I’m all about quick, cute, and easy. I love making fun holiday treats for my kids and family, but often I just don’t have a lot of time. Or sometimes my kids will give me very little notice that they need to bring a treat or snack! Some of our favorites are Oreo Bats and Halloween Trail Mix–just minutes to make and so festive.
To make these all you need is a boxed brownie mix for a 9×13 pan, white frosting, and a toothpick. Really, that’s it! You can make it as quick and easy as you want. If you want to do homemade brownies and frosting, you absolutely can. Both ways will work, depending on how much time you have.
These are perfect for taking to a party, serving to your own guests and family, or a classroom party. They would also be so fun to use to go “booing”…and to say “You’ve Been Boo’ed!”
I also love this idea, because it’s so easy to make gluten-free. I have a daughter with celiac disease, and so I’m always on the hunt for fun recipes and holiday ideas that are easily adaptable. I just used two boxes of our favorite gluten-free brownie mix (affiliate link) and put them in a 9×13 pan.

Ingredients
- Boxed brownie mix, baked and cooled (or homemade brownies)
- White frosting
- Toothpick
I usually make homemade frosting and then use a piping bag, but for this I picked up an easy to decorate cookie icing at the grocery store. It’s a huge time saver for this recipe, but you can definitely do it either way.

How to make
Once you’ve baked your brownies, let them cool completely, then cut into squares. I find it easiest when I line my baking dish with parchment paper or aluminum foil, and let it hang over the edges. Then I can easily lift all the brownies out, trim the edges (which my kids eagerly scarf down), then cut into equal and even-sized pieces.
Pipe a circle spiral on the top of each brownie, starting in the middle.

Then take your toothpick and make lines through the frosting–from side to the other–kind of like you’re cutting a pizza.

That gives you the fun spiderweb pattern in literally minutes. LOVE!!!

FAQ
Absolutely! I suggest a brownie that’s not super ooey and gooey, or it might be more difficult to keep the spiderweb nice and clean.
I’d suggest a round tip, .2″, but you could do a little larger or smaller. You just don’t want it too big so there is enough space for the web when you put the toothpick through.

Storage & Freezing
If you plan to make the brownies ahead of time, let them cool and cut into squares. Place in an airtight container or freezer bag, and freeze for up to 3 months. When ready to thaw, place in the refrigerator until thawed. Add the frosting webs right before serving.
To store, keep in an airtight container for 3-5 days. If you’re not serving right away, wait to put on the webs until the day of, or a few hours before.
