Melt gently over a pan of simmering water or in short microwave bursts.

Laura's Top Tips for This Recipe
I find it best to use really good quality Whitakers dark chocolate and melt it gently with the butter. When I tried rushing the melting or using lower quality chocolate the brownies lost that deep, rich flavour.
Line your tin well with baking paper that overhangs the sides. It makes lifting the whole slab out so much easier once it has cooled and stops any sticking at the edges.
When I tried baking for the full 25 minutes they were a bit firmer than I like. I now pull them out at around 20–22 minutes when the edges are set but the centre still looks slightly soft. They continue to set as they cool and stay beautifully fudgy.
Let the brownies cool completely in the tin before slicing. I know it is tempting to cut them warm but they slice so much cleaner once fully cooled and the texture is even better.
A tiny pinch of salt in the batter makes the chocolate taste even more intense. I always add it now and it really lifts the whole flavour.

A Brief History of Chocolate Brownies in the UK
Chocolate brownies started in the United States in the late 1800s.
A common tale points to Bertha Palmer, who asked chefs at the Palmer House Hotel in Chicago to make a portable treat for the 1893 World's Columbian Exposition.
The first printed recipe appeared in the 1896 Boston Cooking-School Cook Book by Fannie Farmer, though that version lacked chocolate and resembled what people now call blondies.
By 1907, recipes with more eggs and chocolate became standard.
In the UK, chocolate began as a drink, but by the late 1800s, it featured in cake recipes. Brownies arrived in the early 1900s, with British food writer May Byron sharing adapted versions in her 1915 Cake Book, using treacle instead of molasses and walnuts over pecans.
UK brownies often include nuts and spices for a richer taste, fitting local preferences.
Over time, they grew popular at tea times and as everyday treats, with modern twists like added espresso or sea salt.
