I love that this Banana Oatmeal Cake has NO oil in the cake… don’t you worry though! It’s moist and delicious all the same.

  1. You are missing ingredients. You say to cream butter and sugar but there is no butter in cake recipe. You never add the yogurt. You also say to add milk, again, not in cake ingredients list. Very confusing.

  2. Looks delicious! What will happen if I use regular whole wheat flour in lieu of whole wheat “cake” flour?

    1. Stephanie, you might have to hop over to Ruthie’s blog and ask her, not sure she will see it. I usually use white whole wheat which is just slightly lighter, so the effects of using regular might be that is a bit heavier. You could possibly make up for it with a tiny bit more leavening, but I don’t think it would hurt too much!… but to be sure go ask Ruthie!
