Preheat oven to 350°F. Lightly grease an 8-inch square baking pan. Line with parchment paper, leaving overhang on all sides. Set aside.
In a large bowl or stand mixer, combine banana and vegetable oil. Mix in granulated and brown sugar, followed by the egg and vanilla. Mix until just combined. With mixer running on low, slowly add all dry ingredients. When batter is just combined, add yogurt. Mix until no streaks remain. Transfer batter to prepared baking pan. Use a small offset spatula to create an even layer of batter. Bake for 25-30 minutes or until golden and a toothpick comes out clean when inserted into the center of the cake. Cool in pan, set on a wire rack.
When cake is completely cooled, prepare frosting. In a medium bowl, beat together cream cheese and butter until light and fluffy. Mix in cinnamon and brown sugar, followed by powdered sugar. Spread on cake with an offset spatula.
Slice and serve. Store remaining cake in an airtight container for up to several days.
