This easy-to-make snack cake recipe is filled with crushed pineapple, coconut, and walnuts and topped with a cream cheese frosting. It's a sweet addition to picnics and potlucks.
Heat oven to 325°F. Coat a 13 x 9 x 2-inch baking dish with nonstick spray.
In a large bowl, mix flour, granulated sugar, baking soda, eggs, pineapple with juice, coconut and 1 cup of the walnuts. Stir with a wooden spoon until just combined and all ingredients are moist.
Spoon mixture into prepared pan. Bake at 325°F for 35 to 40 minutes or until a toothpick inserted in the center of the cake comes out clean. Remove from oven and cool on a wire rack.
In a bowl, beat butter and cream cheese until smooth. Gradually beat in confectioners' sugar and vanilla until smooth. Frost cooled cake with the cream cheese mixture. Garnish edges with chopped walnuts, if desired.
