  • 2 pieces eggs Essential for richness and helping brownies rise.
  • 50 g cocoa powder Use high-quality for a deep chocolate flavor.
  • 50 g plain flour Gives structure without making them too dense.
  • 1/2 tsp baking powder Ensures brownies are light and fluffy.

  • 1 tbsp coconut oil Adds flavor and helps maintain a smooth topping.
  • 180 g marshmallows Creates a delightful contrast with the brownie.

Preparation

  • Preheat the oven to 150°C (fan bake) and line a 20 cm square tin with baking paper.
  • In a large microwave-safe bowl, melt the butter completely.
  • Mix in the caster sugar, vanilla essence, and eggs until glossy and well combined.
  • Sift in the cocoa powder, plain flour, and baking powder, then gently fold until just combined.
  • Spread the batter evenly in the prepared tin and bake for 25 minutes.
  • Allow to cool in the tin for at least 15 minutes.

Topping Preparation

  • In a heatproof bowl, combine the milk chocolate and coconut oil and microwave until melted, about 45 seconds.
  • Let the mixture cool slightly, then stir in the marshmallows to coat them evenly.

Assembly

  • Pour the topping over the cooled brownie base, spread evenly, and chill in the fridge for at least 2 hours.

Notes

For best results, chill the sliced brownies before serving. Avoid over-mixing the batter and ensure the brownie base cools sufficiently before adding the topping.
