Picture of Chocolate Space Invaders
Show off your love for things retro and geeky with an edible armada of space invaders. This instructable will take you through the steps of making a simple chocolate candy using a silicon mold.

For Xmas last year, my better half surprised me with a spunky turquoise ice tray produced by ironic home goods designer FRED, inspired by the Taito arcade classic that we know and love. Space Invaders! After the novelty and enjoyment of freezing water, juices, coffee, and regular old liquids wore off, I set my sites on putting this gift to a higher purpose.


That's right, after a few test runs and brushing up on some elementary chocolate making theory, I was able to pull off in time for V-day the perfect display of geek love - a chocolate 8-bit sprite.

Step 1: Tools and Ingredients

Picture of Tools and Ingredients
The Mold
First and foremost, one needs to acquire a mold. I opted to use the Ice Invaders ice tray, but really any flexible silicone mold/tray could be used to shape chocolates. You could even use a clear plastic candy mold, but in my opinion silicone are more durable and easier to work with.

If you do plan on going the space invader route, you could try to find one locally or online. We bought ours in Japan, but I have seen them available on Amazon or at ThinkGeek (naturally). The downside of these is that they are on the small side so if you're going to make lots of chocolates you might need to pick up more than one to speed things along (there are 24 molds in each tray). Moreover, they don't match the original Space Invaders sprite to the pixel, but they do get the point across rather well.

And if you're wondering, I'm not affiliated with either site above or the manufacturer, FRED. I do appreciate the sense of humor they bring to their product design though, and consider this a quality product.

The Ingredients
1) Chocolate - For this 'ible I went with a Japanese dark chocolate that was available, but any type will work. Milk, Dark, White - go with your personal preference. Remember, better quality chocolates will make for a better tasting Space Invader.
Pictured are two 58 gram chocolate bars (roughly 2oz each). To fill the entire mold I would recommend at least 3 bars of chocolate, and if you're making solid chocolates possibly 4 (8oz or 232 g)

2)Filling - For the sake of simplicity I went with solid dry ingredients: almonds and dried blueberries.
If you were to use a creme filling, caramel, cordial, or a truffle ganache it would require a bit of a different method (painting a shell and so on). Since this is my first attempt at confectionery, I thought the Invaders would be too fragile to hold up that well as a shell. I decided to stick with fillings that will provide a strong structural center. Blending in flavourings such as vanilla, sea salt, and chili pepper work well too. Get creative and adventurous.

The Tools
Here you have plenty of freedom to improvise, but this is what I had to work with:
1) Cutting board (flexible is a plus)
2) Sharp kitchen knife
3) Silicone spatula (rubber is fine too)
4) Squeeze bottle (thinner spout the better) - alternatively you can use a pastry bag.
5) Stirrer (I used some disposable chopsticks)
6) Microwave (or double boiler) & microwave safe bowl (ceramic is a plus as it retains heat well)
*If you have one on hand, an electric kitchen thermometer is helpful, but not really necessary.

Now that you have all of the items assembled, go find a cool dry space in your kitchen to get to work.

where did you get your ice tray
depends on where your from, being a kiwi i got mine from Hallenstiens.

I actually got this from the LOFT store in Kobe, Japan about a year ago. If you're in the US or Canada, the manufacturers website has a list of online and brick-and-mortar sellers (http://www.worldwidefred.com/storefinder.htm)

I see their stuff in the oddest little shops, so you can just keep an eye out for them. Shop owners may be able to special order it for you too.
you can get them on thinkgeek's website

Made these for my girlfriend as a Christmas present. It went awesomely. I'm seriously impressed with them!

I've also created a little custom made box to put them in (12 chocolates in total). The template of it can be found here:


For the brits reading this I got the ice tray off of amazon.co.uk and used Tesco's own chocolate from their baking aisle. Pack with a melty middle muffin on the front. It work perfectly, no blooming, melted easy and it tastes pretty good ;)

Thanks again!

