sammii78. Hi. I have never made or heard of a Fruit Cake being made with white sugar, that does not mean it cant be used.
I am only guessing that white sugar may make the cake a little sweeter and paler in color.
Would very much appreciate your opinion on the flavor and texture by using the white sugar.
Thank you so much for your question. Hope it turns out o k .
