I love this cake and make it every year on the arrival of Spring.
3 cups all-purpose flour
1 teaspoon baking soda
2 cups sugar
1 teaspoon salt
1 1/2 cups canola oil
1 (8 ounce) can crushed pineapple, drained
2 cups mashed bananas
1 cup chopped walnuts
1 (8 ounce) package cream cheese, softened
1/4 pound butter, softened
1 pound confectioners' sugar
1 teaspoon vanilla extract
Preheat oven to 350 degrees. Grease and flour two 9-inch cake pans.
Sift together the flour, sugar, baking soda and salt. Set aside.
In a large bowl, combine the oil, eggs, pineapple, bananas and nuts. Add flour mixture, and mix together by hand.
Pour batter into prepared pans. Bake in preheated oven until a toothpick inserted in center of each pan comes out clean, about 1 hour. Remove from oven and allow to cool on racks.
Prepare the frosting by blending together the cream cheese, butter, sugar and vanilla until smooth. Evenly spread frosting on middle, sides and top of cake.
