Ingredients
Method
Preheat the oven to 170C and line an 9 inch/ 23cm cake tin with baking paper
Mix the butter and sugar
- Measure the butter and sugar out then add to a mixing bowl or freestanding mixer. Mix them together using the paddle attachment, a hand held mixer, or wooden spoons until the eggs and butter are light and fluffy.
Add the eggs and vanilla extract
- Break the eggs, one at a time, into a small bowl. Add them to your bowl, mixing it a little between each addition.
- Turn the mixer down to a slower speed and add the vanilla extract into the bowl.
Add the remaining ingredients
- Measure the flour, salt, and bicarbonate of soda into a small bowl. Add these into your large bowl.
- Mix everything together until you have a smooth dough. If you need to, use a spatula to scrape the mixture down from the sides of the bowl.
- Add in one pack of the M&Ms or chocolate chips to your dough mixture. Give it one last mix so that everything is nicely combined.
Make the giant cookie
- Pour the cookie dough into your prepared cake tin. Press down the mixture with the back of a spoon. Sprinkle a few more M&Ms on top until it looks nice and colourful.
Bake the cookies
- Pop the giant cookie in the oven for roughly 15-20 minutes. It’s ready when the edge has turned golden brown and they’ve flattened down. It’ll still be a bit gooey in the middle but that’s how I like them. Cook it longer if you prefer a more crispy cookie.
- Leave it in the cake tin to cool slightly, then move it to a wire rack to cool completely.
