Ingredients

  • 100 g (3.5oz) raw kale leaves, woody stalks discarded
  • 150 g (5.3oz) unsalted butter, softened
  • 150 g (5.3oz) granulated sugar
  • 2 eggs
  • 2 tsp vanilla extract
  • 1 orange, zest and juice
  • 200 g (7.1oz) plain flour
  • 1 tsp baking powder
  • 0.5 tsp salt
  • 75 g (2.6oz) unsalted butter, softened
  • 250 g (8.8oz) powdered icing sugar
  • 2 tbsp orange juice, possibly a little more

Method

  • Preheat oven to 170C/325F.
  • Line or grease a muffin tray.
  • Tear the kale leaves into bite-sized pieces and boil or steam for a few minutes until tender.
  • Refresh in cold water, drain and puree (it will still be a bit stringy).
  • Set aside.
  • In a large bowl, cream together the butter and sugar until light and fluffy.
  • Beat in the eggs, one at a time, and then beat in the kale, vanilla, zest and orange juice.
  • Sift in the flour, baking powder and salt and stir to gently combine.
  • Fill the muffin cups 3/4 full and bake for 15-20 minutes or until an inserted skewer comes out clean.
  • Allow to cool in the tins for 10 minutes, then remove to cool completely on a wire rack.
  • For the icing: In a large bowl, cream the butter until fluffy.
  • Sift in the icing sugar and beat until thick.
  • Add enough orange juice to make it a frosting consistency.
  • Once the cupcakes have cooled, spread the icing across them.
