Chocolate Oat Bran Cake (Diabetic)

READY IN: 1hr 20mins
Recipe by Outta Here

A healthy snack cake. Do NOT sub Splenda for the 1/3 cup sugar in the dry ingredients. The sugar helps keep cake moister. Eat plain or with a dollop of sugar-free Cool Whip.

I made this to fulfill a request for a bran birthday cake. Test run of recipe as written, subbing sugar for splenda (using 2/3 cup sugar total) as diabetes is not a concern and splenda is pricey, and using whole-wheat flour. As is, the cake was incredibly dry, but still tasty. Good for snacking or breakfast but not dessert-like. For the official birthday cake, I again used all sugar, adding an additional 1/3 cup for one cup total, used half all-purpose and half whole wheat flour, and added an additional egg and 1/3 cup more oil. Frosted with cream cheese frosting, sprinkled with walnuts and sliced almonds. It was amazing! Seriously, one of the moistest, yummiest chocolate cakes ever. When I make it again I will only use 2/3 c sugar, the addition was unnecessary.
