I used 1 1/2 cup white whole wheat and1/2 cup all-purpose flour and used sweetened apple sauce. With these substitutions they are pleasantly dense, and lightly sweet. They would be a good option for toddlers. A bit of salt would improve the flavor.
I made this recipe with a few modifications-while putting the dry ingredient in, I realized there was no sugar (aside from the applesauce). I used 1/4 c. white sugar and 1/4 cup splenda. Instead of raisins, I used 1/2c. walnuts and 1/2 c. dark chocolate, and also whole wheat flour. SO good!
