Brownies are the classic American dessert. They're a perfect way to finish off a picnic, barbecue, or dinner party. (DK tip: Brownies are better when slightly undercooked, as they retain their moist interior and store better, too.)
PREP TIME: 15 mins
COOK TIME: 40 mins, plus cooling
8 tbsp butter, melted, plus extra for greasing
1⁄2 cup sugar
1⁄2 cup light brown sugar
1 tsp vanilla extract
3⁄4 cup all-purpose flour
11⁄2 cups cocoa powder
1⁄4 tsp baking soda
8oz (225g) dark chocolate chips
1. Preheat the oven to 300ºF (150ºC). Using an electric hand whisk or mixer, combine the butter, sugars, eggs, and vanilla extract in a large bowl until well mixed.
2. In a separate bowl, combine the flour, cocoa powder, and baking soda. Stir the flour mixture into the butter mixture, one-third at a time, making sure that it is well incorporated before each addition. Mix in the chocolate chips.
3. Grease and line a 9 x 9in (23 x 23cm) baking tray or brownie pan and spoon the batter into it. Use a spatula to spread the batter evenly, ensuring the corners are filled.
4. Bake for 35–40 minutes, or until cooked through and firm. Remove from the oven and leave the brownie to cool in the pan, then turn out of the pan and cut into 16–20 squares.
