Condensed milk candies

So growing up my grandma made these candies they were brown and I don’t exactly remember the flavor and she’s sadly passed so I can’t ask her. Awhile back I had lunch with my family including her sister she’s a lot older so her memory isn’t what it used to be but she said that it a simple 2 ingredient candy condensed milk and baking soda and roll it into the balls. They’re not coming out exactly how I remember especially color wise but I was a kid so maybe I remember the color wrong so as usual I’m on Reddit looking to see if anyone might know what it could be any help would be great and much appreciated, thank you.
