Ingredients

For the cake

  • 300 g unsalted butter, softened
  • 300 g white caster sugar
  • 6 medium free-range eggs, beaten
  • 300 g self-raising white flour
  • 1 tsp vanilla extract
  • 150 g raspberries

For the topping

  • 200 g unsalted butter
  • 450 g icing sugar
  • 1 tbsp whole milk
  • strawberries
  • blueberries
  • raspberries

Instructions

1
Preheat the oven to 180°C/Gas Mark 4. Grease a 30x25cm (12x10in) tin and line with baking paper.
2
Place the butter in a large mixing bowl and add the sugar. Beat together with an electric mixer until the mixture is light and fluffy. Add the eggs one at a time, adding a spoonful of the flour if the mixture starts curdling.
3
Fold in the remaining flour with a metal spoon until you have a soft, smooth cake mix.
4
Stir in the vanilla extract, then carefully fold in the raspberries. Spoon the mixture into the cake tin and bake for 25-35 minutes until golden and risen. Since this cake is long and wide, make sure you check the cake is cooked through by inserting a skewer in the middle of the cake until it comes out clean.
5
Cool in the tin, then transfer onto a cooling rack and leave to cool completely.
6
For the topping, beat together the 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.
7
Add a little milk and beat the mixture until creamy and smooth. Spread the butter icing over the top and sides of the cake.
8
Find a picture of the Union Jack flag and recreate the pattern using a selection of sliced strawberries, blueberries and raspberries, leaving the white buttercream exposed to create a white line.
