A four-layer passionfruit martini cake with passionfruit martini soaked vanilla sponges, passionfruit curd, and much more! 

Ohhh HELLO THERE passionfruit martini cake! The place have you ever been all of my life?! Genuinely, far too excited to share this cake as I’m fully obsessed and in love with it – and also you guys have demanded the recipe for ages now, SO HERE IT IS! 

I’ve wished to make a bake like this for as long as a passionfruit martini is by far one in every of my favorite cocktails on the market and in cake kind?! Oh, my precise days!! My passionfruit martini cupcakes all the time go down nicely once I share them, so this cake goes to blow your thoughts! 

Passionfruit Martini

So whether or not you name it a passionfruit martini or a p**nstar martini (which do have slight variations), they’re each scrumptious. Usually entails vodka, passionfruit liqueur, and prosecco in case you go down the p**nstar route. It’s in all probability one of the crucial well-liked cocktails on the market, and I’m blissful to confess that I like it!

I really like something passionfruit flavoured, it’s simply so good! I wished to get that flavour throughout on this bake, so I used a mix of passionfruit liqueur and prosecco to make my flavouring to get just a little little bit of deliciousness throughout – I didn’t really feel the necessity for the vodka on this event as I actually wished to passionfruit to return by. 

I made a syrup by mixing collectively the liqueur, prosecco and caster sugar. I simmered this and stirred to dissolve the sugar, after which boiled the syrup down till it was diminished by over half, thicker and robust in flavour. That is used to soak the sponges barely, and in addition flavour the frosting. 


As I used to be making a four-layer 8″ cake, I went for a 500g mixture of cake. This often means I weigh medium-sized eggs for weight – and match the remainder of the substances. Plenty of individuals are very opinionated on whether or not that you must truly do that, and no you don’t – however if you’re anxious, or simply need the perfect outcomes, it’s one of the best ways of getting them. 

I often beat unsalted butter or baking unfold with the sugar first to get it good and creamy. Then, I add in my flour and I usually use 9-10 medium eggs for a cake this dimension (sure I do know, it’s big, nevertheless it’s meant to be!). Combine this all in, and add some vanilla extract in case you fancy! Passionfruit martinis do are likely to have vanilla in, so it really works. 

Cut up the cake combine between two 8″ cake tins like these ones, and bake on a decrease and slower bake. Due to the scale of the sponges, and also you wish to get two layers out of every, they’re deep. The decrease and slower technique means a softer and extra scrumptious sponge with a extra even bake! 

As soon as the desserts have baked and cooled, layer them, after which drizzle on the syrup. Let that scrumptious syrup soak in, and you’ll then embellish!


The frosting on this cake is an American buttercream-style frosting due to the steadiness it offers. It’s a easy mixture of BLOCK UNSALTED BUTTER, no spreads of margarine right here, after which icing sugar. The ratio utilized in that is 1:2 of butter:sugar so that you’ve stability of flavour, but in addition it offers a sturdier buttercream which is so essential once you wish to cowl a cake in it! 

To color the frosting I used just a little peach meals colouring as a result of it gave it extra of a passionfruit colouring, but in addition I used the remainder of the passionfruit and prosecco syrup I had made to provide a candy flavour to the frosting. 

Different sorts of ornament contain making two-tone buttercream which you’ll be able to 100% do in order for you, however I liked how this turned out because it was! The color is simply so fairly and ideal. 


If you find yourself adorning a cake like this its a lot better to make use of a turntable, an angled palette knife, and a giant steel scraper to get the appropriate finish outcome. The method of smoothing the buttercream across the cake utilizing the palette knife, and ending it off with a metals scraper will get probably the most stunning end. 

As a result of the frosting is a stunning peach color I wished to distinction with a white chocolate drip, and I’m so glad I did! The color distinction is what makes it look just a little extra Passionfruit Martini like, and in addition I so simply love a drip cake as you all know. White chocolate drips are additionally tremendous straightforward with 3:1 chocolate to cream. 

I whitened my white chocolate drip utilizing some white meals colouring as white chocolate ganache is of course fairly yellow, simply to take the sting off. That is clearly elective, and it doesn’t change the style in any way. 

I used leftover buttercream to pipe onto the cake with my favorite piping tip as all the time. I discover randomly piping like I’ve on this cake usually appears actually spectacular and creates a showstopper as soon as topped with sprinkles and different ornament just like the passionfruit segments.