Try grating the chocolate with a cheese grater
AwajiMan (author)  benduy4 years ago
That is a fantastic idea! I've never tried that before.
A very cheap double boiler.

sauce pot filled about 3/4 to half full of water + stainless steel mixing bowl set inside the sauce pot.

Heat it up so the water is just under a boil.

add the chocolate & watch it melt.

I have been able to get chocolate down to a good liquid and it wont burn.

Thanks for writing this; and for pointing out the potential problems. (seized chocolate and missing antennae) I liked the link to the science of tempering chocolate.

I thought this would be how to make the mold, this being Instructables...

I don't mean to be negative, but is this really an instructable?
I thought this would go into how the mold was formed... Not simple "melt the chocolate and pour into molds" directions.

Still, nice idea when most people would have just used this for ice-cubes.
Still, only an idea with directions, not really an instructable.
This is still an instructable, because it teaches people to do something.
The mold was bought, so he probably has no idea how it was made.
I think its an awesome idea.
Isn't the definition of an instructable giving instructions so that someone else is able to make or do something? This instructable provides the idea of using one item for something else (an ice-tray for a candy mold), a way to melt chocolate (instead of using a double boiler set up), and a little bit of science (Step 3). To me, this is a well thought out and well documented instructable.

Hey! Thanks for this instructable, I just finished my own little chocolate invaders :) Had no trouble finding the mold at amazon.de (Germany).

If you want to have a look: http://bit.ly/t4thAe (it was a present).

If I had space invaders-tray, I bet I would make sound effects while eating them :D

Hey, I got a silicone heart-shaped icecube-tray, I guess I should make these not later than valentines next year. Great 'ible, I like the informative photos.

Nice Job! :)
Here in Brazil it's impossible find geek mold like this ... :(
My vote is yours!
They can be ordered easily enough online.

$7.49 for the product, plus $30.04 for shipping fees.

Okay, it can be easily ordered online, but not cheaply. Actually, very very very expensive.
Yeah, ThinkGeek have some crippling postage charges for posting outside the US. :(

 Sorry about that, I guess that one of the downsides of this 'ible is that it uses a proprietary product.

It'd be possible to make your own mold. There are some excellent instructables on molding gummies from legos and making cornstarch candy molds. I would think that the concepts would transfer well to chocolate molding, and the plus side of the lego method is that you could make a true pixel sprite of a Taito space invader.

Yeah, lol, when you mentioned the silicon mold I assumed you had somehow made one, meaning you must be a real xenophile to go to that length.

brilliant i am making these for my birthday :) thanx
A double boiler can be duplicated by filling a small saucepan with water, and then sitting a metal bowl on top. Heat the water, pour your chocolate into the dry bowl on top, voila, double boiler action. Gives you a touch more control over the process, and allows you to keep stirring throughout. If you're having trouble with the microwave method, you might give this a go.

This is awesome! I wish they included the towers you fire from (in the mold), as that would be a nice addition to the final display. Good job, Awajiman.
AwajiMan (author)  thecapper5 years ago
 Thanks capper. Yeah, I was a little disappointed that there wasn't one of those in the mold (although the box it came in has it printed on the
I think I've seen these molds in New Zealand which is odd cause we normally have a fairly limited range of... well everything. I might have to make some of these.
Thanks very much!
Great instructable!
a wish has came true!!!

Oh this is just awesome! 
I have that same mold, bought from here, UK site - http://www.red5.co.uk/Ice_Invaders.aspx

I never thought of filling them with chocolate, time to give it a go!!

I couldn't help be a little disappointed in the invaders mold because they're of course not allowed to use the original authentic character shapes without royalties - they don't actually match the game characters except in pixellated goodness, but then if they did match, the ice cubes wont stay in one piece anyway - diagonal pixels you see!
Still, close enough.

Excellent 'ible, many thanks!

Space Invaders? They look like the Moononites from Aqua Teen Hunger Force.
The Moononites were modeled after space invaders.
