Funfetti Traybake

Why make a simple school style traybake when you can make a Funfetti Traybake? Super simple to make and a huge hit with kids. If you don’t want to add the sprinkles into the cake, leave it out and you will still have a delicious cake. Serve it with hot custard or if you want to make it more indulging, top it with buttercream instead.

I use a 9×11 inches cake tin.



  • 225g margarine
  • 225g caster sugar
  • 4 eggs
  • 300g self raising flour
  • 1 tsp baking powder
  • 1 tsp vanilla extract
  • 100g sprinkles

To decorate

  • 150ml icing sugar
  • Warm water as needed
  • Sprinkles


Cream the margarine and sugar together till light and creamy.

Add the eggs, one at a time. Add a couple of spoonfuls of flour to stop the mix from curdling.

Once all the eggs have been added, add the rest of the flour, followed by the vanilla extract and the sprinkles.

Pour the cake into a greased and floured tin and bake in a pre heated oven for 30-35 minutes on 170c till the cake is fully baked.

Once baked, let the cake rest in the tin for a few minutes before turning it out on a wire rack and cooling it completely.

To make the icing, mix the icing sugar with warm water till it is smooth. Use more or less water depending on the consistency of icing you prefer (if you prefer a thicker layer of icing, then add more icing sugar). Spread the icing onto the cake and quickly add the sprinkles before the icing starts to harden up.
