ZERO Calorie Cupcakes

I recently made three dozen "ZERO" calorie cupcakes to pass out to some friends and acquaintances recently. Don't they look yummy! Would you believe they have ZERO calories? Its true!!!! "How can that be," you ask? uh.... because they are not edible ;-) LOL I crack myself up.... 
I used an insulating foam to create the cupcakes. This 16 ounce spray can of insulating foam I picked up at Home Depot was under five dollars. It made a LOT of cupcakes.

I only filled the cupcake liners half way... you can see in this photo below how much the Styrofoam rises with the 24 hours that I let them set up.

I ended up having to cut off the tops down to become "cupcake" size. If your going to try making some, I would recommend filling them only 1/4 high in the cupcake liners. It will look like a squiggly mess when you first spray it in the liners, but when it rises, it will be a perfectly smooth.
I also had to cut off the bottom of each cupcake as the Styrofoam created a round bottom to each cupcake making them wobble when set down. For the frosting I used "Patch-n-Paint" lightweight spackle. I used pink paint in this cup below. The first photo shows the cupcakes that I mixed straight red paint into the white spackle thinking it would turn pink... it didn't, it looks more like a salmon. Whatever~
I noticed too that some of the frosting had started to crack. I think this might have happened due to the spackle being old and having sat in the garage for over a year. If I were to make more of these, I would invest in new spackle. But for what I used them for--- it was perfect. Perfectly funny that is *wink*
Here are a couple of tips if your wanting to try making some.
  • Again, only fill each cupcake liner 1/4 the way up.
  • Don't touch the foam with your hands--- that's some sticky stuff!
  • Once you start spraying the insulating foam you have to either use it all up or toss it as it won't let you use it over several days.
  • Use a piece of double sided sticky tape to hold your cupcake liners in a cupcake pan. The foam will make it expand right out of the cupcake pan leaving you with a "hot mess." 
  • If your needing to wash off any tools, do it outside with a hose and not down your pipes. 
  • Make sure you tell your "dumb" friends that they cannot eat them. *wink* 
big hugs,


  1. Really neat! Love the zero calories! :) Linda

  2. They do look real! LOL
    That foam is wild. It grows huge!:(

  3. These are pretty darned cute!

    OK, a true story. When I turned 18 my mom made my birthday cake a two-layer, frosted deal. Out of styrofoam. The hips started at an early age... Thanks for reminding me of that good memory!

  4. cute! I always use plaster of paris for my bases. but I think your idea for the base is definitely cheaper!
    leave it to Cheryl to always have a good idea!
    have a great day

  5. Dangit - I thought my prayers had been answered! lol
