PURPOSE: More than 2 kinds of dough which contain a grain powder and water and are heated to an almost same temperature higher than 70°C are combined to form multilayers, thus producing a food product with an appearance stimulating appetites and uniform raising rate.

CONSTITUTION: Water is added to a grain flour until the water content becomes 30W60wt% to prepare 2 or more kinds of dough, which are heated to an almost same temperature of 85W95°C. They are piled with rollers into the multilayered product. The two or more kinds of dough are made distinguishable from each other so that they can form a clear multilayered structure. For example, the color, texture or raising rate is made different in each layer and they can be distinguished by the sense of taste and smell by using different flavors and spices. More concretely, edible colorants, beefstake plant, sesame, green laver and added to make colors and tastes different.
