Cake Sugar Designs has some way nifty technology which lets you come up with personalized cupcake designs which they print out using edible "ink" and mail to you. Then you just peel off the edible designs and lay them on your cupcakes. Sweet! And, well, sweet!
What would make any birthday cake experience even more fun? Digging for dinosaurs while you eat it! Instructables member mikeasaurus (of course) came up with this awesome idea and shares step-by-step instructions.
When I was in Japan I learned about this new kind of crafting clay called "paper clay" or "fuwa fuwa clay." It comes in kits from which you make adorable miniature desserts. The clay is unbelievably light and pliable (the term "fuwa fuwa" means light and fluffy). It air dries overnight so no baking it in an oven like with polymer clay.
