For extra indulgence, serve with double cream or warm with a scoop of vanilla ice-cream, for a brownie a la mode.
For a dinner-party dessert, bake these brownies in a 22cm round cake pan and serve in wedges rather than squares.
Mix-ins: Traditional brownies have no mix-ins, or simply roasted nuts. Today, anything goes. So have fun! Adaptable, this brownie is a great fallback dessert. Here's inspiration for a sophisticated affair or everyday treat. Nuts (chopped roasted walnuts, pecans, pistachios or peanuts); candy bars (chopped frozen Snickers, Toblerone or Twix); spices (cinnamon); liqueur (orange-flavoured, such as Cointreau, or Kahlua) and others (orange or mandarin zest, glace ginger, dried cherries or dissolved instant espresso).
