To make cake:Preheat oven to 325. Beat all cake ingredients together with a mixer on medium-high until smooth. Pour into a greased and floured 9x12x2 inch baking pan. Bake at 325 for 35 minutes or until tester inserted in the center of the cake comes out clean. Let cool on wire rack. While the cake is in the oven, prepare the frosting.
To make frosting:In the top of a double boiler over simmering water, combine butter, chocolate chips, condensed milk, and karo syrup. Cook over the simmering water, stirring only occasionally, until smooth, about 20 minutes. Remove from hot water and beat with an electic mixer until smooth.
