Millie’s Cookies giant cookie recipe


2 eggs
1 tsp salt
1 tsp vanilla
390g plain flour
1 tsp baking soda
235g unsalted butter
340g chocolate chips
110g granulated sugar
255g light brown sugar


100g butter
150g icing sugar
25g cocoa powder


  1. Preheat oven to 160C.
  2. Using a stand mixer or electric hand whisk, combine the sugar and butter and mix together until pale and fluffy.
  3. Add in the eggs one at a time and mix until combined.
  4. Once the eggs are fully mixed in add the vanilla and mix.
  5. Add the flour, baking powder and salt and mix slowly until evenly combined.
  6. Pour in chocolate chips and give it a final mix until your dough has formed.
  7. Wrap your cookie dough in cling film and leave to chill for two hours in the fridge.
  8. Weigh out 400g of cookie dough and roll into a ball (you’ll probably have enough dough for two giant cookies).
  9. Place the ball in the centre of your baking tray (lined with baking parchment paper) and gently press down into a large puck shape.
  10. Bake for 30-35 minutes until golden brown on the edges.
  11. Leave to cool for 1 hour before decorating.
  12. While your cookie is cooling you can make your chocolate buttercream by beating the icing sugar, butter and cocoa together until smooth.
  13. Put your buttercream into a piping bag and get decorating!
