  4. Store in a zip-lock bag at room temperature. Fondant will keep for months in a zip-lock bag. To use again, reheat and knead well until stretchy before each use. You can add color as desired but for dark colors, you should add them during the mixing process or you could get a sticky mess.

Recipe Notes

Skill level: Newb
One of the most important parts of making any sculpted cake with a 'smooth' look, marshmallow fondant can also be quite the burden. There are many things that can go wrong with fondant, including:

  • Fondant tastes terrible
  • It can tear and wrinkle, making "elephant skin" on an otherwise smooth surface
  • It's expensive!
  • It's time-intensive to make and time = money

One of the first things I focused on when started as a cake decorator was fondant. I think Wilton fondant was the first product I used and I quickly became familiar with working hard on a cake, only to have the fondant get elephant skin, or rip and tear, making the process of having to re-roll out the fondant, cover the cake, have it rip... agh!

I began experimenting with ways that I could extend marshmallow fondant with the store-bought brand to create something that was cheap, easy to make and great to work with.

The total cost to make 4.25 lbs of LMF fondant costs about $5, all the while working just like the good stuff that costs an arm and a leg.

I have used small batches of LMF during cake tastings to convince brides and clients that fondant can taste good. I hope this recipe helps you in your cake decorating career as it has in my own.
