Ingredients

Brownies

  • 250 g (1½ cups) semi-sweet chocolate, chopped
  • 150 g (⅔ cup) unsalted butter
  • 200 g (1 cup) granulated sugar
  • 4 large eggs, room temperature
  • 1½ tsp vanilla extract
  • 90 g (¾ cup) all-purpose flour
  • 30 g (¼ cup + 1 tbsp) unsweetened cocoa powder
  • ½ tsp salt

Chocolate Frosting

  • 230 g (8 oz) semi-sweet chocolate, finely chopped
  • 230 g (1 cup) heavy cream 30% fat
  • 8 g (2 tsp) honey or glucose syrup, optional

Instructions

  1. Preheat the oven to 175°C (350°F) and line a square baking pan with parchment paper.
  2. Melt the chocolate and butter together using a double boiler or microwave until smooth. Let cool slightly.
  3. Whisk the eggs, sugar, and vanilla with an electric mixer for 1 to 2 minutes until thick and glossy.
  4. Add the melted chocolate mixture and mix just until combined.
  5. Sift together the flour, cocoa powder, and salt, then fold gently into the batter until smooth.
  6. Pour the batter into the prepared pan and spread evenly.
  7. Bake for about 25 minutes, until the edges are set and the center remains slightly soft. Let cool completely.
  8. For the frosting, place the finely chopped chocolate in a heatproof bowl. Add honey or glucose syrup if using.
  9. Heat the heavy cream until just steaming, then pour it over the chocolate. Let sit for 2 to 3 minutes.
  10. Stir gently from the center outward until smooth and glossy.
  11. Cover and refrigerate for 3 to 4 hours, or until thickened to a spreadable consistency.
  12. Spread the frosting over the completely cooled brownies.
  13. Decorate with sprinkles while the frosting is still soft, then chill briefly before slicing for clean edges.

Storage : Store in an airtight container in the refrigerator for up to 4 days.
