Step 1: Ingredients & Equipment
4 cups of granulated sugar
3/4 cup of powdered sugar
1 egg white
Food coloring (gel, paste, or liquid)
*This amount will make one six-inch egg, or two three-inch eggs.
Pocket or paring knife
Piping bag and tips or sandwich bags and scissors
Egg-shaped mold which opens horizontally
Note: Meringue powder can be substituted for the egg white. Use one tablespoon of meringue powder to two tablespoons of water; however, be very sparing as you add this mixture. It tends to be wetter than egg white and your sugar egg will take much longer to dry.
Step 2: Color the Sugar
In a small bowl, mix the egg white with food coloring until the color is evenly distributed and the egg is frothy. Err on the darker side with your dye, because the color will become lighter when mixed with the granulated sugar.
Next, pour the egg white/color mixture into all four cups of granulated sugar with 3/4 cup of powdered sugar. Stir until all of the liquid is incorporated evenly. At first, it may seem that there's not enough liquid, but keep stirring and all of the sugar will be damp.
The mixture should be moist enough that you can squeeze it into a ball that holds it's shape, but very dry and sandy.
Step 3: Create the Egg Shape
Fill your egg mold with the sugar mixture, pressing it down firmly to create a smooth, gap-free shape.
I used molds made especially for creating sugar eggs. The 6-inch mold cost $4.00 and the four-inch version was $2.25, but you can create your own molds with dollar-store plastic eggs or other shapes you find.
Scrape a straight edge across the top of the mold to even it out. Place a cookie sheet on top of your open mold top and flip it over quickly to release the sugar egg half onto the cookie sheet. It should pop out easily.
Dry the egg:
The halves can be left to air dry for an hour or two, or bake them at about 200 degrees for 20 minutes. This time can vary depending on the size of your mold and the wetness of the sugar, you're looking for a hard outer crust and a soft, scoop-able center to the egg halves.
Step 4: Carve the Egg
When you take your egg halves out of the oven, you'll have a hard shell on the outside of the egg, but the inside will still be soft sugar. Carefully tap through the sugar crust on the flat side of the eggs and scoop out the soft sugar inside until it's 1/2 to 1/4 inch thick. (Choose the thickness based on the sturdiness of your egg.)
This process is similar to hollowing out a pumpkin for carving, just scrape a spoon gently around the interior of the egg. Most of the time, the soft sugar will fall right out. Sometimes, you'll hit a drier spot which will require a little careful whittling with your knife.
Carve the window:
Using the tip of a small blade (a paring knife or pocket knife), carefully poke out the center of one egg half and carve an oval-shaped hole. This will be the window into the egg's interior.
Let your egg dry again in the 200-degree oven for an hour, or on a counter overnight. The egg will become much harder -- like ceramic -- and easier to handle. This makes it much more difficult to carve, so make sure you've finished your shaping first. (If you need to make some major changes after the second drying, a Dremel tool is a handy secret weapon.)
Step 5: Decorate and Fuse the Halves
Now we'll need a batch of royal icing. Combine one pound of powdered sugar with 1/4 cup of meringue powder (available at craft stores) in a mixing bowl. Add 1/2 cup of warm water a little bit at a time and use a hand or stand mixer to combine. For our purposes, we're looking for a thick royal icing which will maintain shapes and dry quickly. It will hold stiff peaks in the bowl.
Decorate the inside of the egg:
If you're going to create a scene inside your egg, work on it while your egg is in two pieces. The world is your oyster when it comes to decorating. Colored royal icing can be set into any shape (For more complex shapes, pipe the item onto a practice surface, let it dry, then anchor it into the egg with wet icing). Coconut shreds dyed green look just like grass. Marshmallows snipped with scissors naturally make rabbit ear shapes, and the sticky exposed interior holds pink sugar for ear-like coloring.
In my version, I created a hollow egg filled with jelly beans into which I set a printed bunny, so I fused two empty halves. You can also "glue" a piece of fabric or felt into the egg for a unique treat box. (Photos of those versions in the final step.)
Fuse the egg halves:
Using a piping bag or a sandwich bag with the tip snipped off, pipe a generous line of royal icing around the edge of one egg half. Place the second half on top and line them up to match. Icing may squeeze out of the edge. Simply wipe it off with your finger or a paper towel. This seam will be covered, so don't worry about the line.
If you don't have a piping bag set, you can use that trusty sandwich bag, or simply buy the fancy tips for a piping set for about a dollar each at a craft store. Set the tip into your snipped bag and you get all of the same patterns for a fraction of the cost.
And now it's time for our familiar refrain. Say it with me... "Let it dry!" Royal icing will dry very hard if given a little time. We're already starting with a stiff mixture, so you might be ready to move on in just a few minutes. A damp paper towel or plastic wrap on the surface of your royal icing bowl will keep the remaining icing from drying out.
Step 6: Decorate the Outside and Fill
Pipe a few practice lines to test which patterns will look good as well as cover the seam around the egg. I used an up-and-over motion for this piping, but stars, dots, and straight lines will work too. Any errors can be wiped off the egg and redone while the icing is wet.
Pipe one large line around the main seam and a smaller decorative line around the "window."
Decorate the exterior:
You now have a basic egg which can be dressed up in many ways. I chose stars with yellow sugar pearls set into them. Use whatever you have around to add color and texture... sanding sugar, dragees, candies, etc. A young child might like their name piped onto the egg, while an adult may enjoy a motif personal to their interests, like music notes.
If you did not create a scene inside the egg, you can choose to fill it with treats instead. This version is filled with jelly beans and a printed bunny cutout. Chocolates, jelly beans, pastel M&Ms, or even silk flowers set into dry oasis would work as a gift or centerpiece. I know a certain teenager who wouldn't turn down an iTunes gift card tucked into a homemade sugar egg...
The finished egg does not need refrigeration, but it should be kept dry. Sugar and royal icing don't spoil easily, so wrapped in plastic, the egg should keep indefinitely. I kept a plastic-wrapped sugar egg saved for two decades!
