They were open in 1945.
But by 1953 (The earliest telephone book available at the Historical Society) they were out of business. What wasn't to love. Their cakes looked delicious and well made. Brownie is a perfect name for a bakery.
Maybe it was because they kept changing their telephone number and their location. Buddy remembers them as being across from where the library is now and their advertisements are for two other locations. Or maybe it was because they advertised in Knob Noster while they were located in various places in Warrensburg.
