On to phase 2!

  • Prepare your choice of frosting (here, whipped cream).
  • Again, taking a golf-ball sized dollop of frosting, carefully spread it on top of the cake with a spatula.
  • Work slowly and add more as you need it, moving on to the sides after you finish the top.
  • If you're using whipped cream like I am, put the cake in freezer for about 5 min after the interior is completely coated as a safeguard against meltdown.
  • Don't worry about smoothing the surface, because the exterior of the cake in the game has a very rough surface. Convenient, no?
  • To match the color of the cake, you can add food coloring to a batch of white frosting, or in my case, add chocolate shavings to mimic the texture and tone of the surface (they'll stick to the whipped cream and completely cover any traces of white on the surface. The recipe in the game suggests using one can of "prepared coconut pecan frosting", if you can come by that.
I don't know if you can buy chocolate shavings, but in a pinch, small milk chocolate chips work too.

  • I went at squares of baking chocolate with a knife, but box graters work too.
  • Then I took the shavings and applied them to the coated surface of the cake with a spatula, making sure the board the cake was resting on aluminum foil to catch stray shavings. Press gently to minimize the white appearance of the cream.

When I made a Portal cake for my boyfriend's birthday, I avoided the fish-shaped ethyl benzene, but did try to stay true to the in-game recipe whenever possible. So for the frosting, I took a bag of shredded coconut and mixed it with canned chocolate frosting. It was a bit hard to spread, but gave a nice texture and was very tasty :)

I thought that baker's chocolate was unsweetened, and would therefore be too bitter to be used as a confection. Maybe the whipped cream underneath helps sweeten it?
