So many other tutorials we've seen give you printable number templates to use, but her methods are a huge improvement.
No printing, cutting, then cutting again, then peeling paper off a tacky cake. No printable template at all. Instead, So Yummy offers simple visual cutting diagrams showing you exactly where to cut your cake, then how to assemble each piece into the shape of each number.
You'll also find a ton of inspiration for wildly creative decorating ideas on the site that even an amateur could DIY at home. I'm a bit obsessed with the 8-year-old race track cake with Hot Wheels shown above, and I absolutely love the idea for a garden-themed #5 cake, complete with gummy worms.
And, of course, the #4 unicorn cake is sure to be a favorite since unicorn themed parties show no sign of disappearing any time soon.
