Picture of Making the perfect Portal cake!
Have you ever wanted to make the cake from Portal, but don't care for any of the recipes out there? I have found a solution!  Whether it's a treat for yourself, or, like me, you have friends that love portal as much as you do (and are in need of a birthday cake), this is a delicious, customizable recipe for the perfect Portal cake. :]

NOTE: This was my first attempt at a portal cake, and it went quite well!  I'm a complete amateur when it comes to baking, so anyone should be able to make this cake without a problem.

Step 1: Gather your materials!

Picture of Gather your materials!
This recipe made a White Cake with Coconut Filling and Chocolate Frosting on the outside.  But, as I mentioned, it can be customized to whatever you prefer.  For example, the coconut filling can be replaced with any filling you want (or just frosting!), as it's not going to show until the cake is cut.  As for the Chocolate Frosting on the outside, you can easily make whatever flavor you want and just combine some dark food coloring to it.  Your chocolate shavings are going to cover and hide most of the icing!

For this cake will need the following:

- 1 Generic Cake Mix (Any box will do.  Baking from scratch is also an option. Doesn't matter!)
- 7 Ounces of Cream Cheese (cold)
- 7 Ounces of Butter (room temperature)
- 1 Teaspoon of Vanilla Extract
- 3 Cups of Powdered Sugar
- 1 Cup of Shredded Coconut (sweetened)
- 4 Ounces of Bittersweet Baking Chocolate
- 1 Tube of White Decor Icing
- 4 Ounces of Semi-Sweet Baking Chocolate (chocolate shavings will work too, if you can find them.)
- 8 Maraschino Cherries (no stems!)
- 1 Solid White Candle (longer than average is better)

Now, this recipe could be doubled very easily.  My cake was only going to feed two people, so it ended up being quite small (with a lot of icing leftover!).  But there is enough icing in this recipe that to double it all you need is a second box of cake mix and a second tube of white decor icing. ^_^

Me and my fiancee are soo going to make this! he got me into the game and at first i was afriad of the cake, but then i knew that we had to make it! thanks for the recipe! we will definatly be posting pics!

Lol. The cake isn't scary! ^_^

My result: instead of cherries we used strawberries (because of allergies), and instead of the decor icing we used whipped cream. Very nice Instructable and it tastes delicious!

P.S. A pity that the recipe did not include fish shaped candies !

I'm posting this to reddit, too. :D
Thank you very much for the help, without this receipt we wouldn't have been able to make this.

And with receipt I mean Recipe. ^^
bettinasusca (author)  M.Black2 years ago
Ahh, awesome! Looks great. ^_^ ...I *might* have to make another one this year for my boyfriend's birthday. It was so much fun. :]

Glad it worked out!

Alright, I will be baking this cake (with help from an other friend) for a friend of mine who's celebrating his birthday this week. I DO have a question though, is it absolutely necessary to use "Baking chocolate" instead of normal chocolate? Because I don't see the difference.
Thank you for helping us help you help us all.
Will post results in a while.
bettinasusca (author)  M.Black2 years ago
I don't *think* it would make a difference. Possibly the texture of the shavings, but why not try it? ^_^

I'm excited to see the results!
I made the cake for my Dad's birthday, it was tasty. Thank you for making this!

Why did I picture a bundt cake with blue or orange decoration before I clicked on this? Nice work.
bettinasusca (author)  tireswing3 years ago
hahah. Well, blue and orange are the colors of the Portal portals, so... maybe that? As for the bundt cake, I have no idea. rofl

Thank you!!
Yay! That sounds excellent, too - what with the coconut and all. :D
bettinasusca (author)  jessyratfink3 years ago
Agreed! The coconut is what made it for Jesse (birthday subject in photos).

Personally, the all the cream cheese icing is what does it for me. lol
