Mother's Day Chocolate Cake: Retro Sunbeam Mixmaster Ad & Recipe

I adore Retro Advertisements, and this one is particularly close to my heart. My mother had a Sunbeam Mixmaster. So many cookies, cakes and brownies were made with that Mixmaster. I don't have my mother's Sunbeam Mixmaster, but I have my Mother-in-Law's -- the same model with all the attachments. I use my Kitchenaid Mixer mostly, but I love the functionality of that old Mixmaster War Horse. It still works, and I'll bet my mother-in-law got it in the early 50s.

So, for Mother's Day, here's a Sunbeam Mixmaster Mother's Day Advertisement from Life Magazine, May 1, 1950, complete with Chocolate Cake recipe. What are you making for Mother's Day?
