How To Make The Spider Egg

To make our spider egg, start by slicing the domes off the tops of your chocolate cakes and make them nice and level. I torte my cakes in half so I have more buttercream stripes but it's not necessary. Use a 4" circle cutter to cut out the center of the cakes. Save the scraps in a bowl.

To make the base of the spider egg, cover the inside of a bowl with some plastic wrap. Pour in some melted chocolate to create a curved base. Chill it in the freezer until set and then take it out of the bowl and remove the plastic wrap. I glued my chocolate sphere down to my cake board with some more melted chocolate.

I colored some easy buttercream lime green and purple to match my sprinkles colors but you can use any colors you would like. When you're making deep colors like purple, you want to build your colors starting with a base. For example, if I just add purple to my buttercream it won't be very dark but if I start with pink, then add purple, it will have a much richer color.

Because food coloring is water based, it doesn't like to mix with my oil based buttercream. If you remove about ¼ cup of the buttercream and melt it in the microwave until it's just melted, not too hot and mix it back into the buttercream it will create an emulsion and cause the buttercream to darken in color.

Stack your cakes on top of the chocolate sphere and alternate with your colored buttercream. Fill the center of the cakes with your sprinkles mix and then cover the top of the cake with your cake clay to create the curved part of the "egg". Give the whole thing a crumb coat and let it chill.

Once your cake is chilled, you can give it a final coat of buttercream and make it really smooth and chill it once again.

How To Make A Gelatin Bubble Spider

Making this gelatin spider is super simple! I start with my some powdered gelatin. It's a 2:1 recipe. I do 2 Tablespoons water, then sprinkle on 1 Tablespoon gelatin and let it absorb into the water. Then I pour two more Tablespoons on top and add the last Tablespoon of gelatin. Let the gelatin bloom for 5 minutes then melt slowly in 15 second increments. Let cool slightly and scoop off the white foam and add some black food coloring. To make the bubble, I blow up a balloon but keep it very small. Tie the balloon in a knot to form the sphere. You only want it to be 3'-4" in size.

I tape a toothpick to the base of the balloon with some painters tape. I tend to use a lot of tape at the base to help support the balloon once it has gelatin on it. Coat the balloon in some vegetable shortening and let it dry for about it minute. Once the surface goes dull you can now roll the balloon around in the melted gelatin. I did two coats on my bubble so that it was a nice dark black. Let the gelatin dry for about 5 minutes between dipping.

Depending on how big your balloon is, you might find that the balloon won't dry upside down. If that's the case then you can just hang the balloon off to the side. There might be a drip on the underside of the balloon but you won't be able to see it once it's on the cake so don't worry about it too much.

Once the balloon has dried overnight, you can pull the balloon out slightly, pop the balloon and let it deflate and pull away from the gelatin. Pull out the balloon.

To seal the hole, melt down some chocolate and spoon a bit out onto some parchment paper or a silicone mat. Place the gelatin bubble on top and chill it until it hardens up. This bit of chocolate seals the hole in the bubble as well as providing a place to easily attach the gelatin bubble to the body of the spider.

To make the body of the spider, I take some of my cake scraps from the spider egg cake and combine it with some buttercream to make cake clay. I roll that clay into a ball and roll it into some black sprinkles. Then you add a little melted chocolate to the top and glue on your gelatin bubble.

Attach 8 pretzel legs to the body with some more melted chocolate and chill the whole thing for about 10 minutes to let it set up and get really firm.

Completing The Spider Egg Cake

Melt down your marshmallows until they are nice and smooth. You're going to want to wear some gloves for this part or you'll have some very sticky hands. Dip your hands into the marshmallows and stretch the marshmallows out between your fingers. Wrap the strands randomly around the cake to create the web look.

Once you're done adding webbing, attach cake pop stick to the base of your spider with some more melted chocolate and insert the spider onto the top of the cake. Dip some pretzel sticks into some melted chocolate and attach to the ends of the legs and arrange onto the cake so the spider looks like he's sitting on the egg.

I used a couple of green sprinkles for the eyes of the spider to finish off the look.

When you cut into the egg, the spider web sticks to your knife and creates a fun effect that my daughter thought was really entertaining. The sprinkles fall out of the inside of the cake like "eggs" and is pretty fun to see!
