1 package (18-1/4 ounces) white cake mix
2 eggs1/3 cup vegetable oil
1 can (14 ounces) sweetened condensed milk
1 cup (6 ounces) semisweet chocolate chips

In a large bowl, combine the cake mix, eggs and oil. Press two-thirds of the mixture into a greased 13x9 inch baking pan. Set remaining cake mixture aside. In a microwave-safe bowl, combine the milk, chocolate chips and butter. Microwave, uncovered, until chips and butter are melted; stir until smooth. Pour over crust. Drop teaspoonfuls of remaining cake mixture over top. Bake at 350° for 20-25 minutes or until lightly browned. Cool before cutting.
