The ombre rose cake is quite simple to make once you get a hang on piping the rise swirl. You can use either the 1M or 2D Wilton tip. I prefer the 1M as it gives more defined swirls.
To create the rose swirl cake you will need:
1M tip
Piping bags
Buttercream
Cake, crumb coated in the colour you will use for the rose swirls.
To make the ombre colours, start by colouring 1/3 of the icing in the darkest shade you will be using. Then divide the coloured batch into 2, add yhe same quantity of uncoloured icing into the second batch to lighten it, divide and colour until you have all the shades.
Remember to colour enough as you may not be able to get the exact shade if you run out of a batch.
Next, fill you bag with the darkest colour and make the first layer of swirls. You may reverse the colour, starting with the lightest. You may also want to make lines on the cake to help you pipe equals swirls.
Continue piping the swirls until you cover the entire cake. If you have spaces, just fill them up with stars.
And you have your Ombre Rose Swirl Cake.
