I had a few older bananas, and faced with the choice of banana bread or banana cupcakes, I chose the cupcakes. I used Banana Chiffon Cake recipe. Chiffon cakes are made with oil, with most of the leavening coming from egg whites.
My egg whites did not whip up. I probably did not check the pan or the whisk to make sure that they were absolutely residue free, so I will have to do that next time.
The cupcakes browned rather quickly, but they rose with a nice dome top. The bananas did something funky, as the inside seems to have tiny dark spots, almost like threads. I assume they came from the bananas.
The frosting? Well, strawberry frosting still eludes me. I learned that my frosting does need some fat in it. I started with cream cheese, strawberry puree, and strawberry jam. I mixed in 1.5 lbs of sugar, and it was still quite runny. I mixed in some shortening, and it firmed up. Will mix in shortening at the beginning next time.
I played with the frosting. I am deciding what type of decorations look and taste best on cupcakes. These were made with just a disposable piping bag with a large part of the tip cut off. Pretty! Will have pictures once I figure out a photo editing program :)
