Ingredients
Method
- Preheat oven to 350°F (175°C) and grease a 9x13-inch pan. In a large bowl, mash bananas, then stir in eggs, oil, and vanilla. Add cake mix and cinnamon, stirring just until combined, about 1 minute.
- Pour batter into pan and spread evenly. Bake 30-35 minutes until golden and a toothpick comes out with moist crumbs. Cool in pan at least 10 minutes.
- Slice into squares, dust with powdered sugar if desired, and serve warm or at room temperature.
Notes
This cake is even better the next day, as the banana flavor deepens. Let it cool completely before wrapping to avoid sogginess. If you dust with powdered sugar, do it just before serving so it doesn't dissolve.
