Reddit mentions of Kracie Popin Cookin DIY Cake Shop Ice Cream Cone Frosting Desserts (Cake Mix)

That one is original, but does everyone realize that you can buy Japanese kits that let you do this kind of thing yourself? These are toy kits that make edible candy that looks like teeny-tiny versions of various foods:

• Hamburgers with fries & soda
  
  
• Pizzas with soda
  
  
• Donuts, but different from the video and without the Krispy Kreme box
  
  
• Sushi bento box, including extremely realistic-looking fake salmon roe
  
  
• "Ice cream" cones, with the ice cream being made out of frosting
  
  
• Similarly, here's an eBay auction with 12 different kits. My wife did the bento kit with the panda-shaped "rice" ball on the bottom row, and she loved it.

What makes me happy is making and finishing a craft, their is something magical about making something with your own two hands with raw material.
