Method

  1. Heat the oven to 180°C (fan oven 160°C, gas mark 4). Grease a 30 x 25cm tin and line with baking paper.
  2. Place 300g butter in a large mixing bowl and add the sugar. Beat together with an electric mixer until the mixture is light and fluffy.
  3. Add the eggs one at a time, adding a spoonful of the flour if the mixture starts curdling.
  4. Fold in the remaining flour until you have a soft, smooth cake mix.
  5. Stir in the vanilla extract. Carefully fold in the raspberries.
  6. Spoon the mixture into the cake tin and bake for 25-35 minutes until golden and risen. Check the cake is cooked through by inserting a skewer in the middle of the cake and when it is ready it should come out clean.
  7. Cool in the tin and then transfer onto a cooling rack and leave to cool completely.
  8. For the topping, beat together 200g butter and a quarter of the icing sugar in a large bowl until soft. Add the remaining icing a little at a time and beat until smooth.
  9. Add a little milk and beat the mixture until creamy and smooth. Spread the butter icing over the top and sides of the cake.
  10. Find a picture of the Union Jack flag and recreate the pattern using a selection of blueberries and raspberries. Enjoy!
