My older nephew loves imagining that he’s a master Quidditch player and inventor of superior racing brooms, so I decided to make him a snitch for Christmas, which is also a secret treasure box. Of course, it had to be oversized, because otherwise he couldn’t keep anything in it larger than the Resurrection Stone.

I began with two wooden bowls from Ikea that were perfectly sized and shaped. The wings are make of strips of ribbon on a tulle base, wrapped over bent brass rod. All the trim on the sphere is model magic. The catch is magnetic.


Lord Voldemort Pumpkin

*2016-10-29 23.29.11

I somehow never seem to have much time for pumpkin carving these days, probably because I now spend the month of October making Halloween costumes for my nephews. But this year we decided to go the store-bought route for our Harry Potter costumes, so I had a little time. I wanted to practice my 3-d pumpkin sculpting, so I made this little Lord Volde-pumpkin.

Cars Pit Crew Cake

My little friend Isaac really likes the pit crews from Cars. Fortunately, if there is one thing I’m good at, it’s making anthropomorphic vehicles out of gum paste. Over the years, I’ve had a lot of experience.

Because I also like to build automata, I decided to make the pit crew dance.

I really wanted to make it voice activated, with a headset like the pit crew boss. I have successfully made a voice activated automaton before, but for some reason I couldn’t get this one to work so I had to settle for a switch. In the end, the switch was probably better because it was easier for Isaac to use than the voice activation would have been and he really enjoyed turning it on and off while carefully examining the mechanism.

The actual cake is the tires behind the pit crew. They’re a basic sponge cake with a raspberry or blackberry jam filling, with modeling chocolate treads, dipped in dark chocolate.

They were kind of like really fancy Donettes. Which is to say they were fabulous. If I do say so myself.

History of Life Wedding Cake

*2016-09-03 10.34.32

This is the third wedding cake that I have ever made. Which means that, amazingly, there are three couples in the world with that level of trust in me.

The bride is in law school and the groom is a paleontologist. The wedding was on September 3, which is the anniversary of the signing of the Treaty of Paris, which, as everyone knows, if the treaty that ended the American Revolutionary War and in which Britain recognized the United States as an independent nation. Just kidding, I had no idea what the Treaty of Paris was; I had to google it.

This is the design we came up with.

*wedding cake sketch 6_29_16

Each tier represents an era of the evolution of life on Earth – Paleozoic, Mesozoic, and Cenozoic. The tiers get progressively shorter as you move up the cake, to suggest the shorter duration of each era. The overall shape is meant to evoke this kind of spiral shape that is often used in images describing the history of life.

Each tier has a “couple” on it, as well as other iconic forms of life from that era. The Paleozoic tier has a couple of trilobites.

*2016-09-02 16.16.06

The Mesozoic era features a Tyrannosaurus Rex chasing a fleeing pair of pterosaurs. Note the T-Rex’s feathers.

*2016-09-02 18.14.04

And the Cenozoic era tier has a megatherium (which is kind of giant prehistoric ground sloth) and a couple of hyaenodont skeletons (the groom’s PhD dissertation centered on hyaenodonts).

*2016-09-02 22.30.18

On top of that tier walks a couple of Australopithecus, which I’m told is something that the groom has been imagining on his wedding cake since he was a little boy. It’s inspired by these fossilized footprints that suggest that an Australopithecus might have walked next to each other, hand in hand.


The cake is covered with a mix of fondant and modeling chocolate and all of the figures are sculpted out of modeling chocolate colored with powdered food coloring. I made all the large figures in advance, over forms made to mimic the curvature of the cake tiers. That way I could make them well in advance and bring them in my carryon, since I had to fly cross-country for the wedding. (I didn’t fly with the whole cake. I arrived three days early and rented an Air BNB with a full kitchen to do the actually baking and assembly.

*2016-08-24 01.28.46

For the smaller fossils and bones at the base of each tier, I made molds out of food-safe silicon, so that when I assembled the cake I could just push some fondant into the mold and stick it on the cake.

