How to Make Marbled Fondant Icing for Cakes

Updated on June 16, 2017

Easy Steps to Creating a Beautiful Marble Cake Finish

Sometimes a plain cake covering just won't create the effect that you need. For my latest cake project, a Christening cake with a froggy theme, I needed to make the cake look like a pond for the frog. The frog also needed lily pads to sit on.

I decided to try out a marbling technique that I'd read about many times before, and the results were very pleasing to say the least!

Although it was my first attempt and experimental, I decided to take pictures of the process and share them with you here in this step-by-step guide to marbling fondant icing.


  • Equal amounts of ready-to-roll, coloured fondant
  • Icing sugar
  • Rolling pin
  • Sharp knife
  • Cake ready to ice!

Step 1: Prepare the Coloured Fondant Icing

Take a quantity of fondant icing ready coloured to your required shade.

Tip: If you require a large quantity of icing it may be easier to buy some ready coloured. You can also colour it yourself. I use paste food colours and knead them into the white fondant icing, adding more until I reach my desired shade.

Make sure you have equal quantities of coloured and white icing.

Tip: You can use two different colours instead of white if you prefer

Knead both colours into pliable balls so that they are ready to work with.

Step 2: Roll the Fondant Balls into Sausages

Take each chunk of fondant and use your hands to roll in into sausage strips

TIP: You can vary the thickness of the strips to make the marbling effect more or less

Lay the sausage strips alongside each other, ready for the next step

Step 3: Twist the Coloured Sausages Together

Take hold of the strips on one edge and gently roll them together as shown in the picture

This will twist the colours together, creating an alternating colour pattern

Step 4: Roll the Sausages Together

Gently roll the strips together, kneading it slightly to encourage the strips to bond together

TIP: Take care not to press too hard or you will lose the marbling effect

Step 5: Fold the Sausage Over

Slightly flatten the combined sausage strip and fold over one more time, ready to start to form into its shape for rolling out

Step 6: Shape the Sausage into a Round

Prepare to roll out the fondant by shaping it into a round, like you would do with pastry.

Tip: It doesn't need to be perfectly round here as you will achieve a better shape once you start to roll it out

Step 7: Roll Out the Coloured Fondant

Roll out the mixed coloured fondant in the usual way to finalise the marbling effect.

TIP: Turn the fondant over to place it on the cake, the marbling will be more defined than the side you have just rolled out

Step 8: Cover the Cake

Cover the cake in the usual way...

Lift carefully, using a rolling pin if necessary and gently lower over the cake

Smooth the fondant using an icing smoother

Trim away any excess fondant and re-smooth

      Good information. I never thought about doing my own marbled fondant for a cake. I might just have to try it next year for my daughter's birthday. She loves this kind of thing.

      Thank you so much for the tips. I've never used fondant, but have been thinking of trying it. This is a beautifully done lens with great step-by-step photos.
