Halloween Spider Bundt: So easy, your mummy could do it!

It’s time to let the creepy crawlies in on the fun! Every year King Arthur Flour bloggers MJ and Gwen get together to play around in the kitchen, creating spooky cute creations for Halloween. This year’s winner takes the cake — literally! Halloween Spider Bundt cakes are beyond easy, and so much fun for both kids and adults to create. Let us show you how —

Halloween Spider Bundt Cake is scary simple! Get started:

All you need is a chocolate or vanilla Bundt cake, baked in our Party Bundt Pan. Or bake both!

We’ve baked Mini Chocolate Bundtlette Cakes and Golden Vanilla Pound Cake, both in full-size 10-cup Bundt pans. Start checking them after they’ve baked for 50 minutes; they’re done when a toothpick inserted in the center comes out clean.

Note: before baking, remove 1/4 cup of the batter and bake it in a muffin pan to create a separate cupcake. You’ll see why later.

Choose your frosting

Our frosting of choice is Easy Vanilla Buttercream Frosting, which will easily frost two cakes. For chocolate frosting, split your batch of vanilla frosting in half, and add 1/4 cup Dutch-process cocoa plus 1/4 cup black cocoa to one half, mixing well. BAM. Instant chocolate frosting!

Round up the candy

Your spider needs some features! The following are good choices:

  • Colorful chocolate candies
  • Candy corn, for the fangs
  • Licorice shoe strings, also for the fangs and equally spooky
  • Large red cinnamon candies

Other helpful tools:

  • Piping bags and tips; we used a Wilton 1A tip, which we found made the perfect sized spider legs, but feel free to use your favorite large mouthed tip
  • Toothpicks

Assemble the spider’s body

Take the separately baked cupcake and insert it into the center of the Bundt, creating the body of the spider. If you’d rather fill the middle of the cake with ALL frosting (the more frosting, the better, right!?), follow the directions in the recipe for increasing the amount.

Pipe the top of the cupcake with frosting, to make the body of the spider.

At this point, be sure to have your cake on the plate you intend to serve it on. Once the legs are in place, it can no longer be moved without damage.

Pipe the legs

Using the toothpicks, lay out where you intend to pipe the spider’s legs. We left three cake columns free for the face, and left two columns between each leg.

Starting from the top, slowly and smoothly pipe the frosting up and down to the bottom. Twisting your arm to the side as you travel down, keeping your arm flat instead of straight up, will prevent the tip from flattening and keep your frosting legs nice and round. Be sure to leave a nice blob at the bottom, for the feet. Remember to remove the toothpicks one at a time before piping.

Add the face

Now for the fun of decorating! We styled our two Halloween Spider Bundt cakes differently, placing the face on the front of the cake for our chocolate spider, and on top for the vanilla one. Choose whichever you prefer, or make up your own style face.

To attach candies to the front of the cake, pipe about a teaspoon of icing in between the column in the center of the front (left photo, above).

Angle the eye candy (pun intended) to create the expression you’d like. We decided that turning the oval M&M’s slightly gave our spider a mildly sinister look, but nothing too scary.

Press the candy into the soft icing and hold for just a moment to let it settle. Repeat with the fangs. By altering the angle of the candy corn fangs, we softened the expression just a bit, keeping our spider from looking too deadly.

For the vanilla spider we chose large red cinnamon candies to really pop against the white icing. Bright traditional candy corn pushed lightly into the feet made excellent toenail claws. With all the unusual candy corn flavors out these days, you could really jazz up eight little feet easily!

    Love these! I’m wondering how to adjust the baking time to make them as brownies rather than chocolate cake. Any ideas?

    1. Joy Hill

      Buy mini bundt pans (like cupcake pans) and use a chewy brownie recipe. They’d be adorable! Good Luck!

    2. Debra

      Bake your brownie batter in a muffin tin with angled sides. You should get the slanted sides that will let you make it look like a spider.

      I have an ancient 6-cup muffin tin that has a fluted interior similar to a Bundt pan. It would make great Mini-Brownie Spiders. I did a quick Internet search for “fluted muffin pan” and turned up many sources for them.

      The benefit of baking in a muffin or cupcake tin is that the baking time is dramatically reduced and your multiple spiders could be arranged into a decorative swarm.

    Man, oh man, I’m going to have to do this one !!!! I love getting all your emails and posts, you people are fabulous !!!!!!!!!

    This is so cute! I’d like to do the chocolate version, using the mini bundt recipe in my Party Bundt Pan. How long did you bake it, and at what temp.?

  4. Carma Rogers

    I did it yesterday. I actually had to take out 2 cupcakes’ worth of batter. (My husband “needed” a cupcake since the cake was going to work.)
    My bundt pan is more angular, so it looks like the spider is sitting on top of a pine cone. Eyes and the tips of the feet are small cinnamon chips. I was going to do multiple chips for the eyes but it would have been too crowded.
    Pleased to say it turned out very nicely.

      So glad to hear it worked so well, Carma. I wish I’d thought of the two cupcake idea when we were testing! The cinnamon chip footies sound delish too. Great work! ~ MJ

    I made this cake, but didn’t want to buy black food coloring, so tried to make my own. It turned out to be a pretty disgusting “Halloween green”. My seven year-old grandson was horrified. He thought I had used green beans instead of frosting!

      Martha, sounds like your grandson got an unexpected Halloween scare! Green bean frosting is a little terrifying. I hope he recovered enough to enjoy the cake! Barb@KAF
