I've lived in Hawaii for many years now and have always been curious about the local custom of baking a large sheet cake in a foil lined corrugated cardboard soda box. The reason locals use soda boxes is that they are the perfect size for a large one layer luau cake, and the box can be acquired free at one of our local grocery stores. 

I began to wonder if the cardboard box would catch fire in my oven? I asked my friend Blossom Poepoe, general manager of our local Kanemitsu Bakery, if there was a fire hazard using a soda box in my oven. Blossom said not to worry, it won't catch on fire, but she didn't say why. 

After considerable research, I found out that corrugated cardboard has a flash point of 451˚F. This means that if you bake a cake in a corrugated cardboard box (lined with foil, placed shinny side down), you don't have to worry about catching your house on fire. Most cakes are baked at 350˚F so it should be safe. I also found out that it is advisable to bake the cake on the center shelf of your oven because the heat is more even in that spot. Corrugated cardboard actually helps to insulate the cake, keeping it from burning and keeping it moist. You should also remember to only use the soda box once, because it gets crispy after baking in it the first time.

The good news is that because of the box, the cake is portable when covered with more foil, and the foil lining is helpful in removing the cake if you want to, then you can just throw away the box without having to clean it. Yes... I like that!

The following recipe is one that I usually bake in a 9 inch square baking dish, so I tried baking the same recipe in a foil lined soda box, just like the locals do, and it came out great. Naturally you can make a larger cake if your box is bigger, just increase the ingredients accordingly.

Ingredients:
1 tablespoon butter
1 cup sugar
1/2 cup canola oil
2 eggs
1 cup sour cream
1 1/2 cups all-purpose flour
2 teaspoons baking powder
1/2 teaspoon salt
1 (8 ounce) can crushed pineapple, drained or 1/2 cup fresh pineapple, chopped fine

Topping:
1/2 cup flaked coconut
3 tablespoons sugar
1/2 teaspoon ground cinnamon 

Procedure:
Line a 11 x 8 x 3 inch corrugated soda box with heavy duty foil (shinny side down), greased & floured to keep the cake from sticking to it.

In a mixing bowl, blend the sugar and oil. Add eggs, one at a time, beating well after each addition. Beat in sour cream. Combine the flour, baking powder and salt; add to the sour cream mixture. Stir in pineapple. Transfer the mixture to the foil lined, greased box. Combine the topping ingredients; sprinkle over batter. Place the box on a cookie sheet or sheet pan, and bake at 350˚F for 35-40 minutes or until a toothpick inserted near the center comes out clean. Cool on a wire rack. Makes 9 servings.

Note: Cover cake lightly with a sheet of foil during the last few minutes of cooking to keep the coconut from getting too brown. Also if you like nuts in your cake, add 1/2 cup of chopped and toasted Macadamia nuts, or pecans to the batter.


Soda Box Hawaiian Wedding Cake
Apparently this cake is not served at Hawaiian weddings and the name is not to be taken literally. It is just what it has traditionally been called in old Hawaiian church cookbooks and probably just means that it is for special occasions with the flavor of Hawaii. Regardless, it's moist and delicious!

Ingredients:
2 1/4 cups flour
2 cups sugar
3 eggs
dash salt
2 teaspoons baking soda
1 large ripe banana, crushed
20 ounce can crushed pineapple with juice
1 cup chopped pecans, optional

Ingredients for cream cheese frosting:

8 ounces cream cheese, softened
1/4 cup butter, softened
1/2 teaspoon vanilla extract
4 cups powdered sugar
2 to 4 tablespoons heavy whipping cream

Procedure:
Combine all cake ingredients in a bowl; mix by hand. Pour into a 13x9-inch heavy duty foil lined corrugated soda box (foil should be shinny side down), greased & floured. Bake at 350˚F for about 40-50 minutes until spongy. (It should bounce back when pressed.) Let cool. 

For frosting, beat together cream cheese, butter, and vanilla until well-blended. Gradually add powdered sugar and beat until completely incorporated. Add whipping cream until you reach the desired consistency; beat on high until light and fluffy. Frost cooled cake with cream cheese frosting. Store in refrigerator until ready to use. Makes 12 to 15 servings.

Note: You can top each slice of cake with a maraschino cherry to make it special.
