Everyone needs a few more sunshines and rainbows in their life right now. With the 3rd lockdown in full swing in the U.K. why not set aside some time to re-create this cute modern rainbow! It’s perfect to nestle on top of cupcakes or add to the sides of drip cakes. Plus you can change it up to match your style. Swap or add colours like a sweet lilac or a bright yellow. You can even change the gold splatter / pattern to hand painted hearts or use star sprinkles. For this cute little fondant rainbow tutorial read on.

1 Firstly, take your modelling paste / gum paste / fondant and roll it out into a rope shape. You can do this by just using an icing smoother tool to roll it back and forth. This will create a much more even look rather than using your hands. It’s also so much quicker and avoids any heat from your hands softening your work.
In terms of thickness we rolled out rainbow colours out to around 4mm. For smaller sizes you’ll need to make thinner rainbow sections. For larger designs try going to a thickness of approximately 1cm.
Note: If you’re creating a cool fondant rainbow that will need to stand up on top of a cake then you’ll need to make this in advance so that it has time to set. You’ll also need to think of the structure inside a little more and how it will fasten onto a cake. Utilising food safe wooden sticks such as brand new kebab skewers or cocktail sticks.

2 Next, use a piping tip to map out your rainbow. Take the first rope of modelling paste / gum paste / fondant and ‘fit’ it around the piping tip. Using your blade tool cut away the ends. For larger rainbows make sure to test using larger items like a circle cookie cutter to use as a guide. For tiny rainbows a thinner piping tip should work great!
3 For our rainbow we wanted the first section to be an on-trend gold colour. You can choose a different metallic or go for another cool colour to make your rainbow unique. This is pretty handy if you want your modern rainbow to fit in with different party themes. For Easter add in a touch of yellow or attach flower sprinkles! If you’re creating more beach vibe rainbows try out neon food colouring!
4 Add a tiny amount of edible glue along the top edge of your rainbow section. Then roll out another rope and attach it to your first section.
This layer of our rainbow is decorated with cool gold edible paint splatters. This is an effect we LOVE. It’s quick, easy and it’s looks so modern too. Just get some edible metallic paint and a food safe brush and flick it onto your work.
Idea: You can change up the design and hand paint leopard print, hearts etc on this section of your rainbow. Why not even texture it by piping royal icing pearls on top!

5 Now roll out another colour. We went for a bubblegum pink. Paint a tiny amount of edible glue along the top of your previous rainbow layer and attach the pink in place. Cut away the ends with your blade tool.
6 Finally repeat the last step but with any other colours you’d like to add and build your rainbow up!
Now you’ll have bright edible rainbows ready to dress up all your treats with. We added ours to some super cute cupcakes. You can make multiple and make a repeat pattern on the sides of a buttercream with yours. Why not add tiny clouds, rainbow sprinkles and a fondant sun on top for a super sweet idea? Whatever you do and however you make them one of a kind… have fun!
