Cake is a kind of food with special flavor and taste, mainly sweet and soft. Salad oil is a high-grade edible vegetable oil refined by degumming, decoloring, deodorizing (degreasing) and other processing procedures of various plant crude oils. It is clear, transparent and odorless, so salad oil is very suitable for cake making and will not affect and destroy the inherent flavor of cakes.

But peanut oil can't be used. The most important reason is that peanut oil has a strong peanut flavor, and the cake made will have a great peanut flavor, which will affect the original flavor of the cake and make people generally feel that it is not delicious.
