My husband is visiting his father this weekend to deliver Christmas presents and spend some time with him in his new assisted living apartment. I just realized that it is my father-in-law's birthday next week and thought a small cake might be a nice thing to take along. He has a small appetite and I have a disposable 8x8 pan with a cover in my pantry. He loves desserts but is quite satisfied with simple Entenmann's cakes (I don't believe my mother-in-law ever baked).
Please suggest a simple cake recipe that I can bake in this small sized pan.
