1. Spray an 8x6x2 (6 cup) rectangular microwave safe baking dish with cooking spray. In medium bowl, combine mashed banana, applesauce, oil, sugars, and vanilla. Mix well.
2. Add flour, salt, and baking soda to the banana mixture until combined. Fold in chocolate chips.
3. Spread evenly into prepared baking dish and microwave on high for 5-7 minutes.
Our microwave is 1000 watts and it takes 5 minutes to bake. If your microwave doesn't have a carousel, rotate the baking dish 1/4 turn every 2 minutes.
It kind of reminds me of a cross between brownies and cake, but it's delicious!
