Our school district has a wonderful schedule that allows for many breaks throughout the year for our staff and students. We always have a break for the first week in October and this is the first year we didn’t travel (not for COVID reasons, we just wanted to stay home and relax). But, without traveling, the boys wanted to do some crafts and fun things. Tyler saw a photo of a cobweb cake and we decided we could try to make one together.

We started with a chocolate cake and added a ganache to the top. I wanted it to be a dark color so the cobwebs would really stand out. Then we melted marshmallows to stretch across for the cobwebs. The cobwebs were the hardest part, but also the most fun part of the cobweb cake.

Due to my dairy allergy, we made this a dairy-free recipe. The cake was a devil-food cake that had no dairy in it. I used vegan butter, almond milk, and vegan chocolate chips. If you don’t have that allergy, then you can use the “regular” stuff to make yours.

Once we were done, the cake tasted like Hostess Chocolate Cupcakes, you know, the ones filled with marshmallow cream?

The marshmallow is very sticky, and it takes some practice to get it to stretch as you need. I found it best to stick one side to the cake stand, then stretch it across and stick the other side down.

Tyler helped me take some of the photos like he did when he made his Sprinkled Rice Krispies Treats. He thought it was a lot of fun to spin the cake stand and take a photo.

Cobweb Cake Step by Step

Ingredients

  • 1 1/2 cups powdered sugar
  • 12 tbsp butter, softened
  • 2 tbsp milk
  • 2 baked 8-inch round chocolate cakes
  • 12 oz chocolate chips
  • 12 oz marshmallows

Preparation

Place the cake rounds into the freezer.

Meanwhile, use an electric mixer to combine the powdered sugar, 4 tbsp butter, and milk until it forms a creamy frosting.

Take the cake out of the freezer and spread the frosting over one layer then place the other layer on top. You may need to cut the top off of the bottom cake layer to make it level so the other cake doesn’t break.

Place the cake back into the freezer.

In a medium bowl, microwave the chocolate chips and remaining 8 tbsp butter until melted.

Remove the cake from the freezer and place it on a cooling rack over parchment paper then pour half of the chocolate ganache over the cakes. The cooling rack helps the extra ganache fall off without pooling under or around the cake.

Let it stand for 10-15 minutes, until the ganache starts to harden before pouring the remaining ganache on the cake.

Let the cake stand for 1 hour while the ganache completely hardens.

In a large bowl, microwave the marshmallows on high for about 30 seconds, until melted when stirred.

Wear rubber gloves and gently pull bits of the marshmallow to stretch and lay over the cake.

Slice the cake carefully so the cobwebs don’t pull apart and serve.

Leftovers

We put the remaining cobweb cake in a container and place it in the refrigerator. It’s still too hot and humid here in South Texas to leave anything out with the potential to melt. It was good for another 2 days which was all the time it lasted at our house!
