A one-way, between-subjects ANOVA revealed an overall effect of cookie type on liking, F(2, 62) = 5.54, p < .001, ?p2 = .155. Tukey’s honestly significant difference (HSD) test showed that those who ate a brownie batter cookie (M = 6.25, SD = 0.89) preferred it to either the vanilla (M = 4.98, SD = 0.78) or chocolate (M = 5.12, SD = 0. 82) cookie, both ps < .05. There was no difference in liking of the vanilla and chocolate cookies, p > .05.
