Cakes 2 and 3-ish, Day 3

Since I didn't really make a cake on the day before my birthday, I decided I would make two today. Which I kind of did.... I split a sponge cake batter into 2 cake tins :) However, it was a bit of a disaster cake. I've never made a good sponge, and despite borrowing a beatermix for the occasion, it was still a big mess.
First mistake: overcooking the sponge. It seemed so soft in the oven.... but I think it was meant to be...
Second mistake: lazy/bad icing. The pictures say it all.

It didn't even taste that great - it was all dry and chewy. Anyhow, I'll put the recipe up. It's from Jo Seagar's "All Things Nice" cookbook (which is basically a massive ad for Chelsea Sugar).

Sponge Cake

4 large eggs, separated (room temp)
3/4 cup sugar (Chelsea, of course)
3/4 cup cornflour (I had to do half regular flour and half custard powder, since I didn't have any cornflour)
2 Tb custard powder
3 tsp baking powder

Preheat oven to 180 C. Grease two 23cm cake tins, line with baking paper.
Beat egg whites until stiff, then slowly add the sugar and beat until stiff and glossy.
Add the yolks one at a time, and mix each in well.
In a separate bowl, sift together the cornflour, custard powder and baking powder.
Gently fold the dry ingredients into the egg mixture, using a metal spoon (not sure why).
Pour half mixture into each tin and bake for 15-20 mins without opening the oven door.
When cooked, the cakes should  shrink slightly from the sides of the tins, and spring back when touched gently.
Cool for 10 mins in the tin, then turn onto a wire rack covered with a teatowel, so the rack doesn't leave an imprint on the cakes.

Jo suggests serving with whipped cream and strawberries, but I ended up icing mine. I wanted a typewriter cake. It was meant to be red.... but turned out pink. So I wrote "HAPPY METHDAY BROSE" on the pebbles/buttons, and tried to draw a meth pipe... which ended up looking too phallic, so Lauren fixed it by turning it into a massive purply smudge. Here are the pics... it looks... cute? In a kind of messy and amateurish way...

Maybe I'll have more success with my next cake...
