One of the flavors of Klein's parve ice cream is "Cookies and Cream" which contains cookie crumbs or bits which are sprinkled through areas of vanilla frozen dessert. The appropriate brocha rishona on this product is shehakol, but it is k'dai [worthwhile] to make a borei minei mezonos on another product and have in mind at that time to be motzi the cookie part of the ice cream as well.
Why is the appropriate bracha rishona shehakol? I thought that mezonos was not batel in a mixture because it is always chashuv (see Mishneh Berurah 212:1 or Aruch HaShulchan 212:1)? What is the logic behind Rav Belsky's ruling?