Of course, Australopithecus would have been nude and the couple understandably didn’t want exposed genitalia on their wedding cake. They also wanted to incorporate the Treaty of Paris, so I was delighted to discover that the Treaty of Paris has a nice blue ribbon at the bottom, running underneath the signatories’ seals. So I made a replica of the Treaty of Paris for the top of the cake with a long ribbon on the bottom to wrap around the couple’s inappropriate bits. Although if you look closely at the above photo before I put the ribbon in place, you’ll see that I couldn’t resist making the Australopithecus couple anatomically correct.

It’s made of edible wafer paper with the actual text of the Treaty of Paris hand painted with food coloring. Of course it’s not the entire text, as the treaty is far too long for that. Using images I downloaded of the actual document, I photoshopped the signatures onto the bottom of the first paragraph. Then I printed it out at the actual size I needed for the cake. I turned this into basically edible transfer paper by coating the back of the paper with powdered food coloring. I put this on top of the wafer paper and transferred the text onto the wafer paper by tracing the printed image with a toothpick. Then I went back over the traced text with paste color and a detail brush. To get the graceful curve, I lightly sprayed the back of the wafer paper with water and then set it over and under a couple of rolling pins to dry.

*2016-09-02 13.56.04

The lowest tier and the dividers between the evolutionary era tiers are encircled with books, which are meant to bring in the bride’s studiousness. They also offered a great opportunity for personalization as the bride and groom sent me a list of all their most influential books. The dividers between the tiers are quite small and made so that they can be popped into place to conceal the cake’s internal support. Those books are just gum paste with the titles painted on.

*2016-08-28 19.58.14

The books on the bottom tier are much larger and can be seen from the top as well as the sides, so they required more detail to be convincing. So I made pages out of wafer paper and stuck them together with piping gel. Once that was dry, I wrapped each book in a gum paste cover and then painted the title onto the spine. In most cases, I was able to find real cover art from the book to base it on.

*2016-08-28 19.53.59

Inside, the cake flavors are vanilla, orange, ginger, and chocolate in alternating layers to suggest different strata of dirt. We wanted people to be able to have an archeological experience while eating the cake, so I buried chocolate fossils inside each layer. I made custom molds for the fossils, based on sculptures that I did representing various fossils that would have been common in each of the cake’s eras. With these molds, I cast the fossils in white, milk, and dark chocolate and then embedded them in the cake layers as I was stacking this cake. Then as the guests ate the cake, they got to excavate their chocolate fossils.

*2016-08-27 00.05.57

The drive from the Air BNB was about half an hour and not over the greatest roads. I enlisted the bride’s brother to help me deliver the cake, since he has an SUV with enough space. He is a former Army Ranger, yet apparently still found the pressure of the drive terrifying. I don’t blame him. I hate driving with cakes. We arrived at the venue without incident, though.

One of the groom’s paleontology friends created a museum card to accompany the cake, explaining all the different fossils, inside and out. He even gave a little introductory speech before they cut the cake. And apparently some of the groom’s paleontology colleagues even said my T-Rex was one of the best reconstructions they have ever seen in any medium. But, really, this photo is the best part.


Love Makes the World Go Round Cake


My friend’s granddaughter’s birthday party theme was Love Makes the World Go Round. So I came up with this cake, which is meant to suggest the earth traveling around the sun on an outer space cake board.

The color is all hand painted. The sun came out looking maybe a little more like a giraffe than a sun, but at least the overall effect is fun and colorful.


The earth is mounted on an aluminum strip that rotated freely around the post supporting the sun, so you can make the earth orbit around the sun.

Terraria Celestial Event Cake

011 20160319 Nathans 10th birthday party  DSC_2904

Nathan, for his 10th birthday, requested a Terraria celestial event cake, with a four-sided pillar, each side of which corresponds to a phase of the celestial event – Nebula, Stardust, Vortex, and Solar – and includes the appropriate monsters.

2016-03-17 23.51.32

Fortunately, after Sam’s last Terraria cake, I am expert at painting pixel-y gum paste Terraria characters. The guy on the side is Nathan’s avatar, with a Horseman’s Blade, which he specifically requested.

Nathan's avatar with giant sword. Note the individually hand-painted pixels.

The tower is cake, mounted on a pipe connected to a bevel gear, so that the cake can be turned with a crank.

