Miracle Whip is a type of salad dressing that is made with different ingredients than mayonnaise. Mayonnaise is typically made with oil, egg yolks, vinegar or lemon juice, and salt. Miracle Whip, on the other hand, contains many of the same ingredients but also includes sugar, water, and many times, high fructose corn syrup. The taste is tangy and slightly sweeter in flavor compared to mayonnaise, and it is thicker. We would not recommend using it for chocolate mayo cake.
