squeeze the sandwich baggy and make a spiral with the frosting.
Use the toothpicks to drag the frosting from the center to the outer edges of the brownie.
Repeat with all the brownies.
Makes 9 brownies
If you prefer thinner brownies, bake in a 9×13 baking dish for 22-25 minutes.
Yield: 9 brownies

Tips for the Best Spider Brownies
- Make sure your brownies are COMPLETELY cool before adding the frosting. Warm brownies will melt the frosting and your spiderwebs will slide right off!
- Only warm the frosting for about 10 seconds. You want it just soft enough to pipe, not runny.
- Snip just a tiny corner off the sandwich baggy. You can always make it bigger, but you can’t make it smaller!
- Work one brownie at a time so the frosting doesn’t set before you drag the toothpick through it.
- Baking for a crowd? Use a 9×13 baking dish and bake for 22-25 minutes for thinner brownies that go further.
Spider Brownies FAQ
Can I use my favorite homemade brownie recipe instead of a box mix?
Of course! If you have a go-to from-scratch brownie recipe, use it. Just bake it in an 8×8 pan and follow the decorating steps the same way.
Can I make Spider Brownies ahead of time?
Yes! Bake the brownies a day ahead and store them covered at room temperature. Add the frosting spiderwebs the day you plan to serve them so they look their best.
What kind of frosting should I use?
Plain vanilla frosting from a can works perfectly. You want white or cream colored frosting so the spiderweb design really stands out against the chocolate.
How do I store leftover brownies?
Keep them in an airtight container at room temperature for up to 3 days. They probably won’t last that long though! 🙂
Are these good for kids to help with?
Absolutely! This is such a fun baking project to do together. Little ones can help squeeze the frosting bag (with some supervision) and bigger kids love doing the toothpick spiderweb part.

[…] be surprised at how easy they are. I can’t tell you the last time I used a box mix to make brownies. I can make them cake like or fudgy, it all depends on what crowd I’m making them […]
