How to Decorate a Store Bought Cake for Halloween

We’re sharing how to decorate a store-bought cake for Halloween today!

Truth be told, when I first started thinking about how I wanted to decorate a store-bought cake for Halloween I immediately imagined something festive or chocolate.

This series on decorating store-bought cakes for special occasions has definitely taken on a life of its own and I have you to thank for it!

We’ve decorated a store-bought cake for Easter and Independence Day together and I have such a pretty idea for a Christmas and Valentine’s Day cake too.

The thing is my niece and nephews are WAY into Stranger Things right now.

Although my personal preference would be a festive Halloween over a spooky one – they are all about the spooky.

And since I’m bringing dessert to my family’s annual Spooky Soiree, I decided to surprise them with a store-bought cake for Halloween they would never forget.

Here’s a look at how to decorate a store-bought cake for Halloween…

Store Bought Cake for Halloween Supplies:

  • Store Bought Cake (normally available in the refrigerated cases of your local grocery store bakery)
  • Festive Halloween Embellishments (we chose spooky hands, but witch’s legs or hat would also be cute)
  • Sandwich Cookies (we used Oreos)
  • Spray Candy Blood, optional
  • Cake Plate
  • Food Processor or Blender

Store Bought Cake for Halloween Steps: 

Before you get started, gather your supplies and set up your workstation.

Remove the store-bought cake from the box or container and lay it on top of your cake plate.

While the cake is resting, place sandwich cookies of your choice into a food processor or blender.

Some of the cookies will need to be chopped. While others need to be finely ground so they resemble dirt.

Sprinkle the “dirt” around the base of the cake.

Next, add your festive embellishments.

We found these skeleton hands at Michaels on sale.

Once the festive embellishments are secure, sprinkle the chopped sandwich cookies on top of the cake.

Basically, I wanted it to look like the hands were coming out of the “ground” and were covered in “dirt.” But you can do whatever works best for your theme or party.

As I shared above, using witch’s legs (like she was diving headfirst into the store-bought cake for Halloween) would be cute too. 

After you have the festive Halloween embellishments and the cookie crumbles in place, add candy spray blood, if you like.

We also picked the candy spray up at Michaels.

It’s cherry flavored.

Again, feel free to decorate with what you like best. I wouldn’t normally do anything this creepy.

But it’s a really simple way to get on board with the things the littles (who are actually tweens) are into right now.

After all, family get-togethers are about making memories. Especially, this time of year!

And I know decorating this store-bought cake for Halloween is going to be something they’ll not only appreciate but will also always remember!
