Pre-heat your oven to 180° (160° for fan ovens). Line your baking trays with parchment paper
Cream together your butter and sugar until combined
Add your golden syrup and stir
Measure out half your self-raising flour and sieve into your mixture
Whizz up your toffee in a food processor until you have small chips. Add to your dough and stir
Mix in your remaining flour. Then, using your hands, form your dough into a ball
Arrange your dough on your baking tray in 9-18 small balls (depending on the size you want your cookies). It'll be tempting to flatten them, but don't!
Bake for 12-15 minutes or until golden brown. Leave to cool completely so the cookies harden. Serve and enjoy!
