1 white or yellow cake mix
1/3 cup oil
1 cup semi-sweet chocolate chips
1/4 cup butter/margarine
1 can sweetened condensed milk
Preheat oven to 350 degrees F. Lightly grease the bottom of a 9x13" pan. In a medium size bowl, mix the first three ingredients together. Press 2/3's of the cake mixture into the bottom of the prepared pan. In a different microwave-safe bowl, combine the last three ingredients. Melt in the microwave for one minute; then stir until all melted. Pour chocolate mixture over cake mixture in pan. With the rest of the cake mixture, take tablespoonfuls and press flat, then lay on top of the chocolate mixture, leaving space in between the flat pieces to form an aesthetic-looking dessert! bake for 20-25 minutes or until a toothpick inserted comes out clean.
My mother-in-law found this recipe in a book complied from her ward in Moroni, UT; Karla Bench is author of these delicious treats. I have found they are best after cooling completely. Even after refrigeration or the next day they are so good. My husband doesn't like semi-sweet chocolate, so I use milk chocolate chips and they taste just as good.
