Heather and Lori’s plans to launch their new Cupcake mix in retail stores – and finally give themselves a more reliable source of income – is threatened when 1000 units are delivered with the wrong baking instructions AND their retailer pulls out.  To save their mix and their company, Heather and Lori are challenged to prove they can sell 100 units of mix in five hours – leaving the Cupcake Girls to test how far they’ll go to grow their company.  Meanwhile, Brian and Kathie decide that it might be time to retire for good.
