150 g Softened butter (1+⅓ sticks)
130 g Caster sugar (⅔ cup)
100 g Soft light brown sugar (½ cup)
1 Medium Egg
1 Teaspoon Vanilla extract
250 g Self-raising flour (2 cups)
100 g Mini red and green M&Ms (½ cup) I bought 2 bags and picked out the green and red ones
25 g Milk chocolate chips (2 tablespoons)
25 g White chocolate chips (2 tablespoons)

Preheat your oven to 180°C/350°F (or 160°C/320°F for fan or convection ovens) and line an 8x10 or 8x8-inch tin with baking paper.
Add the butter to a bowl with the caster sugar and brown sugar. Mix to make a thick paste, using an electric whisk or stand mixer to assist if required.
Add the egg and vanilla extract and mix well until smooth.
Add all of the self-raising flour and mix it in. When it starts to come together, use your hands to press it into a ball of dough. If the dough is too sticky, add more flour. If it’s too dry, add a splash of milk.
Add the mini M&Ms and the chocolate chips, saving a few for the topping.
Press the dough into your lined tin then top with leftover M&Ms and chocolate chips.
Bake for 22-25 minutes, until the cookie is golden brown all over and slightly pulling away from the edges.
Leave it in the tin to cool completely then pop it in the fridge for 1-2 hours, until solid. This will give you sturdy, chewy bars that won't break.
Remove the cookie from the tin, cut it into squares and enjoy!
