Oeey Gooey Butter Cake
For a homemade version of this, search in Grandmother's Kitchen for "yellow cake from scratch", and use that instead of the first 3 ingredients.

Ingredients
Cake
- 1 (18.25 ounce) box yellow cake mix
- 1 egg
- 1/2 cup (1 stick) butter, melted
Filling
- 1 (8 ounce) package cream cheese, softened

- 1 teaspoon pure vanilla extract
- 1 (16 ounce) box confectioners' sugar
- 1/2 cup (1 stick) butter, melted

Directions
- Preheat oven to 350 degrees F. Lightly grease a 13x9x2 inch baking pan.
- In the bowl of an electric mixer, combine cake mix, egg, and butter and mix well. Pat into the bottom of prepared pan and set aside.
- Still using an electric mixer, beat cream cheese until smooth; add eggs and vanilla. Dump in confectioners' sugar and beat well. Reduce speed of mixer and slowly pour in butter. Mix well.
