  1. Heat oven to 180C/160C fan/gas 4. Butter and line a 30 x 20cm traybake tin with baking parchment. Measure all the sponge ingredients into a mixing bowl and mix together using an electric hand whisk until smooth. Spoon into the tin and level the surface.

  2. Bake for 25-30 mins until lightly golden and the top of the cake springs back when pressed with your finger, and the sides of the sponge are shrinking away from the sides of the tin. Carefully lift the sponge out of the tin, then transfer to a wire rack to cool. Remove the baking parchment.

  3. To make the icing, tip the butter into a bowl and whisk using an electric hand whisk until light and fluffy. Add half the icing sugar and whisk again until incorporated. Add the remaining sugar and whisk again until smooth. Spread the icing over the top of the cold cake.

  4. To decorate, place a double row of raspberries across the centre and down the length of the cake to make a cross. Next, place a single row diagonally from each corner to the middle. Now fill in the empty spaces with blueberries. Cut into squares to serve.

Have made this for a friends birthday and it looks lovely although not as "flag-like" as your picture - mainly because the berries I've got are a bit big so the lines are less defined. Anyway it looks a bobby dazzler so I hope it tastes as good. (By the way, it's dairy free in my version - just substituted soya marg and plain Alpro yoghurt where necessary and you really can't tell the difference).

Lovely recipe, made this for my mum's birthday but used normal full fat yogurt instead of greek and it worked perfectly. I found the butter icing a bit sickly so I would use cream cheese or quark if I ever made this again. I also obviously didn't make my mum a flag cake and just arranged the fruit in a pretty pattern.
(on a side note, the comment about the 'smelly family gathering' by robynkirsty is very very funny...I have been rocking in silent laughter in front of my screen for the past few minutes!)

Have made this sponge a couple of times in the recommended size tin with perfect results. Can anyone please recommend how to adapt the recipe to fit a traybake tin 38 cms x 25 cms?

Oops meant to say small not smelly !!!!

I would like to do this in a square tin to feed only 8 (smelly family gathering). Can anyone suggest how much to reduce the quantities. Going to cover it with white chocolate buttercream, sprinkles etc for my daughters birthday .

I did that cake a couple of weeks ago. The sponge is delicious and it looks stunning!

I made this sponge base for my daughters eighteenth birthday party to great acclaim. I didn't have yoghurt so replaced that with cream and buttermilk which worked fine. I doubled the mixture to create two cakes to sandwich together with strawberry jam and buttercream and then iced with buttercream. Really moist and delicious.

I love this cake!, it's one of my favorites!! I even do it with 2% fat Greek yogurt! Does anyone know if I can use Soya yogurt (Alpro) instead of the Greek yogurt?

Made this for a Jubilee Afternoon tea Party. I made it well in advance and froze it. Thawing it was no problem, the cake stayed deliciously moist. Looked absolutely stunning as a the centre piece for the table!

Our club had Basque visitors for the weekend. I made 4 and sandwiched 2 together with home made black current jelly making 2 cakes each spread with whipped cream and decorated with fruit to resemble the Basque and the GB flags. Very easy, moist and light. Went down a treat.

I've made this with my 8 year old son twice and each time has been a great success! He loves putting on all the berries and now wants to do the Scottish flag with brambles!!! Tastes lovely too.

Perfect for the jubilee, the kids loved decorating it. I increased the amounts of everything to make a larger cake and it was delicious. I think next time i'd make two layers and sandwich them together.

Tried this cake out....turned out great the whole family enjoyed it!
Ate it all at one go..... mind you we were about 14 for dinner!

A really easy recipe that went down beautifully for the jubilee. I increased the amounts and used a larger tin so increased the cooking time by a few minutes.
The children loved decorating with the fruit and to make it look extra special iced the slides and edged those with half strawberries. Definitely one to repeat for special occasions, the Olympics and the George cross for Euro 2012 could work too.

I will keep the recipe for this easy sponge, very simple to make and failproof in my eyes, but the mix was quite liquid, so only good for leak-free baking tins!

FAB cake - easy to make and ice, decoration looked amazing and tasted great. A winner all round. Still moist 4 days later after being kept covered in the fridge.

I baked this for our street party and it went down a treat! everyone commented on how lovely it looked and it tasted amazing. I doubled the recipe as i had a bigger tin and covered the sides with butter icing as well, mainly to cover some imperfections!
