How to Make Life-Size Sugar Skulls

Making sugar skulls with a Wilton Nonstick 3D Skull Pan results in a super-cool life-size sugar skull! In the photo below you can see how much bigger the Wilton sugar skulls are (middle, back row) than the other sugar skulls.

Sugar skulls are made in Mexico in the weeks leading up to the Day of the Dead (Dia de los Muertos in Spanish), and are given as colorful gifts or as offerings to the dead. In recent times, sugar skulls have come to symbolize the Day of the Dead, and people all over the world are making sugar skulls and adding their own twist.

Colorful Sugar Skulls

Sugar skulls are traditionally made using melted sugar, but this tutorial uses a simple, safe recipe that anyone, even children, can use. Sugar skulls are usually much smaller, but when I came across the Wilton Nonstick 3D Skull Pan (this links to Amazon and gives us a small commission, which supports this site) I couldn't wait to try making life-size sugar skulls. The Wilton mold was designed for Halloween-themed cakes, but with a little improvization, they produce magnificent sugar skulls, like the 2 you see above.

If you'd like to make the smaller skulls, seen in the top photo, check out our How to Make Sugar Skulls page.

What you'll need

  • Wilton Nonstick 3D Skull Pan
  • Fine Granulated Sugar
  • Powdered Sugar
  • Meringue Powder
  • Water
  • Aluminum foil (or something similar)
  • Large sheet of cardboard or solid cutting board (anyting flat that can hold the sugar skull when it comes out of the mold).

Meringue Powder

Meringue Powder

Meringue powder is made from dried egg whites and is very important (especially with a life-size sugar skull) in forming a hard, solid skull. Without it, your skull would be too fragile to handle. Most brands of meringue powder available in supermarkets aren't strong enough for sugar skulls.

The best meringue powder for skulls is made by CK Products. You can find a local supplier through the CK products website.

The Wilton Nonstick 3D Skull Pan is designed for cake-making, but it's well-suited to making life-size sugar skulls. As you can see, it's large and sturdy.

Step 1: Mixing

When making sugar skulls, the measurements are very simple: for every 1 cup of sugar, add 1 tsp of meringue powder and 1 tsp of water.

To make one life-size sugar skull you need 10 cups of sugar, 10 tsp of meringue powder, and 10 tsp of water. That's quite a lot of sugar, so if you don't have a huge mixing bowl, you may need to do several smaller batches.

First, mix the sugar and meringue powder together and then add the water. Mix with your hands until all the sugar is moistened by the water. It takes a while and it feels like there isn't enough water. But you don't want it too moist because it will stick to the mold. It should feel like beach sand and be able to hold it's shape when you squeeze a clump and make an indentation with your thumb. If it won't hold together it's too dry.

Step 2: Filling the Mold

The front and back parts of the mold are filled in differently.

The Wilton Nonstick 3D Skull pan was designed for cake-making, which presents a problem. The back part of the mold was designed with a spacer on the back, which is supposed to be cut off after baking, before the two sides are glued together (see image on right).

It's easy to cut off this section when it's a cake, but not when it's a drying sugar skull, which can be hard on the outside, and soft in the center. Instead of cutting off the extra section, we're going to use aluminum foil to separate the main part from the section that is supposed to be cut off.

The front part of the mold (on the left side) can be filled in normally. Press the sugar into the mold as hard as you can and fill it to the top. The back part of the mold (on the right side) should only be filled in to the ridge. 

Fill the front (left) mold to the top.

Take some aluminum foil and lay it over top of the back part. Bend it to conform with the shape of the mold, so you know where to cut. Trim the foil with scizzors so that it will fit in the mold.

Now it's time to fill up the rest of the mold, so that it won't collapse when you flip it over. Because this back part will just be removed after drying time, you don't need to worry about longevity. So just mix up 4 cups of sugar and 4 tsp of water (no meringue powder). Pack that tightly in the mold on top of the aluminum foil.

Note: the mold is quite heavy when full, so if you think you might struggle to lift it up and flip it over, you should fill and flip one side at a time (or find a strong person to do it for you).

Step 3: Scrape off excess sugar

Now that both sides of the mold are full, you need to scrape off any excess sugar so that the surface is flat and even.

Step 4: Flip over and remove the mold.

Place the chopping board (or whatever flat surface you're using) and, while holding it tightly in place, flip the mold over and carefully place it down. Now slowly lift off the mold to reveal your life-size sugar skull.

Step 5: Drying and Scooping

Let your skull dry for 5 to 6 hours, by which time the outside will be hard enough to handle, but the center will be soft enough to scoop out. Scooping out the center of both the front and back parts of the skull is important because it makes the skull lighter, helps it dry properly, and makes the two sides easier to glue together.

Important: Don't make sugar skulls when it's raining or humid because they won't dry properly. If you live in a humid climate like me, make your skulls in an air-conditioned environment.

First, remove the back part of the skull from the section you isolated with the aluminum foil.

Treat the parts with great care because they are still very fragile. Scoop out the middle, staying away from the neck, and leaving a 1 inch gap to the edge.

After you're done, give your skull another 6 hours to dry before moving onto steps 6 & 7.

Step 6: Preparing the Royal Icing

Royal icing dries really hard (no need for refrigeration) and acts as a strong adhesive. In addition to using it later as a decoration, you're going to use it to glue the front and back parts of the skull together.

The recipe consists of 1 pound of powdered sugar, 1/4 cup of meringue powder, and 1/3 cup of water. This will give you enough to glue at least 6 life-size skulls. Adjust the measurements if you're making fewer skulls.

Mix the ingredients together in a large bowl using an electric mixer or a wooden spoon or spatula (which takes more effort) for 5 to 10 minutes until the icing peaks. If your icing isn't thick enough the back part of the skull will keep sliding off the front part.

Step 7: Gluing the Sides Together

Now that your skull has dried for another 6 hours it's time to glue the front and back parts together.

Use a knife (or pastry bag) to apply the royal icing to the front skull only. Apply a good amount because any extra will be squeezed out the side and wiped off.

Now press the parts together to form a complete skull and run your finger along the edge to spread or remove any surplus icing. Don't worry if some icing gets stuck on the outside of the skull because it will be covered by the decorations.

You'll notice that the back part doesn't match the front to form a perfect skull. The back part helps create the illusion of a complete skull, but mostly acts as a stand that props up the front part of the skull for optimal display.

Now you're done making sugar skulls! Let's see how they look.
