My brother asked for this, so I figured I’d share it here.
Cake
Peel and slice apples, and place them on the bottom of a greased, and floured pan, then just add a yellow cake mix batter. I don’t remember if she used cinnamon, I do.
Sauce
Blend over low heat, 1 stick butter 2 TbLs. Flour, when the butter is melted, SLOWLY add 1 cup of boiling water, cook until thick. Add 2 TbLs. sugar, and a sprinkle of Nutmeg.
Note: If the heat is to high, or you add the water to fast, it will break.
