I really enjoyed making this cake, I’ve neglected my baking recently for all sorts of kitchen/boiler related reasons. Regardless of the situation, I have decided to bake on! That is what Mary would do, and don’t we all want to do as Mary does? I digress.
I whipped up a vanilla sponge with a classic 8,8,8 oz (sugar, self raising flour, butter) to 4 egg ratio and bunged it in the oven at 180C until risen, golden and cooked in the middle. I mixed up enough buttercream to sink a kayak, divided it up and coloured it in varying shades of blue. If you whip your buttercream lots and lots until it goes pale (before colouring it), you will achieve a smoother, paler buttercream.
The key to any good decoration is a cool cake. Once cooled, I cut it in half and layered lots of raspberry jam on one half of the cake and blackcurrant jam on the other (it’s good to mix things up every once in a while). I spread buttercream thinly on top of the jam and sandwiched the cakes together.
The coloured buttercream was carefully spooned into three piping bags. I like to put the piping bag in a mug and then fill it up- stops the bag falling all over the place. It is best to avoid buttercream splodges around the top of the bag as it will go all over your hands very quickly once you start squeezing !
To make a neat pattern I piped sausages of colour around the edges of the cake, alternating when it felt right to do so. The tricky bit is to use a spreader and blend it together to get very straight, smooth sides. I can always feel my heart beating LOUDLY when I approach any cake with a spreader (it’s very distracting). The remaining buttercream is used to make a swirly pattern on top to finish. I spent an awful lot of time touching it up, it’s hard to say when to stop phaffing. After all that, best not to keep it near a radiator as it will make you cry when all that smoothing and swirling melts everywhere.
This cake is dedicated to Kate who is due to have a baby boy very soon. 😀 🤰
