I decided to have the transformer look like he was bursting out of the cake somewhat like the Elmo cake I did last year (you can see that cake here). I mostly decided on this design so I could avoid having to make legs...I was really worried about how I was going to make a transformer at all so the less I had to make the better, but it all went together really well.
I planned to cover this cake in fondant...marshmallow fondant. The first time I made MMF was a disaster, but over a year later I was willing to try it again. I prepared the MMF the day before so it could sit in the refrigerator overnight per the instructions on the recipe I was using (I detailed the making of the fondant in my post yesterday).
I cut an Autobot and a Decepticon out of fondant (store bought) and also cut out 'Happy Birthday Jaydon' in a Transformers font. I planned to paint these with silver luster dust.
Before I could cover the cake, I had to color the fondant. I decided to use blue and really wish I had heeded the advice in one of the recipe reviews and colored the marshmallows right after I melted them, but I didn't know how much fondant I would use to cover the cake and didn't want to get stuck with a lot of leftover blue MMF. It was definitely a workout kneading the color evenly into the fondant.
The fondant went on the cake almost perfectly. I had a few wrinkles toward the bottom in what ended up being the back of the cake, but I was pleased especially since it had been a long time since I covered a cake in fondant. I gave myself some bonus points as well, since it was 6 in the morning and I had not had a full cup of coffee yet.
The cake was chocolate with mint filling and chocolate buttercream. I am not a huge lover of mint, but after I set some aside for a dessert I was making later that day, my kids and I were fighting over who got to eat the leftover filling. I will share the recipe tomorrow when I post about my Mint Julep Brownie Bites.
