My boyfriend has been requesting a colourful cake for a long time, so I let him design this one and he helped make it. I have to say I was a little dubious of the colour scheme he chose but I think it turned out pretty cool in the end! It makes me think of a foreign planet, or something from a Dr. Seuss book. The decorations were once again inspired by Katherine Sabbath‘s cakes.
We baked a lemon cake from Annie’s Eats for the layers, which was a good standard almost pound cake-like cake. It might have been a little fluffier if I had used cake flour as the recipe requested, but I never buy cake flour since it always seems to be bleached. I have heard you can substitute a small amount of corn starch in if you use all-purpose flour, which basically reduces the gluten content to make the cake a little lighter – maybe I’ll try that next time.
I made my usual swiss meringue buttercream recipe (6 egg whites worth was pretty much perfect for filling and frosting the cake with a bit left over for piping). I added some crushed freeze-dried raspberries, vanilla extract, and purple food colouring to the frosting for between the layers. I added lemon extract and blue food colouring to the frosting for the outside. I prefer the lemon buttercream I made another time by adding lemon curd – the lemon extract almost tastes like fake lemon candy to me. But it was definitely easier!
For the decorations, we made stripey meringues, sugar glass, and added some orange rope-y candies that I found at the candy store. I used the same striping technique as for the last meringues I made, but mixed a bit of orange food colouring into the meringue itself so there would be less contrast with the stripes. I also added orange extract instead of orange zest, and used the recipe from Sweetapolita. Following this recipe, the meringues dried out completely, which I prefer to the last ones, which were still chewy on the inside.
I used this recipe for the sugar glass (but I made only a half recipe, and added liquid orange food colouring). It turned out very neat, and didn’t take long to harden at all! I accidentally let it heat up to about 350 degrees, but it was still fine.
Here’s a view of the purple on the inside of the cake:
