Drawing spider webs on chocolate brownies couldn't be easier. That's why I like these brownies, they're super easy, almost effort-less treats you can make for your child's class or an office party or something like that.

What makes this recipe so yummy

  • Using a box brownie mix really speeds things up - plus they're not that bad. If you prefer though, you can make the brownies from scratch.
  • If you're not much of an artist (like me) then drawing a spiral on top of a brownie isn't too difficult and they look super cute. It's a simple frosting decoration.
  • These spider web brownies are perfect for a Halloween Party or a get together.

Groceries you'll need: Ingredients

Recipe walkthrough: Instructions

This is an overview of the recipe steps. For more detailed instructions visit the recipe card at the bottom of this post.

  • Step 1: In a medium bowl prepare the brownie mix per the package instructions.
  • Step 2: Pour mixture and bake in a square pan in the preheated oven for about 25 minutes.
  • Step 3: Remove the baked brownie and allow to cool completely on a cooling rack, then cut into 9 even squares with a table knife.
  • Step 4: Mix the icing ingredients in a large bowl with a hand mixer at medium speed. (Add more cream if you need the icing wetter or add more powdered sugar if it's too wet.)
  • Step 5: Pipe a spiral pattern of icing on top of each brownie then using a toothpick scratch a line from the center of each spiral outward, do this about 5 times.

Hint: You'll want to have your toothpick ready. Don't wait as the icing will dry quickly then you don't get the same effect as the toothpick will just cut through the icing instead of dragging it with it.

Recipe variations and substitute ideas

  • Homemade brownies - if you have a favorite brownie recipe and prefer to make them from scratch you can do so.
  • Semi sweet chocolate chips - add a handful of semisweet chocolate chips to the brownie batter.
  • Store-bought Frosting - you can buy the little pouches of icing at the store to decorate the spider web design. I'm not sure how hard it will set though.
  • Cream Cheese Frosting - you could make a cream cheese frosting.
  • White chocolate Frosting - you could use this too.

I used a 9x9" square baking tin to bake my brownies. You could use an 8x8 if you like your brownies a little taller.

You'll need a hand mixer and some mixing bowls too. As well as a piping bag with a small tip (Wilton #1).

How to store leftovers

Once the brownies have been prepared store in an airtight container at room temperature for up to 1 week.

They do freeze well, but I recommend freezing the brownie itself before you ice it, then add the icing on the day you wish to present them.

Mel's kitchen notes

Do not overbeat the brownie batter or you will incorporate air which will make it rise more, but then it will sink in the middle after and you'll have an uneven brownie square with high sides.

If you don't have a piping bag at home you could use a resealable disposable bag (zip-lok type plastic sandwich bag) and put the icing in there, then snip the corner of the bag. It will work just as well as a piping bag.

Frequently asked questions: FAQs

How can I stop the brownies from sticking?

Make sure to grease the brownie tin well with cooking spray before you add the brownie batter. I actually like to add parchment paper, which helps in lifting out the brownies too.
