Can you make a whole batch of brownies in a skillet? You can and the results are incredible. You won't be disappointed with this skillet brownie recipe.
Put the butter and chopped dark chocolate in a large, heatproof bowl. Gently melt until smooth. You can use the microwave to do this, using 30 second bursts and stirring after each burst. Alternatively, you can put an inch of water in a pan, place the bowl on top (so that the water isn't touching the bowl) and bring to the boil so that the steam gently melts the chocolate, stirring as you go.
Whisk the sugar in. The mixture will thicken - graininess at this stage is fine.
If the mixture is hot, wait until it's just slightly warm before adding the beaten egg and vanilla. Whisk together until smooth.
Sift the flour into the bowl. Gently fold through until evenly combined.
Fold in the chocolate chips.
Generously grease a 32cm (12 inch) skillet.
Fill with the brownie batter and level off.
Bake for 35-40 minutes until set all the way across. A skewer pushed into the centre should reveal sticky crumbs.
Place on a wire rack and scatter the remaining chocolate chips on top.
You can serve the brownie warm, straight from the skillet in generous spoonfuls or, if you prefer, you can allow it to cool completely, then transfer to the refrigerator to chill overnight, where it will set, allowing neat slices.
