  • Prep Time: 20 minutes
  • Cook Time: 40 minutes
  • Total Time: 1 hour
  • Yield: 12 cupcakes 1x


  • 175g butter, softened
  • 150g self-raising flour
  • 50g custard powder
  • 175g caster sugar
  • 1 tsp baking powder
  • 3 large, free range eggs
  • 1⁄2 tsp vanilla extract

For the compote:

  • 450g rhubarb, cut into chunks
  • 150g caster sugar
  • 150ml water
  • 1tsp vanilla extract

For the frosting:

  • 125g unsalted butter, softened
  • 250g icing sugar
  • 50g custard powder
  • 50ml milk


  1. For the compote place the rhubarb, sugar and water in a small saucepan and cook over a medium heat.  Simmer for around 20 minutes or until the compote is thick and smelling delicious, add the vanilla extract then remove from the heat.  Set aside while you make the cupcakes.
  2. Preheat the oven to 180°C and line a 12-hole muffin tin with cupcake cases.
  3. Place all of your cake ingredients into the bowl of an electric mixer and mix to combine.  Once all of the ingredients are blended together, using an ice cream scoop divide the mixture between the cupcake cases.
  4. Bake for 20 minutes or until the cakes are golden and spring back with touched.  Allow to cool in the tin for 5 minutes before turning out to finish cooling on a wire rack.
  5. When the cakes are cool cut a hollow out from the middle of each sponge, this is easiest with an apple corer, and fill with the rhubarb compote.
  6. To make the frosting place the butter, vanilla, custard powder, icing sugar and half of the milk into your electric mixer and mix to combine.  If your frosting is looking too stiff add a bit more milk until you reach a pipe-able consistency.
  7. Spoon the frosting into a piping bag fitted with an open star nozzle the pipe tall swirls of the icing on top of each cupcake. Top with a fondant flower or pink sprinkles to finish.
