Gin and Tonic Traybake!

A Delicious and Delectable Gin and Tonic Traybake Cake with Gin and Tonic Drizzled Sponge and Gin Infused Buttercream Frosting!

It’s been a while Gin… I have missed you. I’m sorry it’s been over a year since my latest Gin recipe, but I am back and here to party. Not really, but either way it’s damn delicious because hello Gin. 

If you don’t like Gin, then this post isn’t for you… obviously. However, Gin and Tonics are still on the rise and I am taking it whilst I can – who wouldn’t want it in cake form?! And before you say ‘what a waste of gin’.. you can have a drink on the side and then have double the Gin!

I personally love Gin, and so does my fiancé, but I get that some people don’t like the Tonic side of things. I used to struggle with Tonic as I’ve never been the biggest fizzy drink fan, and some tonics can have a slightly weird taste. However, in the cake? It’s delicious. 

This beauty of a cake is a combination of my Gin & Tonic Drizzle Cake and my Gin & Tonic layer cake. Both of them are delicious, but I know you all love my recent addition to my blog of more traybake cakes. 

Traybake cakes are so much easier to serve at parties, you only need one tin, and you don’t need to decorate it in any particularly fancy way. Bake the sponge, slather on some frosting, and you are done! I just add lime zest and sprinkles to make it look pretty.

The actual sponge is just a regular Victoria sponge in a way, but with lime zest added in, and then the drizzle on top. You can’t use a really soft sponge with this recipe, because once you have added the drizzle on top it’ll be really soft like a lemon drizzle cake is.

The drizzle itself is easy… gin, tonic, and sugar. The sugar is important because it’ll help make it into a syrup which will soak into the cake far better than just tonic and gin – and best thing is you can choose which flavour or type of Gin and Tonic you use!

I have so many Gins at home I just pick whichever I fancy when I make a cake, but I wouldn’t worry too much about using a coloured gin as it won’t come through very strongly at all. The flavour will, the colour won’t as it’ll be diluted and poured onto a beige coloured cake. 

Instead of using a buttercream frosting like I have in this, you can easily use a water icing type decoration such as in my Gin & Tonic Drizzle Cake post. I know not everyone is a fan of buttercream frostings, and my young childhood memories are of watery icing… with a gin kick though they’re amazing. 

I really recommend using a 9×13″ Traybake Tin for this recipe because it’s the best traybake size around. I use a 9×9″ square tin for my brownies, cookie bars, and such like… but this is a traybake cake. Whenever I see them in the supermarket they are larger and deliciously sized. 

For all your summer parties or celebrations, this one is for you! Obviously, it’s not kid friendly.. but that just means there’s more for the adults! Enjoy!

    1. HI Jane, I can confirm that it worked successfully substituting the tonic for lemonade! If anything it was sweeter, but I reduced the sugar in the cake by almost half which was also a success. Thanks for another great recipe :)!
