A CREEPY CRAWLY Cake

I have another fun and creepy creation to share with you today!

This one was inspired by the Chocolate Pudding Spider Pies we made a few years ago. Those are individual-size treats, and I thought it would be fun to make on big spider cake that was simple and delicious and perfect for all your Halloween festivities.

I love how festive it turned out and the kids LOVED how tasty it was. The best part is it’s very simple to make and doesn’t require too much baking skills.

In fact, I ended up using a cake box for the actual cake and then made an amazing homemade chocolate buttercream frosting to go with it.

The frosting made it so delicious along with the crushed Oreos all around it. At first, I had hoped to use black licorice for the legs but that wasn’t working so black card stock was my second option.

We loved the result, and I’m so glad it turned out. 😀 This cake really is perfect for any Halloween event you have coming up, and will be a hit with all the kids (and even the adults too). If you love chocolate and Oreos you’ll love this creepy, crawly cake!

HOW TO MAKE a Spider Cake

CAKE. Make cake as directed in box using two 8″ or 9″ circle pans. Let cool.

OREOS. Crush Oreos in a Ziploc bag and set aside.

FROSTING. Make frosting by combining butter, powdered sugar, cocoa, whipping cream and vanilla. Beat until all combined, add more powdered sugar if you want it thicker or more whipping cream if you want it thinner.

DECORATE. Frost cake and add crushed Oreos all over the cake (add chocolate jimmies for eve more texture). Add cinnamon candies to the front for the eyes. Place card stock legs in the cake right before serving and enjoy!

Note. I ended up cutting out one leg from black card stock and then tracing it to make seven more. I inserted these right before we served the cake so that they wouldn’t get messed up (or take up too much room in the fridge).

Tips + Variations

Have fun with the kids by dissecting the spider into individual servings.

Although this cake turned out perfectly creepy and delicious you can use a few of the following suggestions to switch things up:

  • For thin hairy looking legs use black pipe cleaners
  • Adding black/brown jimmies along with the Oreos may also give a hairy look
  • You can also use candy eyes 
  • Try using our homemade chocolate cake 
  • Use store bought chocolate frosting to save some time

Storing Info

Make this cake a day ahead of time and store, covered, at room temperature. If you don’t have a container big enough you can just cover the cake with a large bowl turned upside down or you can carefully tent aluminum foil over the cake. Before serving insert the paper legs. 

For longer storage I suggest FREEZING the cake and frosting separately. The cake can be wrapped tightly with plastic wrap then again with aluminum foil and kept in the freezer for up to 6 months.

Freeze the frosting, in an airtight container, for up to 3 months. Bring the frosting to room temperature, but you do not need to thaw the cake before frosting it. 

STORE the cake in the fridge or on the counter covered with a bowl. It doesn’t need to be kept in an airtight container because the frosting protects the cake, but a loose covering like a bowl will protect it from anything like dust or hair from falling on the cake.
