Happy St Patrick’s Day Cake

irish green cake recipe

Happy St Patrick’s Day – Have some cake! (and possibly some Guinness to wash it down with!)How will you be celebrating or do you not bother? I’ll be going to a cookery demonstration tonight with WI pals and maybe persuaded to pop into a local pub afterwards.

I made this cake yesterday and there’s still plenty left. Its not a particularly irish recipe in that its a vanilla sponge cake but I have given a nod to the Emerald Isle with green frosting and a sprinkle shamrock on the top.

Doesn’t stop it tasting gorgeous though and somehow it seems to last longer than other vanilla cakes. I swore I would never share my vanilla cake recipes but quite honestly, its easier for me knowing where they are, when I need to make one. So go for your life …bake and enjoy!

Costello Vanilla Sponge Cake

Costello Vanilla Sponge Cake

Prep time 15 minutes
Cook time 40 minutes
Total time 55 minutes
Meal type Dessert, Snack
Misc Child Friendly, Freezable, Serve Cold
This is a big cake. You will get 3 good sized 8" cakes out of this mix. The recipe can be halved by using 4 medium egg whites.


  • 675g Caster Sugar
  • 225g Butter
  • 7 Egg Whites
  • 1 tablespoon Vanilla Extract
  • 500g Self Raising Flour
  • 350ml Milk


Using an electric mixer, cream together the sugar and butter until light and pale.
Add one egg white at a time, whilst mixing thoroughly. Keep scraping down the sides of the bowl.
Add the vanilla extract.
Alternately, add one tablespoon of flour and a decent splash of milk, whilst still mixing together on a slow speed,until all the ingredients have been added.
Scrape down the sides of the bowl one last time and turn the speed to high for approx 15 seconds. It will splatter and bubble so prepared!
Pour into 3 x 8" lined cake tins and cook at 180C for around 40-50 minutes or until a cake tester comes out clean. This is quite a flat mixture - it won't rise too much or give a big hump in the middle.

I am starting a new linky this week to replace Cake of the Week. A lot of my baking recently has been bread, biscuits and traybakes and I see some fantastic creations on blogs that I would love you to share.

The Bake of the Week linky will remain open until next Monday morning and I will post a roundup every Monday evening (starting 24th March). I will tweet anyone’s entries and also Pin them during the week. If you would be so kind to place the badge on any posts that you enter, that would be great. (Feel free to Grab the Bake of the Week badge to show that you take part if you like but not compulsory)

The only rule is that your Bake has to be from the previous week.

So Happy Baking!

      Nothing wrong with cake and coffee for breakfast, Jenny. Doesn’t everyone have that? We can pretend we are continental ๐Ÿ˜‰

      Hope he likes this one, Erin! I always think of this recipe as my ‘American’ sponge cake recipe though – no idea why, it just reminds me of American based desserts I’ve had.

    I keep seeing all these cooking things and think I should really give it another go…I might- but probably not! Looks gorgeous though. I will send on to my mum and then allow her to bake it for us! :-)

  5. says

    oooh now that looks delicious! We don’t celebrate St Patrick’s day but we do celebrate the fact that we became a couple on that day (13 years ago now!) and it was randomly at Pippa (Red Rose Mummy)’s other half’s birthday party!
