This recipe for Banana Oatmeal Crumb Cake comes courtesy of Carol at AllRecipes.com. Many of my recipes start by having a bunch of ingredients I want/need to use before they go bad or if because they're all I have left in the house. My only change to the original recipe is I left out the walnuts. I'm not a big fan, nor did I have any around. I had some bananas that were over-ripe, and was craving a coffee cake-like recipe. This cake is delicious, and can be made with stuff you'll already have around the house. However, my topping wasn't very crumb-y like a crumb cake. I'm not sure what to do there, suggestions appreciated. I enjoyed with a nice hot cup of black coffee (how's that for a pairing).
