Yes, I am keenly aware that this is not a meringue swirl a la Martha. But in my defense we had bananas that were about to go off, so what else was I supposed to do? When life hands you brown bananas, you make banana bread. Or cakes, in this case.
Now, the only thing left to decide on is frosting: peanut butter buttercream, salted caramel, or a nice smooth lemon glaze?
