Faux Sure! The Foolproof Way to Marble Fondant

Roll, twist, bend, squish! Marbling fondant is actually pretty fun, and kinda easy. There's really only one rule to remember: the more you work the fondant, the more finely marbled it will be.

I've created a classic marble look for my cake, but you can use the same technique to make a marbled galaxy, smooth marbled fondant stones or even a marbled swimming pool. Be creative and play with the proportions, or use more than two colors: It's all good.


  • Crumb-coated cake
  • Black fondant
  • White fondant
  • Fondant rolling pin
  • Small knife

Step 1

Portion enough black and white fondant to cover your cake.

To find out how much you'll need, check out this chart from Satin Ice: How Much Fondant . For a lighter marble I used 2/3 white to 1/3 black.

Step 2

Roll the white and black fondant into long ropes, equal in length. Slice the white rope in half and lay a piece on either side of the black rope. 

Step 3

Twist the ropes together and give them a gentle squeeze so they stick. 

Step 4

Roll the twisted ropes, so they come together even more. Fold in half. 

Step 5

Use the palm of your hand to smear the twist flat. 

Step 6

You could definitely stop here if you want a chunkier kind of marble. If that's the case, just get busy rolling out your fondant and covering your cake. But for an even more sophisticated look, keep going. 

Step 7

Roll, twist and fold the smeared fondant rope, exactly as you did before.

See the magic starting to happen?

Step 8

Squish the fondant down a little with the palm of your hand to get it started, then roll it out flat and carry on with your cake.

We call that stone cold spectacular.
