They were quick to point out that none of their testers were fooled by the store-mix cakes, easily identifying the unusually uniform crumb and the ultra-fluffy texture that is created by the emulsifiers and other additives in the ingredients. Even so, five out of the eight mixes were still recommended: Betty Crocker Super Moist Butter Recipe Yellow Cake, Betty Crocker Super Moist Golden Vanilla Cake, Pillsbury Moist Supreme Classic Yellow Cake, Betty Crocker Super Moist Yellow Cake and Duncan Hines Moist Deluxe Butter Recipe Golden Cake. While the textures and colors of the winning cakes varied slightly from mix to mix, all had nice butter and vanilla flavors that make them worth eating, and only a very minimal (if any) artificial-ness to their flavor.
The cake mixes that didn't make the cut were panned by tasters for both poor texture and "insipid, stale" flavors. If you're going to buy a cake mix, stick with one of the brands above and avoid Duncan Hines Moist Deluxe Classic Yellow Cake ("a 'spongy Twinkie' "), Jiffy Golden Yellow Cake Mix ("dry and terrible") and King Arthur Flour Vanilla-Butter Cake Mix ("grainy, crumbly ... strong almond extract aftertaste").
