Place dried apples in a saucepan; add water to cover. Bring to a boil; cover, reduce heat, and simmer for 25 to 30 minutes or until tender. Drain and mash apples. Stir in brown sugar, 1 1/2 teaspoons ginger, cloves, and allspice; set aside.
And another suggests spreading apple butter between the layers.
I think my mom used applesauce and spices but I really don’t remember. There are recipes online and some use dried apples that are cooked. I wish I could remember. My mom used to tell me to pay attention when she cooked because she wouldn’t be around forever. I wish I would have.
