I had to put my foot down and tell him he wasn't getting a 3 tiered cake (but the fact that he requested it makes me feel like I'm raising him right!). In the end I passed on all the typical Google and Pinterest examples out there that had exploding beakers and oozing test tubes (that I wasn't sure I could pull off....) and decided to make the cake look just like the invitation, which we both loved.
One thing I had planned from the start was that the top would be covered in the universal symbol for radioactivity, since it was so simple to recreate. For the rest I just enlarged the images of the beakers from the invitation and used them as a template to cut them out of fondant with an X-acto knife. Then I used the wrong end of an icing decorating tip to cut out all the circles for the molecules.
In the end, it wasn't my best fondant work at all, but I do love how striking and graphic it is. The microscope has to be my favorite! And to let you in on a little secret, the only reason the 7 is really there is because I ran out of beakers and still had this huge gap, and it was easier to grab a cookie cutter and make a 7 than trace out another beaker. Shhhhh!
Joseph seemed fairly content that the cake met all his expectations.
Half chocolate, half vanilla, as requested. The addition of Martha Stewart's somewhat salty "Rich Chocolate Frosting" (with 3 sticks of butter and a pound and a half of semisweet chocolate) definitely took it up a notch. The birthday boy gave it 2 thumbs up!
