Ryan O'Keefe and Jude Bolton showed off their culinary skills this week, taking time out to make Christmas treats to give to those less fortunate this festive season.

The cupcake bake-off was for Sydney-based charity Oz Harvest, which collects excess food and delivers it free of charge to organisations that feed needy men, women and children in the local community.

The delivery of food by Oz Harvest enables recipient charities to redirect funds originally budgeted for food to other programs such as education, training and rehabilitation.
