So I tried Ate Le's Chocolate Banana Cake with use of what I had on hand. I pretty much followed her recipe, but instead of the butter I used 3/4 of a cup of vegetable oil, light brown sugar as opposed to something darker (thus resulting in a lighter colour), sliced chocolate squares instead of choc chips and I added a teaspoon of cocoa powder for added chocolate goodness.
Needless to say, her's looks better (it's darker) and probably tastes better as well - but who cares. I achieved my goal: to bake something tonight. And now I have breakfast/lunch for tomorrow. Hooray for boredom and procrastination!
