Hi all, I am new to this and have a question.

I am making a wizard of oz cake for a birthday which is tomorrow... I want to make a rainbow to stand on top of the cake, but how do I get it to stand up if it is just made from sugar paste? I do not have any gum paste and will not be able to get any in time. I have some edible glue - could I mix that with icing sugar to make a gum paste? I have no idea if that would work!??

I thought about sticking a few cocktail sticks in the bottom to stick in to the cake but I fear it will fall over. Also considering rolling each colour of 'rope' around a wire which I can then bend, but not sure if it would be too heavy and just fall over.... nightmare!

Many thanks for any suggestions, its all a bit last minute this cake, my niece only decided what she wanted last night!

Many Thanks cakey-doodles

The only way to make fondant hard enough to stand up is to use either Gum Paste or add some Tylose Powder to your fondant. Adding edible glue will not harden the fondant.


You can insert tooth picks inside the bottom of the rainbow to help it stand or you can use candy melts to "glue" lollipop sticks behind it.

I can't say if the ropes with wire in them will work or not. I've never done that. To me it seems like the ropes (without adding tylose or using gum paste) would be too soft & heavy & the wire would eventually cut through the fondant.


If I were making a rainbow I would use either gum paste or fondant w/tylose. You can do it several ways...

1. Roll different colored ropes & glue them together to make a rainbow. Add candy/lollipop sticks to back once the rainbow has dried.

2. Roll out a flat, white piece of fondant or gum paste, cut out the shape, then using edible markers draw on the different colors.

3. Do the same step as number 2, except attach the ropes to the flat piece OR you can cut out flat, skinny strips of fondant & attach to the base

4. You could also make the rainbow out of candy melts or royal icing. Let it dry hard then attach a lollipop stick to the back with candy melts.

I just made one the other day. I used pastillage which dries so hard you can sand it.  Here is the cake. I used broken in half, (lengthwise), popsicle sticks to support it.

I suppose I didn't see you post in time for pastillage to dry, but for future reference...

Hi Jan

I didn't have any pastillage {I actually didn't know it existed til I started reading about it here]. I wouldn't have had time to get some anyway since it was all very last minute! Anyhoo, I finished the cake late last night, not really happy with it since I had several glitches and I was pretty much rushing and without a proper plan of what I was going to do and what it would look like. But I guess it is ok for a last minute job and hopefully will be exciting for a 5-year-old's eyes! I will post a pic...

Thanks again ladies, I look forward to more sharing here :)
