Caster sugar dissolves much faster and blends more smoothly, making it useful in recipes that call for a fine texture, including meringues and sponge cakes. While regular sugar works well for most kitchen tasks, baking recipes benefit from the smoother texture of caster sugar.

Cocoa Brownies by Shrilatha

The ingredients for cocoa brownies are readily available in your pantry and are quite simple to prepare.


  • 1/2 cup butter (measure and melt (read notes)
  • 1 cup +2 tbsp caster sugar (or super fine granulated sugar)
  • 2 large eggs (room temperature)
  • 1 large egg yolk (room temperature)
  • 1 cup all-purpose flour
  • 3/4 cups cocoa powder
  • walnuts (optional)


  • Preheat your oven to 170°C and grease the baking pan. (You can use a baking mould or butter paper as a substitute)
  • Measure the butter and melt it, then set it aside to cool until just warm to the touch before use.
  • In a large bowl, whisk together the melted butter and caster sugar until smooth.
  • Add in the eggs and whisk until well blended.
  • Sift in the all-purpose flour and cocoa powder, then fold until no flour streaks are seen. The batter will be very thick, but that's okay because that's how it should be for fudgy brownies.

  • Transfer the brownie batter to the prepared pan and spread it out evenly.
  • Place the pan in the middle rack of the oven and bake for 25 minutes.
  • Remove the pan from the oven and let it sit for at least 15 minutes before removing the brownies from the pan and letting them cool completely on a wire rack.
  • Once completely cooled, use a sharp knife to cut the brownies into slices.
