1

Heat oven to 350°F. Spray bottom of 15x10x1-inch pan with cooking spray.
2

In large bowl, beat cake mix, water, oil, eggs and cinnamon with electric mixer on medium speed 2 minutes, scraping bowl occasionally. Stir in mashed bananas; spread in pan. Bake 20 to 25 minutes or until toothpick inserted in center comes out clean. Cool completely, about 1 hour.
3

In 2-quart saucepan, heat butter over medium heat 5 to 8 minutes, stirring frequently, just until light golden brown. Watch carefully; butter can burn quickly. Remove from heat; pour into large bowl, and let stand 5 minutes.
4

Add powdered sugar, vanilla and 4 tablespoons milk; beat until smooth and creamy. If frosting is too stiff to spread, add additional milk, 1 teaspoon at a time. Spread frosting over cooled cake. Before serving, sprinkle with Toppings. To serve, cut into 6 rows by 4 rows.

Expert Tips

For best success with this recipe, be sure to use a 15x10-inch pan with at least a 1-inch rim so there is less risk of cake batter spilling over while baking.
Peel and freeze your overripe bananas in a large resealable freezer bag. Take them out of freezer to refrigerator the night before, and you’ll have bananas ready to mash for your recipe. Drain any excess liquid before mashing, if necessary.
