Preheat your oven to 180°c and lightly grease a baking sheet with a little butter.

Cream together your butter and sugar until light and fluffy.

Warm the golden syrup a little (until it's runny), then add to the butter mixture.

Add your M&Ms/Smarties, then sift in the flour & bicarbonate of soda. Mix until combined.

Spoon out a heaped teaspoon amount and roll into a small ball before placing onto your pre-greased baking tray. Repeat with the rest of the mixture - you should get around 8-10 cookies.

Bake for around 10 minutes or until golden brown. Once cool enough to handle, transfer to a wire rack to cool completely.
