DIY Giant Cupcakes!

Uncover a land of Giant Cupcakes, fairy dust, and butterfly kisses with this adorably sweet treat of a DIY project!

What you’ll need

  • Expansion Spray foam
  • 12″ planter pot, round plastic trash can, or plastic bucket
  • heavy duty cardboard
  • Red spray paint (or any color of your choice for the “cupcake wrapper”
  • White spray paint
  • Red Christmas ornament (for the cherry)
  • Glitter, colored beads, or metallic confetti

A few things to note:  The expansion foam is very messy. Wear disposable gloves and follow the directions on the can.  Hint…Shake is for at least a full minute!  Use it slowly, and don’t try to rearrange it or touch the foam, it’ll get everywhere.  So be deliberate with your placement.  You can practice with the bottom layer since most of that will be covered.

This can is also a kind-of one-time use thing.  (click here to see how you can extend the life of your can), so plan on making two cupcakes.  Use 1/2 of the can on the first layer of each cupcake.  That should use up one whole can.   After 45 minutes to an hour later, use your second can for the top pyramid layer of the two cupcakes.

The foam takes a couple of hours to fully expand and 24 hours to fully cure.  You may think you have frosting that melted, but it will grow, just give it time.  And if you’re not happy, add a little more.

Time to paint

The expansion foam has a yellow hue to it.  I chose to paint it white. Pink or blue frosting would be fun, too.  Cover and protect the area outside of the foam from overspray – You only want the “frosting” to be painted.

Now Decorate!

Add glitter, small beads, sequins, or confetti to your cupcake.  Any craft embellishment will work.  Use waterproof glue or Mod Podge to hold it in place. Design any fantasy cupcake your imagination can dream up!
