Combine liquid ingredients in blender (half & half, golden syrup, vanilla) and blend on low until combined. This may take a couple minutes for the golden syrup to dissolve into the mixture.
With the blender on low, gradually add the dry ingredient mixture and blend until combined.
Freeze according to your ice cream freezer’s directions.
When ice cream is “done” transfer to another container and freeze in the freezer overnight to finish hardening.