I wanted to make the backdrop change color to correspond with the celestial event phase, so I made a light box like the one I made for the Terraria Blood Moon Cake. Inside are strips of LED tape in pink, yellow, blue, and green. When the cake turned, a strip of copper tape on the gear created electrical connections that lit the appropriate color LEDs as each side of the pillar came to the fore. It quite well at home, but the party was outside on a sunny day, so with that much ambient light the color change was virtually imperceptible.

Pink is the Nebula Pillar

As usual, I made about four times as much cake as the party required.

Terraria Blood Moon Cake

2016-01-16 21.21.08

For Sam’s 7th birthday, he wanted a Terraria blood moon cake. Apparently, when there is a blood moon, a lot more zombies come out and there are some kinds of zombies that only appear in the blood moon. So we settled on a design where the moon changed from blue (regular moon) to red (blood moon) and a bunch more zombies rose up out of the ground.

2016-01-16 20.54.41

2016-01-16 20.54.43

The characters are handpainted gumpaste. The blood moon zombies are all mounted on metal tubes that are attached to a little platform. The platform is lifted by fishing line attached to a wooden dowel, so that when the dowel is pulled out, the zombies rise up for the blood moon and when the dowel is pushed in, the zombies sink into the ground for the regular moon.

2016-01-16 20.54.47

Sam also wanted his Terraria avatar and the guide NPC, so I included a little house made of gingerbread where they can hide from the zombies and mounted them on a track so they can walk back and forth.

2016-01-16 05.48.03

The backdrop and the moon are light boxes with lids of plexiglass covered with fondant. Inside, are rows of red LEDs and rows of blue LEDs. The LEDs are wired through the platform that raises and lowers the zombies, so that the blue LEDs light when the platform is down (regular moon) and the red LEDs light when the platform is up (blood moon).

Pac-Man Halloween Costume

Nathan as Pac-Man. Costume by Leigh.

I’m not sure why Nathan wanted to be Pac-Man for Halloween. He may have played Pac-Man once or twice, but he hasn’t seen Pixels. The overall structure of the costume was his idea. It’s made of foam core and it has a removable compartment in the mouth so that he can collect candy in Pac-Man’s mouth. It’s also outlined in EL wire, for easy visibility trick-or-treating at night.

Dark Washbuckler Halloween Costume

*20151030 Halloween Ryan IMG_9910(1)_1

Sam is very into Skylanders games and he wanted to be Dark Washbuckler for Halloween, who is a kind of octopus pirate.

I started the costume with black sweatpants and a black shirt and trimmed them with silver. The six extra legs are sewn to an elastic waistband. The hat, belt buckle, mustache, and suckers on the tentacles are made of fun foam. The ladder logos on the hat and belt buckle are because Washbuckler is a climbing type. Sam insisted that there be two on the belt buckle. I’m not sure why. They have LEDs inside to help with trick-or-treating visibility.

Inside Out Cake

20151011 Inside Out cake DSC_1080

This Inside Out cake was for my friend Isaac’s ninth birthday, which is why it’s in the shape of the number 9.


The number 9 itself is mostly foam core covered with gum paste, because I needed room to embed LEDs and I didn’t need very much cake because they party was pretty small. 20151011 Inside Out cake DSC_1143

The memories around the edge of the 9 are gelatin bubbles, which are made by dipping partially inflated balloons, coated with shortening, into melted gelatin. They’re surprisingly sturdy once dry and technically edible, though it’s a little like eating plastic.


Each memory bubble contains a picture of the birthday boy, at ages from infancy to now, printed on edible wafer paper and each one has an LED behind it.

20151011 Inside Out cake DSC_1062

The figures are made of modeling chocolate with gum paste hair and clothes. They are made over a wire armature attached to a motor, so that they can spin joyously around.


The actual cake is the memory balls in the middle of the 9, which are cake balls dipped in royal icing and then in colored piping gel. I was trying to make cake that was easy to pick up and eat with no utensils, because the party was outside. But I didn’t leave enough time for the piping gel to dry, so they wound up extremely sticky and messy to eat. Still tasty, though.
