Next, the method includes mixing more of the fiber ingredients and optional ingredients, such as cheese powder, whey protein powder, salt, yeast enhancer, and paprika. The bake- stable filling has a baked density of less than 1.875 g/cm3 and a baked water activity level of less than 0.35. The fiber ingredients have a particle size of less than about 150 μm. The fat ingredients of the filling substantially refrain from spreading to the dough component during or after baking so that the dough component remains crispy.
