It depends on the policy of the custom cake baker. Generally, bakers offer cake tasting for significant events such as weddings or grand birthday parties. They may require you to meet some qualifications before you can avail of their cake tastings, such as the minimum number of attendees, a booked venue, and the total order. It’s best to consult your Tasker about this, and they may be able to provide you with samples of their different cake flavours.
