Unicorn Woolworths mud cake hack

This Unicorn Woolworths mud cake hack is a quick and budget friendly way to make a birthday cake, without having to actually bake anything.


The majority of the time I love baking, but the lead up to a birthday party is not one of those times.  I decided for my daughters birthday party this year that I would skip the baking part of the birthday cake and instead focus on the decorating side.  I instead opted to use trusty Woolworths mud cakes in place of baking my own cakes.

Since my plan worked so well (I think so anyway), I thought I would share exactly how I put together this unicorn Woolworths mud cake hack.  First of all, I purchased 3 Woolworths mud cakes at $4.40 each.  Any flavour works, but I choose to go for all 3 flavours which included a dark chocolate, white chocolate and caramel.


To stick the 3 layers together as well as cover the top and outsides of the cakes I made a buttercream icing, but you skip this step and use a pre-made icing from the baking isle.  To make the icing I made a double batch of the buttercream I used in my Ice Cream Cone Cupcakes recipe.   You will need 500g butter, 4 cups of icing sugar, a few drops of vanilla extract and food colouring.


Soften the butter then add to a stand mixer along with the vanilla extract.  Beat the butter until it’s pale and creamy, which will take at least a few minutes depending on your mixer.  Next, gradually add the icing sugar while continuing to beat the butter.  Beat  until well combined and the mixture is light and fluffy.


The next step depends on how many colours you plan on using, but I divided the buttercream into 3 equal portions, the coloured each portion using food colouring gel.  For this particular cake I coloured 1 portion pink, 1 purple and 1 teal blue.  To assemble the cake, place a small amount of buttercream in the centre of a cake board, then place the first cake on the board.  Cover the top and sides of the first cake with the first portion of icing.  Repeat this step with the remaining 2 cakes and 2 portions of icing.


Once all 3 cakes are assembled, use a knife to gently blend the colours together.  Then, top with a whole heap of different lollies and lollypops.  I found my unicorn cake topper, rainbow candle,lollies and lollypops in Kmart, all for around $1 – $2 each.


All up this cake cost less than $20, tasted amazing and best of all took very little time, leaving more time for other party preparation.
