Humdinger Cake - cooking recipe

Ingredients

1/2 cup butter, softened
1 (15.25 ounce) package yellow cake mix (such as Betty Crocker(R))
3 eggs
1/2 cup water
1 (8 ounce) can crushed pineapple with juice
2 large very ripe bananas, mashed
1 cup chopped pecans (optional)
1 cup shredded coconut (optional)
1 (16 ounce) container cream cheese frosting

Preparation

Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9x13-inch baking dish.
Beat butter in a bowl using an electric mixer until light and fluffy. Add cake mix, eggs, and water; mix until batter is just combined. Stir pineapple and bananas into batter. Fold pecans and coconut into batter; pour into the prepared baking dish.
Bake in the preheated oven until a toothpick inserted in the center of the cake comes out clean, 35 to 45 minutes. Cool cake in the dish for 10 minutes before turning onto a wire rack to cool completely, about 30 minutes.
Spread cream cheese frosting over cooled cake.
