Mary Berry Double Chocolate Chip Cookies are soft-baked, chocolate-loaded biscuits made with cocoa and chocolate chips, offering a brownie-like texture inside and a lightly crisp outer edge. They are simple to prepare and bake beautifully every time.
150g unsalted butter (softened)
125g caster sugar
125g light brown sugar
1 large egg
1 tsp vanilla extract
200g plain flour
30g cocoa powder
1 tsp baking powder
½ tsp salt
150g chocolate chips
50g chopped dark chocolate (optional for extra richness)
Beat the butter, caster sugar, and brown sugar until pale, light, and fluffy to ensure a soft cookie texture.
Mix in the egg and vanilla extract until smooth and well incorporated.
In a separate bowl, stir together flour, cocoa powder, baking powder, and salt.
Fold the dry mixture into the butter mixture until a soft, chocolatey dough forms.
Mix in the chocolate chips and optional chunks, distributing them evenly.
Scoop small balls of dough onto lined baking trays, leaving room for spreading.
Chill the dough for 10–15 minutes if it feels too soft, which helps maintain cookie shape.
Bake at 180°C (350°F) for 10–12 minutes until the edges are just set.
Let the cookies rest on the tray for 5 minutes before transferring to a cooling rack.
