Preheat oven to 350 degrees F. Grease an 8x8 baking dish.
Either in a mixing bowl, or right into your 8x8 dish, mix all 3 ingredients together. Smooth the batter out and make sure it fills the whole pan.
Taste the batter. If it isn't sweet enough (as these are only sweetened with banana), you can add some honey, maple syrup, or chocolate chips.
Cook for 25 minutes.
Let sit for at least 10-15 minutes to cool and for the brownies to finish setting all the way.
