This weekend I made a Cookie Monster cake for Jesse's 1st birthday. No problem - I knew exactly how I was going to make it and how I'd decorate it. What I didn't plan on (though I should have) was 80 degree temperatures in my kitchen Saturday night and Sunday. Made the frosting on Saturday night - (fortunately, the vanilla bean cakes were already made and tucked safely away in the freezer) and it immediately turned to blue soup (was too tired and cranky, or I would have taken step by step photos.)
It spent the night in the fridge, and I managed to get a crumb coat on the layers before the kitchen got too hot (was about 74 at the time). My first thought was to decorate the cake with the grass tip, which ends up looking like fur - similar to the elmo cupcakes and lion's mane. The frosting was WAY too melty at that point and turned into a blue blob on the cake, so I improvised and made peaks by pressing with my small offset. That worked great for the top, but when I tried pipe out frosting on the sides, it totally started sliding down. I moved into the living room and the finished the cake (cursing under and over my breath the whole time), and managed to spackel this together.
