Star Wars Cake (Mustafar)





Introduction: Star Wars Cake (Mustafar)

About: "Better to have it and not need it than to need it and not have it."

In a town far, far away. A dad decided to make a Star Wars cake for his son's birthday.

Step 1: Bake the Cake, and Make Rice Crispy Treats

Step 2: Cut a Hole in the Rice Crispy Treat Hill and Add a Ramekin(cup).

Step 3: Coat the Rice Crispy Hill in Chocolate.

Make sure you spread the chocolate to make a flat area of land. You'll see what I mean in a minute.

You will also need to pull out the ramekin before you do this step.

With a sharp knife, cut jagged pieces of "land" right at the "shoreline" of the rice crispy hill. You can heat the knife to make it cut better.

Step 4: Test Fit the Rice Crispy Hill on the Cake.

My cake was a little small, so I had to slice it horizontally, and open it up like a book.

Test fit the pieces and trim to fit.

Remember where all the pieces went. Use a digital camera for this step.

Step 5: Frost the Cake.

I used super day-glo orange for the frosting. I used an off the shelf Pilsbury brand white frosting with a liberal amount of orange food color gel.

Top the cake with the hill and the jagged pieces of "land".

I microwaved a little of the frosting for 10 seconds so it was slightly warm and pourable. I poured it around the area of the ramekin opening, and let it dribble down the side of the hill.

Step 6: Make the Sides, and Added Effects.

I got the leftover chocolate and re-melted it in the microwave, I poured it over some non-stick surfaces (you can use waxpaper) into a large, flat, shape. Once cool, cut into strips the the height cake. cut the strips to match the jagged pices of land and use frosting to stick it to the cake.

Melt more chocolate and "weld" the top and side pieces together.

For the platform that R2-D2 is standing on, get a sour cream container lid, or any lid with some structural relief (little plastic ribs in the structure for interest). Lightly butter, or spray some non-stick cooking spray, inside the lids. Use these as moulds for melted white chocolate.

As an added bonus, I got some blinking lights from the cake decorating section at Walmart. These are supposed to be attached to the stems of Champagne glasses, etc. I made a couple of moulds out of a measuring spoon, and the center of an apple slicer/corer. I buttered them well and poured more white chocolate in them. Once they started cooling down I insterted the blinking lights in the white chocolate. Once completely cooled down I popped them out of the molds and used them on the cake.

Step 7: Special Effects/After Effects

The ramekin, which I'm sure you have guessed by now, is for dry ice and water.

I'm sure you're kid will enjoy this.

Sniff, sniff!

ok, I feel a little silly asking this as I was looking through the comments as no one else asked that I could see so it's obviously an obvious answer. I get that you melted chocolate, but what type of chocolate did you use? Btw, thank you for taking the time to post this tutorial :)

That's funny. I could have sworn that info was in there somewhere but after a quick search I see that it isn't. I think it was just the regular melting chocolate that look like discs, but any melting chocolate that hardens back up when cool will do.

I want one

I'm pretty sure the picture is what used to be a cake. But I'm just guessing here.

I went with a Lego Ninjago theme, but same cake. Thanks for the instructions!! it was a big hit.

Loved this idea. I used it for a Lego Ninjago design. My son wanted a Lego cake, and I saw this and thought it'd be perfect.

I am going to try to make this cake, so I am not sure if I am happy you posted it very ticked bc I did not read the instructions before today, and I am making the cake for my son's b-day!!! I am not creative, but he fell in love with the idea, wish me luck!

You'll do fine! Besides this site is all about inspiration. There is no need to duplicate, or try to duplicate, someone's efforts 100%. Just do it and have fun with it.

Check out all the other images and comments below from others who have opted to make this cake. Every one of them is unique, and they all came out will yours.

Awesome! It's so cool that this instructable has had some longevity.

I would just like to say, you need a lot of chocolate for this step. Or I did it wrong :)

Do or do not....there is no "wrong"! - Yoda ;) The Rice Crispy hill is coated in the melted chocolate, so there really isn't that much there. The rest of the cake (if I remember right) only had 1/4" thick chocolate layer. meh - who doesn't like chocolate? Right? Enjoy!

I ended up using 4 7oz tubs of the chocolate. But I made a double cake. Man my kids loved it. What an awesome cake. And, I couldn't find a R2D2 so Yoda was on the ramekin :)

What happened to the ca..........Noooooooooooooooo!!! =P

OMG!!! this is so super duper awesome!!! you are a super dad in my book!!!

I am going to make your cake for my grandson, can't thank you enough for sharing this. I need the lights you used, I will go to Walmart cake section for them. What do I ask for? Are they used just for cakes or for other decorating idea. I think that was such a great idea you had. Thanks again, Grandma Sandy
