Instructions

  • Preheat the oven to 180C (350F) and line a rectangular brownie tin with greaseproof paper, letting the paper hang over the sides.
  • Sift the flour, cocoa powder, malted milk powder, baking powder and bicarbonate of soda into the bowl of your stand mixer.
  • Add the sugar and mix on low speed to combine.
  • Combine the milk, oil, melted butter and vanilla in a measuring jug and gradually add to the dry ingredients while mixing on low speed.
  • Increase speed to maximum and whisk for 3-4 minutes until thoroughly combined.
  • Pour the batter into the prepared tin and tap on the counter so that the batter settles and any bubbles are released.
  • Bake for 35-40 minutes or until the cake is springy and coming away from the sides of the tin.
  • Lift the cake by the paper and leave to cool on a wire rack.
  • Make the frosting: put the icing sugar, butter, milk, cocoa powder and maca powder into the bowl of your stand mixer.
  • Start whisking on low speed to combine then increase the speed to maximum for 2 minutes.
  • Gradually add the melted chocolate and whisk until the frosting is glossy and thick.
  • Spread the frosting over the cake using a palette knife. Add mini eggs and sprinkles or your favourite decorations.
  • Slice into squares and serve!

Notes

To make the cake vegan, substitute the milk with soy or almond milk, the butter with a non-dairy spread and the malted milk powder with maca powder (or cocoa powder).
