1/2 cup butter or margarine
1 (2 ounce) package cream cheese, softened
1 (3 ounce) package instant vanilla pudding mix
1 (3.2 ounce) package white chocolate flavored Jell-O
Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9x13 inch pan.
In a large bowl, mix the butter, cream cheese, pudding mix and white chocolate gelatin. Stir until well-combined. Pour the mixture into the prepared pan.
Bake in the preheated oven for 1 hour, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool completely.
