How To Make The Infamous School Dinner Cakes

One of my many cravings whilst being pregnant has been the infamous “school dinner cake”. You know, that delicious spongy cake with icing ands sprinkles. My face would always light up when I saw them in the dinner queue. After searching the shops and failing to find them, I concluded that I’d just have to make them myself which soon became a bit of an addiction as I’ve made four lots within two weeks. (I shared the majority of it, don’t worry). I’ve played around and put my own touch on it and thought I would share the ingredients and instructions with those of you that want to make this yummy cake.

I’ve made the instructions as detailed as possible with pictures and even a little video. 🙂


The ingredients amount that I’m sharing with you is to fill a regular size baking tray, (35w x 230dmm). 


  • 350g Self Raising Flour
  • 300g Caster Sugar
  • 350g Butter
  • 4 Eggs
  • 2 tsp Vanilla Essence
  • 300-400g Icing Sugar

Measure out and place all the ingredients, EXCEPT THE ICING SUGAR into one bowl.


  1. Grease the baking tray. I do this by spreading butter around the surface and sides of the tray. You then need to line the tray with baking paper.
  2. Pre-heat the oven to 170°. I have an electric oven. You may need it on 160° instead depending on which sort of oven you have.
  3. Beat together all of the ingredients in your bowl together (minus the icing sugar). This can be done using your hand, a bowl and wisk/hand mixer or if you’re lucky like me and have a grandmother with good baking equipment then you can use an electrical stand mixer. Beat the ingredients until it’s a smooth texture.
  4. Pour the mixture into your baking tray and smooth it out so the tray is completely covered.
  5. Place into the oven and wait for 35-40 minutes, checking occasionally towards the end. You can see if the cake is done by piercing a sharp knife into the middle of the cake. If the knife is wet when you pull it out then it’s not done. It’ll mean the inside of the cake is still soggy and needs a little longer in the oven.
  6. Once done, take the cake out of the oven and leave for 40-60 minutes to cool.


Once the cake is a cooler temperature, you can then do the icing. The icing for me is the trickiest bit. You don’t want it to be too runny because it will just drip to the sides of the tray and not cover the cakes properly (or very thick). This is my way of doing the icing. I’m in no way a cake expert, but I must admit it tastes nice every time. You’ll find that you use about 300-400g of icing sugar.

  1. Sift the icing sugar into a bowl. 
  2. Gentle place 1 tsp of water into the bowl and stir with a spoon. Continue…

You’ll probably use 2-3tsp of water in total to get a nice thick paste. My advice is to do the icing in two sections because you don’t want the icing to set too quickly as the sprinkles will simply roll off the cake. 


Leave the icing to set and then cut the cake into however many slices you want to get out of it. Lastly but most importantly is to ENJOY. x

I’m really not your average girl. I’m pretty random, pretty spontaneous. I’m fascinated with the universe, the planets, spiritualism, meditation, the law of attraction. I will always remember that one massive book in my nans ‘library’ room that was all about planets. I’d lose myself in it for hours! It’s mind-blowing how we are just one planet in a massive universe – but I’ll probably end up writing a separate blog post about this matter because I could go on and on. I love makeup but I love football more. I look like a girly girl but I’m a tomboy at heart. From a young age I’ve been brought up around football. Credit to my dad for that one who even took me to my first football match aged 8 months old at my home team, Portsmouth’s Fratton Park. I was surrounded by it constantly and just grew to love it and the way football is played. I’ve spent many of my days at Fratton park or stood on the side of a football pitch watching my little brother and dads football team play. Id consider myself creative – sometimes my overactive mind drives me crazy with little ideas. I have to write now to get a lot of it out. I’ll happily sit there for hours colouring fine detail pictures or just sketching. It’s really therapeutic if I’m honest. Sometimes I just want to become a hippy and not be apart of the outside world or be tied in with the government. Not saying I’m one for politics and I don’t really know enough about it to have much of a say on it but when I put things into perspective with the government and a lot of their rules, laws and “systems” it does really piss me off! I just want everyone to be chilled and loving lol but it’s an unrealistic want when I struggle to even get a smile back from the general public when I’m out. I know it’s easier said than done, especially when people are dealing with shit in their lives, but I think if everyone was a little more upbeat and open and commutated with each other, the world would be a much better place. I love music. All different kinds of music really, dependant on my mood.. like most people really. My favourite has to be reggae, techno, dnb & hip-hop. I grew up dancing to techno and hip hop music as I competed in freestyle disco and street dance. I think that’s one reason I love a rave so much. And as for reggae, I listened to that whilst in the womb. Bob Marley, like many, is my all-time favourite. I could sit and watch videos about him all day, especially interviews – I love his voice.
