INGREDIENTS
1 (18.25 ounce) package yellow cake mix
1 (3.5 ounce) package instant banana pudding mix
4 eggs
1 1/2 cups milk
1 1/2 cups white sugar
1/4 cup all-purpose flour
3/4 cup butter
3/4 cup shortening
3/4 cup milk
1 1/2 teaspoons banana extract
DIRECTIONS
Preheat oven to 350 degrees F (175 degrees C). Grease and flour 2 – 9×13 inch pans.
In a large bowl, stir together the cake mix and instant pudding. Beat in the eggs and 1 1/2 cup of milk. Divide the batter evenly between the two pans.
Bake in preheated oven for 15 to 17 minutes, or until a wooden toothpick inserted into the cake comes out clean. While the cake is baking, make the filling.
