Picture of Rainbow Marzipan Cake
Kids and adults, we both like good looking and tasting cake.
And what could be cooler then a good tasting marzipan cake with an included rainbow?

This is a reciep i came up with about 17 months ago, to my own birthday.
I since then enhanced it, until even i ate it. (i'm usually not into cakes...)

It not only looks really cool and tastes good, it also wont dry out as fast as a normal cake would.
I published the reciepe a year ago on my blog and on my board (in german), and i thought that this has to be on instructables.

Step 1: Ingredients and Tools

The ingredients list, usually the most important thing.

I am only used to the metrical system, but for your convenience i used a converting table, to also give you imperial measurements. But maybee you still wanna check that yourself.
I hope Cups are allright? If not, tell me.

If your confused with something, look at the pictures.


375g flour (3 & 3/4 Cups)
250g sugar (1 & 1/2 Cups)
250ml Oil (1/4 quart) dont use oliveoil or any other oil with taste
200g powdered sugar (2 Cups)
200g marzipan (1 Cup )
125ml water (1/10 Quart)
5 eggs
2 packages of vanilla sugar
1/2 package backing powder
Food Dye, 4 would be nice.
Powdered Nutmeg
Powdered Cinamon
Powdered Anise
Artificial rum flavor (so its kids compatible)
Butter (less then a hand full)

4 Bowls (yeah really)
26cm (10 & 1/4 inches) springform pan
4 Spoons
1 Teaspoon

This is *very* similar to what they call "Gypsy Cake" in East Anglia; it's a cake that bakeries make as a treat once a week, out of the pieces of leftover cake mix from all the other cakes that they make, so it's somewhat randomly multicoloured. Gypsy Cake also contains marzipan - the similarities can't be a coincidence? By the way, marzipan turns out to be surprisingly easy to make yourself, with equal quantities of almond flour (or just ground almonds) and icing sugar, and an egg white to bind it.

Great Recipe, made one of my own last night and it looks brilliant

Instead of using sugar icing, can I use chocolate icing? Will it work with the taste of the cake? I just love this recipe and want to try it for a friend's birthday, but she loves chocolate (and marzipan) but not sure if it works together??

My friend and I make rainbow cake all the time, generally with just a boxed mix, and we've never actually spent the time is put it in all nice and precise. That looks really cool.

Made the cake as my friends wedding cake, she loved it. Will try and dig out a picture of the cake. It was not a hippie wedding but still quite strange by Irish wedding standards. 
 I also made it for work for the shops i work in's 4th birthday, the staff loved it but customers thought we were trying to make them eat coloured soap. (I work in a soap shop which sells soap that looks edible)

For at least some colors there are natural alternatives, such as turmeric for yellow, a red one that I can't remember at the moment, and I'll bet that if you soaked dried blueberries in enough water to soften, then mashed them you'd get a decent purple or blue dye. 

(Beautiful instructable, Wupme, thanks!

Im making the wedding cake at my friends wedding in 2 weeks. gonna try this one!!!! Its caketastic!!!!!!!

hmmm, only make it black and white. Weddings are formal unless ur a hippie.
Looks great for a regular style cake batter...there is also a recipe out there for a tie dye cheesecake with a red velvet crust/bottom (just search it) and it comes out awesome. Made it once for a staff picnic and people went crazy over it! Thanks for sharing!
You said you published this in german on your blog. Could you please send me a link to this blog? I'd really appreciate this. :D

Could this work for a pre-mixed cake? Or does the Marzipan have something to do with it not mixing too much? (did that make sense????) :-) This looks outrageous!
wupme (author)  JakiO6 years ago
You can use a premixed cake for it if you want. At least i don't see a reason why it shouldn't work. You can mix as much as you like, the thing is just that the marzipan always will leave small "pieces" of itself in the dough, no matter how hard you mix. I just mentioned it so you don't worry about those Marzipan pieces, because they are ok. So pretty much nothing to worry about, except that cops are gonna pull you over if they see that cake on the backseat i guess....

Cool! I'm going to try it for my friend's birthday next August 2th *_* Looks so tasty *_* it's a piece of art **
maniuni6 years ago
i will definitely try this!
Hi, When You say package, how much is this? I'm in Blighty you see! Would love this cake to by my daughters birthday cake. Thanks
wupme (author)  MissSmurfsnot6 years ago
Hmm let me think. 1/2 Package Backing Powder is a flat teaspoon (5gramms) 2 Packages Vanilla Sugar (can be the cheap artificial one) are 2 heaped teaspoons (so about 20gramm, you don't gotta be to precise on that one, 3 heaped teaspoons are fine too).

Looks great. (would be an exclamation point by my keyboard is having problems) Any chance you could do a marzipan Instructable? I love marzipan.
wupme (author)  Ferrite6 years ago
You know what, maybee i can do that next month. (don't got any extra money left for this one) One ingridient for good marzipan aint that easy to find. Rose Water. At least in Germany, the only place i can think of would be a pharmacy. If ii can get some, you get a marzipan instructable. But be warned, the x-ray scanner on the airport sometimes can't differ marzipan from c4 ;) (no joke)

Here in Holland I found rose water in Chinese or Indian "toko's", Shops where they also sell all kinds of Asian food, and the little china trinkets (incense holders, mortar&pesles, kitschy cat statues and cheapo daggers etc.)
Surely there are some of those shops on that side of the border _
Here every town has a few (at least that's what I found)
wupme (author)  Blue Rose6 years ago
Thanks, i never thought about looking at a chinese or indian store. Its true, they use it pretty common for sweet several dishes, sometimes i ask myself where my mind is.... But i'm not shure if we got one? I knew we had one, but the last time i've been there is about 8 Years ago. The city where i live is poor when it comes to other cultures, except for turkish stuff. Well if not, there is still the internet where you can get really everything :)
Blue Rose wupme6 years ago
Good Luck finding it then _

Which city do you live in if I may ask?
wupme (author)  Blue Rose6 years ago
Ludwigshafen am Rhein, near Heidelberg.
Ferrite wupme6 years ago
That would be great! I've never heard of Rose Water before except in books, never seen it in a store either, good luck finding it! The security will probably let you thought with it if you give them some : - )
