1 yellow cake mix
1/2 cup butter (1 cube), melted
1 8 ounce package cream cheese, softened
2 teaspoons vanilla
1 stick butter, melted
3 cups powdered sugar
Combine crust ingredients and pat into a 9 X 13 pan. Beat cream cheese, eggs, and vanilla until smooth. Add butter and sugar. Mix well. Pour over crust. Bake at 350 degrees for 45 minutes.
Variations: use lemon cake mix and add lemon juice and zest to filling, use chocolate cake mix and add 3/4 cup peanut butter to the filling. I have never tried any of these, if you do, let me know how you like it!
