Determine your design plan.  Place your silicon sheet or parchment paper on your cookie sheet.

Pour and spread your base color on the cookie sheet.  We did the strawberry as the base. 

Fill a pipping bag with the vanilla yogurt.  Cut the end of the pipping bag. Add the design.

 Use a stick to swirl the colors.

Cover and freeze for 4 hours.

Remove from freezer and break into pieces and ENJOY!
